Policies

SMART-on-FHIR scopes
Member-authorized endpoints require SMART-on-FHIR auth with member-consent scopes; tokens are short-lived and refreshable.
Backoff
Implement exponential backoff with jitter; honor 429 + Retry-After.
Application registration
All apps calling Patient Access must be registered with Anthem; CMS rule prohibits blocking access but allows rate-limiting and abuse mitigation.
Public read-only endpoints
Provider Directory and Formulary are public read-only; cache aggressively to minimize load.
