Medicare Advantage Network / Prior Authorization
Medicare Advantage (Part C) plans must cover everything Original Medicare covers, but they often require you to follow network rules and may require prior authorization for certain services. The plan can also have different copays and step-by-step requirements.
Why it Matters
Even if a service is medically appropriate, you may pay more (or risk denial) if you go out of network or skip required approvals. These rules can also affect timing for tests, specialists, therapy, and procedures.
Action Steps
Confirm the provider/facility is in network before the visit or test.
Ask the plan: “Is prior authorization required for this service?”
Keep plan contact info handy and document reference numbers for calls.
If a service is denied, ask about appeal rights and what documentation is needed.
