Top Blockchain Healthcare Use Cases Beyond Medical Records

---

Why this matters now

Over the next two years, a bunch of U.S. policies will push for multi-party interoperability in ways that a tamper-evident, shared log is really great at:

• Drug Supply Chain Security Act (DSCSA): The FDA is rolling out a phased approach to enforce electronic traceability, pushing for more interoperability in daily operations through late 2025 and into 2026. Some exemptions are in place that will expire on the following dates: May 27, 2025, for manufacturers and repackagers; August 27, 2025, for wholesalers; and November 27, 2025, for large dispensers. Small dispensers get a bit more time, with their exemption lasting until November 27, 2026. You can find more details on the FDA website.
• CMS Interoperability & Prior Authorization Final Rule (CMS‑0057‑F): Starting January 1, 2026, there will be stricter turnaround times for prior authorizations--72 hours for expedited requests and 7 days for standard ones. By January 1, 2027, FHIR-based APIs will be required, but there is some leeway allowing for all-FHIR Prior Auth without needing X12 278 for now. You can read more in the details provided by CMS.
• Medical device cybersecurity: With section 524B now in play, manufacturers must include Software Bill of Materials (SBOMs) and solid cyber plans in their premarket submissions. The FDA is set to finalize some guidance updates in 2025. For more insights, check out the FDA's FAQ.
• National exchange: The TEFCA Common Agreement v2.0 is taking things up a notch by integrating FHIR API into what’s being dubbed the “network of networks.” This will facilitate verifiable identity and audit overlays, making everything a bit smoother. For the full scoop, visit Healthcare IT News.

Here’s a look at some of the coolest blockchain use cases we’re rolling out with our clients from 2025 to 2027--going beyond just medical records. We’ve broken it down into easy-to-follow steps, key performance indicators, and a few things to watch out for.

1) DSCSA compliance at scale: product verification, interoperable traceability, and chargeback automation

Why it’s hot

• The DSCSA is gearing up for electronic package-level tracing that actually works together, and any exemptions are set to expire by 2025-2026. Plus, regulators are out there already using verification tools. Check it out on (fda.gov).
• According to the FDA and GS1, EPCIS is the way to go for standardized data exchange. On top of that, solution providers have really stepped up their game with conformance programs. You can find more info here: (supplychain.gs1us.org).

What’s working in the wild

• MediLedger’s Product Verification and Contracts & Chargebacks solutions are all the rage when it comes to permissioned blockchain technology. They’re doing a fantastic job with sub-second product verification, covering most U.S. medicines, and tackling those pesky chargeback disputes by sticking to shared business rules. Check it out here: (mediledger.com)
• The NABP snapped up MediLedger’s Product Verification System (PVS) and integrated it into Pulse by NABP. This tool is now being utilized by regulators in over 20 states--as well as DEA field offices--for almost real-time verification (like tracking down that elusive Ozempic in Arkansas back in January 2025). Read more about it here: (nabp.pharmacy)
• When it comes to EPCIS maturity, vendors are on top of their game, having secured all GS1 US EPCIS trustmarks to guarantee that their file-level conformance for DSCSA messages is spot on. More info here: (tracelink.com)

Reference architecture

• Data layer: We're using GS1 EPCIS 1.2/1.3 for those serialized events, which are stored off‑chain in your traceability platform. Check it out here!
• Ledger layer: Think of a permissioned network (like Hyperledger Besu or Fabric) that only keeps cryptographic fingerprints of those EPCIS event batches, along with dispute states and the ins and outs of product verification requests and responses.
• Directory/VRS: We’re integrating with the industry’s Verification Router Service and Pulse. This helps us route verification pings and regulator queries while keeping personal info under wraps. For more about it, take a look at this link!

KPIs to track

• Product verification SLA: We aim for over 95% of responses to come in under 1 second for both receiving and returns. (mediledger.com)
• Dispute cycle time: We’ve managed to cut down chargeback resolution from days to just hours thanks to our shared rules and evidence trail. (mediledger.com)
• DSCSA readiness: This includes the percentage of inbound EPCIS that matches at receipt, the fraction of serialized returns we accept, and how quickly we respond to regulators.

