CPT Code 59120 Excision Procedures for Maternity Care and Delivery

Official CPT® Description (AAPC/AMA): “Surgical treatment of ectopic pregnancy; with salpingectomy and/or oophorectomy, abdominal or vaginal approach.”

CPT code 59120 is reported when the physician surgically treats an ectopic pregnancy, specifically a tubal or ovarian ectopic, by removing the fallopian tube (salpingectomy) and/or ovary (oophorectomy) using either an abdominal or vaginal surgical approach. This is a major, life-saving operation performed when a fertilized egg implants outside the uterus and threatens the patient’s health.

Description of the Procedure Of CPT Code 59120

During this procedure, the surgeon accesses the pelvic cavity through an abdominal or vaginal incision to remove the affected fallopian tube and/or ovary that contains the ectopic pregnancy.

The main goals are to stop internal bleeding, remove the abnormal pregnancy, and preserve reproductive and overall health where possible.

This procedure is most often performed in emergency settings due to ruptured or bleeding ectopic pregnancies, but it can also be done electively when imaging confirms a nonviable ectopic gestation.

Key Surgical Steps May Include:

• Making an abdominal (laparotomy) or vaginal incision.
• Identifying the location of the ectopic gestation.
• Removing the affected tube and/or ovary.
• Controlling bleeding and repairing any surrounding structures is necessary.
• Inspecting the contralateral adnexa and uterus for further abnormalities.

This code applies only when organ removal (salpingectomy and/or oophorectomy) is performed. If a conservative treatment like salpingostomy is done, report CPT 59121 instead.

When to Use CPT 59120

Use CPT 59120 when:

• The patient has a confirmed ectopic pregnancy located in the fallopian tube or ovary.
• Surgical removal of the affected organ(s) is necessary to stop bleeding or prevent rupture.
• The approach is abdominal or vaginal, not laparoscopic.
• The procedure involves the removal of tissue (not drainage or simple incision).

For laparoscopic treatment, use CPT 59151 or other applicable laparoscopic ectopic codes.

Modifiers For CPT Code 59120

Use modifiers to clarify provider roles or surgical details:

• Modifier 50 – Bilateral procedure (if both adnexa removed).
• Modifier 51 – Multiple procedures in the same session.
• Modifier 54/55 – For split surgical and postoperative care.
• Modifier 59 – Distinct procedural service, when appropriate.
• Modifier RT/LT – To specify laterality for payer clarity.

Documentation Requirements For Using CPT Code 59120

Accurate documentation helps with compliance and reimbursement.

• Diagnosis and location of the ectopic pregnancy. 
• Operative approach (abdominal or vaginal).
• Organs removed (tube, ovary, or both).
• Estimated blood loss and intraoperative findings.
• Justification for surgery (e.g., rupture, hemorrhage risk).
• Postoperative care plan and follow-up instructions.

Reimbursement and Billing Insights for CPT Code 59120

The reimbursement for 59120 will depend on the particulars of the payer contract, geographic location, place of service, procedural complexity, and emergency situations.

Key billing factors to take into account are:

• Report CPT 59120 only for open or vaginal surgical treatment of an ectopic pregnancy requiring salpingectomy and/or oophorectomy.
• Do not report separate salpingectomy or oophorectomy codes for tissue removal included in CPT 59120.
• Apply appropriate modifiers when additional procedures are performed or when increased procedural complexity is documented.
• Review National Correct Coding Initiative (NCCI) edits before billing with other gynecologic procedures.
• Ensure documentation clearly supports the medical necessity of emergency surgical intervention.

CPT 59120 generally carries a 90-day global surgical period, during which routine postoperative care related to the procedure is included in the global payment.

Common Coding Challenges For CPT Code 59120

Documentation needed to support the coding of ectopic pregnancy surgeries like CPT 59120 may be complicated due to the clinical urgency of the situation. There are some issues with reporting and code selection that can be avoided and lead to many denials or delays. The most common problems and solutions are listed below: 

Incomplete Description of Surgical Approach

When it is not described in the operative note, coders may have trouble when the surgery was performed. Always verify if it was performed via abdominal approach or vaginal approach as this will directly impact the correct cpt code (and the classification for the payer). 

Unclear Organ Involvement

This code is only used if the fallopian tube and/or ovary has been removed. Note: The coding for “ectopic pregnancy treated surgically” is not specific to the organ and coders may assign the wrong CPT (e.g., 59121). Instruct providers to be explicit in documenting if a salpingectomy or an oophorectomy or both have been performed. 

Mixing Conservative and Definitive Procedures

Partial removal or conservative procedures may be offered by some providers to maintain fertility. Coders can misinterpret where documentation is not clear if it is a complete removal or incision and evacuation. The operative summary should accurately outline the tissue that was removed. 

Emergency Setting Documentation Gaps

In the case of emergency where operative notes may be written down later or may be incomplete. Claims may be denied if missing information includes estimated blood loss, the status of the rupture, or hemodynamic instability. Always ensure an addendum or brief summary is added postoperatively to strengthen the claim. 

Bundled or Overlapping Services

Certain procedures such as wound closure or irrigation may be over-reported by coders because they are part of the global package. Postoperative care and services are included in the 90-day global period for CPT 59120 and should not be coded separately. 

Insufficient Medical Necessity Support

While this is a common emergent procedure, it is possible that payers will still expect a clear clinical justification in elective/prior scheduled cases. Diagnosis, imaging, and rationale for surgery versus medical management for ectopic pregnancy. 

Example Clinical Scenarios

Scenario 1 – Tubal Rupture:

A patient comes into ER with very high abdo pain and bleeding. On physical examination, the tubal ectopic pregnancy is found. The surgeon will do an abdominal salpingectomy to remove the affected tube. → Report 59120. 

Scenario 2 – Ovarian Ectopic Pregnancy:

During exploratory laparotomy, a nonviable ovarian ectopic pregnancy is found. The surgeon removes the ovary and controls bleeding. → Report 59120.

Scenario 3 – Combined Ectopic Surgery:

A patient with an ectopic pregnancy and extensive adhesions undergoes salpingectomy and partial oophorectomy. → Report 59120, with clear documentation of findings and structures removed.
