HCPCS G0238: One-on-One Therapeutic Respiratory Procedure
HCPCS Level II code G0238 denotes one-on-one, face-to-face therapeutic procedures to improve respiratory function, billed in 15-minute increments, and includes monitoring. Nationally, this code is important for documenting individualized respiratory therapy services provided outside acute inpatient settings, particularly for patients with chronic lung disease or post-infectious respiratory impairment. Proper use of G0238 supports accurate service capture, care coordination, and appropriate claims processing for time-based respiratory interventions.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find an overview of clinical applicability and service settings, comparisons to related respiratory therapy codes, and common administrative considerations tied to billing and claims processing. The publication outlines typical use cases, the relationship of G0238 to session-based pulmonary rehabilitation services, and coding distinctions that affect how one-on-one therapeutic respiratory care is reported.
This summary is intended for clinical coders, revenue cycle managers, and policy analysts seeking clarity on code purpose, service context, and where G0238 fits within outpatient respiratory care workflows.

National Reimbursement Benchmarks
Medicare's mean rate of $11.8 sits well below BUCA's average commercial mean of $17.2, indicating Medicare pays roughly $5.4 less on average for G0238 than this commercial benchmark. That gap highlights a meaningful separation between federal program levels and a subset of commercial contracts represented by BUCA.
Dispersion (P75−P25) varies across payers: Aetna's spread is $8.0, Blue Cross Blue Shield's is $6.9, Cigna's is $6.0, UnitedHealth Group's is $9.0, and BUCA's is $7.4. UnitedHealth Group exhibits the widest interquartile spread at $9.0, suggesting greater variability in mid-to-upper commercial payments, while Cigna is the tightest at $6.0, indicating more consistency around its central rates.
