The 2025 reality check: what “pilot-ready” actually means

“Pilot-ready” in U.S. These days, when we talk about healthcare, it really revolves around a few main ideas:

You really should dive into FHIR R4 APIs, especially if you're familiar with the SMART v2 path. It's the way to go! So, here’s the scoop: certified health IT is making a move to the USCDI v3 along with FHIR US Core 6. Exciting times ahead for the industry!

1. By January 1, 2026, you'll find it's all set at 0. So, teams have until March 1, 2026, to sort things out with enforcement discretion, but the main aim is still clear. Don't forget to incorporate these baselines into your pilot! It's super important to have them in place. (healthit.gov).

Hey there! Just a heads-up about CMS-0057-F. The payers that are impacted by this need to get going on implementing FHIR Patient Access, Provider Access, Payer-to-Payer, and a Prior Authorization API. It's important stuff to stay on top of! So, it looks like most of the compliance deadlines are aimed for January 1, 2027. But keep in mind, some of the operational stuff is actually kicking off in 2026. It's definitely a smart idea for your pilot to take advantage of the Da Vinci and CARIN IGs that CMS is suggesting. (cms.gov).

TEFCA is officially up and running! It’s got a whole lineup of designated QHINs, including eHealth Exchange, Epic Nexus, Health Gorilla, KONZA, and MedAllies. Exciting times ahead! Make sure to watch for new players like CommonWell, Kno2, eClinicalWorks, and Surescripts making their way in 2025. It'll be interesting to see how they shake things up! Make sure your pilot is set up to handle TEFCA traffic. Also, it's a good idea to gear up for the FHIR and FAST UDAP security requirements that are coming into play on January 1, 2026. It’s better to be ready ahead of time! (rce.sequoiaproject.org).

Just a quick heads-up! When it comes to information blocking penalties, things are getting serious. Since September 1, 2023, developers, HIEs, and HINs could be looking at fines as hefty as $1 million for each violation. So, definitely something to keep in mind! Hey, just a heads-up! Make sure your smart contracts and APIs are running smoothly so they don’t cause any hiccups for EHI. You don’t want any roadblocks to pop up! (oig-kan-dns1.oig.hhs.gov).

Use cases that show ROI in 90 days

Think about those complicated workflows that involve a bunch of different parties. In these situations, having a reliable, unchangeable source of truth, along with a way to verify identities, can really speed things up and cut down on the amount of rework. It makes a huge difference!

• Keeping the provider directory accurate with payer-provider info using crypto attestation and audits: The team over at Synaptic Health Alliance has really hit the mark on this one. They've demonstrated some seriously impressive returns in their production runs--one of their participants even saw a jaw-dropping 500% ROI! For sure, this is a model your pilot could totally use on permissioned chains. Take a look at them here: synaptichealthalliance.com. You'll find some really interesting stuff!
• Prior authorization orchestration: This is really about blending the Da Vinci CRD/DTR/PAS with a ledger that tracks all the request and response proofs, as well as the versions of the rules. Oh, and by the way, now’s a great time to start getting ready for the CMS “Electronic Prior Authorization” reporting that’s scheduled to roll out by 2027. If you want to dive deeper into the details, check this out: (cms.gov). You’ll find all the info you need!
• Credentialing and Privileges: So, you’ve got the ability to hand out W3C Verifiable Credentials (VC 2.0). You can check up on healthcare providers' licenses and privileges as needed, and you don't have to keep making constant phone calls to do it. Hey, just a quick heads-up about VC 2! So, back in May 2025, 0 officially got the stamp of approval as a W3C Recommendation. If you're curious and want to dive deeper, just check this out: (w3.org).
• Track-and-trace like DSCSA in clinical logistics: We're diving into some cool stuff like privacy-preserving proofs that help us keep tabs on ownership, temperature, and chain-of-custody. The FDA has been running some pilot programs that really show how blockchain can fit into the DSCSA framework. Plus, they’re looking into using zero-knowledge (ZK) techniques to keep business data secure, which is pretty cool! Want to dive deeper? Check it out here: fda.gov.

