CPT code 55100 covers incision and drainage of a scrotal abscess, a focused surgical procedure to evacuate pus from the scrotum to treat an acute infection. This code is clinically important because timely drainage is the primary treatment for scrotal abscesses, influences site-of-care decisions (ambulatory surgical center, hospital outpatient, or emergency department), and has implications for coding, billing, and quality measurement across national payers. Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

The publication summarizes national benchmarks where available, highlights billing nuances and common modifiers in use, and outlines policy considerations that affect coverage and reimbursement for acute surgical procedures. It also provides operational considerations for claims processing and typical documentation elements that support medical necessity.
