Obstetrics and Gynecology CPT Codes in the ASC Setting
Gynecologic surgery has moved steadily into the outpatient setting, and many procedures once requiring a hospital stay are now done in ambulatory surgery centers. OB/GYN surgeons in an ASC network handle a broad mix of diagnostic and therapeutic work on the female genital tract, billed largely from CPT 56405 through 58999. Whether a given code can be billed in an ASC depends on its CMS Addendum status: codes on Addendum AA sit on the ASC Covered Procedures List, meaning Medicare pays them in an ASC, while Addendum EE codes are excluded.
This hub maps 219 ASC-relevant OB/GYN CPT codes, with a reference page for each, including 58558 (hysteroscopy with biopsy) and 58571 (total laparoscopic hysterectomy with removal of tube(s) and/or ovary(s), uterus 250 g or less). Use the linked pages to confirm coverage framing and the documentation that supports each claim.

Are OB/GYN procedures performed in an ambulatory surgery center?
Yes. Many gynecologic surgeries are routinely done in ASCs, including hysteroscopic biopsy, endometrial ablation, pelvic and bladder repair, and minimally invasive hysterectomy such as 58571. Whether Medicare pays a specific code in an ASC depends on its CMS Addendum status, with Addendum AA codes sitting on the ASC Covered Procedures List.
What CPT codes does OB/GYN use for ASC surgery?
Outpatient gynecologic surgery is billed largely from the female genital CPT range 56405 through 58999. This includes hysteroscopy codes like 58558, pelvic and bladder repair such as 57288, ablation procedures like 58353, and laparoscopic hysterectomy like 58571. Our dataset maps 219 ASC-relevant OB/GYN codes, each with its own reference page.
What is the difference between place of service 24 and 11 for gynecologic procedures?
Place of service 24 indicates the procedure was performed in an ambulatory surgery center, while place of service 11 indicates an office setting. The same procedure can be reported in either location, but the place of service affects how the claim is priced and which facility payment, if any, applies.
