Blockchain Development Services for Healthcare: A Non-Technical Buyer’s Guide

Healthcare leaders have had enough of the vague chatter about Web3--they're looking for a concrete plan they can actually use. This guide dives into the latest updates from the U.S. We're diving into health IT regulations, standards, and some hands-on projects to help you make sense of it all. We'll break things down into straightforward options, solid frameworks, and key questions for vendors. By doing this, you'll be all set to launch your blockchain programs by 2026!

Why 2025-2026 is different: four regulatory shifts you can’t ignore

**Providers are really feeling the heat from information blocking penalties these days. So, back in June 2024, HHS introduced some “appropriate disincentives” that are tied to Medicare programs and how they’re shared publicly. So, they started looking into things on July 31, 2024, and you can expect the new disincentives for the MSSP to start making an appearance in January 2025. Thanks to immutable and queryable audit trails, we're really cutting down on risk exposure. (ama-assn.org).
**TEFCA just got a fresh update! Now, it's all about FHIR and there's a new deadline for security requirements. ** The Common Agreement Version 2.0. 0/2. Step 1 is all about setting up FHIR-based exchanges with a handy Facilitated FHIR Standard Operating Procedure (SOP). We're excited about the QHIN-to-QHIN FHIR pilots that are happening through 2025! And just a heads-up: If you’re planning to get on board with TEFCA FHIR, you'll need to have the FAST UDAP security Implementation Guide in place by January 1, 2026. So mark your calendars! (rce.sequoiaproject.org).
Nowadays, a lot of payers really rely on prior authorization APIs. They’ve become essential tools for managing approvals. Thanks to CMS-0057-F, we’re starting to see some new requirements pop up for Patient, Provider, Payer-to-Payer, and Prior Authorization APIs, all based on FHIR R4. The cool part? Most of the deadlines for these changes are lined up for January 1, 2027. Just a heads up, some of the operational timelines, including how quickly decisions get made, are set to kick off as soon as January 1, 2026. Hey, you know what? Using blockchain for tracking the origins of products could seriously boost these processes. (cms.gov).

So, it looks like the DSCSA’s "stabilization" and exemptions are going to stick around for a while--probably until late 2025 or even into 2026. Hey there! So, here’s the scoop: the FDA has decided to roll out a phased approach for enforcement that goes beyond November 27, 2024. What does that mean for wholesalers? Well, they’ve got until August 27, 2025, to get their act together. Bigger dispensers have a little more leeway--they have until November 27, 2025. And for the smaller dispensers, they can breathe easy until November 27, 2026. So, there’s plenty of time for everyone to adjust! Using enterprise blockchains and reliable audit logs can really enhance the security of drug distribution and make it easier to track everything. It’s all about making sure the system works smoothly and efficiently across the board. (fda.gov).

Cyber Context

In 2024 and 2025, we really witnessed a shocking spike in healthcare data breaches. One of the most talked-about cases was the incident with Change Healthcare, which grabbed a lot of attention in the news. Because of this, regulators are really starting to take a closer look at audit controls. To simplify things during OCR audits and incident investigations, many businesses are now leaning on tamper-evident logs and verified data integrity. These tools really help to keep things transparent and trustworthy! If you want to learn more about these data breaches, feel free to check out the details here. It’s packed with info that you might find interesting!

When blockchain is the right tool (and when it isn’t)

Think about using blockchain if you’ve got a bunch of different organizations that need to work together. It’s perfect for situations where you want to: (a) keep track of changes that everyone needs to agree on; (b) rely on a common truth without any single person being in charge; (c) maintain a clear history for auditors to look at; and (d) cut down on duplicate data. It really helps streamline everything! If you’re just working with single-org databases and mainly focusing on crunching numbers for analytics, or if you need real-time clinical decision support where timing is everything, then it’s probably best to steer clear of blockchain.

