Summary & Overview
CPT 55040: Excision of Fluid-Filled Sac of Scrotum, Unilateral
CPT code 55040 denotes the surgical removal of a fluid-filled sac from one side of the scrotum to relieve pain or discomfort. Nationally, this code captures a common minor urologic procedure used to treat symptomatic hydroceles or similar paratesticular fluid collections. It matters for payers and providers because correct coding drives appropriate reimbursement, influences site-of-service decisions, and affects quality and utilization monitoring for outpatient urologic care.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, guidance on typical service settings, and an overview of common billing modifiers and operational considerations. The publication summarizes benchmarks and policy-relevant issues such as outpatient versus inpatient site-of-service classification, documentation elements that support medical necessity, and common claims adjudication points. Data not available in the input are noted where applicable.
This summary is intended for clinicians, billing staff, and policy analysts seeking a clear national-level briefing on CPT code 55040, its clinical use, and the payer coverage landscape.

Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the urology clinic with an enlarging, painless left scrotal swelling present for several months and intermittent discomfort with activity. On physical exam the swelling is transilluminant and consistent with a hydrocele. Ultrasound confirms a simple unilocular fluid collection surrounding the left testicle without evidence of varicocele or testicular mass. The patient elects for surgical repair. In the operating room under regional or general anesthesia, the surgeon makes a small scrotal incision, evacuates the serous fluid, excises the hydrocele sac (sac excision), and achieves hemostasis. Recovery includes short post-anesthesia monitoring and routine wound care instructions. Typical preoperative workflow includes history and physical, informed consent, scrotal ultrasound, anesthesia evaluation, and scheduling of the ambulatory surgical case. Postoperative workflow includes discharge instructions, pain control, activity restrictions, and a follow-up visit to assess wound healing and resolution of the hydrocele.
