Insurance Denied Physical Therapy Visits? Here's How to Appeal

Physical therapy visit limits are one of the most common sources of insurance disputes. When your insurer says you've hit your annual cap — or that your PT is no longer medically necessary — your recovery can come to a sudden halt. But visit limits can be appealed, and maintenance therapy is protected by federal court precedent. Here is how to fight back effectively.

Why Insurers Deny Physical Therapy Visits

• Annual visit cap reached: The plan has a fixed number of PT visits per year (commonly 20, 30, or 60)
• Plateau in progress: The insurer argues that since you are no longer making measurable improvement, PT is no longer medically necessary
• Lack of functional goals: The insurer argues the therapy is for general wellness, not treatment of a specific condition
• Prior Authorization Denied: How to Appeal" class="auto-link">Prior authorization not renewed: PA was approved for an initial period and the renewal was denied
• Coding mismatch: Wrong CPT code or mismatch between the procedure and diagnosis

Common denial codes: CO-119 (benefit maximum reached), CO-50 (not medically necessary), CO-197 (prior authorization absent or exceeded).

How to Appeal a Physical Therapy Denial

Step 1: Identify the Specific Denial Basis

Determine whether the denial is for visit cap exhaustion, "not medically necessary," improvement standard, or prior authorization. Each requires a targeted response.

Step 2: Invoke Jimmo v. Sebelius for Maintenance Therapy

The landmark case Jimmo v. Sebelius (settled 2013, clarification 2017) established that the improvement standard is not the correct standard for determining Medicare coverage of skilled care. Medicare covers skilled therapy — including PT — when the therapy is necessary to maintain a patient's condition or prevent decline, not only when the patient is improving. This principle is codified in the Medicare Benefit Policy Manual, Chapter 15, and has influenced commercial insurance interpretation of maintenance therapy. If your PT is needed to maintain your current level of function, prevent deterioration, or manage a chronic condition, cite Jimmo v. Sebelius directly.

Step 3: Document Functional Goals Under APTA Standards

The American Physical Therapy Association (APTA) emphasizes specific, measurable functional goals tied to activities of daily living and participation in work, family, and community roles. Strong functional goals for an appeal include: "Patient will ambulate 300 feet without assistive device to navigate home safely," "Patient will achieve 120 degrees of shoulder flexion to perform overhead ADLs," and "Patient will reduce fall risk score from high to moderate to safely live independently." Work with your therapist to ensure treatment notes document baseline measurements, current measurements, and progress toward these specific goals.

Step 4: Request a Medical Necessity Exception for Visit Cap Denials

Most plans have an exception process for visit limits when additional visits are medically necessary. Your PT and referring physician must document the specific diagnosis and remaining functional deficits, why additional visits are clinically indicated, expected functional outcome with continued treatment, and consequences of stopping — increased fall risk, return of pain, need for more invasive intervention.

If your plan has a mental health visit limit and applies it differently from the PT limit — for example, mental health has exceptions but PT does not — this may be a MHPAEA parity issue under 29 U.S.C. § 1185a. Some states also prohibit or limit visit caps for PT under certain conditions.

Step 6: Request Peer-to-Peer Review

Your treating physician can request a peer-to-peer call with the insurer's medical reviewer, presenting objective functional measurements, APTA and condition-specific clinical guidelines, and the consequence of discontinuing PT prematurely.

What to Include in Your Appeal

• Physical therapist's progress notes with standardized outcome measures (DASH for upper extremity, LEFS for lower extremity, Berg Balance Scale) and specific measurable goals
• Jimmo v. Sebelius citation and CMS Medicare Benefit Policy Manual, Chapter 15 if improvement standard was applied
• Physician's letter of medical necessity with specific clinical rationale for continued PT beyond the plan limit
• Objective measurements including ROM, MMT grades, balance assessments, and gait analysis with baseline and current values
• Consequence of cessation documentation — what is expected to happen clinically if PT stops prematurely
