Why physical therapy coverage is its own topic
Physical therapy sits in an unusual spot. It is ordinary medical care, yet many plans manage it more tightly than a doctor visit. A course of treatment can involve many sessions over weeks or months, which means the total cost can add up even when each visit looks small. Insurers often respond with limits, approval requirements or both.
Physical therapy may be covered when it is ordered to help you recover from an injury, surgery or illness, or to improve function that has been lost. Plans typically look at whether the care is expected to produce meaningful improvement, a point tied to the idea of medical necessity. Wellness-style sessions that are not tied to a medical need are generally not covered.
Visit limits
The feature that surprises people most is the cap on visits. Some plans set a maximum number of therapy visits per year, and the number varies from plan to plan. Several points are worth knowing:
- The limit may apply to physical therapy alone, or to physical, occupational and speech therapy combined.
- Chiropractic care and other rehabilitative services may share the same pool of visits under some plans.
- The limit may count each visit, whatever its length, or may be based on units of time.
- The count usually resets at the start of the plan year, which may be January or a different month depending on the plan.
- Some plans allow additional visits if your therapist documents that further care is needed.
Here is a hypothetical example. Suppose a plan covers 20 therapy visits per year and your therapist recommends 24 sessions after surgery. You would typically be responsible for the cost of the last four unless the plan approves an extension, or unless the new plan year begins before they take place. Check the actual number in your plan, since the figure above is only an illustration.
The visit cap and your cost sharing are separate things. Even visits within the cap usually come with a copay or coinsurance, or they may apply to your deductible first. The general difference between a copay and coinsurance is covered in material on copay and coinsurance, and the total you can be asked to pay in a year is limited by your out-of-pocket maximum, though costs for services beyond a benefit limit may not count toward that maximum. Your plan documents should say.
Referral and authorization rules
Two different requirements often get confused.
A referral is a recommendation from your primary doctor to see a particular provider. Some plans, particularly those that resemble health maintenance organizations, require one before you see a therapist. Others let you book directly. Whether a referral is needed may depend on the plan, not on the law alone, so confirm it. The general idea of specialist referrals applies here.
A prescription or order is a separate matter. Some plans want a written order from a physician stating the diagnosis and the planned treatment, even if no formal referral is required.
Prior authorization is a third layer. Some plans require the therapist or the doctor to get approval from the insurer, either before treatment begins or after a certain number of visits. If approval is required and was not obtained, the claim can be denied, and you may be asked to pay. Many therapy offices handle this paperwork, but it is reasonable to ask whether they have done so and to keep your own notes.
Network matters
Physical therapy is delivered by a wide range of clinics, including independent practices, hospital-based outpatient departments and clinics tied to a physician’s office. Whether a clinic is in your network can change what you pay considerably. Seeing an out-of-network provider can mean higher cost sharing, a separate and higher deductible, or no coverage at all, depending on the plan. A hospital-based outpatient setting may also bill differently than a stand-alone clinic.
Before your first session, check that both the clinic and the individual therapist are in network. Some practices employ both in-network and out-of-network therapists.
Questions to ask before you start
Calling your insurer before treatment can prevent a good deal of confusion. Useful questions include:
- Is physical therapy covered under my plan, and for what conditions?
- Is there a limit on the number of visits per year? Do other therapies share that limit?
- Do I need a referral, a physician order, or prior authorization?
- What will I pay per visit: a copay, coinsurance, or the full allowed amount until I meet my deductible?
- Is this clinic in network?
- Does the visit limit reset at the start of the calendar year or on another date?
Write down the date, who you spoke with and what they said. If a dispute arises later, notes help.
Other situations to be aware of
After surgery or an accident. Therapy after a procedure may be bundled with that care or billed separately. Surgery coverage rules and rehabilitation rules are not always the same, and some plans treat post-surgical therapy more generously than therapy for ongoing conditions.
Chronic conditions. Plans sometimes treat therapy for a long-standing problem differently from therapy that follows a recent injury. Some limit coverage to care expected to produce improvement, as opposed to care meant only to maintain function. Rules on this point vary a great deal.
Telehealth and home visits. Some therapy can be delivered by video or at home, and whether it is covered depends on the plan.
Using a health account. If you have a health savings account or a flexible spending account, you may be able to pay for therapy you must cover yourself. Account rules differ, so check eligibility.
If a claim is denied
A denial may come from reaching the visit cap, missing an authorization, going to an out-of-network clinic, or the insurer’s view that the therapy is not medically necessary. Start by reading the denial letter carefully to see the stated reason. A mistake in coding or paperwork can often be fixed by the provider’s office. If the denial stands and you disagree, a claim appeal is generally available, and your therapist or doctor may be able to provide supporting notes. Outcomes are never guaranteed, but a clear record of your treatment plan helps.
Keep in mind
Therapy coverage depends heavily on plan details: the yearly visit count, referral and authorization rules, network status and your cost sharing. Learning those details before the first appointment is usually easier than sorting out a bill after the fact. Your insurer and your health care providers can answer questions specific to your situation.
