Summary & Overview
HCPCS S9061: Home Aerosolized Drug Therapy, Per Diem
HCPCS Level II code S9061 denotes per diem administrative and professional pharmacy services for home-based aerosolized drug therapy, such as pentamidine, including care coordination and necessary supplies and equipment (with drugs and nursing visits billed separately). This code matters nationally as home administration of aerosolized medications expands care options for patients who require inhaled prophylaxis or treatment outside institutional settings, affecting pharmacy services, durable supplies, and care coordination workflows.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical service and site of care implications, common billing considerations, and what to expect in payer coverage policies nationally. The publication outlines benchmarks and typical service components tied to S9061, highlights policy and coding context relevant to pharmacy and home health administrators, and summarizes operational factors for home-delivered aerosolized therapies.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with HIV-associated Pneumocystis jirovecii pneumonia (PJP) or another opportunistic pulmonary infection who requires prophylactic or therapeutic aerosolized pentamidine administered at home. The patient has difficulty tolerating or accessing clinic-based nebulization because of mobility limitations, immunosuppression, or transportation barriers. A home infusion or home respiratory therapy agency coordinates care: the pharmacy dispenses and ships the aerosolized medication and necessary disposables, a respiratory therapist or licensed practical nurse performs set-up and monitors initial administrations, and the patient or caregiver is trained on device use and infection-control precautions. The per-diem billing for S9061 covers administrative services, professional pharmacy services, care coordination, and supplies/equipment (drugs and nursing visits are coded separately). Typical workflow: referral from infectious disease or pulmonology → pharmacy verification and prior authorization → delivery of medication plus nebulizer/mask and instructions → home visit for first administration and education → scheduled subsequent administrations or standing orders for nursing visits if required. Documentation includes indication, informed consent, medication dosing and lot numbers, device and supply inventory, training/education provided, monitoring of adverse reactions, and coordination notes with prescribing clinician.
