Occupational Therapy Denied by Insurance? How to Appeal

Occupational therapy (OT) helps people regain or develop the skills needed for daily activities — from self-care and work to sensory processing and fine motor skills. Despite its proven benefits, OT is frequently denied by insurers, especially after a certain number of sessions. Here's how to appeal.

Why OT Is Denied

"Not Medically Necessary"

The most common denial. Insurers may claim:

• The patient can perform ADLs adequately without OT
• No skilled OT is required (the task could be done by a caregiver)
• No functional goals remain achievable

Session Limit Exhaustion

Many plans limit OT to 20–60 visits per year. After the limit is reached, coverage ends — even if therapeutic goals haven't been achieved.

"Maintenance Therapy" Denial

Insurers sometimes deny OT once the patient plateaus, claiming further therapy is "maintenance" rather than treatment. This is frequently incorrect and legally contestable under the Jimmo v. Sebelius standard (for Medicare patients).

Children's OT: "Educational" Denial

For children, insurers sometimes claim OT is "educational" (should be provided through school) rather than medical — shifting responsibility to the school district. This may be inappropriate when the OT is for medical conditions (sensory processing disorder, autism, fine motor delays) that extend beyond the school setting.

Evidence Base for OT

OT is supported by extensive clinical evidence:

• Cochrane Reviews: OT improves functional outcomes in stroke, dementia, upper limb injury, chronic pain, and mental health conditions
• AOTA (American Occupational Therapy Association) Evidence-Based Practice summaries support OT for specific conditions
• AAP (American Academy of Pediatrics): Recommends OT for autism spectrum disorder, developmental coordination disorder, and sensory processing issues

Building Your OT Appeal

For Adults

1. Functional Assessment Documentation Your OT should complete and include:

• Functional Independence Measure (FIM): Measures independence in 18 ADL activities (1-7 scale; 1 = total assistance, 7 = complete independence)
• Canadian Occupational Performance Measure (COPM): Patient-centered assessment of occupational performance
• Barthel Index: 10-item ADL measure
• Wolf Motor Function Test (for upper extremity): Objective fine motor/upper limb function

Document specific deficits: "Patient scores 2/7 (maximal assistance) on FIM dressing subscale. Without OT, patient cannot dress independently or safely."

2. Functional Goals (SMART) Your OT must document specific, measurable goals with expected timelines:

• "Patient will increase dressing FIM score from 2 to 5 (modified independence) within 8 sessions"
• "Patient will demonstrate safe home fall prevention strategies with 90% accuracy within 6 sessions"
• "Patient will return to driving with compensatory techniques within 12 sessions"

3. Medical Diagnosis as OT Driver Connect the OT need to a specific medical diagnosis:

• Post-stroke rehabilitation (ICD-10: Z87.39)
• Traumatic brain injury (S09.90)
• Upper extremity fracture/surgery recovery
• Chronic pain syndrome (G89.29)
• Multiple sclerosis (G35)
• Rheumatoid arthritis (M06.9) — joint protection, adaptive equipment
• Dementia (F00-F03)

For Children (Pediatric OT)

1. Distinguish Medical from Educational OT Medical OT (covered by health insurance) addresses conditions that affect the child's health, safety, and participation in daily activities beyond the school setting:

• Autism spectrum disorder (ASD) affecting self-care, sensory regulation, safety
• Developmental coordination disorder (DCD) affecting daily activities at home
• Sensory processing disorder (SPD) causing distress and functional impairment across all settings
• Fine motor delays affecting eating, dressing, bathing

School-based OT (provided under IDEA by the school district) focuses on educational participation. Both can be appropriate simultaneously — a child may receive school OT AND medical OT.

2. Document Multi-Setting Impairment Emphasize that the child's deficits affect functioning outside the school setting:

• Inability to self-care (bathing, dressing, eating) at home
• Safety risks at home due to sensory or motor issues
• Social participation limitations beyond school

3. Pediatric Assessment Tools

• Beery VMI (Visual-Motor Integration): Measures fine motor and visual motor skills
• Sensory Profile 2: Documents sensory processing patterns
• PDMS-2 (Peabody Developmental Motor Scales): Gross and fine motor assessment
• MABC-2 (Movement Assessment Battery for Children): Motor skill assessment

The Jimmo v. Sebelius Argument for Medicare Patients

For Medicare patients denied OT as "maintenance":

• Jimmo v. Sebelius (2013): Medicare must cover skilled care needed to maintain function or prevent decline, even without improvement potential
• OT to maintain safe ADL performance, prevent falls, or prevent further functional loss is covered under Jimmo
• Cite this explicitly: "The denial citing 'no improvement expected' violates the 2013 Jimmo settlement. Medicare covers skilled OT to maintain [specific function] and prevent further decline."

Fight Back With ClaimBack

ClaimBack generates OT appeal letters that cite Jimmo v. Sebelius, AOTA evidence-based practice guidelines, and functional assessment scores from your therapist's documentation.
