What gets attested for health systems?

Operational events emit an H33-74 proof at the moment they occur: prior authorization decisions, clinical decisions from AI decision support, HIPAA disclosure events (minimum-necessary determinations and accounting-of-disclosure entries), prescribing decisions, quality measure events, adverse event reports, and credentialing and privileging decisions.

Is the primitive different for healthcare?

No. This is the same H33-74 primitive — the portable 74-byte post-quantum evidence attestation — applied to healthcare. The primitive is unchanged and produces the same 74 bytes; only the application context differs.

Which regulations does the evidence support?

H33-74 produces evidence that supports requirements under HIPAA, the EU AI Act (high-risk AI in clinical decision support), GDPR, SOX, and CMS Meaningful Use / Promoting Interoperability audit trails. It does not by itself make an organization fully compliant; it produces independently verifiable evidence that supports those requirements.

Can auditors verify proofs without contacting H33?

Yes. Each H33-74 proof is independently verifiable by an offline verifier. Auditors verify the post-quantum-signed proofs directly, with no contact to H33 required.

Does the evidence survive system, vendor, and chain change?

Yes. The proof outlives the system that produced it, the vendor that hosts it, and the chain it was anchored to. When a hospital switches EHR vendor, or a system, cloud, database, or anchor chain is replaced, prior proofs remain independently verifiable with zero technical dependency on the prior vendor.

H33-74 for Healthcare — Chain-Portable Clinical Evidence

H33-74 for Healthcare

Related · tier-1 reading. For what a portable artifact actually is, see Portable Artifact.

This is H33-74 — the portable 74-byte post-quantum evidence primitive that produces and anchors operational proof — applied to healthcare. The primitive is unchanged; only the application context differs. Chief Compliance Officers, Chief Medical Information Officers, HIPAA Privacy Officers, Chief Quality Officers at hospitals, payers, and health systems need operational evidence that survives infrastructure change, vendor turnover, and regulatory horizon shifts. H33-74 makes that evidence cryptographically verifiable and chain-portable by construction.

The asset may move. The evidence remains. Every approval, transfer, decision, and policy action your healthcare produces gets a 74-byte post-quantum-signed proof at the moment it happens. The proof outlives the system that produced it, the vendor that hosts it, and the chain it was anchored to.

What gets attested in healthcare

Each of the following operational events emits an H33-74 proof at the moment it occurs. The collection composes into the operational history that audit, compliance, and regulatory teams reconstruct from.

Prior authorization decisions: approval, denial, peer-to-peer review, appeal disposition.
Clinical decisions emitted by AI clinical decision support systems.
HIPAA disclosure events: minimum-necessary determinations, accounting-of-disclosure entries.
Prescribing decisions: e-prescribing transmissions, controlled-substance checks, formulary overrides.
Quality measure events: care gap closure, quality bonus determinations.
Adverse event reports and incident classifications.
Credentialing and privileging decisions.

Regulatory pressure that already justifies this

Healthcare is regulated under frameworks whose audit horizons now extend past the lifetime of the systems and vendors holding the evidence. H33-74 produces evidence that survives that horizon:

HIPAA. Privacy Rule, Security Rule, Breach Notification Rule, accounting of disclosures. See: HIPAA crosswalk
EU AI Act. High-risk AI in clinical decision support. See: EU AI Act crosswalk
GDPR. European patient data. See: GDPR crosswalk
SOX. Publicly listed payers and providers. See: SOX crosswalk
CMS Meaningful Use / Promoting Interoperability. EHR audit trails.

Scenarios this changes

Hospital switches EHR vendor

Every clinical decision support output, every prior authorization, every accounting-of-disclosure entry from the prior EHR remains independently verifiable. The new EHR carries forward zero technical dependency on the prior vendor.

Office for Civil Rights requests disclosure history from five years ago

The original PQ-signed proofs of each minimum-necessary determination and accounting entry are produced. The compliance officer, the requestor, the data category, and the determination basis are all in each proof.

Payer faces RADV audit on AI-assisted risk-adjustment coding

The proof of every AI suggestion, every coder review, every supporting clinical evidence link, and every final coding decision is produced. The audit team verifies each one directly.

What survives versus what gets replaced

Survives

Every approval, decision, transfer, compliance check, and policy action your operation produced — independently verifiable forever.

Gets replaced as normal lifecycle work

The core systems, the vendor SaaS contracts, the cloud, the database product, the chain you anchored to. Each replacement is engineering work, not an existential project.

Healthcare operational history compounds in value. Five years of approvals, decisions, and compliance determinations are usually worth more than the systems that produced them. H33-74 keeps that history independent of the infrastructure.

The proof itself is the flagship H33-74 attestation applied here — see the general evidence patterns this vertical reuses: AI attestation and AI decision attestation. Where protection must be shown to stay true over time (continuous control evidence), HATS records that history on this same H33-74 substrate.

How to start

Three integration patterns, ordered by how invasive each is.

Pattern 1 — Receipt at the policy engine

The decision system (policy engine, approval workflow, AI scorer) emits an H33-74 proof for every decision at the moment it is made. No change to upstream systems. Auditors verify proofs directly.

Pattern 2 — Receipt at the system of record

Each system of record (treasury, claims, records, EHR) is wrapped so that committed transactions emit H33-74 proofs in addition to the existing audit log. Existing systems remain unchanged. Proofs become a parallel canonical record.

Pattern 3 — Receipt at the integration bus

Service mesh or integration bus intercepts cross-system events and emits H33-74 proofs. Highest reach, requires bus integration. Useful where systems-of-record cannot be modified.
