Occupational Therapy Medical Billing Services

Why Occupational Therapy Billing Is Complex

Occupational therapy billing involves strict documentation rules, timed procedure coding, and ongoing payer scrutiny. Common billing challenges include:

Time-Based CPT Coding Requirements

Many occupational therapy services use timed CPT codes under the 8-minute rule. Incorrect time calculations, missing treatment minutes, or improper unit billing frequently result in denials and underpayments.

Therapy Modifiers & Compliance Rules

OT claims often require modifiers such as GO, KX, CQ, and 59 depending on the service type, therapy threshold status, and assistant involvement. Incorrect modifier usage can trigger claim rejections or compliance issues.

Plan of Care Documentation

Payers require signed plans of care, progress notes, re-certifications, and medical necessity documentation for continued therapy services. Missing documentation is one of the leading causes of therapy denials.

Authorization Management

Many insurance carriers require prior authorization for occupational therapy visits, especially for paediatric therapy, neurological rehabilitation, and long-term treatment plans. Missed or expired authorizations can lead to non-payment.

Multiple Discipline Coordination

Practices offering OT alongside physical therapy or speech therapy must carefully manage discipline-specific coding, modifiers, and billing limitations to avoid duplicate or bundled denials.
