How to Switch Primary Care Doctors Without Losing Your Records

People switch primary care doctors for ordinary reasons: a move, a new job with new insurance, a doctor who retired, or a practice where you could never get seen when you were sick. Whatever the reason, the switch itself is simple once you know which rules apply to your plan. Here’s how to do it in four steps, and how to make sure nothing falls through the gap between the old practice and the new one.

Step 1: Check what your plan requires

Whether you have to name a primary care doctor, and how you change one, depends on your coverage:

Your coverage	Must you name a primary care doctor?	How to switch
Original Medicare	No	See any doctor who takes Medicare
Medicare Advantage HMO	In most HMOs, yes	Call your plan. Your plan decides when the change takes effect
Medicare Advantage PPO	No	Use doctors in the plan’s network to pay less
Florida Medicaid managed care	Yes; the plan assigns one if you don’t choose	Call your plan. You can change at any time
Marketplace or job-based HMO or POS	Usually	Call your plan
Marketplace or job-based PPO or EPO	Check your plan	Choose a doctor in the network to pay less

Medicare. With Original Medicare you can see “any doctor or hospital that takes Medicare, anywhere in the U.S.” (Medicare.gov), and the Medicare handbook answers the question directly: you don’t need to choose a primary care doctor (Medicare & You 2027). Medicare Advantage is different. “In most HMOs you need to choose a primary care doctor” (Medicare.gov), while PPO members don’t have to (Medicare.gov). Medicare’s model member handbook for HMO plans tells members they can change their primary care doctor for any reason, at any time, and leaves each plan to say when the change starts (CMS).

Florida Medicaid. The state’s contract with Medicaid managed care plans requires them to let members change primary care doctors at any time. If the request misses the plan’s monthly cut-off date, the change takes effect on the first day of the next month (Florida AHCA).

Marketplace and job-based plans. An HMO “usually limits coverage to care from doctors who work for or contract with the HMO” (HealthCare.gov), and an EPO covers services only in the plan’s network, except in an emergency (HealthCare.gov). With a PPO you pay less in the network but can go outside it for an additional cost (HealthCare.gov). If your plan does require a primary care doctor, federal rules let you pick any participating primary care provider who is available to accept you (45 CFR 147.138).

Step 2: Choose your new doctor

A primary care provider is the doctor, nurse practitioner or physician assistant “who provides, coordinates or helps a patient access a range of health care services” (HealthCare.gov). In practice, that’s the person who recommends screenings and vaccines, treats many physical and mental health problems, refers you to specialists when you need one, and answers your questions (MyHealthfinder).

MedlinePlus suggests weighing what your insurance covers, whether the provider is accredited, the location, the hours, and whether you like the provider’s personality (MedlinePlus). A few more questions are worth asking:

• Does the practice see you when you’re sick? Same-day or walk-in visits give you somewhere to go for everyday illnesses, short of the emergency room.
• What can be done on site? A practice that draws blood or runs an EKG in the building saves you a second trip.
• Does the provider speak your language? If not, MedlinePlus advises calling ahead to ask for an interpreter (MedlinePlus).
• Family medicine or internal medicine? Both are primary care. Internists, also called internal medicine doctors, specialize in adults (ACP).

Picking someone you’ll stay with matters. Healthy People 2030, the federal government’s health goals, notes that “People with a usual source of care have better health outcomes, fewer disparities, and lower costs” (Healthy People 2030).

Step 3: Move your medical records

Your records don’t follow you automatically. Under the federal privacy rule, doctors are allowed to share your information with each other for your treatment without your written permission (HHS), but they aren’t required to (HHS). So the National Institute on Aging suggests giving your new doctor the names and addresses of your former doctors; you’ll usually be asked to sign a release so the new office can request your records (NIA).

You can also get a copy yourself. A practice normally has up to 30 days to provide it, with one 30-day extension allowed (45 CFR 164.524), but in the words of HHS, “your doctor often can provide the information much sooner than that.” You can’t be refused your records because of an unpaid bill (HHS). The practice may charge a reasonable fee for copying and mailing, but not for searching for or retrieving your records (HHS). You can also ask, in writing, for an electronic copy of your records to be sent straight to the new practice (HHS).

Step 4: Book your first visit and bring the right things

For a first visit with a new provider, the CMS “From Coverage to Care” guide lists your insurance card, a photo ID, any completed forms and your copay, if you have one (CMS). Add these:

• Every medicine you take, including over-the-counter medicines, vitamins and herbal supplements. The AHRQ suggests bringing the medicines themselves (AHRQ).
• Your history: current conditions, past surgeries and illnesses, and the names and phone numbers of other doctors you see.
• Your questions, written down. Ask what each test is for and when you’ll get the results.

Why the handoff matters

A new doctor is a fresh start, and also a moment when things can slip. In one large health system’s records, only about a third (34.8%) of specialist referrals had a documented completed appointment (Patel et al., 2018), though the authors note that some visits outside the system may not have been recorded. A review of U.S. studies found that anywhere from 6.8% to 62% of lab test results were not followed up (Callen et al., 2012).

That’s why the Agency for Healthcare Research and Quality’s advice is to “make sure that someone, such as your primary care doctor, coordinates your care,” and not to assume that no news is good news (AHRQ). When you switch, ask your new provider to review any test or referral that was still pending with the old one.

Switching to Ambert

Ambert Medical Care Center is a primary care practice led by internal medicine, with offices in Miami Lakes and Kendall. It accepts Medicare, Medicaid, Marketplace and commercial plans; the insurance page has details, including Medicare and Medicaid, and the office can confirm your specific plan before your first visit.

The practice’s five providers, an internal medicine physician and four nurse practitioners, all speak English and Spanish, and both offices welcome walk-ins for same-day sick visits. At the Miami Lakes office, blood is drawn on site and EKGs, allergy testing and Pap smears are done in the building, so fewer things need a second trip. See primary care for everything the practice covers.

Call the Miami Lakes or Kendall office and ask which providers are taking new patients. The new patient guide covers what to bring, and if you’re coming from another practice, bring whatever records you have.
