CPT® Code 59121

The CPT® Code 59121 refers to the surgical treatment of an ectopic pregnancy, specifically when the procedure is performed without the removal of the fallopian tube (salpingectomy) or the ovary (oophorectomy). An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, commonly in the fallopian tube or, less frequently, in the ovary. This condition can pose significant health risks, including internal bleeding, and requires prompt surgical intervention. The procedure involves making an incision either in the abdomen or through the vagina to access the affected fallopian tube or ovary. Unlike the related procedure described by CPT® Code 59120, which involves the excision of the tube or ovary, the approach for CPT® Code 59121 focuses on preserving these structures while effectively removing the ectopic tissue. The surgical techniques employed may include blunt and sharp dissection, the use of electrocautery for bleeding control, and irrigation methods to ensure the complete removal of the ectopic pregnancy while minimizing damage to surrounding tissues. This preservation-focused approach is critical for maintaining reproductive potential in patients experiencing ectopic pregnancies.
