The three fights that drain US healthcare margin
US providers lose ~$262B/year to administrative friction with payers. The three biggest line items: prior auth backlogs, claim denials (initial denial rate ≈12%), and reimbursement rate disputes. All three are perfect agent-to-agent workflows — repetitive, evidence-driven, and bound by published rules. None of them are safe to run on unsigned messages.
A2A Healthcare gives provider-side agents and payer-side agents a signed rail to fight these out — fast, auditable, and HIPAA-safe. PHI never leaves the provider boundary; only signed hashes and structured claim envelopes move on the wire.
The three use cases
1. Prior Auth
Provider agent submits structured PA request with evidence hashes. Payer agent responds with signed approval, denial, or RFI. Median round-trip target: 4 hours, not 4 days.
2. Claim Denial Recovery
On denial, the ClaimDenialRecovery agent assembles the appeals packet — evidence trail, coding rationale, clinical justification — and submits it back over A2A. Every appeal is receipted.
3. Reimbursement Negotiation
Out-of-network and rate-disputed claims get a signed negotiation envelope. Both sides see the same agreed-rate hash. No phone tag, no fax retransmits.

A2A Healthcare vs the status quo
| Workflow | Today (fax/portal) | A2A Healthcare (Hive) |
|---|---|---|
| Prior auth submit | Fax, payer portal, 7-30 day wait | Signed envelope · median 4h round-trip |
| Denial appeal | Manual packet assembly, mail | ClaimDenialRecovery agent · signed appeal in minutes |
| Rate dispute | Phone tag, batch reprocessing | Signed negotiation · agreed-rate hash locked |
| Audit trail | PDF receipts, paper file | ALCOA+ chain · regulator-ready |
| PHI on the wire | Yes (HIPAA risk) | No — only hashes + structured envelopes |
Frequently asked
Does this require payer cooperation to work?
Some workflows are bilateral — both provider and payer must run an A2A agent to get the fast round-trip. Others (denial appeal packet assembly, evidence chain receipting) work unilaterally on the provider side and produce a regulator-ready audit even if the payer is still on legacy rails.
How is this HIPAA-safe if it touches PHI?
PHI never leaves the provider boundary. The A2A wire format carries structured claim envelopes (CPT codes, ICD-10 codes, claim IDs, evidence hashes) and signed receipts — not the underlying clinical notes. The PHI sits in the provider's existing system; the receipt proves the agent acted on a specific document hash, not the document itself.
Is this only for US? Does it work in EU?
The core rail (signed envelopes, did:hive identity, ALCOA+ receipts) is jurisdiction-neutral. The pre-built workflows ship with US payer adjudication rules (CMS, major commercial payers). EU/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 1-2 weeks. For integrators and large provider groups, we have a managed-deploy option on the Provider Group tier.
What's the ClaimDenialRecovery rate?
Industry baseline for appealed claims is roughly 40-60% overturn rate. Provider-specific results depend on denial reason mix, payer mix, and how well the original documentation supports the claim. The receipt rail doesn't change the underlying medical-necessity logic — it changes how fast and how cleanly the appeal gets in front of the payer.
Is there a free tier for small clinics?
Yes — the Bazaar 'Hire' tier at $5/claim has no monthly minimum. Small clinics and solo practitioners typically start there. The Provider Group tier kicks in when volume crosses ~200 claims/month.