High-Fit Healthcare Use Cases in 2025-2026:

Looking ahead to 2025 and 2026, there are some really cool healthcare use cases that are starting to shine. Here's what we can look forward to:

Standards that should shape your RFPs (updated for 2025)

FHIR: So, we’re focusing on R4 for APIs right now. If you’re working on population exports and cohorts, definitely take a look at the Bulk Data Access Implementation Guide version 3 - it’s currently up for the STU3 ballot! Just wanted to give you a quick heads-up: even if your systems are still on v1... x or v2. Hey, X! I think it’s smart to start thinking about v3 semantics. For more info, just check out build.fhir.org. It's all laid out there!
TEFCA: So, we’ve got the Common Agreement version 2. 1 is definitely where the magic happens, especially when you pair it with the Facilitated FHIR SOP. Hey there! Just a quick reminder for those of you getting on board with FHIR as part of TEFCA: make sure you keep in mind that the FAST UDAP Security IG is going to be a must-have by January 1, 2026. It's important to stay ahead of the game! Hey, if you're interested, you can find all the details over at rce.sequoiaproject.org. It's got everything you need to know!
Identity and Access: So, there's this cool thing called the HL7 Interoperable Digital Identity & Patient Matching IG v2.

0. So, we've got 0 on the ballot, and our goal is to hit IDIAL1. We've got an 8+ rating for patient access, and when it comes to workforce needs, we're sitting at AAL2+. If you want to learn more, check out build.fhir.org. You’ll find some great info there!

Verifiable Credentials (VC): Don't forget to check out the W3C VC Data Model 2! It's definitely worth your time. It looks like we're aiming to have a recommendation ready by May 15, 2025. This is going to be super helpful for creating portable, privacy-friendly credentials, like e-consent documents or licenses. If you want to dive deeper into it, check out the details over at w3.org.
Zero Trust: Make sure to check out the NIST SP 800-207 guidelines--they’re super important! It's really about bringing together blockchain access and how we run our nodes with the principles of Zero Trust Architecture (ZTA). This involves things like policy decision points, keeping authorization ongoing, and breaking things down into micro-segments. It’s a smart way to ensure everything is secure while still being flexible. Dive deeper at csrc.nist.gov.
HIPAA/Part 2: We really should improve our audit controls--make sure to take a look at 164 for some guidance. Make sure you're on top of the 312[b] and get everything in line for the Part 2 rule by February 16, 2026. You've got some time, but it's best to start prepping now! This means getting everything in sync with HIPAA when it comes to consent, breaches, and enforcement. If you want to dig deeper and get more info, check out law.cornell.edu. They’ve got a ton of details waiting for you!

Proven examples to emulate (with numbers, timelines, and tooling)

What worked: The folks at the Synaptic Health Alliance have been doing a great job sharing provider updates using this permissioned ledger. It’s really helping to ease that “validation fatigue” everyone talks about, thanks to their smart allocation model. Right now, they're up and running in several states, including Texas, Colorado, Florida, Michigan, New York, Ohio, and Tennessee. They've got more than 2 million records, and one member even mentioned seeing an incredible ~500% annual return on their investment. That success came from cutting down on directory operations and avoiding those pesky penalties! (synaptichealthalliance.com).
Why blockchain: One of the coolest things about blockchain is that everyone involved can see the same verified updates. It creates a level playing field where transparency rules! It really helps keep everything open and clear. That way, no one person can say they "own" the truth! This really backs up what the CMS findings showed--more than half of the directory locations have had inaccuracies in the past. (synaptichealthalliance.com).
Stack pattern: So, we’re checking out a consortium network that's set up on a managed enterprise stack. Picture something like Hyperledger FireFly mixed with Fabric or Besu, and it’s all being hosted on a platform like Kaleido. Pretty cool, right? So, this setup basically opens up the FHIR/Plan-Net APIs so that they can be accessed from outside. FireFly really nails it when it comes to syncing off-chain data with on-chain proofs. This is crucial for maintaining privacy and ensuring everything runs smoothly. (hyperledger.github.io).

