Occupational Therapy Insurance Denied? How to Appeal the Decision

Occupational therapy (OT) helps people regain or maintain the ability to perform the meaningful activities of daily life — dressing, grooming, cooking, working, parenting. When an insurer denies OT, it is telling a patient that the work of rebuilding functional independence is not worth paying for. These denials are frequently wrong, and they are appealable.

Why Occupational Therapy Claims Get Denied

"Maintenance therapy" exclusion. Insurers routinely deny OT once a patient's documented progress slows, reclassifying further treatment as "maintenance" rather than "skilled care." Under the landmark 2013 Jimmo v. Sebelius settlement with Medicare, coverage cannot be denied solely because a patient is not improving — if skilled care is needed to prevent decline or maintain function, it is covered. Many private insurers follow similar reasoning, and invoking Jimmo in a private appeal can be persuasive.

Visit limit exhaustion. Most plans cap OT at a fixed number of visits per year, often combined with physical therapy. When medically necessary treatment extends beyond the cap, you can appeal on medical necessity grounds and request an exception.

ADL documentation insufficient. Denials often occur because the treating OT's documentation does not quantify functional deficits adequately. Vague notes like "patient working on fine motor skills" do not support medical necessity the way specific functional outcome measures do — FIM scores, COPM (Canadian Occupational Performance Measure), box-and-block scores, or DASH (Disabilities of the Arm, Shoulder, and Hand) questionnaires.

"Custodial care" reclassification. Insurers sometimes reclassify OT services as custodial when provided in a home or long-term care setting. Custodial care is typically excluded from coverage. The distinction between skilled OT and custodial assistance rests on whether a licensed therapist's training is needed to perform the service — and in most cases, it is.

Sensory processing in adults. Insurance coverage for sensory integration therapy in adult patients with autism, PTSD-related sensory dysregulation, or acquired neurological conditions is inconsistent. Denials often cite lack of evidence, but emerging research and functional outcome data support this intervention.

Clinical Indications That Strongly Support OT Coverage

Post-surgical rehabilitation. After hand surgery, joint replacement, mastectomy, or spinal surgery, OT is medically necessary for restoring functional range of motion and ADL independence. Coverage for this indication is broadly supported.

Neurological conditions. Stroke, TBI, multiple sclerosis, Parkinson's disease, and spinal cord injury all generate strong OT coverage claims. Functional improvement goals — regaining the ability to dress independently, return to driving, resume household tasks — are concrete, measurable, and defensible.

Work hardening and work conditioning. For injured workers returning to physically demanding employment, work hardening programs (which include OT and PT components) are medically necessary. Document job-specific functional demands and compare them to current patient capacity.

Hand therapy. OT is the primary discipline for post-fracture, post-tendon repair, and post-nerve repair hand rehabilitation. Certified Hand Therapists (CHTs) are often OTs. Documentation should include grip strength measurements, range of motion measurements, and functional hand use assessments.

Burn rehabilitation. Scar management, splinting to prevent contracture, and ADL retraining after burns require skilled OT. The clinical necessity here is unambiguous.

Pediatric OT (when billed under medical rather than educational benefit). For children with fine motor delays, feeding disorders, or sensory processing disorders, OT can be covered under the medical benefit when the diagnosis is a recognized medical condition. This is separate from school-based OT under IDEA.

What Your Appeal Should Include

Your appeal letter should translate the clinical record into functional terms the reviewer can evaluate. Include:

1. Standardized functional outcome scores from the initial evaluation and recent visits showing baseline and current status.
2. Specific treatment goals with measurable functional milestones (e.g., "patient will independently don/doff upper extremity clothing within 6 weeks").
3. Documentation that skilled OT — not a home health aide or family caregiver — is required to perform the tasks being addressed.
4. Physician or specialist co-signature supporting the continuing medical necessity of treatment.
5. Reference to AOTA (American Occupational Therapy Association) practice guidelines for the relevant condition.

If the denial cites maintenance care, explicitly address the Jimmo standard and state that skilled OT is required to prevent deterioration in a functionally dependent patient.
