CPT code 27301 covers incision and drainage of deep abscesses, bursae, or hematomas in the thigh or knee region — a targeted surgical intervention to manage deep soft-tissue infection and relieve pain. This procedure is clinically important because timely source control can reduce morbidity, prevent systemic spread of infection, and often determines the need for inpatient care versus outpatient management. Nationally, consistent coding of procedures like 27301 affects surgical quality measurement, resource utilization, and payment across acute and ambulatory settings.

Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of clinical context and typical settings for the service, benchmark considerations for utilization and site-of-service selection, common billing and documentation themes that influence payment, and relevant modifiers and billing complexities summarized for operational use. The content outlines where 27301 is typically performed (emergency departments, hospitals, and ambulatory surgical centers) and highlights policy and billing areas that tend to drive variability, such as anesthesia requirements, extent of debridement, and concurrent procedures.

Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes is noted where applicable. This summary is intended for billing, clinical operations, and policy audiences seeking a national overview of CPT code 27301 and its role in managing deep thigh or knee infections.
