Medicare's referral rules depend on your plan type

Whether you need a referral to see a specialist depends entirely on which Medicare plan you have. Original Medicare (Part A and Part B) does not require referrals — you can see any doctor or specialist who accepts Medicare without asking your primary care doctor first. If you have a Medicare Advantage plan, most do require a referral, though the rules vary by plan and by doctor.

The difference matters because getting it wrong can cost you money. Seeing a specialist without a required referral in a Medicare Advantage plan may mean you pay a higher out-of-pocket cost, or the plan may not cover the visit at all. Knowing your plan type and calling ahead takes five minutes and can save you hundreds of dollars.

Key Takeaways

  • Original Medicare (Part A and Part B) never requires a referral to see any specialist who accepts Medicare.
  • Most Medicare Advantage plans require a referral from your primary care doctor before you see a specialist, but some specialists may be exempt from this rule.
  • Your Medicare Advantage plan's member handbook or customer service line lists which specialists need referrals and which do not.
  • Calling your plan before scheduling a specialist appointment takes minutes and protects you from unexpected out-of-pocket costs.
  • Emergency care and urgent care do not require referrals under any Medicare plan.

Original Medicare does not require referrals

If you have Original Medicare (Part A hospital insurance and Part B medical insurance), you do not need a referral to see any specialist. You can call a cardiologist, orthopedist, dermatologist, or any other specialist directly and schedule an appointment, as long as they accept Medicare. Your primary care doctor does not need to approve the visit or send any paperwork first.

This freedom comes with one condition: the specialist must accept Medicare. Most specialists do, but some do not. Before you schedule, ask the office whether they accept Medicare and whether they are accepting new Medicare patients. If a specialist does not accept Medicare, you would pay the full cost out of your own pocket — Medicare would not cover any of it.

Medicare Advantage plans usually require referrals

If you have a Medicare Advantage plan (also called Part C), the plan itself sets the referral rules, not Medicare. Most Medicare Advantage plans require you to get a referral from your primary care doctor before seeing a specialist. The referral tells the plan that your primary care doctor thinks you need specialist care, and it helps the plan manage your care and costs.

However, not every specialist requires a referral under every plan. Some Medicare Advantage plans let you see certain specialists — like gynecologists or eye doctors — without a referral. Your plan's member handbook lists which specialists need referrals and which do not. If you cannot find it in the handbook, call your plan's customer service number (on the back of your insurance card) and ask directly.

Getting a referral is usually straightforward. Call your primary care doctor's office and tell them which specialist you need to see and why. The office sends the referral to your plan electronically or by mail. This typically takes a few days. Some plans let you request a referral online through their member portal.

What happens if you see a specialist without a required referral

If your Medicare Advantage plan requires a referral and you see a specialist without one, you may face higher costs. Some plans will deny the claim entirely, meaning you pay the full bill. Others will cover the visit but charge you a higher copay or coinsurance than you would pay with a referral. A few plans will cover it anyway, but this is not may provide.

The specialist's office may also refuse to see you without a referral, or they may ask you to sign a form saying you understand you may have to pay out of pocket. To avoid this situation, always call your plan before scheduling a specialist appointment if you are unsure whether a referral is needed.

How to learn about your plan requires a referral

Start with your plan's member handbook. This document came with your plan materials or is available on your plan's website. Search for "referral" or "specialist" in the handbook. Most handbooks have a section that lists which types of doctors need referrals and which do not.

If the handbook does not answer your question, call your plan's customer service number. This number is on the back of your Medicare card. Tell the representative which specialist you want to see, and ask whether a referral is required. They can also tell you whether the specialist is in your plan's network and what your copay or coinsurance will be.

You can also ask your primary care doctor's office. They work with your plan regularly and know the referral rules. If you need a referral, they can often send it the same day you call.

Specialists who usually do not require referrals

Even in Medicare Advantage plans that require referrals for most specialists, certain doctors are often exempt. Gynecologists and obstetricians usually do not require referrals — you can see them directly. Optometrists and ophthalmologists (eye doctors) often do not require referrals either. Some plans also exempt mental health providers and dentists, though dental coverage is limited under Medicare.

These exemptions vary by plan, so do not assume. Check your handbook or call your plan to confirm before scheduling.

Emergency and urgent care do not require referrals

If you have a medical emergency or urgent problem that needs same-day or next-day care, you do not need a referral under any Medicare plan. Go to an urgent care clinic, emergency room, or call 911 if necessary. Your plan will cover emergency and urgent care even without a referral, though you may pay a copay or coinsurance.

After the emergency is over, if you need ongoing specialist care related to that emergency, ask the emergency room doctor or urgent care provider for a referral to a specialist. This protects you from unexpected bills later.

Frequently Asked Questions

Do I need a referral to see a physical therapist or occupational therapist?

Under Original Medicare, you do not need a referral to see a physical or occupational therapist, though Medicare does require that a doctor order the therapy. Under Medicare Advantage, most plans require a referral from your primary care doctor. Check your plan's handbook or call customer service to be sure.

What if my primary care doctor refuses to give me a referral?

If your doctor refuses to refer you to a specialist you believe you need, you can request a second opinion or file a complaint with your Medicare Advantage plan. You can also switch to Original Medicare during the annual enrollment period if you want the freedom to see specialists without referrals. Contact Medicare at 1-800-MEDICARE for information about your options.

Can I get a referral from an urgent care doctor or emergency room doctor?

Yes. If you see an urgent care provider or emergency room doctor and they think you need specialist care, they can send a referral to your plan. Ask them to do this before you leave, so the referral is in place when you try to schedule with the specialist.

Do I need a referral to see a specialist out of state?

If you have Original Medicare, you do not need a referral anywhere — you can see any Medicare-accepting doctor in any state. If you have Medicare Advantage and travel out of state, call your plan before scheduling. Some plans cover out-of-state specialists; others do not, or they require a referral even though the specialist is out of network.

How long does a referral last?

Referral validity varies by plan and by type of specialist. Some referrals are good for one visit; others cover multiple visits over several months. Ask your primary care doctor's office how long the referral is valid when they send it, or call your plan to ask.
