How to check what Medicare parts a patient has

You can find out whether a patient has Medicare Part A or Part B by looking at their Medicare card, calling Medicare directly, or asking the patient themselves. The card shows which parts are active. If you do not have the card in front of you, Medicare's phone line can confirm coverage in minutes. The fastest route depends on whether you are in the patient's home, at an office, or calling from a distance.

Part A covers hospital stays, skilled nursing care, and hospice. Part B covers doctor visits, outpatient care, and medical equipment. A patient can have one, both, or neither — and knowing which parts they carry changes what you bill and what the patient owes out of pocket.

Key Takeaways

  • The Medicare card itself shows which parts are active — look for "Hospital Insurance (Part A)" and "Medical Insurance (Part B)" with effective dates.
  • You can call Medicare at 1-800-MEDICARE (1-800-633-4227) with the patient's name and Social Security number to confirm coverage in real time.
  • If the patient is in front of you, asking them directly is often fastest — most people know whether they pay a monthly premium for Part B.
  • Online portals like MyMedicare.gov let you check a patient's coverage if you have their login credentials or power of attorney.
  • Coverage dates matter: a patient may have had Part A for years but enrolled in Part B only recently, or vice versa.

Reading the Medicare card to identify parts

The Medicare card lists each part separately with an effective date. Look for two sections: one labeled "Hospital Insurance (Part A)" and one labeled "Medical Insurance (Part B)." If a part is listed with a date, the patient has that coverage as of that date. If a part is not listed at all, the patient does not have it.

The card also shows the patient's Medicare number (different from their Social Security number) and the claim number used for billing. The back of the card may list a group number if the patient is covered through a Medicare Advantage plan or other supplemental coverage, which affects how you submit claims.

Newer Medicare cards no longer show the patient's full Social Security number for security reasons — they show only the last four digits. This is normal and does not affect your ability to verify coverage.

Calling Medicare to confirm coverage

Call Medicare at 1-800-MEDICARE (1-800-633-4227) and have the patient's name, date of birth, and Social Security number ready. A representative can tell you within minutes which parts the patient has, when coverage started, and whether there are any gaps or pending changes.

Medicare's phone lines are open Monday through Friday, 8 a.m. to 8 p.m. Eastern time, and Saturday 8 a.m. to 4 p.m. Eastern time. Wait times are usually shorter early in the morning or mid-week. If you call on behalf of a patient, you may need written authorization or power of attorney depending on what information you are requesting.

When you call, write down the representative's name, the date and time of the call, and what they told you. This creates a record if there is a billing dispute later.

Asking the patient directly

Many patients know whether they pay a monthly premium for Part B — if they do, they have Part B. Part A is usually automatic for people 65 and older who receive Social Security, so most patients have it unless they actively turned it down or are not yet may be able to access.

Ask the patient: "Do you pay a monthly premium for your Medicare?" If yes, they have Part B. Then ask: "Do you have hospital coverage through Medicare?" If yes, they have Part A. This is not a substitute for checking the card or calling Medicare, but it is a quick starting point and often correct.

Be aware that some patients are confused about their own coverage or may have recently made changes they do not fully understand. Always verify with the card or a call to Medicare before billing.

Using online portals and records

If you work in a medical office or hospital, your billing system may already have the patient's Medicare information on file from a previous visit. Check the patient record first — it often shows which parts are active and when coverage started.

MyMedicare.gov is Medicare's official patient portal. If you have the patient's login information or a signed power of attorney, you can log in and view their coverage details directly. The portal shows Part A and Part B status, effective dates, and any changes pending.

Some electronic health record systems pull Medicare data automatically when you enter a patient's Medicare number. If your system has this feature, run a real-time may be able to access check — it takes seconds and is often more current than information in the paper chart.

What to do if coverage information is unclear or missing

If the patient's card is damaged, lost, or outdated, do not guess. Call Medicare or ask the patient to call and request a replacement card — it arrives in about two weeks. In the meantime, use the Medicare number on any paperwork the patient has (an explanation of benefits letter, a previous bill, or a hospital discharge summary) to verify coverage by phone.

If the patient says they are not sure whether they have Part A or Part B, or if they recently turned 65 or made changes to their coverage, call Medicare to confirm. Do not assume Part A is automatic — some people delay enrollment and lose the automatic window, which can create coverage gaps.

If you are billing and the claim is rejected because of a coverage mismatch, the rejection notice will tell you which part Medicare says the patient does not have. Use that notice to follow up with the patient and correct the record before resubmitting.

Frequently Asked Questions

Can a patient have Part B without Part A?

Yes, though it is uncommon. Some people delay Part A enrollment but enroll in Part B early. Others have Part A through a former employer and Part B through individual enrollment. Always check the card rather than assuming both parts are present.

What if the patient's Medicare card shows a date that has already passed?

An old effective date does not mean coverage has ended — it means that is when coverage started. As long as the part is listed on the card, it is still active. If you are unsure, call Medicare to confirm the coverage is current.

Does a Medicare Advantage plan replace Part A and Part B?

No. Medicare Advantage is an alternative way to receive Part A and Part B benefits through a private insurer. The patient still has Part A and Part B — they are just delivered through the Advantage plan instead of original Medicare. The card will note the Advantage plan name.

How do I verify coverage if the patient is unconscious or unable to communicate?

Call Medicare with the patient's name, date of birth, and Social Security number. You do not need the patient's permission to confirm coverage for billing purposes. If you need to make medical decisions on the patient's behalf, you will need a health care power of attorney or legal guardianship.

What if Medicare says the patient has Part A but the patient says they do not want it?

The patient can decline Part A coverage, but they must do so in writing with Medicare. Until they submit a formal decline, Medicare considers them enrolled. If the patient wants to turn down Part A, direct them to call Medicare or visit MyMedicare.gov to submit a declination form.
