How to Switch Doctors on Medicare: Steps to Follow

Yes, you can change doctors on Medicare whenever you need to, and you don’t have to jump through a maze of paperwork to do it. Whether you’re on Original Medicare or a Medicare Advantage plan, the process is usually quick—once you know what to look for.

Below you’ll find a friendly, step‑by‑step guide that tells you when you can switch, how to find a new provider, what costs to expect, and a few handy tips so you never get an unexpected bill. Grab a cup of coffee, settle in, and let’s walk through it together.

Why You Should Switch

People change doctors for all kinds of reasons. Maybe you’re moving to a new city, your longtime physician is retiring, or you simply feel that the care isn’t quite right for you. Some of the most common triggers include:

• Relocation – your current doctor’s office is now a two‑hour drive.
• Doctor retirement or closure of the practice.
• Feeling unheard, rushed, or uncomfortable during visits.
• Your current doctor no longer accepts Medicare assignment.
• Changes in your Medicare plan that affect which doctors are in‑network.

While a new doctor can bring fresh perspectives and better communication, there are a few things to keep in mind. Switching may temporarily interrupt continuity of care, and you might face higher out‑of‑pocket costs if the new provider is out of network. Balancing those benefits and risks is the key to a smooth transition.

A Real‑World Example

Maria, 71, moved from Ohio to Florida to be closer to her grandchildren. Her original PCP retired the week she arrived. By checking the official Medicare physician comparison tool, she found a new doctor who accepted Medicare assignment. Within two weeks she had a fresh set of medical records transferred, and she saved about $200 a year on co‑pays because the new doctor was in‑network for her Advantage PPO plan.

Medicare Types

Plan Type	Can you switch anytime?	Network Requirement	How to pick a new doctor
Original Medicare (Parts A & B)	✅ Yes – any doctor who accepts Medicare assignment.	None (but doctor must accept Medicare).	Use the Medicare Provider Directory or a Medicare doctor list.
Medicare Advantage HMO	✅ Yes, but only to doctors in‑network.	Strict network.	Call member services or view the plan’s online provider list.
Medicare Advantage PPO	✅ Yes – in‑network for lower cost, out‑of‑network allowed at higher cost.	Preferred network (optional).	Same as HMO + verify out‑of‑network fees.

According to eHealthInsurance, Original Medicare lets you change providers at any time as long as the doctor accepts Medicare assignment. The only time you’ll hit a wall is with a Medicare Advantage HMO that insists on staying within its network.

Original Medicare – Simple Steps

1. Call the doctor’s office and ask, “Do you accept new Medicare patients and take Medicare assignment?”
2. If they say yes, schedule your first appointment. No paperwork with Medicare is needed.
3. Optional: Ask the office for a Medicare participation verification letter for your records.

Medicare Advantage HMO – What You Need to Do

1. Log into your plan’s member portal or call the number on the back of your ID card.
2. Request a list of in‑network doctors (often called a Medicare doctor list).
3. Select a new doctor, then tell the plan you’re switching. They’ll send you a new ID card with the updated PCP name.
4. Confirm the doctor’s acceptance of new Medicare patients before your first visit.

Medicare Advantage PPO – Flexibility with a Cost Twist

1. Search the plan’s online provider directory for in‑network doctors.
2. If you prefer a doctor outside the list, double‑check the out‑of‑network cost share—usually a higher copay.
3. No formal notification is needed for out‑of‑network switches, but it’s polite to let your old doctor know you’re moving on.

Finding a New Medicare Doctor

Finding the right provider can feel like looking for a needle in a haystack, but the good news is Medicare gives you powerful tools to make the search painless.

Official Medicare Provider Directory

The Medicare Provider Directory is the most reliable source. It lets you filter by specialty, distance, and whether the doctor accepts Medicare assignment. Think of it as a searchable, up‑to‑date “Medicare doctor list.”