What to include in your RFP: Hey, don't forget to ask for the Plan-Net compliant directory APIs. It'll make things a lot easier! Hey there! Just a quick note: make sure to ask for the publish/subscribe proofs every time there's an update. You know, stuff like the hash, timestamp, and who signed off on it. And don’t forget to include those audit queries for the regulators too! Hey, just a quick reminder! Make sure to include the onboarding SLAs. We want to shoot for getting that first data contribution in 30 days or less. Also, let’s establish some ROI targets that focus on reducing those contact attempts.

2) DSCSA enhanced security: package‑level traceability and verifications

What’s Happening: So, the FDA is kicking off some new rules for drug distribution, and it’s going to be a bit of a transition period. From November 2023 to November 2024, they’re working through a stabilization phase to make sure everything runs smoothly. Great news! They’ve got some tiered exemptions on the table. Alright, so here's the deal: wholesalers need to get their act together by August 27, 2025. For the bigger dispensers, they've got a bit more time, with a deadline of November 27, 2025. And if you're dealing with the smaller dispensers, they’re all set until November 27, 2026. So, mark your calendars! When you’re mapping out your plan for 2025-2026, it’s super important to demonstrate that you’ve got a solid grip on managing interoperable electronic tracing, verification, and alert notifications. The key here is to make sure everything runs smoothly without disrupting the supply chain.

Solid foundation: The MediLedger FDA pilot really showed how well blockchain can handle tracking ownership changes without spilling any secrets among the 25 pharma companies involved. This could be a great go-to guide for keeping track of events across different companies. If you're looking for more info on their project, you can check it out here. It's definitely worth a look!
Stack pattern: It's super important to keep your serialized product data neat and tidy in your ERP/WMS. Don’t forget to track all those transaction and verification events--basically, think of them like hashes and pointers on a secure ledger. And remember, you’ll want to make your EPCIS/DSCSA interfaces accessible too. To keep things secure and transparent, you might want to pair this with something like Azure Confidential Ledger. It gives you those tamper-evident and regulation-friendly receipts that are super handy. Plus, it won’t break the bank--it's only about $3 a day for each instance. Just a little investment to ensure everything stays legit and intact! If you want to dive deeper into it, check it out here. You’ll find all the details you need!

Checklist for 2025 Pilots:

Make sure you can confirm the trading partners for cross-trading according to the Service Level Agreement (SLA) we've agreed on.
Show off a secure event history that’s tough to tamper with, complete with a hash anchor, and include an easy way to export data for regulators. Let's run a little simulation to see how we can deal with exceptions, such as handling returns for items that are still sellable or figuring out what to do with products that seem a bit sketchy or possibly fake. We'll be using the shared ledger approach for this. If you want to dive deeper into this topic, take a look at the details here.

3) Prior authorization and clinical data provenance (API-first, ledger-backed)

What You Should Know: Alright, here’s the deal--requirement CMS-0057-F is really nudging payers to step up their game. They need to start implementing FHIR-based APIs for a bunch of important stuff, like handling Patient, Provider, Payer-to-Payer data, and Prior Authorization. So, a lot of these APIs are aiming to be compliant by January 1, 2027. But honestly, it's a good idea to start getting your operations in gear by January 1, 2026. That way, you'll be ahead of the game! That's where blockchain steps in! It really helps keep things running smoothly between different organizations. You know, like when you send a request, get more info, and then make a decision. Plus, it creates a rock-solid audit trail that clearly shows what's been approved or denied. Pretty neat, right? For more info, just click here!

Getting There: So, here’s the plan: we want events like CRD, DTR, and PAS to seamlessly contribute to a consortium ledger. This ledger will safely keep track of all the requests, attachments, and decisions involved. It's all about making sure everything is secure and organized! So, the real info is going to hang out off-chain, in your payer or provider systems. Just double-check that the identities in the ledger line up with what’s in the HL7 Identity IG (IDIAL1). Every event is tagged with the context of both the organization and the user, including 8+/AAL2+. If you’re looking for more details, you can check it out here. Happy exploring!

Pilot Success Metrics

Median Time for Prior Authorization Decisions: Take a look at how this stacks up against the benchmarks set by CMS.
Percentage of Requests Handled Automatically: This refers to the requests that can be processed without any help from a human.
Appeal Rate Delta: Let’s dive into how the appeal rates compare and see if we can follow the decision-making trail when we go through the audits.

