Insurance Denied Physical Therapy — How to Get It Covered

Your doctor or specialist recommended physical therapy. You've already been in pain, struggling to move, or recovering from surgery or injury. Physical therapy was supposed to be the path back to your life — and now your insurance company is saying no.

Physical therapy denials are among the most common and most reversible insurance denials out there. Insurers frequently call PT "not medically necessary," but they're often wrong — and appeal success rates for these denials are high when patients submit the right documentation.

Here's what to do.

Why Insurance Denies Physical Therapy

Understanding the denial reason is your first move. The most common reasons PT claims are denied:

"Not medically necessary" — This is the standard catch-all denial. The insurer's reviewer decided PT doesn't meet their clinical criteria, often without reviewing your full medical situation. This is the most beatable denial reason with the right documentation.

Visit limits exceeded — Many plans cap physical therapy at a set number of visits per year (20, 30, or 60 visits are common). Once you hit that cap, additional sessions are denied. This requires either a medical necessity exception or a separate appeal based on your ongoing clinical need.

Maintenance therapy exclusion — Insurers sometimes reclassify PT as "maintenance" care (keeping you stable rather than improving function) and deny it on those grounds. This is frequently challenged successfully — if your condition is improving, it's not maintenance.

Lack of progress — If your insurer's reviewer believes you're not making measurable improvement, they may deny continued sessions. Your therapist's notes are critical to counter this.

Step 1: Get Your Denial Letter and Identify the Exact Reason

Don't assume you know why they said no — read the denial letter carefully. The specific denial reason determines your appeal strategy.

If the letter is vague, call member services and ask them to provide the clinical basis for the denial in writing.

Step 2: Gather Documentation From Your Physical Therapist

Your PT is your most important ally here. Contact them immediately and request:

• Objective documentation of your condition — specific measurements of range of motion, strength deficits, functional limitations
• Treatment notes showing measurable progress toward functional goals (this counters the "maintenance" and "no progress" denial reasons)
• A clinical justification letter explaining why continued PT is medically necessary for your specific condition, with specific goals and expected timeline
• Documentation of what will happen if PT is discontinued — will you regress? Will you need surgery? Will you be unable to perform basic daily activities?

If your condition is severe enough that stopping PT would lead to worse outcomes or surgical intervention, that's a powerful argument. "Continued PT is necessary to avoid surgery" is very compelling.

Step 3: Get Your Referring Doctor Involved

Your prescribing physician — whether an orthopedist, neurologist, primary care doctor, or surgeon — should also submit a letter of medical necessity. This should include:

• Your diagnosis and the clinical basis for PT
• Why PT is the appropriate treatment (vs. alternatives)
• Specific functional goals the PT is working toward
• The expected duration of treatment
• What happens without continued PT

A letter from both your PT and your prescribing physician is significantly stronger than one letter alone.

Step 4: Address the Insurer's Specific Criteria

Request a copy of the clinical criteria the insurer used to deny your claim. These are typically based on standards from organizations like the Milliman Care Guidelines or InterQual. Your therapist or doctor can review these criteria and directly address each one in their letters.

When you argue the insurer's own language back to them — showing specifically how your case meets their stated criteria — appeals are far more likely to succeed.

Step 5: Write Your Appeal Letter

Your formal appeal letter should:

• Clearly state you are appealing and reference your claim/denial date
• Summarize the denial reason and why it's incorrect
• Reference the attached letters from your PT and doctor
• Cite specific objective measures of your ongoing need and progress
• If applicable, argue that maintenance care exclusions don't apply (because you are still making functional progress)
• If visit limits are the issue, argue for a medical necessity exception citing your specific clinical circumstances

Keep it focused and factual. Attach all supporting documentation.

Step 6: Escalate If Needed

If your internal appeal is denied, request an external independent review. PT denials based on "not medically necessary" are frequently overturned at external review when the patient has good clinical documentation. External reviewers tend to give more weight to treating providers' assessments than insurers do.

Also consider:

• Filing a state insurance commissioner complaint — especially if the denial appears to violate your plan terms
• Having your doctor's office advocate directly — some larger practices have case managers who push back on insurance decisions as a matter of routine

You Shouldn't Have to Suffer Without Care

Physical therapy isn't optional. For many conditions — post-surgical recovery, musculoskeletal injuries, neurological conditions, chronic pain — it's the difference between regaining function and permanent limitation. You deserve the care your medical team prescribed.

Appeal. Document everything. And don't let a desk reviewer who's never treated you override your doctor.
