Physiotherapy (also called physical therapy) is covered by most health insurance plans in the United States, but the extent of that coverage varies widely depending on your plan type, your diagnosis, and whether your insurer considers the treatment medically necessary. The short answer is yes, you likely have some level of coverage, but understanding the details can save you from unexpected bills.
What “Medically Necessary” Means to Insurers
The single biggest factor determining whether your physical therapy gets covered is medical necessity. Insurers don’t just ask if you have a condition that could benefit from therapy. They ask whether your specific treatment requires the hands-on expertise of a licensed therapist, whether you’re making measurable progress, and whether the number of sessions you’re receiving is reasonable for your condition.
Medicare’s guidelines, which many private insurers model their own policies after, spell this out clearly. Your therapist’s documentation needs to show that your condition before, during, and after treatment demonstrates meaningful improvement. If you’ve plateaued or if the exercises you’re doing could be performed independently without a therapist’s guidance, coverage can be denied. Repetitive exercises that don’t require ongoing professional involvement are generally not considered skilled care, even if a therapist is in the room.
This means your therapist plays a direct role in keeping your coverage active. The more clearly they document why their expertise is needed at each visit, the stronger your claim. If your insurer denies continued sessions, it’s often because the documentation didn’t demonstrate that a trained professional’s skill was still required rather than a home exercise program.
How Coverage Differs by Plan Type
Your insurance plan structure affects both how you access physical therapy and what you pay for it.
HMO plans typically require a referral from your primary care doctor before you can see a physical therapist. Without that referral, the visit may not be covered at all. PPO plans are more flexible. You can often see a specialist, including a physical therapist, without a referral, though you’ll pay less if you stay within the plan’s network. EPO plans also skip the referral requirement for in-network specialists but won’t cover out-of-network providers.
If you have an HMO and your doctor hasn’t mentioned physical therapy, you’ll need to ask for that referral explicitly. With a PPO, you can usually book directly with a therapist’s office and confirm your coverage through their billing department before your first appointment.
Session Limits and Cost Caps
Under the Affordable Care Act, marketplace and employer-sponsored plans cannot impose annual dollar limits on essential health benefits, and rehabilitative services (including physical therapy) fall into that category. This means your insurer can’t cut you off at a fixed dollar amount per year for covered therapy.
However, many plans still limit the number of sessions per year or per condition. A common range is 20 to 60 visits annually, though some plans are more generous and others more restrictive. Your plan’s summary of benefits will list this number. Once you hit that cap, additional sessions come out of pocket unless your therapist successfully appeals for more based on medical necessity.
You’ll also still owe your standard cost-sharing: copays per visit (often $20 to $75), coinsurance after your deductible, or both. If you haven’t met your annual deductible yet, you may be paying the full negotiated rate for your first several sessions.
Medicare Coverage for Physical Therapy
Medicare Part B covers outpatient physical therapy with no hard cap on the number of sessions, but there is a financial threshold that triggers extra scrutiny. For 2026, that threshold is $2,480 for physical therapy and speech-language pathology services combined. Once your approved charges cross that line, your therapist must add a special modifier to each claim confirming that continued treatment is medically necessary and supported by documentation. Claims submitted above the threshold without that confirmation are automatically denied.
Below the threshold, Medicare pays 80% of the approved amount after your Part B deductible, and you’re responsible for the remaining 20%. If you have a Medigap (supplemental) policy, it may cover part or all of that 20%.
Workers’ Compensation and Auto Insurance
If your need for physical therapy stems from a workplace injury, workers’ compensation typically covers the full cost of treatment without copays or deductibles. The rules vary by state, and some states limit how many sessions are approved before requiring a review. Your employer’s workers’ comp insurer may also require you to see a therapist from an approved provider list.
Auto insurance works similarly for injuries from car accidents. If you live in a no-fault state, your personal injury protection (PIP) coverage pays for physical therapy regardless of who caused the accident, up to your policy’s limit. In at-fault states, the responsible driver’s liability insurance covers your treatment, though this can take longer to process.
Using an HSA or FSA for Out-of-Pocket Costs
Physical therapy qualifies as a reimbursable medical expense under IRS rules for both Health Savings Accounts and Flexible Spending Accounts. The IRS defines eligible medical expenses as costs for the “diagnosis, cure, mitigation, treatment, or prevention of disease,” and therapy received as medical treatment fits squarely within that definition. This applies to your copays, coinsurance, and any sessions your insurance doesn’t cover.
If you’re paying out of pocket for sessions beyond your plan’s limit or seeing an out-of-network therapist, using pre-tax HSA or FSA dollars effectively gives you a discount equal to your marginal tax rate, often 22% to 32% for most earners.
Telehealth Physical Therapy
Virtual physical therapy sessions have become more widely covered since the pandemic-era policy changes, and many of those flexibilities remain in place. Medicare covers telehealth therapy services through at least December 31, 2027, with no geographic restrictions. Patients can receive sessions at home, and in some cases, audio-only appointments are permitted when video isn’t feasible.
Private insurers have been slower to standardize telehealth PT coverage. Some cover virtual sessions at the same rate as in-person visits, while others limit coverage to initial evaluations or follow-up consultations. Check with your plan before scheduling a virtual appointment, because the reimbursement rules can differ from in-person visits even within the same policy.
How to Verify Your Coverage Before Starting
The most reliable way to avoid surprise costs is a quick call to your insurer before your first appointment. Ask these specific questions:
- Do I need a referral or prior authorization? Some plans require one, the other, or both.
- How many sessions are covered per year? Get the exact number and whether it resets on a calendar year or plan year basis.
- Is this therapist in-network? Out-of-network therapy can cost two to three times more.
- What’s my copay or coinsurance? This tells you your per-visit cost after the deductible is met.
- Does my deductible apply first? If you haven’t met it, your early sessions will cost significantly more.
Most physical therapy offices will also run a benefits check for you before your first visit. Give them your insurance information when you schedule, and they can confirm what your plan covers and what your estimated out-of-pocket cost will be per session.