Architecture decisions that survive scrutiny

• Make sure to keep that PHI (Protected Health Information) off the chain. How about we keep it simple and just store hashes, pointers, event attestations, and credential statuses right on the chain? Just a quick reminder: when you're handling clinical data, make sure it's stored in those HIPAA-compliant places that have a Business Associate Agreement (BAA) set up. You know, like AWS, Azure, or Google Cloud Platform. It's super important! Whenever you get the chance, it’s a good idea to use de-identification methods such as Safe Harbor or Expert Determination. They really help protect people's privacy! If you want to dive deeper into this topic, check out hhs.gov. They've got a ton of great info waiting for you!
• Identity and authorization: If you're diving into external-facing APIs, check out SMART on FHIR and also look into UDAP/FAST Security. They’re pretty solid resources! Hey there! Just wanted to give you a quick heads-up. The TEFCA’s Facilitated FHIR SOP is asking for the FAST UDAP Security IG to be set up by January 1, 2026. But if you’re looking to get a jump on things, it’s a great idea to start supporting SMART and make that switch now! If you want to dive deeper into this topic, head over to blog.hl7.org. You'll find some really interesting insights there! If you're thinking about your team and the B2B apps you use, it might be a good idea to check out UDAP client credentials and organization-bound trust. It's something worth considering! If you want more info, just check out build.fhir.org. It’s a great resource!
• Let’s chat about verifiable credentials for both providers and patients. Have you heard about DIDs, or Decentralized Identifiers? They’re officially recognized as a W3C standard now! The newest version is VC 2. So, you've got some pretty neat updates that boost data integrity and introduce handy options like JOSE/COSE for secure status lists. This is just what you need for managing suspended credentials! If you're looking for more details, check out w3.org. They’ve got a ton of great info there!
• Network choice: If you’re looking for a solution that handles permissioning and private data collections, Hyperledger Fabric could be a great fit. It’s particularly useful when you’re working with known parties that have established governance structures. Hey, if you’re considering going with Enterprise Ethereum--like Besu for private transactions or Tessera--then you’re definitely onto something! It’s a solid choice, especially when you start thinking about EVM programmability, layer 2 rollups, or even those exciting on-chain ZK proofs down the line. If your business needs point-to-point privacy and you’re dealing with bilateral flows, Corda is definitely a strong choice. If you're not quite ready to dive into running a consortium just yet, you might want to check out some managed "confidential ledger" solutions. One good example is Azure Confidential Ledger. It's designed to make things easier for you by providing tamper-evidence with Trusted Execution Environments (TEEs). It could really simplify the whole process! Hey, take a look at this link: azure.microsoft.com. It’s worth checking out!
• Crypto Agility and PQC: First things first, take stock of all your crypto assets. It's a good idea to map out a plan for a hybrid migration while you’re at it. Just a heads up--NIST is set to wrap up the final versions of PQC FIPS 203 (ML-KEM), 204 (ML-DSA), and 205 (SLH-DSA) in 2024. So as you're getting ready to rotate your keys, it's a good idea to think about how you'll support hybrid TLS and signatures moving forward. If you want all the details, check out nist.gov. It’s got everything you need!

The 90-day plan (week-by-week)