Verifiable consent: Imagine model patient and proxy consent like those W3C Verifiable Credentials you hear about. We're just keeping track of the credential's hash and whether it's been revoked on the blockchain. This way, we can conveniently display those Verifiable Credentials during API calls, like when we're using TEFCA Individual Access Services. It really helps us minimize the movement of Protected Health Information (PHI)! Take a look at this link: w3.org. You might find it interesting!
Clinical trials: It’s really cool to see how Mayo Clinic and its partners have come together! They’re using blockchain technology to streamline the eConsent process, keep track of documents, and monitor everything. The best part? They manage to do all this while ensuring a secure, tamper-proof record without having to centralize all the raw data. Pretty innovative, right? Want to dive deeper into it? Check it out here: pharmafocus.com.
Privacy tech roadmap: As we look to the future, it’s a good idea to combine Trusted Execution Environments (TEEs)--like Google Confidential Space--with Intel's TDX GA, which is expected to roll out in 2025. This way, we can ensure secure computing for all that sensitive information we handle. And hey, let’s not forget to keep tabs on zero-knowledge and federated approaches as they get better for healthcare applications. If you want to dive deeper into it, feel free to check this out: (docs.cloud.google.com). It’s a great resource!

Architecture patterns that work in healthcare (no code required)

1) Hybrid Ledger (the go-to option)

What: So, we’re storing Protected Health Information (PHI) in Electronic Health Records (EHRs) and other data places like FHIR servers, S3/Blob, and databases. We're just sticking to the basics here--keeping it super simple by jotting down essential stuff like hashes, timestamps, signers, and references in a permissioned ledger. Nothing too detailed or identifying, just what we need!
Why: This method checks off HIPAA’s data minimization rules, and it also aligns with the "right to be forgotten" off-chain. It still keeps a solid audit trail that the Office for Civil Rights (OCR) and insurance companies can rely on. Hey, don’t forget to take a look at Fabric v2! You won’t want to miss it! 5 has rolled out this cool new feature that lets you wipe out your private data while still keeping the hash stored on-chain. This is super handy for sticking to those retention policies! If you're curious to dive deeper into that topic, just check it out here. There's a lot of great info waiting for you!

2) Attested Integrity Ledger

So, here’s the scoop: we’re discussing this cool managed and super secure ledger that’s backed by TEE. It’s specifically set up for managing audit receipts. Pretty neat, right? This is especially useful for TEFCA/FHIR gateways. It really helps with keeping tabs on consent proofs and making decisions about prior authorizations.

Why it’s great: What’s awesome about this setup? You get cryptographic receipts that make everything super easy to manage, plus it doesn’t take up much space. And the best part? It usually costs about $3 a day for each instance, as of March 1, 2025. For more info, feel free to take a look here.

3) Consortium Orchestration Layer

What: Think of this as a multiparty framework, kind of like Hyperledger FireFly. It’s designed to make it easier for different organizations to manage their data flows. It combines off-chain info with on-chain states, and hey, if you want to use tokens, that’s totally your call!
Why: It has some really useful features, like messaging built right in, easy identity management, and it can handle multiple chains. This makes it a great choice for businesses looking to set up efficiently. Plus, it's already been tried and tested in healthcare groups! Take a look at this link: (hyperledger.github.io). You'll find some really interesting stuff there!

4) TEFCA-Aligned Security and Identity

What: So, we’re planning to use UDAP/FAST Security for handling authentication and authorization with FHIR, all in line with the timelines outlined in the Facilitated FHIR SOP. Also, we’ve got to ensure that our identity assurance is in sync with IDIAL1. 8/AAL2.
Why: This strategy gets you ready for TEFCA FHIR by 2026 and helps ease the hassle of those annoying point-to-point agreements. For more info, feel free to check it out here!

