What Your Doctor Wishes You Knew About Medicare Coverage

Your doctor’s office sees it all. From surprise copays to coverage denials, here’s what they want every patient to understand during Annual Enrollment. 

Start with your Doctors

Doctors and clinics interact with Medicare Advantage plans every single day. They see patterns with the surprise copays, denied services, prior authorization delays, and the patients who unknowingly pick plans that limit their care.

And the truth? Most of these issues could have been avoided with a quick plan review during the Annual Enrollment Period (AEP).

As we head into 2026, here’s what healthcare providers wish every Medicare patient understood before locking in their coverage (KFF, 2025). 


Your Plan Can Change Your Access, Even to Your Favorite Doctor

Networks shift every year as carriers renegotiate contracts–and sometimes, providers chose to leave networks due to reimbursement changes. According to national analyses, Medicare Advantage network changes are increasingly common and can significantly impact access (KFF, 2025). 

This means:

    • A doctor you’ve seen for years may suddenly become out-of-network
    • A specialist you rely on might no longer accept your plan in 2026
    • Large medical groups sometimes switch networks mid-year
Why it matters: Going out-of-network can raise your out-of-pocket costs dramatically or prevent you from seeing your preferred doctor at all.
 

Coverage Rules Vary Between Plans

Many patients assume Medicare Advantage plans follow one standard set of rules. Not true. Coverage for: 

    • MRIs
    • Physical Therapy
    • Behavioral Health
    • Durable Medical Equipment
    • Home Health
    • Cardiac Care

…Can vary widely between plans, even within the same county (NCOA, 2025). 

Most Importantly:

    • Your doctor does not set coverage rules. Your insurance plan does.

So while your provider may recommend a service, the plan may require: 

    • Prior authorization
    • Step Therapy
    • Proof of “Medical Necessity”
    • Using Specific Providers or Locations
This is why choosing the right plan matters so much. 

Drug Formularies Aren’t All the Same

Studies show that:

    •  Many beneficiaries see their prescription tiers shift year-to-year
    • Some drugs are removed entirely
    • Prior authorization requirements are increasing (CMS, 2026). 
This means that your 2025 plans might suddenly: 
 
    • Push a medication into a more expensive tier
    • Require prior authorization
    • Stop covering a brand-name option
    • Increase costs at your preferred pharmacy (NerdWallet, 2025) 

If you take medications daily, this review is non-negotiable. 


A Quick Review Saves Frustration Later

Doctors consistently report seeing patients face:

    •  Unexpected copays
    • Denied Claims
    • Delayed surgeris or treatments
    • Medication switches due to cost
    • Surprise out-of-network charges
Most of these issues could be prevented with a simple annual coverage review.

According to KFF’s 2025 Medicare Advanatage analysis, plan changes to prior authorization and cost-sharing are among the top reasons patients experience delays and surprise bills (KFF, 2025). 

Five minutes now can save weeks of frustration later.