Weeks 1-2: Scope, compliance gating, and measurable outcomes

• Figuring out the problem and setting those key performance indicators (KPIs). Pick one key performance indicator (KPI) that you can really impact over the next three months. For example, you could aim to reduce the turnaround time for PA decisions by 30% or cut the time it takes to update the provider directory by 50%.
• Regulatory alignment checklist First things first, take a moment to identify your key players and see how they fit into the HIPAA roles. Are they a covered entity or a business associate? Once you've got that sorted, make sure to keep an eye on how the data flows between them. Take a moment to see if getting involved with TEFCA matters to you--whether that's directly or by teaming up with a QHIN partner. Make a quick list of QHINs that work well for your area and align with your onboarding timeline. (rce.sequoiaproject.org). Hey there! If you're dealing with payers, just a heads up to get cozy with the CMS-0057-F APIs and the recommended implementation guides, such as CARIN BB, PDex, CRD/DTR/PAS, and others. Keeping everything aligned will definitely make your life a bit easier! Make sure you hit those API requirements by January 1, 2027, but it’s a good idea to start sketching out your designs now. (cms.gov). Make sure to take a moment and double-check that your design makes it super easy to access electronic health information (EHI). You definitely want to steer clear of any pesky information blocking issues! (oig-kan-dns1.oig.hhs.gov).
• Data strategy Start by figuring out the absolute essentials for your on-chain presence. This means focusing on things like hashes, timestamps, and statuses. And remember, it’s best to leave any personal health information (PHI) off the blockchain entirely! If you're working with de-identified data, just remember to keep track of whether you're following the Safe Harbor method or going with Expert Determination. It's important to have that documentation in place! If you decide to take the Expert route, make sure to keep a copy of the expert’s documentation handy. (hhs.gov).
• Security baseline Hey there! It’s time to start thinking about your SMART/UDAP strategy and getting your FAST Security plan set up for TEFCA. Make sure you have everything ready to roll by January 1, 2026. You've got this! (blog.hl7.org).
• Kick off your HIPAA Security Risk Analysis (SRA) and make sure to jot down the “recognized security practices” you plan to implement. The Office for Civil Rights (OCR) really looks at these when they’re enforcing the rules, so it’s a good idea to keep track! (hhs.gov).
• Cloud and BAAs So, when you’re picking services that meet HIPAA requirements, think about options like AWS, GCP, or Azure. Just remember to get those Business Associate Agreements (BAAs) signed and taken care of! It’s a super important step to keep everything compliant and secure. Alright, let's get your VPC or VNet up and running, set up those KMS or HSM services, manage your secrets, and create some solid audit trails. It’s all about keeping things organized and secure! (aws.amazon.com).

Deliverables:

• Problem Statement
• KPI Targets
• Compliance Matrix
• High-Level Architecture
• Risk Register
• Setting up a Cloud Landing Zone with a Business Associate Agreement (BAA).

Weeks 3-4: Detailed solution architecture and governance

• Mapping out data models and FHIR. Alright, let’s kick things off! Start by deciding which FHIR resources you want to dive into first. You might want to look at the Practitioner, Endpoint, or Organization resources if you're focusing on directories. And if prior authorization is your thing, then Coverage or PA could be the way to go. It's really crucial to stay on top of US Core version 6.

1. 0. (healthit.gov).

• Identity and trust Hey, let's get rolling on those DID and VC schemas for the provider credentials. We’re talking about stuff like licenses, NPI numbers, and any privileges they might have. Go ahead and start drafting! Hey, just a heads-up! Make sure to put together a game plan for the revocation and status lists under VC 2. It’s super important!

0. (w3.org).

• Ledger and privacy design are both pretty important topics. Alright, so now it's decision time! Are you thinking about going with Fabric, Besu, Corda, or maybe Confidential Ledger? You’ll definitely want to figure out your channels and collections. And if you're planning on doing any private transactions, that's worth considering too! Alright, here’s the deal: let's break down what gets hashed, who has access to it, and how long we keep things around. (azure.microsoft.com).
• TEFCA approach Hey there! If you’re looking to get started, why not reach out to a QHIN? They can help you with some sandbox onboarding. It’s a great way to dive in! Don’t forget to note down their connectivity, directory, and policy requirements. You’ll want to make sure these line up with what you need for your pilot data project! (rce.sequoiaproject.org).
• Just a heads up about prior authorization, if it’s relevant for your situation.
• Make sure you’re aligned with CMS-0057-F by using the Da Vinci CRD/DTR/PAS. Let's also plan to showcase the key metrics we need to focus on. Hey, just a quick reminder to take another look at the timeline details. So, we’re looking at 2026 for operations, then moving on to APIs in 2027, and don’t forget about the MIPS attestation happening in 2027 as well. Thanks! (cms.gov).

Deliverables

• Solution design document
• Data dictionary
• Sequence diagrams
• Governance charter (you know, the one that lays out who’s involved, what data rights everyone has, and the service level agreements).
• Here are some drafts for the VC schema.