Tooling choices in 2025 (practical options)

Handled Fabric Networks (AWS AMB, Fabric 2). 2 LTS): These networks really help simplify things when it comes to infrastructure. Plus, they work effortlessly with VPC, KMS, and your company’s IAM. It’s all about making life easier, right? They're just great for managing all your DSCSA, PA, and Directory stuff! Check it out here.
Confidential Ledgers (Azure): With TEE-backed WORM receipts, Azure makes it super easy to handle consent and audits without having to set up a whole consortium chain. Isn’t that cool? If you want to dive deeper, check it out here.
Confidential Compute (Google Confidential Space): This cool solution supports verified workloads across different clouds, and it allows multiple parties to process data together--all while keeping the risk of data exposure super low. If you’re curious and want to explore more, check out the details right here. Happy reading!

Sure thing! Here’s a more laid-back version of your text:

**Orchestration (Hyperledger FireFly 1.

Just a heads up, I've been trained on information up until October 2023. 3/1. FireFly combines off-chain data with on-chain proofs, plus it offers token APIs and multi-chain connectors. It's a pretty cool way to bridge the gap between different types of data and blockchain technology! It's already starting to make some serious waves in the healthcare world! Hey! If you want to see the latest updates, just click here. You'll find all the fresh info waiting for you!

Here's a handy tip: when you're putting together your "trust layer," try to stick with open standards and managed services. It's a smart move! Make sure to stick with those systems you've already certified, like your EHRs and data lakes, for keeping your PHI safe. That way, you can skip the headache of re-auditing your entire stack.

Security, privacy, and audit: what the board will ask

HIPAA Security Rule 164. 312(b): It's super important to lay out exactly how you keep tabs on and assess activities involving ePHI. Just a quick reminder to ensure your setup includes some key elements: make sure you've got unchangeable event records, clearly defined user identities, reasons for access, and solid evidence of consent references. These components are super important! If you want to dive into more details, just click here. Happy exploring!
Part 2 (Substance Use Disorder): Make sure your consent processes are all set by the compliance deadline on February 16, 2026. You can use VCs to easily manage and update consents for Treatment, Payment, and Operations (TPO). They're super handy because you can streamline the whole process and revoke permissions whenever you need to. Quick reminder: make sure your chain doesn’t hold on to any Part 2 info. If you’re looking for more details, check out this link. It’s got all the info you need!
Zero Trust: It's all about securing your systems and reducing the risk if something does go wrong. You can achieve this by using micro-segmented service meshes. Think of it as creating a secure bubble for each organization, where each node has its own unique identity. Plus, adding temporary credentials helps keep things fresh and secure, and don’t forget to focus on ongoing authorization to maintain that security over time. If you're looking for more info, you can check it out here.
Breach posture: Make sure to pair those permanent logs with fast, easy-to-use exports for regulators. This method not only helps you respond to incidents faster, but it also demonstrates that you're doing the right thing--especially given the rising number of healthcare breaches these days. If you want to dive deeper into this topic, check out this site for more info!

Budgeting and timelines: what’s realistic

Discovery + Proof of Concept (8-12 weeks, one use case, 2-3 organizations): We’re estimating a budget in the ballpark of $150k to $400k. This includes everything from setting up security architecture to integrating a FHIR gateway and offering immutable audit receipts. Alright, so here’s the scoop: once you transition from the pilot phase to limited production--which usually takes about 6 to 9 months--you're looking at working with around 5 to 7 different organizations. Just a heads-up, you’ll probably need to set aside roughly $750k to $1 million for this stage. 5M** for this phase. This total also reflects a boost in identity assurance, which you can think of as IDIAL1. You’re all set with training on data up to October 2023! So, let's talk about a few things we need to tackle: we’ve got the 8/AAL2 stuff to handle, making sure we’re on top of UDAP security, and of course, we need to get those TEFCA-ready endpoints up and running. Let’s dive into it!
Scale-Out (10+ organizations, multi-state): In your first year, you can expect to see around $2M to $6M. We can really cut down on operating costs by using managed ledger services and taking advantage of the FHIR servers we already have.

The numbers might vary based on the vendor’s daily rates and the compliance scope you're dealing with--whether that's just HIPAA or something broader like Part 2. That said, it’s super important to kick things off by asking for ROI telemetry right away. Take a look at the KPIs below for more details!

