Summary & Overview
CPT 58559: Hysteroscopic Lysis of Intrauterine Adhesions
CPT code 58559 represents hysteroscopic lysis of intrauterine adhesions — a minimally invasive gynecologic procedure to break down scar tissue within the uterine cavity. This code captures a targeted operative intervention that can impact fertility, menstrual function, and uterine anatomy, making it clinically significant across obstetrics and gynecology care pathways. Nationally, accurate coding affects quality measurement, care coordination, and payment for operative hysteroscopy services.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the procedural nature of the service. The publication summarizes common billing considerations, relevant modifiers when reporting operative hysteroscopy, and where to find guidance on coding and documentation.
The analysis provides operational benchmarks and coding guidance to inform hospital, ambulatory surgical center, and physician practice workflows. Clinical readers will gain clarity on when 58559 is used in the care pathway for intrauterine adhesions; administrative readers will see common reporting contexts and payer coverage considerations. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 58559 describes the surgical lysis of intrauterine adhesions (scar tissue) performed through a hysteroscope. The procedure involves breaking down or separating scar tissue that has formed inside the uterine cavity to restore normal uterine anatomy.
-
Service type: Hysteroscopic operative procedure
-
Typical site of service: Ambulatory surgical center or hospital operating room, performed by a gynecologic surgeon using hysteroscopic instrumentation
Clinical & Coding Specifications
Clinical Context
A typical patient is a reproductive-age woman presenting with infertility, recurrent pregnancy loss, abnormal uterine bleeding, or cyclical pelvic pain after prior uterine instrumentation (e.g., dilation and curettage), cesarean delivery, or infection. The gynecologist evaluates with history, pelvic exam, transvaginal ultrasound, and saline-infusion sonohysterography or hysterosalpingography demonstrating intrauterine adhesions (Asherman syndrome) or synechiae. After counseling, the patient is scheduled for operative hysteroscopy with lysis of intrauterine adhesions (58559).
The clinical workflow: preoperative evaluation includes informed consent, review of imaging, and optimization of comorbidities. In the operating room or ambulatory surgery center (typical site of service), under monitored anesthesia care or general anesthesia, a hysteroscope is introduced transcervically. Adhesions are lysed using scissors, electrosurgical instruments, or a resectoscope as needed. Distention media is used for visualization. The surgeon documents indications, operative findings (location and extent of adhesions), lysis technique, estimated blood loss, any concomitant procedures, and postoperative plan (e.g., intrauterine balloon or estrogen therapy to prevent reformation). Typical recovery is same-day discharge with activity restrictions and follow-up imaging or hysteroscopic re-evaluation as indicated.
