Signed rails for the three biggest reimbursement fights.

Prior auth, claim denial recovery, and reimbursement negotiation get handed off between provider and payer agents over A2A, with HIPAA-safe ALCOA+ receipts at every step. It's the audit trail every regulator and appeals adjudicator already wants to see.

The three fights eating into US healthcare margins

US providers lose about $262 billion a year to administrative friction with payers. The three biggest culprits are prior auth backlogs, claim denials (the initial denial rate is around 12%), and reimbursement rate disputes. All three fit agent-to-agent work well. They're repetitive, driven by evidence, and bound by published rules. None of them should ever run on unsigned messages.

A2A Healthcare gives provider-side agents and payer-side agents a signed rail to fight these out. It's fast, it's auditable, and it's HIPAA-safe. PHI never leaves the provider's system. Only signed fingerprints and structured claim envelopes travel over the wire.

The three use cases

1. Prior Auth

The provider agent submits a structured PA request with evidence fingerprints attached. The payer agent responds with a signed approval, denial, or request for information. We're targeting a median round-trip of 4 hours, not 4 days.

2. Claim Denial Recovery

When a claim gets denied, the ClaimDenialRecovery agent puts together the appeals packet. That's the evidence trail, the coding rationale, and the clinical justification, all in one, and sends it back over A2A. Every appeal gets its own receipt.

3. Reimbursement Negotiation

Out-of-network and rate-disputed claims get a signed negotiation envelope. Both sides see the exact same agreed-rate fingerprint. No phone tag, no re-sending faxes.

Frequently asked

Does this require payer cooperation to work?

Some workflows need both sides. The provider and payer each have to run an A2A agent to get the fast round-trip. Others, like denial appeal packet assembly and evidence chain receipting, work with just the provider side and still produce a regulator-ready audit, even if the payer is still using legacy rails.

How is this HIPAA-safe if it touches PHI?

PHI never leaves the provider's system. The A2A wire format only carries structured claim envelopes (CPT codes, ICD-10 codes, claim IDs, evidence hashes) and signed receipts, not the actual clinical notes. The PHI stays in the provider's existing system. The receipt just proves the agent acted on a specific document's fingerprint, not the document itself.

Is this only for US? Does it work in EU?

The core rail (signed envelopes, did:hive identity, ALCOA+ receipts) works the same everywhere. The pre-built workflows ship with US payer adjudication rules (CMS, major commercial payers). EU and UK rule packs are available on the Founder tier.

Can this be used by an in-house provider IT team or only an integrator?

Both. The wire format and SDK are public. In-house teams typically wire it into an existing EHR or claims engine in 1 to 2 weeks. For integrators and large provider groups, we offer a managed-deploy option on the Provider Group tier.

What's the ClaimDenialRecovery rate?

The industry baseline for appealed claims is roughly a 40 to 60 percent overturn rate. Your specific results depend on your denial reasons, your payer mix, and how well your original documentation backs up the claim. The receipt rail doesn't change the medical-necessity logic behind a claim. It changes how fast and how cleanly your appeal lands in front of the payer.

Is there a free tier for small clinics?

Yes. The Bazaar 'Hire' tier costs $5 a claim with no monthly minimum. Small clinics and solo practitioners usually start there. The Provider Group tier makes sense once you cross around 200 claims a month.