KPIs that prove ROI (and survive audits)

Provider directories: We're keeping an eye on how many directory records we verify each quarter. Our goal? To reduce those pesky duplicate outreach efforts and track how long it's been since the last time we verified everything. So, what's our aim? We're looking to cut down our outreach by about 30-50% in the next six months. (synaptichealthalliance.com).
Prior authorization: We're diving into a few key stats here: we're checking out how long it takes to make decisions, the percentage of straight-through processing (STP), and we'll also take a look at appeal rates and denial overturn rates. These benchmarks are connected to CMS APIs and some metrics templates. (cms.gov).
DSCSA: So, over here, we're looking at a few key things: we're checking out what percentage of transactions actually come with valid receipts, how long it takes to sort out any issues that pop up, and whether our reports for regulators have all the info they need.
Security/audit: So, here's what we're looking into: we're keeping an eye on the percentage of data-touch events that come with immutable receipts. We're also tracking how long it takes on average to dig into PHI access issues, and we’re curious about how many endpoints are currently under UDAP authorization as we wrap up Q4 2025. (blog.hl7.org).

Buyer’s checklist: RFP questions that separate signal from noise

Standards and Interoperability

Supported FHIR Versions/IGs: Curious about the FHIR versions and implementation guides (IGs) we’re currently backing? You can find some pretty convincing evidence of our Bulk Data v3 readiness, plus how we fit in with Da Vinci's CRD, DTR, and PAS by just clicking this link: Bulk Data v3 Evidence. It’s worth a look!
TEFCA Compliance: As we gear up for TEFCA, what’s our game plan for meeting the Facilitated FHIR SOP and UDAP Security requirements by January 1, 2026? It’s definitely worth checking out all the details here: TEFCA and HTI Security Requirements. Don't miss out--knowing what's ahead can really help us stay on top of things!

Then, we’ll look at what you’ll have hanging out in your Virtual Private Cloud (VPC). Oh, and make sure you include some proof of High Availability (H/A) and Disaster Recovery (DR) too! It's super important to have that covered. For more details, feel free to check this out: aws.amazon.com. You might find just what you’re looking for!
Identity Assurance: What’s the best way to pin down IDIAL1? Hey, quick question: Is the 8+/AAL2 setup good for both people and apps? Also, what kind of backup plans do you have in case something goes wrong? If you’re looking for more details, check this out: build.fhir.org.

Business

We're putting together an ROI model that takes into account our baseline metrics and shows how expanding our member base could really shake things up (you know, that classic network effect at play). When it comes to our exit plan, we're really zeroing in on data portability. Basically, we want to make it easy for you to export things like receipts, proof, and mappings. We've got a plan for winding down the network without compromising our audit integrity. It's all about making sure we can transition smoothly while still keeping everything above board.

When it comes to things like e-consents, clinical privileges, and workforce credentials, it's a good idea to stick to verifiable credentials. They really help ensure everything is legit! Just remember to keep all the non-identifiable proofs on-chain. It's super important! This doesn't just give a boost to the TEFCA IAS; it also helps keep that annoying PHI sprawl under control. (w3.org).

Sticking to TEE-backed audit ledgers is a smart move! They help keep everything secure without adding too much extra work on your plate. Just a friendly reminder: make sure to keep your PHI off-chain! You can check out more about it here.

Hey, just a heads up! It’s a good idea to touch base with UDAP/FAST Security pretty quickly. That way, you won’t find yourself scrambling to redo your authorization in 2026. Better to be proactive, right? (blog.hl7.org).

Hey there! Just a quick tip for you: when you're working with the data lifecycle, make sure you're thinking ahead. If you're using Fabric's PurgePrivateData() for your private collections, that's great! But remember to keep that on-chain evidence safe and sound. You don’t want to lose any important info! Don’t forget to have your document retention and purge procedures sorted out! It’s super important to keep everything organized and know when it’s time to toss old files. (hyperledger-fabric.readthedocs.io).