Implementation tips

• Skip storing EPCIS payloads directly on-chain. Instead, hash them and keep the original data in your DSCSA platform. Use the blockchain mainly for notarization and handling disputes.
• Get your identifiers (like GLN, GTIN, and SSCC) and aggregation rules sorted out early on. Make sure to reconcile your master data with your trading partners. Check it out here: (supplychain.gs1us.org).
• Get ready for the gradual rollout of EPCIS 1.3 after exemptions, kicking off with dispensers in Q3 2026. More details here: (gs1us.org).

2) Prior authorization and claims event transparency

Why it’s hot

CMS has set some clear deadlines for response times: you've got 72 hours for expedited cases and 7 days for standard ones. Plus, they’re expecting FHIR-based APIs to be in place by January 1, 2027. The good news is that HHS won't enforce X12-only rules if you stick with the all-FHIR route. This means that payers, providers, and vendors need to work together across their organizations while keeping track of everything in an auditable way. For more details, check out the CMS fact sheet.

Pattern that works

• Event sourcing: Capture every step in the PA process--like when you submit, pended info, get clinical attachments, and make decisions--as FHIR resources in your API. Don’t forget to add event hashes to a consortium ledger for tracking!
• Smart policies: Use smart contracts to enforce timing windows and handle exceptions. This way, you can trigger alerts or penalties if SLAs aren’t met, which is super handy for audits and state reviews.
• Data exchange: Store all your clinical content in the FHIR setup. Just keep it light on the blockchain with minimal, non-PHI metadata--think request ID, timestamps, decision code, and hash.

Immediate value

• Audit-ready clock: You've got a cryptographic proof showing exactly when you got extra documentation or made a decision.
• Faster appeals: With a shared state, the whole "he said/she said" situation gets cleared up, which means less friction and rework between payers and providers.
• Regulatory comfort: The ledger record, along with FHIR API logs, proves you're on the right side of CMS timelines and transparency standards. (cms.gov)

3) Provider credentialing, privileges, and cross‑network identity with verifiable credentials

Why it’s hot

Delays in getting providers onboard can really hold up revenue and access to care. With TEFCA shifting towards FHIR APIs across different networks and the W3C Verifiable Credentials (VC) family gearing up for v2.0, we’re in a pretty exciting place. Now, you can issue credentials that are cryptographically verifiable and selectively disclosable for things like licensure, board certification, DEA registration, and hospital privileges. Check out more about this at healthcareitnews.com.

How to build it

• Issuers: State boards, hospitals, specialty boards, and the DEA are stepping up as VC issuers.
• Wallets: Clinicians can store their credentials in either enterprise or personal wallets. With selective disclosure using BBS+ signatures, we can avoid oversharing. (w3c.github.io)
• Revocation: We keep status lists (bitstring revocation) on a permissioned ledger to ensure high availability and easy auditing. (w3c.github.io)
• Interop: We're working on mapping VC claims to CAQH data elements, which helps payers speed up primary source verification--though it won't completely replace it right off the bat. (caqh.org)

What to measure

• Cycle time: In our pilot programs, we managed to slice the initial credentialing time by 30-50% simply by reusing digitally signed stuff like licenses, education records, and NPDB checks.
• Re‑credentialing: It's as easy as the push of a button for updates whenever an issuer rotates or suspends a credential--no more manual outreach needed!

Guardrails

• Make sure to keep any personal info off the chain; the ledger should just have credential status lists and key registries.
• Set up your governance: establish a trust framework, figure out liability, and outline fallback processes (like what to do if a wallet is lost or in case of emergency overrides).

4) Medical device identity, SBOM attestation, and patch accountability

Why it’s hot

Starting March 29, 2023, all “cyber devices” are required to have SBOMs and cyber plans included in their premarket submissions. Plus, the FDA’s guidance for 2025 is ramping up the expectations even more. Hospitals are looking for ongoing assurance for their networked device fleets instead of just getting a bunch of PDFs. (fda.gov)

Pattern to implement

• Device DID: Give each device a unique decentralized identifier linked to its UDI and the manufacturer's PKI.
• SBOM anchoring: When a new version or patch bundle is released, hash it and post it to the ledger. Make sure to include machine-readable references like SPDX or CycloneDX.
• Zero-trust verify: Before connecting to clinical networks, hospital asset managers should check the device’s current firmware/SBOM hash against the ledger.
• Coordinated disclosure: Keep track of when vulnerabilities are reported, when manufacturers send out advisories, and when any fixes are deployed. This way, everything is auditable.

