Medicaid does cover physical therapy, but the specifics depend heavily on your state, your age, and whether your condition meets medical necessity requirements. For children under 21, physical therapy is a mandatory benefit in every state. For adults, it’s classified as an optional benefit, meaning each state decides whether to include it in its coverage plan, and most do with varying limitations.
Coverage for Children Is Stronger
Children and adolescents enrolled in Medicaid receive physical therapy through a federal benefit called Early and Periodic Screening, Diagnostic, and Treatment (EPSDT). Under EPSDT, states are required to cover physical therapy when it’s medically necessary to correct or improve a diagnosed condition. This isn’t limited to recovery from injuries. Physical therapy for children is also covered when it serves a maintenance purpose, helping a child preserve function or prevent decline.
One of the most important protections under EPSDT is that states cannot impose hard visit limits on children’s physical therapy. A state might set a standard number of approved visits per year, but if a child’s treatment team determines that additional sessions are medically necessary, those extra visits must be covered. This makes pediatric PT coverage significantly more generous than what adults typically receive.
Adult Coverage Varies by State
For adults 21 and older, physical therapy is an optional Medicaid benefit. The federal government does not require states to cover it, though most states choose to include some level of PT in their programs. The catch is that states have wide latitude to set their own rules around how many visits you can get, what conditions qualify, and whether you need prior authorization before starting treatment.
States commonly impose annual visit caps for adults. North Carolina, for example, limits certain outpatient provider visits to 22 per year (running from July 1 through June 30), with additional caps on specific provider types like chiropractors and podiatrists at 8 visits. Other states set their own numbers, and some use dollar-amount caps instead of visit counts. Unlike with children, these hard limits generally stand for adults. If you hit your cap, you’re responsible for any additional sessions unless your state has an exception process.
To find out exactly what your state covers, contact your state Medicaid office or check its website. Coverage details, visit limits, and eligible conditions can change from year to year.
Medical Necessity Is the Key Requirement
Regardless of your state, Medicaid only covers physical therapy that’s deemed medically necessary. This means your provider needs to document that therapy will lead to meaningful improvement in your condition or, in some cases, prevent your function from getting worse. Simply wanting physical therapy or requesting it for general wellness is not enough.
Your therapist’s documentation plays a central role. The medical record needs to clearly describe your condition before treatment begins, track your progress during therapy, and show that you’re benefiting in practical, measurable ways. For example, if you start treatment with significant weakness in your knee, your therapist would document your baseline strength and then show improvement at regular check-ins. If progress stalls or the treatment isn’t producing functional gains, continued coverage can be denied.
In many states, physical therapy must also be prescribed by your physician. Kansas Medicaid, for instance, requires that rehabilitation therapy services be prescribed by the attending physician and that the therapy be “rehabilitative and restorative in nature” following an acute illness, injury, or physical trauma. Other states have similar referral requirements, so you’ll typically need to start with your doctor rather than going directly to a physical therapist.
Prior Authorization and Managed Care
How you access physical therapy also depends on whether your Medicaid plan is fee-for-service or managed care. In a fee-for-service arrangement, the state Medicaid agency processes your claims directly, and you may need to get prior authorization (sometimes called precertification) before starting outpatient therapy. In Georgia’s fee-for-service program, for example, hospital outpatient therapy requires prior authorization with documentation of your acute condition and the date symptoms began. Initial decisions on authorization requests typically come within 10 business days.
If you’re enrolled in a Medicaid managed care plan (sometimes called a CMO or MCO), your managed care organization handles authorizations separately. The rules, paperwork, and timelines can differ from fee-for-service. Your managed care plan may also have its own network of approved physical therapy providers, and going out of network could mean your visits aren’t covered. Check with your plan before scheduling an appointment to avoid surprise bills.
What You’ll Pay Out of Pocket
Medicaid copayments for physical therapy are generally very low. Federal rules tie maximum allowable copayments to your family income. For non-institutional care like physician visits and physical therapy, copayments start at $4.00 for the lowest-income enrollees. States can set alternative cost-sharing amounts for people with incomes above the federal poverty level, but total out-of-pocket costs are capped at 5% of family income.
Some groups are exempt from copayments entirely, including children, pregnant women, and people in certain income brackets. If you’re asked to pay a copayment, a provider cannot refuse to see you if you can’t afford it. Medicaid rules prohibit denying services for inability to pay cost-sharing amounts.
How to Get Started
If you’re on Medicaid and think you need physical therapy, the typical path looks like this: schedule a visit with your primary care provider, discuss your symptoms and functional limitations, and ask for a referral to physical therapy. Your doctor’s referral and documentation of your condition form the foundation for Medicaid to approve coverage.
Before your first PT appointment, confirm with your Medicaid plan whether prior authorization is needed and whether the therapist you want to see is in-network. Ask about your state’s visit limits so you and your therapist can plan treatment accordingly. If you’re nearing your cap and still need care, your therapist can sometimes request additional visits by documenting ongoing medical necessity, though approval is not guaranteed for adults.
For parents of children on Medicaid, know that EPSDT protections give your child broader access than adults receive. If your child’s therapist recommends more sessions than a standard limit allows, those additional visits should be covered as long as the need is documented. If a request is denied, you have the right to appeal through your state’s Medicaid fair hearing process.
