HCPCS G0239: Group Respiratory Therapy for Muscle Strength and Endurance
HCPCS Level II code G0239 designates group therapeutic respiratory procedures aimed at improving respiratory function and strengthening respiratory muscles, and it includes patient monitoring. This group-based intervention is significant nationally as a component of pulmonary rehabilitation and respiratory care pathways for chronic and acute respiratory conditions. Group therapy can improve access and efficiency while delivering standardized therapeutic interventions to multiple patients simultaneously.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of billing considerations tied to HCPCS Level II code G0239, typical clinical contexts where the service is used, common co-occurring services for respiratory assessment and support, and how this code fits within pulmonary rehabilitation and outpatient respiratory care. The publication provides benchmarks and coding crosswalks to related respiratory procedures, highlights relevant clinical diagnoses commonly associated with the service, and summarizes payer coverage patterns and coding relationships that affect billing and claims processing nationally.

National Reimbursement Benchmarks
Nationally, Medicare’s mean rate of $15 sits below BUCA’s average commercial mean of $18.8, indicating commercial payers generally reimburse higher for G0239 than the Medicare baseline. Median values and upper percentiles further widen that gap for some commercial plans, with Cigna and Blue Cross Blue Shield showing especially elevated top-end rates compared with Medicare’s $15 median and $16 third quartile.
Dispersion analysis (P75 minus P25) shows Blue Cross Blue Shield and UnitedHealth Group with the widest interquartile ranges: BCBS range = $8.8 and UnitedHealth Group range = $11.8, signaling greater variability in negotiated commercial rates. The tightest spreads are Aetna (range = $9.4) and BUCA (range = $9.1), though BUCA’s spread is similar to Aetna’s; Cigna’s IQR = $7.1 sits in the middle.