Weeks 5-6: Build the rails

• Get your network going. Alright, let’s get those nodes prepped, shall we? Aim for about 3 to 5 organizations. Don’t forget to set up your Certificate Authority (CA) and lay down some strong policies while you’re at it! Make sure you’re automating things with Infrastructure as Code (IaC). It really helps streamline everything! Oh, and don’t forget to get that block explorer up and running! And make sure to set those audit views too--just in read-only mode, of course!
• Keeping things secure and following the rules. Just a quick reminder to make sure you’re enforcing mTLS, validating those JWTs, and setting up ABAC using UDAP scopes. It’s all super important for keeping everything secure! Make sure to switch up your keys every now and then and use secrets backed by KMS. It'll keep your security game strong! Oh, and don't forget to log all the access and admin actions! That way, you'll have a nice, clear trail to follow.
• FHIR connectors
• Build adapters for EHR sandboxes, specifically for R4 format.

0.

1. Let’s work on the TEFCA and Participant endpoints too, and don’t forget to roll out the SMART App Launch v2 flows when it feels appropriate. For more info on this, take a look at the article over at healthcareitnews.com. It's got all the details you need!

• VC/identity Let's get started on issuing and verifying one type of credential, like the provider directory attestation. It’s a good way to kick things off! Just a heads-up: remember to keep the status stored on-chain, but make sure to keep any personal identifiable information (PII) off-chain. If you want to dive deeper into this topic, check out w3.org. There’s a bunch of great info waiting for you there!
• Testing data and creating synthetic datasets.
• When you're testing locally, go ahead and use synthetic FHIR bundles. Just make sure to steer clear of any PHI in your development environment! If you need some guidelines, check out the info on hhs.gov. It’s a solid resource!

Deliverables:

• We're working on getting a network up and running.
• The FHIR APIs are all ready to go!
• We've got a Proof of Concept ready for VC issuance.
• We’ve got some basic dashboards all set up and ready for you!

Weeks 7-8: Integrations, scenarios, and ZK options

• End-to-End Scenarios
• Provider Directory: First up, we kick things off with a proposed change. After that, it goes through a peer review process. Once that's wrapped up, it gets the thumbs up with on-chain attestation. Great news! The off-chain directory has finally been updated, and those changes are now being shared through FHIR Endpoint and Organization updates, along with notifications.
• Prior Authorization: It all starts with the CRD hook in the EHR, and then you move on to filling out those DTR questionnaires. Once that's done, we go ahead and submit the PAS. You'll be able to check out the timestamps for the ledger anchors’ requests and responses, plus the policy references too.
• Zero-Knowledge and Selective Disclosure (Optional, Super Valuable). We're considering trying out a new way to share some key details about VC attributes. For example, we could confirm that a license is still valid without having to re-share the entire credential each time. Sounds pretty efficient, right? There's a roadmap in place for upcoming ZK policy proofs, too. (w3.org).
• Patterns Inspired by DSCSA (Optional for Life Sciences). We're excited to highlight some cool privacy-friendly ownership transfers for samples or devices, drawing inspiration from the awesome stuff happening in FDA pilot projects. (fda.gov).
• TEFCA Dry Run
• We're diving into how to validate patient discovery and retrieve records in a QHIN test setting, especially when it comes to treatment. We're going to keep an eye on how things are running and keep track of any error codes that pop up. (rce.sequoiaproject.org).