KPIs

• The percentage of deployed devices that have verifiably up-to-date SBOMs.
• The average time it takes to fix an issue (MTTR) from when it's disclosed until the patch is applied, complete with a documented trail for regulators and auditors.

5) Clinical trial integrity, DCT orchestration, and privacy‑preserving AI

What’s driving this

The FDA just wrapped up its guidance for trials that include decentralized elements in 2024. Now, sponsors have to really show that their data is solid, especially when it comes to in-home visits, wearables, and local labs. To keep everything on the level, tying important trial events to an unchangeable log will help minimize disputes and make inspections smoother. You can check out more details on this over at fda.gov.

Practical patterns

• eConsent and protocol amendments: Keep your consent hashes anchored, track versioned amendments, and set time‑boxed consent scopes right on a ledger; don’t forget to stash the documents in your eTMF.
• ePRO/eCOA and sensor data: Add integrity stamps to batches (like hourly or by device session) on the ledger to show there’s been no back‑filling or “data drift.”
• IP and cold‑chain: Hash your shipping events and any temperature excursions to help manage deviations effectively.
• Privacy‑preserving AI: Leverage “swarm learning” for cross-site model training through a permissioned blockchain that takes care of secure onboarding, leader election, and parameter merging--keeping all that raw data local. (nature.com)

Real‑world signals

• Triall teamed up with Mayo Clinic to incorporate blockchain technology for ensuring data integrity in a multi-site pulmonary arterial hypertension study. This includes eClinical functions like eConsent and eTMF. You can read more about it here.

Bonus: RWE without data movement

• Combine a ledger audit layer with “clean room” methods for cross-dataset queries (like Datavant Connect paired with AWS Clean Rooms). This way, you can make the most of provenance while keeping data exchanges to a minimum. (datavant.com)

6) AI model and dataset provenance in clinical systems

Why it’s hot

ONC’s HTI‑1 final rule is all about making the algorithms in certified health IT more transparent. Meanwhile, NIST’s AI RMF offers a solid roadmap for managing risks. A ledger can really help keep everything organized, from data cards and training lineage to tuning checkpoints and deployment approvals. Check it out here: (healthit.gov).

Operating model

• Dataset cards: Keep track of the hashes for those training and validation datasets, along with any cohort filters and known exclusions.
• Model cards: Document the version and hyperparameters of your model, plus how it performed when it was first released. Don’t forget to link to any post-market drift monitoring events!
• Access logs: Create privacy-preserving proofs to show how the model is used, especially in high-risk clinical situations.

Outcome

• Safety investigations are quicker, and conversations with regulators become smoother since the provenance is easy to track, consistent, and tamper-proof.

7) Genomics: what to avoid, and what to do instead

Tokenized “genomic data marketplaces” have had a rough time lately. LunaDNA closed down in early 2024, and users of Nebula Genomics started facing service issues and a switch to a different operator in 2025. The takeaway? It’s best not to attempt storing or trading sensitive omics data on a tokenized ledger. Instead, stick to using the blockchain just for audit trails and consent. (insideprecisionmedicine.com)

Safer blueprint

• Store your sequence data in Trusted Research Environments or cloud clean rooms. Make sure to log all consent and data-use events on a ledger to maintain clear provenance--this means tracking who accessed what, when, and under which IRB. Don't forget to use privacy-preserving techniques like linkage and tokenization when building your cohorts. (datavant.com)

Cross‑cutting best practices (that teams skip at their peril)

