What does Medically Necessary mean?
A plan standard used to decide whether care is appropriate under its coverage rules.
Illustration — not a plan price
If care is denied under this standard, read the plan definition and the denial notice's appeal instructions.
The actual plan document controls. Verify its definitions, network, exclusions, dates, and amounts before relying on the illustration.
Definitions here are never for sale — no plan is recommended on a comprehension page.