Deliverables

• Demo scripts
• Scenario runs
• Test logs
• Performance baseline

Weeks 9-10: Security hardening and compliance proofs

• HIPAA Security Risk Assessment and Fixes. Hey, don't forget to note down any risks you come across. It’s a good idea to put some fixes in place too--like setting up multi-factor authentication for admin accounts, encrypting any data you have stored, and following the least privilege principle. These steps can really help keep things secure!
• Information blocking cross-check Make sure you take a moment to confirm that your ledger and APIs aren’t shutting out access to electronic health info, unless it’s absolutely necessary. You might also want to think about creating a simple internal process for proofing things on request. If you're looking for more info, you can dive into the details right here: oig-kan-dns1.oig.hhs.gov. Happy exploring!
• PQC readiness Make sure to carve out some time to put together a solid list of your cryptographic tools and develop a step-by-step plan for transitioning to NIST's Post-Quantum Cryptography (PQC) standards, like ML-KEM, ML-DSA, and SLH-DSA. It's a good move to tackle this gradually! Make sure to take a moment to check how your crypto-agility is doing in your CI/CD process! If you’re looking for more details, you can check it out here: nist.gov. It’s got all the info you’ll need!
• Understanding your privacy in reproductive health (if relevant).
• Take a moment to check out your workflows that involve PHI, especially with the new changes on the horizon from the 2024 HIPAA Privacy Rule. Don’t forget to think about how these updates could lead to potential legal issues down the line in 2025! Make sure to update your notices and any attestations when necessary! If you’re looking for more details, check this out: hhs.gov. It's a great resource!

Deliverables:

• SRA report
• Security control matrix
• Crypto-inventory
• We’ve updated the privacy notices where necessary.

Weeks 11-12: Pilot launch, telemetry, and go/no-go

• Pilot Cohort Onboarding We're thinking about bringing in 2 or 3 organizations--like maybe one payer, one provider, and one intermediary. Ideally, they'd all be set to go with signed Business Associate Agreements (BAAs) and data-use agreements in place.
• Observability and KPIs How about we set up some dashboards? It’ll help us keep an eye on things like cycle time, error rates, rework, and those audit trail queries. Hey PA pilots! Just a quick reminder that it’s really important to begin keeping an eye on the metrics that CMS is looking to have reported publicly.
  If you want to dive deeper into the details, just head over here: cms.gov.
• Executive Demo and What’s Next. Alright, so here’s what we’re going to do: we’ll kick things off by showcasing some before and after metrics. Then, we’ll dive into a six-month scaling plan that covers a few key areas. First up is getting that QHIN production connectivity sorted. After that, we’ll focus on broadening our credential network, and finally, we’ll make sure we’ve got those payer API certifications all lined up. Exciting stuff ahead!

Deliverables

• Pilot: Kick things off with a pilot program on a smaller scale.
• Executive Readout: Put together a summary for the execs.
• Build a Backlog for Scaling: Let’s put together a backlog that will help us scale the project effectively.

Implementation details we’ve found decisive

• Consent and authorization If you want to get patient-controlled sharing up and running smoothly, try combining SMART on FHIR with UDAP registration. It's a solid approach! It's a smart move to let app revocation happen within an hour. This way, you’ll be keeping up with the HTI-1 standards for certified modules, and that’s definitely a plus! If you want to dive deeper into the details, just click here. Happy reading!
• Minimal on-chain payloads Let’s keep it straightforward. Just make sure your attestations are concise and include the essentials: what changed, who signed off on it, when it happened, and which policy or version it relates to. And don’t forget to add a URI that links to the off-chain FHIR or document storage! This method not only keeps your ledgers nice and lightweight, but it also reduces the risk of security breaches. Plus, it makes it way easier for users to access and export their data whenever they need to.
• Let's make sure we're aligning with TEFCA, but we don’t want to bite off more than we can chew. If getting onboarded directly with a QHIN isn’t in the cards for you in the next 90 days, think about connecting through the gateway of a QHIN participant instead. It could be a good workaround! Don't forget to double-check your FHIR setup and UDAP security! It's super important to make sure everything's in good shape as we gear up for those upgrades in 2026. If you're looking for more details, just check this out here. It's got everything you need!
• Vendor/EHR interoperability Make sure you're focusing on building with the US Core and Da Vinci/CARIN IGs CMS lists.
  By taking this approach, you'll save yourself a ton of hassle later on. Plus, when it comes to those compliance audits in 2026-2027, you’ll make them feel like a walk in the park! Learn more here.
• Information blocking guardrails
• Set up a “break-glass” option and jot down your reasons for using it, following ONC-aligned exceptions. By automating the process of gathering evidence, your legal and compliance teams can jump on any inquiries much faster. This means they can tackle any challenges that come their way without missing a beat. Hey! If you're interested, you can find all the details right here. Take a look!
• Post-quantum crypto agility Hey there! When you're running your pilot, it’s not enough to just flip the switch on PQC. Instead, take some time to really think about how you set up your keystore and key labels. If you do it right, you'll have a smoother transition from ECDSA or EdDSA to ML-DSA or hybrid models down the line, all without having to go back and overhaul your contracts or credentials. Trust me, a bit of planning now will save you a lot of headaches later! If you want to dive deeper into this topic, check out this link. It's got all the details you need!

