Rette: AI-Powered Payer Policy Search for Medical Billers

AI-powered payer policy search for medical billers

Rette searches 70,855 policy documents from 263 US insurance payers and answers coverage questions in plain English, with citations back to the source policy. Ask about coverage criteria, prior authorization requirements, timely filing limits, or why a claim was denied - the way you would ask a colleague.

What you can do with Rette

• Search payer coverage policies. Find medical necessity criteria, prior auth requirements, and billing guidelines across the payer policy directory.
• Check NCCI edits. Validate Procedure-to-Procedure (PTP) bundling edits and Medically Unlikely Edit (MUE) unit limits straight from CMS NCCI data before you submit a claim.
• Decode denials and draft appeals. Paste a denial code or upload an EOB and get the reason explained, plus an appeal letter grounded in the payer's own policy.
• Look up CPT codes and NPI records. Instant CPT code lookup and NPI Registry search without leaving your workflow.

Security and HIPAA compliance

Rette is HIPAA compliant. Protected health information you bring into Rette — eligibility and claim status checks, remittance advice, and records from a connected EHR — is handled under administrative, physical, and technical safeguards, and we execute Business Associate Agreements with the subprocessors that handle it.

• Encrypted in transit and at rest. TLS 1.2+ on every connection. EHR credentials and raw 835 remittance payloads are encrypted at rest with AES-256-GCM.
• Scoped access. Remittance and denial data is isolated to your organization and resolved server-side, never from a client-supplied identifier.
• Independently reviewed. SOC 2 Type I, with Type II underway. Certifications, security documentation, and subprocessor details are published in our trust center.
