Summary & Overview
CPT 59121: Tubal or Ovarian Incision to Remove Small Ectopic Pregnancy
CPT code 59121 denotes a conservative surgical procedure to remove a small ectopic pregnancy by making an incision into the fallopian tube or ovary. This code is nationally relevant because ectopic pregnancy management affects maternal morbidity, surgical resource utilization, and payer coverage decisions for urgent gynecologic care. The code applies to minimally invasive abdominal procedures performed in ambulatory surgical centers or hospital operating rooms.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for 59121, how the procedure is typically performed, and the typical sites of service. The analysis summarizes common billing considerations and expected service lines, and highlights benchmarks and policy updates where available. Data not available in the input is noted explicitly when relevant.
This summary is intended to orient clinicians, coding professionals, and policy analysts to the purpose and clinical setting of CPT code 59121, and to identify where further payer-specific reimbursement and authorization details would be required for implementation and claims submission.
Billing Code Overview
CPT code 59121 describes a surgical procedure in which the provider makes a hole or incision into the fallopian tube or ovary to remove a small ectopic pregnancy from that location. The procedure is typically performed through a small abdominal incision and involves direct access to the adnexal structures to excise the ectopic gestation while preserving surrounding tissue when possible.
-
Service type: Surgical removal of ectopic pregnancy via tubal or ovarian incision (conservative adnexal surgery)
-
Typical site of service: Ambulatory surgical center or hospital operating room for a minimally invasive abdominal procedure
Clinical & Coding Specifications
Clinical Context
A 29-year-old patient presents to the emergency department with acute lower abdominal pain and light vaginal bleeding at 7 weeks' gestation. Transvaginal ultrasound demonstrates an adnexal mass with absence of an intrauterine pregnancy and a small amount of free pelvic fluid, consistent with a suspected tubal ectopic pregnancy. After stabilization and counseling, the gynecologic surgeon schedules an operative procedure to remove the ectopic pregnancy while preserving the fallopian tube. The typical workflow includes preoperative evaluation (history, labs including type and screen, quantitative hCG), informed consent, general anesthesia, and a small abdominal incision for laparoscopic access. The surgeon identifies the ectopic focus on the fallopian tube or ovary, makes a small incision or salpingostomy/ovarian incision, removes the ectopic tissue, achieves hemostasis, irrigates the pelvis, and closes port sites. Postoperative recovery includes monitoring for bleeding and infection, analgesia, Rh immunoglobulin if indicated, and follow-up hCG levels until negative. Typical site of service is an ambulatory surgical center or hospital operating room. Service type is a minor gynecologic operative procedure for ectopic pregnancy removal via salpingostomy or ovarian incision.