Example pilot blueprints

1) Provider Directory Quality Network (Payer + Provider + Intermediary)

• Goal: We're looking to reduce undeliverable mail and claims edits by 30% within the next 90 days.
• Flow: Alright, so here's the deal: providers will throw out some suggestions to tweak their profiles. Then, the payers take a look at what’s been changed. Once everything's been double-checked and verified, we go ahead and lock those updates right onto the blockchain. Pretty straightforward, right? After that, a sync job jumps in to handle the updates for the payer and provider FHIR endpoints.
• Why It Works: This method helps everyone get on the same page and keeps a record of everything that's happened. On top of that, the Synaptic Health Alliance has been doing really well when it comes to returns on investment. Take a look at this: (synaptichealthalliance.com). You might find something interesting!

2) Prior Authorization Fast Lane (Payer + Two Provider Sites)

• Goal: We're looking to cut down the median time it takes to get a prior authorization decision from 10 days to just 3 days.
• Flow: So, here’s the deal: when the Electronic Health Record (EHR) sets off a Clinical Reasoning Decision (CRD), that’s when the Digital Transformation Resource (DTR) jumps in to handle all the documentation. Pretty seamless, right? After that, the Prior Authorization System (PAS) takes care of sending everything through. On top of that, the ledger tracks every step of the journey and notes down the policy artifact ID that was used to make those decisions. No need to stress -- we’ve got all our metrics lined up perfectly with the CMS reporting templates! Check it out here!.

3) Provider Credential VC Network

• Goal: Make it super easy to issue or check licenses and privileges in less than a second whenever we're scheduling or making referrals.
• Flow: So, the health system kicks things off by creating a VC 2. They put out status lists, and then the verifiers come in to check the signatures and statuses. What's really neat is that only the hashed references and statuses are stored directly on the blockchain. For more info, take a look at w3.org! It's got all the details you need.

Compliance cliff notes for decision-makers

• HIPAA: Remember to keep your personal health information (PHI) off the blockchain. It's also really important to have those Business Associate Agreements (BAAs) in place. Don't forget to carry out and keep a record of your Security Risk Assessment (SRA). And if you ever need to move any data, make sure you're extra careful about de-identifying it! (hhs.gov).
• ONC HTI-1: Buckle up! We’re diving into USCDI v3, SMART v2, and US Core 6. Exciting times ahead!

1. You've got until January 1, 2026, to get it done, but don't stress too much--there's a bit of wiggle room until March 1, 2026. (healthit.gov).

• TEFCA: You’ll need to choose whether to go with a specific QHIN or just be a participant. And by the way, get ready to tackle FAST UDAP security by January 1, 2026! Right now, they're testing out Stage 3 QHIN-to-QHIN FHIR. (blog.hl7.org).
• CMS-0057-F: Make sure your APIs for Patient/Provider Access, P2P, and Prior Authorization are all set to go by January 1, 2027. But hey, don’t wait until then--some operational improvements are coming even earlier! The baseline incorporates FHIR R4.

0.

1. So, we have US Core, SMART, Bulk Data, and OpenID Connect on the table. (cms.gov).

• Information Blocking: Make sure you avoid anything that could hinder access to Electronic Health Information (EHI). Getting caught can lead to some serious penalties--like up to $1 million for each violation! This rule applies to developers as well as Health Information Exchanges (HIEs) and Health Information Networks (HINs). So, it's definitely something to keep in mind! (oig-kan-dns1.oig.hhs.gov).
• Reproductive Health PHI: So, here’s the deal--there’s a new rule coming in 2024 that’s shaking things up a bit with the HIPAA Privacy Rule, especially as we gear up for the legal changes that are hitting in 2025. It’s a good idea to get your legal teams on board to review any data that might be impacted and to check out the attestation requirements too. Just a smart move to stay ahead of the game! (hhs.gov).
• PQC: So, guess what? NIST just launched the first PQC standards (ML-KEM, ML-DSA, SLH-DSA) in 2024! If you haven’t started thinking about your migration plan yet, now's definitely the time to get the ball rolling. (nist.gov).

