The Deal You Actually Signed
Original Medicare almost never asks permission in advance — care happens, then Medicare pays its share. Medicare Advantage plans work more like the employer insurance you had at 45: for certain services, your doctor must get the plan's approval before the care is covered. That's prior authorization, and it's a core part of how Advantage plans manage costs — which, in turn, is part of how they fund $0 premiums and extra benefits.
This isn't hidden, but it's rarely felt until it applies to you. The services most commonly requiring authorization are the expensive ones: inpatient hospital stays, skilled nursing facility care, imaging like MRIs and CT scans, some outpatient surgeries, durable medical equipment, and certain specialty medications. Routine primary care and most everyday specialist visits typically don't require it.
Why Denials Happen — and Why Appeals Work
Most prior authorization requests are approved. When denials happen, the common causes are mundane: missing clinical documentation, a request that doesn't match the plan's coverage criteria wording, or a service the plan believes can start at a less intensive level. It's a paperwork negotiation between your doctor's office and the plan — and like most paperwork negotiations, persistence changes outcomes.
That's not just encouragement: federal reporting on Medicare Advantage has consistently shown that when denials are appealed, a large majority get overturned — yet only a small fraction of denials are ever appealed. The appeal system has multiple levels, deadlines the plan must meet, and an expedited track (72 hours) when your health can't wait. A denial is the opening position, not the verdict.
Your Playbook When Care Gets Denied
The process rewards the organized. Here's the sequence that works:
- Get the denial in writing — the notice must state the reason and your appeal rights
- Call your doctor's office first: many denials resolve with a peer-to-peer review or corrected documentation
- File the appeal (called a 'reconsideration') within 60 days — in writing, referencing the denial letter
- Ask your doctor for a letter of medical necessity that addresses the plan's stated reason directly
- If it's urgent, request an expedited appeal — decisions come within 72 hours
- Keep going: appeals that lose at the plan level go automatically to an independent outside reviewer
Choosing Plans With This in Mind
Prior authorization intensity varies by plan and carrier — some are notably lighter-touch than others, and recent federal rules have pushed plans toward faster decisions and streamlined electronic processes. It's a fair thing to weigh when comparing plans, especially if you already have conditions that involve imaging, specialists, or planned procedures. It's also one of the fundamental trade-offs against Medigap, which pairs with Original Medicare's largely permission-free structure at a higher monthly premium.
