Summary & Overview
HCPCS Level II S4028: Microsurgical Epididymal Sperm Aspiration (MESA)
HCPCS Level II code S4028 represents microsurgical epididymal sperm aspiration (MESA), a targeted sperm retrieval procedure used in assisted reproduction when ejaculation cannot provide viable sperm. This code identifies a specialized surgical service with implications for access to fertility care and coverage determinations nationally. Payers commonly involved in coverage decisions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise briefing on clinical context and why MESA matters for fertility treatment planning, followed by coverage and billing considerations across major payers. The publication summarizes benchmarks and common payer policies where available, highlights coding and site-of-service implications for outpatient surgical centers and operating rooms, and outlines areas where policy updates or payer variability commonly affect claim adjudication. Data not available in the input is noted where relevant. The piece aims to inform providers, billing professionals, and policy analysts about the clinical purpose of S4028, typical settings, and the scope of payer involvement in reimbursement and authorization processes.
Billing Code Overview
HCPCS Level II code S4028 describes microsurgical epididymal sperm aspiration (MESA). This is a procedural service performed to retrieve sperm directly from the epididymis using microsurgical techniques for use in assisted reproductive procedures.
Service type: Microsurgical sperm retrieval procedure
Typical site of service: Operating room or outpatient surgical center, often performed by urology or reproductive surgery specialists
Clinical & Coding Specifications
Clinical Context
A 36-year-old male with a history of obstructive azoospermia presents to a reproductive urology clinic for evaluation after 18 months of infertility with a fertile female partner. Prior history includes right-sided vasectomy and a prior episode of epididymitis. Semen analysis demonstrates azoospermia with normal semen volume and normal hormone panel. Scrotal ultrasound shows dilated epididymal tubules consistent with obstructive etiology. The patient elects microsurgical epididymal sperm aspiration (S4028, MESA) for retrieval of motile sperm for use in in vitro fertilization with intracytoplasmic sperm injection.
The clinical workflow: the patient completes preoperative counseling, infectious disease screening, and consent. On the day of service the procedure is performed in an ambulatory surgery center or hospital outpatient setting under general or regional anesthesia. Under operative microscopy, the urologist exposes the epididymis, makes a small incision in an epididymal tubule, and aspirates fluid to obtain sperm. Specimens are immediately evaluated by andrologists/embryologists in the adjacent laboratory; motile sperm are processed and either cryopreserved or handed off for IVF/ICSI on the same day. Postoperative recovery includes short observation and discharge with wound care and activity restrictions.
