Summary & Overview
HCPCS G8852: Positive Airway Pressure Therapy Prescribed
HCPCS Level II code G8852 denotes that positive airway pressure (PAP) therapy was prescribed. This designation is used in claims to indicate the clinical decision to initiate PAP therapy, commonly associated with management of sleep-disordered breathing and other respiratory insufficiencies. Nationally, clear documentation of PAP prescriptions supports appropriate patient access to durable medical equipment and outpatient respiratory care pathways.
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 code’s clinical meaning, typical sites of service (outpatient clinics, sleep medicine centers, and home/DME settings), and which payers commonly adjudicate claims with this code.
The publication will present benchmarking and utilization context, common billing considerations for encounters that generate G8852, and any relevant policy or coverage notes where available. It will also summarize where data are present and indicate when input data are not available. This resource is intended for clinical billing staff, compliance teams, and payers seeking a national perspective on documentation and billing practices associated with PAP therapy prescriptions.

Clinical & Coding Specifications
Clinical Context
A 54-year-old patient with suspected obstructive sleep apnea presents to a sleep medicine clinic after an overnight polysomnography that demonstrates moderate to severe sleep-disordered breathing. The treating pulmonologist or sleep medicine physician reviews the sleep study report, documents the diagnosis, performs a clinical evaluation including assessment of comorbidities (hypertension, daytime somnolence, cardiovascular risk), and prescribes positive airway pressure therapy. The prescription specifies device type (CPAP, APAP, or BiPAP), pressure settings or titration instructions, and mask interface. The clinical workflow includes patient education on device use, arrangement for durable medical equipment (DME) delivery or in-clinic setup, initiation of therapy with mask fitting and troubleshooting, and scheduling of follow-up for adherence monitoring and troubleshooting remote device data. Documentation in the medical record includes the sleep study report, a written prescription for positive airway pressure therapy, medical necessity rationale, and plan for follow-up and adherence assessment.
