How to Find Out Which Medicare Part Your Patient Is On

How to check a patient's Medicare coverage type

You can find out whether a patient is on Medicare Part A or Part B by looking at their Medicare card, calling Medicare directly, or checking their online account. The fastest way is the card itself — it clearly states which parts are active. If you need to verify coverage for billing or care planning, Medicare's phone line and the patient's own online account both give you the same information in minutes.

The reason this matters: Part A covers hospital stays, skilled nursing, and hospice. Part B covers doctor visits, outpatient care, and some equipment. A patient might have one, both, or neither. Knowing which parts are active tells you what Medicare will pay for and what the patient owes out of pocket.

Key Takeaways

The Medicare card itself shows which parts (A, B, D) the patient has active, printed right on the front and back.
Medicare.gov's "My Medicare" portal lets patients and their authorized representatives check coverage details online anytime.
Calling 1-800-MEDICARE (1-800-633-4227) confirms coverage in real time and takes about 10 minutes.
If a patient lost their card or it is unclear, the Social Security number and date of birth are all Medicare needs to pull up the account.

Reading the Medicare card

The front of the card shows the patient's name, Medicare number, and the parts they have. Look for the words "HOSPITAL (PART A)" and "MEDICAL (PART B)" — if they appear, that part is active. The card also shows the effective date for each part. Some cards list Part D (prescription drug coverage) as well.

The back of the card repeats this information and includes the customer service phone number. If the card is worn or the print is faded, you can request a replacement by calling 1-800-MEDICARE or visiting Medicare.gov. A new card arrives in about two weeks.

Using the patient's online Medicare account

Patients can log into Medicare.gov using their username and password to see their coverage details. This account, called "My Medicare," shows which parts are active, the effective dates, and any recent changes to coverage. The patient can also read or print a copy of their coverage information from this portal.

If the patient has not set up an online account, they can create one at Medicare.gov in about 10 minutes using their email, Social Security number, and date of birth. If you are a caregiver or healthcare provider with the patient's permission, you may be able to access this information through a power of attorney or authorized representative status — ask the patient to check their account settings for this option.

Calling Medicare directly

Call 1-800-MEDICARE (1-800-633-4227) to speak with a representative who can confirm which parts the patient has. Have the patient's Medicare number or Social Security number and date of birth ready. The wait time is usually 10 to 20 minutes, and representatives are available Monday through Friday, 8 a.m. to 8 p.m. Eastern time, and Saturday 8 a.m. to 4 p.m. Eastern time.

If you are calling on behalf of a patient, let the representative know. They may ask you to have the patient on the line or to provide written authorization before releasing details. This is a privacy protection, so have the patient's consent before you call.

What the difference between Part A and Part B means for care

Part A covers inpatient hospital care, skilled nursing facility stays (up to 100 days per benefit period), home health services, and hospice. Part B covers doctor office visits, preventive care, outpatient surgery, lab work, imaging, and durable medical equipment like wheelchairs or oxygen. Many seniors have both parts, but some have only Part A (usually those who delayed Part B enrollment) or only Part B (rare, but possible if they turned down Part A).

If a patient has only Part A and needs a doctor visit, they will owe the full cost unless they have other coverage. If they have only Part B and need a hospital stay, they will owe the full inpatient cost. This is why confirming coverage before scheduling care or billing prevents surprises for both the patient and your practice.

When coverage information changes

A patient's Medicare coverage can change if they enroll in or drop a plan, if they turn 65 and become newly may be able to access, or if they move to a different state. Changes usually take effect on the first of the month following the enrollment request, though some changes are when ready. The patient receives a notice in the mail when coverage changes.

If you see a discrepancy between what the patient told you and what Medicare shows, ask the patient to check their most recent notice from Medicare or log into their online account. If the patient believes coverage was changed by mistake, they can call 1-800-MEDICARE to request a review.

Frequently Asked Questions

Can a patient have Part B without Part A?

Yes, though it is uncommon. This usually happens when someone delayed enrolling in Part A at 65 and enrolled in Part B instead. They can enroll in Part A later, but they may owe a penalty. Part B alone means hospital stays are not covered by Medicare.

What if the patient's card says "Part A" but not "Part B"?

The patient has hospital coverage but not doctor visit coverage. They will need to enroll in Part B if they want Medicare to cover office visits and outpatient care. Outside the initial enrollment window, they can enroll during the General Enrollment Period (January 1 to March 31 each year), though a late enrollment penalty may explore.

How do I know if a patient has Part D coverage?

The Medicare card lists Part D if the patient has prescription drug coverage. You can also ask the patient directly or check their online account. If they do not have Part D and want it, they can enroll during the Annual Enrollment Period (October 15 to December 7 each year).

What if the patient does not have their card and cannot remember their Medicare number?

Call 1-800-MEDICARE with the patient's Social Security number and date of birth. The representative can pull up the account and tell you which parts are active. You can also ask the patient to check their online account if they have one set up.

Does checking coverage information count as verifying may be able to access?

No. Checking which parts a patient has is different from verifying that they are covered for a specific service. A patient might have Part B but still owe a copay, coinsurance, or deductible. Always check the patient's coverage details and any prior authorization requirements before scheduling care.
