Part B Medicaid is a state program that pays for doctor visits and outpatient care

Part B Medicaid is a program run by individual states that covers medical services you receive outside a hospital — mainly visits to doctors' offices, clinics, and urgent care centers. It pays the provider directly, so you typically pay nothing or a small copay at the time of your visit. Part B is separate from Part A (hospital care) and Part D (prescription drugs), though many people have coverage under more than one part at the same time.

Each state designs its own Part B program, so what is covered and who can receive it varies by where you live. Some states cover more services than others, and income limits differ. If you already receive Medicaid in your state, you may already have Part B coverage without explore separately — your state determines which parts you receive based on your situation.

Key Takeaways

  • Part B Medicaid covers doctor office visits, preventive care, lab work, and outpatient services, with little or no cost to you at the time of service.
  • Each state runs its own Part B program with different income limits, covered services, and rules about who can receive it.
  • If you already have Medicaid in your state, you may already have Part B coverage — check your Medicaid card or contact your state's Medicaid office to confirm what parts you have.
  • Part B does not cover hospital stays (Part A), prescription drugs (Part D), or long-term care unless your state has added those services to its Part B program.

What Part B Medicaid covers

Part B typically covers visits to doctors, nurse practitioners, and physician assistants in office settings. It also covers preventive services like annual checkups, screenings, and vaccinations at no cost to you. Lab work and X-rays ordered by your doctor are usually covered, as are urgent care visits when you cannot reach your regular doctor.

Mental health and substance use treatment through outpatient clinics are covered in most states. Physical therapy, occupational therapy, and speech therapy ordered by a doctor are generally included. Some states also cover dental care, vision care, or hearing aids under Part B, though this varies widely — you will need to check your state's specific program.

What Part B does not cover includes hospital inpatient stays (that is Part A), prescription medications filled at a pharmacy (that is Part D), and routine dental or vision care in many states. Long-term care facilities and nursing home stays are not covered under Part B in most states.

How Part B differs from Part A and Part D

Part A Medicaid covers hospital inpatient care — when you are admitted and stay overnight. Part B covers outpatient services — when you go to a doctor's office or clinic and return home the same day. If you need surgery in a hospital, Part A pays for the hospital facility and stay, while Part B would cover your surgeon's fee if billed separately.

Part D covers prescription medications you pick up at a pharmacy or have delivered. Part B does not pay for these drugs. If your doctor prescribes a medication, you will use your Part D coverage (if you have it) to pay for it, not Part B. Some states bundle these programs together on one card, but they remain separate benefits with different rules.

You can have Part A without Part B, Part B without Part A, or both. Your state Medicaid program decides which parts you receive based on your income, age, disability status, and family situation. It is possible to have gaps — for example, Part A and Part B but not Part D — so always check what your specific Medicaid card covers.

How to learn about you have Part B coverage

The fastest way to confirm your Part B coverage is to look at your Medicaid card. The card lists which parts of Medicaid you have, usually shown as "Part A," "Part B," "Part D," or similar language. If your card does not clearly list the parts, or if you do not have a card, contact your state's Medicaid office directly.

Your state Medicaid office can be found through your state's health department website or by calling 211 (a free referral line). When you call, have your name, date of birth, and any Medicaid case number ready. They can tell you in minutes which parts you have and what services are covered under each one in your state.

If you do not currently have Medicaid but think you may be may be able to access, your state Medicaid office can also tell you what the income and resource limits are for your situation. They can explain the difference between Part B and other coverage options available to you.

Copays and costs under Part B

Most Part B Medicaid services are free or have very small copays — often $1 to $5 per visit. Preventive services like annual checkups and screenings are almost always free with no copay. The exact copay amount varies by state and sometimes by the type of service, so check your Medicaid materials or call your state office to learn what you will owe.

You are never responsible for the full cost of a covered service. Once your provider bills Medicaid and Part B pays its share, your responsibility ends (except for any copay). If a provider tries to bill you for the full cost of a covered service, contact your state Medicaid office — that is not allowed.

Some services may require prior authorization, meaning your doctor must ask Medicaid for permission before you receive the service. This does not cost you anything, but it can delay treatment by a few days. Your doctor's office usually handles this request, though you can also contact your state Medicaid office if you have questions about whether a service needs approval first.

Part B coverage varies significantly by state

Because each state designs its own Medicaid program, Part B coverage in one state may look very different from Part B in another. For example, some states cover dental care under Part B, while others do not. Some states cover vision care and eyeglasses, others do not. Income limits also differ — you might be may be able to access in one state but not in another based on the same income.

If you move to a different state, your Medicaid coverage may change. You will need to explore for Medicaid in your new state and may find that Part B covers different services or has different copays. Contact your new state's Medicaid office within 30 days of moving to understand what coverage you have there.

To learn exactly what Part B covers in your state, visit your state's Medicaid website or call your state Medicaid office. They can provide a detailed list of covered services, copay amounts, and any restrictions that explore to you.

When Part B is combined with other coverage

If you have both Medicaid and Medicare (a situation called "dual may be able to access"), Part B Medicaid acts as a secondary payer. Medicare pays first for covered services, and Medicaid Part B may cover costs that Medicare does not, such as copays or services Medicare does not cover. This can reduce your out-of-pocket costs significantly.

If you have Medicaid Part B and private insurance from an employer or spouse, Medicaid usually pays second. Your private insurance pays first, and Medicaid covers what it does not. You should always tell your doctor's office about all your coverage so they bill in the correct order.

Some people have Medicaid Part B and are also enrolled in a Medicaid managed care plan. In that case, the managed care plan coordinates your Part B benefits and may require you to use doctors within its network. Check your plan materials or call the plan's customer service line to understand how your Part B coverage works through your managed care plan.