Budget and timeline signals (what we see across pilots)

So, if you're looking at a typical 90-day pilot budget for three organizations, especially when it comes to handling one or two use cases in a HIPAA-compliant cloud, you're probably looking at somewhere between $250k and $600k. It's a pretty wide range, but it really depends on the specific needs and details of the project. The exact amount really depends on how well you connect with EHR systems and how much TEFCA testing you need to do. Here are some important things to keep in mind: First off, make sure you're paying attention to Business Associate Agreements (BAAs) and data-use agreements. Next up, you'll want to get those EHR sandbox credentials sorted out. Don’t forget about the onboarding for UDAP trust - that's a big deal! And lastly, aim to gain access to the QHIN sandbox. These are all key steps to keep things running smoothly!

Common pitfalls (and fixes)

Hey, I see you’re considering putting PHI on-chain to make things easier, huh? Just a heads-up: it’s probably not the best idea. Seriously, it’s better to steer clear of that! Sticking with hashes, off-chain storage, and FHIR pointers is more than enough. Trust me, you’ll be really glad you took care of this when audit season comes around! (hhs.gov).

• If you’re just brushing off UDAP/FAST with the excuse that “we already use SMART,” maybe it’s time to reconsider that. Hey, just a heads up--TEFCA FHIR is rolling out that FAST Security requirement by 2026. So, it’s a smart move to start planning your authentication system now instead of waiting until the last minute! (blog.hl7.org).
• Try to steer clear of creating APIs that aren't standard. Hey, take a look at those IGs listed by CMS. They'll definitely save you some time and hassle when it comes to redoing stuff. Plus, they'll make the whole certification and reporting process way smoother later on! (cms.gov).
• Don't just put TEFCA on the back burner and think of it as something to deal with later. So, even if you don’t end up connecting within the next 90 days, be sure to set up your endpoints, tokens, and audits in a way that makes things easy for you later. When it’s finally time to link up with a QHIN, you’ll want it to be a simple configuration tweak instead of having to redo everything from scratch. Trust me, it’ll save you a lot of headaches down the road! (rce.sequoiaproject.org).

What 7Block Labs will do in a 90-day engagement

We kicked off Week 1 with an awesome workshop on risk and compliance. We dove into the basics of HIPAA SRA, chatted about information blocking, and even took a closer look at TEFCA and QHIN options. It was a great way to get everyone on the same page!

• Get started on rolling out Ledger, FHIR, and identity reference in your HIPAA-compliant cloud setup.
• Get ready for some exciting stuff with UDAP/FAST Security enablement, along with some useful scaffolding for the SMART app!
• Hey, make sure to take a look at the VC 2. Let’s dive into the 0 Credential schema and the way the verifier flow operates. We're excited to launch our pilot KPI dashboards, and along with that, we're introducing a CMS/TEFCA-readiness checklist.

The takeaway

There's a 90-day pilot program happening in the U.S. focused on blockchain technology. Absolutely, healthcare can really take off if you dive into FHIR, SMART, and UDAP. It’s crucial to keep that protected health information (PHI) off the chain. Plus, integrating with TEFCA pathways will definitely help. Just make sure you choose a use case that really highlights any multi-party friction--you want to show how it all comes together! As you're working on your design, keep an eye on the 2026-2027 rules coming down the pipeline. It’s all about demonstrating value quickly--ideally within just a few weeks. Organizations that get both of these right are the ones that have what it takes to navigate procurement successfully and really ramp up their growth.

If you’re in the market for an easy-to-use blueprint and a talented engineering crew, 7Block Labs has got your back. They can jumpstart your discovery sprint in just two weeks and get a solid pilot up and running for you in about a quarter. Pretty great, right?
