Summary & Overview
HCPCS G2169: Occupational Therapy Maintenance by Assistant, Home Health
HCPCS Level II code G2169 represents 15-minute units of occupational therapy maintenance performed by an occupational therapist assistant in the home health setting. This code captures non-skilled maintenance activities aimed at preserving a patient’s functional status and safety in the home. Nationally, G2169 matters for home health agencies, therapy providers, and payers because it distinguishes assistant-delivered maintenance services from skilled therapeutic interventions and carries implications for billing granularity and care planning. Key payers in typical national analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how G2169 is defined clinically and operationally, which payers commonly reimburse or recognize the code, and what to expect in terms of billing unitization and service setting. The publication provides benchmarks for utilization, summaries of payer policy positions where available, and clinical context around occupational therapy maintenance delivered by assistants in home health. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A homebound 78-year-old patient with a history of ischemic stroke and left-sided hemiparesis receives an occupational therapy maintenance program delivered by an occupational therapy assistant in the patient’s residence. The patient previously completed an active plan of care with an occupational therapist focused on improving functional upper-extremity use, transfers, adaptive self-care and fall prevention. After goals were met and the therapist transitioned the case to a maintenance program, the occupational therapy assistant provides recurring 15-minute sessions to reinforce safe, functional techniques for activities of daily living (ADLs), monitor status, implement adaptive equipment, and progress home safety strategies. Documentation includes the supervising occupational therapist’s established maintenance plan, the assistant’s interventions performed in each 15-minute unit, the patient’s response, any changes in functional status or safety risks, and communication with the supervising therapist about concerns or deviations from the plan.