Begin keeping an eye on those KPIs right from the start, and make sure you’ve got the exports ready for regulators as soon as day one rolls around. It'll definitely make your life easier when OCR or OIG comes around looking for answers. (hhs.gov).

Common pitfalls to avoid

Storing PHI directly on the blockchain can really complicate things, especially when it comes to sticking to HIPAA/Part 2 regulations and respecting the rights of the individuals whose data we're dealing with. Instead, it’s probably a good idea to embrace hybrid patterns. (hhs.gov).

Hey, have you thought about just going with the VCs, UDAP, and FHIR standards that your partners are already using instead of making your own custom cryptography? That way, you can avoid a bunch of unnecessary headaches! (w3.org).

Hey, don't forget about identity assurance! If you're not careful with your identity verification, it can totally throw off the whole provenance process. Hey there! It’s time to get on board with IDIAL1! We've got an 8+ rating for patients and an AAL2+ for the workforce, just so you know--it's the current situation. (build.fhir.org).
Delaying security architecture is definitely not the best approach. Really, getting on board with Zero Trust Architecture (ZTA) principles--like having short-lived credentials, keeping up with continuous authorization, and using micro-segmentation--should be at the top of your priority list. It isn’t just an afterthought; it’s something you want to bake into your approach from the get-go. (csrc.nist.gov).

Your first 90 days (practical action plan)

Dealing with a Business Challenge with Some Help from Regulations: Alright, so here's the deal: you gotta choose one of these options--it's either the provider directories (think Synaptic style), the prior authorization decision-making stuff (that’s CMS-0057-F), or the DSCSA verifications. What are you feeling? (synaptichealthalliance.com).
Establishing Standards and Security Guidelines: Alright, let’s tackle getting those FHIR Implementation Guides organized. We should also draft a roadmap for UDAP/FAST with a goal to have everything lined up by January 1, 2026. Plus, we need to set some clear identity assurance targets--time to get started on IDIAL! 8/AAL2). (blog.hl7.org).
Architecture Proof of Concept (8-12 weeks):

This phase usually takes about 8 to 12 weeks. During this time, we’ll dive into creating a proof of concept for the architecture. It’s all about testing ideas and making sure everything works as we envision it. We’ll explore different options and fine-tune our approach to set a solid foundation for the project. It's an exciting time to get creative and see what’s possible!

Set up a private ledger or a managed Fabric network, and connect it to your FHIR server. Don’t forget to note down those event receipts--just make sure there’s no PHI included! Hey, just a quick reminder to whip up some sample audit exports for the OCR when you get a chance. (azure.microsoft.com).

Governance and Return on Investment: Alright, so here’s the plan: we need to create some rules for our consortium. This involves figuring out the data model, how we’ll handle any disputes, and what the onboarding process will look like. We should also set some basic Key Performance Indicators (KPIs) to measure our success. Plus, let’s take a shot at predicting the potential savings we could see in operations and any risks we might lower in terms of compliance.
Scaling Up: Alright, so here's the deal: you're going to put together onboarding playbooks for more than five external partners. It’s important to map out those TEFCA alignment steps and figure out how the QHIN integration strategy might come into play--just make sure you're clear on who your QHIN(s) are! (sequoiaproject.org).

Final thought

Blockchain in healthcare may not be the perfect fix, but by 2025, it’s definitely on track to become a reliable way to exchange information while keeping sensitive data safe and sound. If you store your Protected Health Information (PHI) off-chain, it's a smart move to leverage TEFCA, FHIR, and UDAP. Plus, make sure your design is super compliant with HIPAA and Part 2 for that all-important auditability. Not only will you save some cash and minimize risks right now, but you’ll also put yourself in a great position for 2026!

Hey there! Are you on the hunt for a 2-hour workshop that dives deep into your unique tech stack? Whether you’re into FHIR servers, payer platforms, ERP/WMS, or identity solutions, 7Block Labs is here to help! We'll collaborate to find that ideal first use case, map out the architecture, and pin down some solid KPIs. Let’s get started on this journey together! On top of that, you'll leave with a solid 90-day plan that’ll help you kick things off the right way.