State‑Specific Lists

Many state health departments publish PDFs of participating physicians. A quick Google search for “your state Medicare provider directory” usually surfaces a downloadable list that’s easier to skim than the national site.

Third‑Party Search Tools

Sites like eHealthInsurance’s physician compare or Medicare.org’s doctor finder aggregate the same data and add user reviews, which can be helpful when you’re weighing bedside manner against location.

In‑Network vs. Out‑of‑Network Cost Snapshot

Scenario	Typical Cost (Part B)	Notes
Participating doctor (accepts assignment)	20 % of Medicare‑approved amount after deductible	No surprise bills.
Non‑participating doctor (does not accept assignment)	Up to 15 % above the Medicare‑approved amount	Doctor can bill you for the excess.
Out‑of‑network PPO doctor	Higher coinsurance (often 30‑40 %) + possible balance‑billing	Check your plan’s out‑of‑network fee schedule.

Checklist Before You Call

• Ask, “Do you accept Medicare assignment?”
• Confirm they’re taking new Medicare patients.
• Request their NPI number (National Provider Identifier) so you can verify on Medicare.gov.
• Note the office’s billing phone number for future reference.

Costs & Billing When You Switch

Switching doctors doesn’t automatically mean you’ll face a price jump, but there are a few financial nuances to keep in mind.

What You May Pay

• Original Medicare: 20 % coinsurance after the Part B deductible, as long as the doctor is a participating provider.
• Non‑participating providers: Up to a 15 % surcharge on top of the Medicare‑approved amount (as noted by eHealthInsurance).
• PPO out‑of‑network: Higher coinsurance and possible balance‑billing, which can feel like a surprise attack on your wallet.

How to Dodge Surprise Bills

1. Verify participation status before the first visit. A quick phone call can save you hundreds later.
2. Ask the office to submit claims directly to Medicare. If they ask you to submit, you’ll need to keep the receipts and follow up on the Explanation of Benefits (EOB).
3. Keep your EOBs. They show what Medicare paid and what, if anything, you owe.

Sample EOB Walkthrough

Imagine you visited Dr. Lee for a routine check‑up. After Medicare processes the claim, your EOB will list:

• Service: Office visit – CPT 99213
• Medicare approved amount: $100
• Medicare paid (80 %): $80
• Patient responsibility (20 %): $20
• Deductible status: Met

If you see an extra line that says “Non‑participating provider surcharge,” that’s the 15 % extra you’d owe. Having the EOB in hand lets you question any unexpected charge right away.

When Switching Isn’t Straightforward

There are a few special situations where you’ll need to pause and read the fine print.

Enrollment Windows

• Open Enrollment (Oct 15–Dec 7): You can switch Medicare Advantage plans or revert to Original Medicare.
• Annual Election Period for Advantage (Jan 1–Mar 31): Allows you to change from one Advantage plan to another, which may affect which doctors are in‑network.
• Outside these windows, you’ll need a qualifying life event (move, loss of other coverage, etc.) to switch plans.

Doctor Opting Out of Medicare

If your current doctor decides to opt out of the Medicare program, they can no longer bill Medicare for your visits. You can still see them, but you’ll pay the full price out of pocket. In that case, the best move is to locate a new provider who is actively participating.

HMO Waiting Periods

Some HMO plans impose a 30‑day waiting period before a new primary care physician becomes effective. During that time you can still see your old PCP for urgent needs, but routine appointments should be scheduled after the waiting period.

Step‑by‑Step Quick‑Reference Guide

Action	Where to Do It
Identify your Medicare plan type	Medicare Summary Notice or plan ID card
Verify new doctor accepts Medicare assignment	Phone call to the doctor’s office
Update or confirm enrollment (if HMO/PPO)	Member‑services phone number or online portal
Transfer medical records	Request from old doctor’s office (written consent may be needed)
Confirm new ID card / effective date	Mail or electronic confirmation from your plan
Review first bill / EOB	Check for surprise charges and keep records
