Medical Necessity
Draft — pending verification
This reference entry has not yet been verified against its authoritative source (Original definitions; regulatory facts to be verified against CMS-0057-F (89 FR 8758) and X12/HL7 documentation). Do not rely on it for production configuration until this notice is removed.
In more depth
What counts as medically necessary is defined by contract and regulated by program: Medicare coverage rules for MA (reinforced by CMS-4201-F's limits on plans' use of internal criteria), EPSDT for children in Medicaid, state mandates elsewhere. Criteria transparency requirements keep expanding across programs.
