Denial OS

HIPAA · Business Associate Agreement

Sign the BAA before the first EOB lands.

Denial OS operates as a Business Associate under HIPAA. Most practices we work with are Covered Entities — which means a signed BAA is the prerequisite to processing any patient PHI through our platform. We make this fast and free.

What our BAA covers

  • Permitted uses and disclosures of PHI strictly limited to providing the appeals service.
  • Required safeguards: encryption at rest, encryption in transit, access controls, audit logging.
  • Subcontractor flow-down — every downstream vendor (Anthropic, Supabase, Stripe, Resend, Phaxio) has executed a BAA with us where they touch PHI.
  • Breach notification within HIPAA Breach Notification Rule timelines.
  • Data return / destruction obligations on termination.
  • Mutual cooperation on patient access, amendment, and accounting requests.

How to request the template

Email legal@twinflamegroup.com with your practice's legal name, NPI or tax ID, and the name + email of the person authorized to sign. We'll send a countersignable PDF the same business day. If you need a redline against your own template, attach yours and we'll turn it within 48 hours.

Already a customer?

If you started a trial first and now need a BAA, that's fine — we'll get it executed before any production EOB upload. Email the same address and reference your account.