• Data off-chain, proofs on-chain: Let’s hash those big payloads like EPCIS, FHIR Bundles, and eTMF docs while keeping any PHI away from the ledger.
• Verifiable credentials for people and things: We can use DIDs/VCs for everyone involved, from clinicians to organizations, devices, and software builds. Just remember to keep those revocation/status lists right on the ledger. (w3c.github.io)
• Standards first:
  • Supply chain: Think GS1 EPCIS 1.2/1.3 and VRS. (supplychain.gs1us.org)
  • Clinical data: We’re looking at HL7 FHIR R4 and TEFCA CA v2.0 for API exchange expectations. (healthcareitnews.com)
  • Security: Keep in mind the FDA 524B SBOM expectations and aim for machine-readable SPDX/CycloneDX. (fda.gov)
• Governance before code: It’s a good idea to draft a multiparty operating agreement. This should cover membership, key management, data responsibilities, and exit rules.
• Permissioned, with optional public anchoring: We want to keep the business logic on a permissioned network, but periodically anchoring state roots to a public chain can add some extra tamper-resistance if the policy allows it.
• Measurable value: Before diving into sprint 1, let’s nail down 3-5 KPIs for each use case. Think about stuff like verification SLA, PA SLA compliance, credentialing cycle time, SBOM coverage, and eTMF inspection findings.

90‑day pilot plans you can start this quarter

• DSCSA Verification and Dispute Reduction
  • Scope: We’re involving 2 manufacturers, 1 wholesaler, and 2 dispensers, plus we’ll be integrating Pulse PVS/VRS.
  • Deliverables: We’ll roll out a verification SLA dashboard, set up chargeback rules on-chain, and create a regulator query playbook.
  • Success: We’re aiming for over 95% sub-second verification and a 40% boost in how quickly we resolve disputes. (nabp.pharmacy)
• Prior Authorization Audit Ledger
  • Scope: We're diving into one regional payer and teaming up with two big provider groups; utilizing the FHIR PA API; implementing event hashing for the chain; and setting up timing policies in our smart contracts.
  • Success: We hit a home run with 100% of expedited decisions made within 72 hours, thanks to a solid cryptographic audit trail; plus, we managed to cut the appeal cycle time by 15%. (cms.gov)
• Provider VC credentialing
  • Scope: We're tackling one hospital system, one payer, and the state board sandbox. Our goal is to issue verifiable credentials for licensure and privileges, act as a verifier during payer intake, and keep a revocation list on the blockchain.
  • Success: We managed to cut the initial credentialing cycle time by 30%, and guess what? There haven't been any NCQA audit findings linked to gaps in credential provenance. (w3c.github.io)
• Device SBOM Attestation
  • Scope: We're looking at 2 device families spread across 3 hospitals. This involves SBOM hashing and attestation, plus verifying assets when they join the network.
  • Success: Over 90% of devices now have an up-to-date SBOM. We've also managed to cut down the mean time to resolution (MTTR) on security advisories by 25%! (fda.gov)

Common traps and how to avoid them

• Don’t put PHI on a blockchain. Stick to using hashes, but make sure there's a strong connection to off-chain storage.
• Creating a network without a central operator? Consider bringing in a neutral convener and set up an operating budget--think of it like “network as a product.”
• Don’t overlook the timing of standards releases. Get ready for the EPCIS 1.3 “sunrise” and the phased expansion of TEFCA FHIR; make sure your design can handle a mix of maturity levels. Check out more on this at gs1us.org.
• Be cautious of overfitting to just one jurisdiction. Keep in mind, U.S. regulations (CMS, FDA, ONC) don’t line up with the timeline for the EU AI Act--so it’s better to design flexible policy knobs rather than strict, hard-coded rules. Dive into more details at health.ec.europa.eu.

What this looks like in your stack

• Integration plane:
  • We're talking FHIR server(s) to handle clinical workflows, an EPCIS gateway for our supply chain needs, and some solid device management with an SBOM registry.
• Trust plane (blockchain):
  • Here, we’ve got smart contracts ready for event attestation, process SLAs, VC status lists, and workflows for resolving disputes.
• Security and identity:
  • This covers a range of things like PKI, DIDs/VCs, HSM-based key custody, and automated key rotation to keep everything secure.
• Observability:
  • Think cross-party dashboards for tracking things like verification SLA, PA timelines, credential statuses, and SBOM coverage, plus reports for regulators that can be exported.

Bottom line

If you're diving into blockchain in the healthcare space, don't get caught up in the big EHR systems. Instead, focus on the connections: those multi-party workflows that you just can't secure or audit with one single record system. Between 2025 and 2027, the most compelling business opportunities will be around things like DSCSA, prior authorization, credentialing, device cybersecurity, and maintaining trial integrity. Each of these areas will be further influenced by new regulations and industry roadmaps. The tech is all set to go; it's really the governance and KPIs that will determine whether your investment pays off.
