Gynecology procedure
About 58353: Nonhysteroscopic thermal endometrial ablation
Reports heat-based treatment of the uterine lining without hysteroscopic guidance, typically for patients with heavy menstrual bleeding who do not desire future pregnancy.
A gynecologist uses a thermal device, often a balloon-based system, to treat the endometrial lining through the uterus without hysteroscopic guidance. The procedure is used for selected patients with heavy menstrual bleeding, commonly when future pregnancy is not desired. It is generally performed in a procedural or surgical setting rather than as an office service.
Report 58353 for nonhysteroscopic thermal treatment; use the method documented to distinguish it from cryoablation or hysteroscopic ablation. The record should identify the indication, treatment method, and procedure performed. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this uterine procedure. Medicare does not pay an assistant at surgery for this code; co-surgeons are permitted, but team surgery is not.
