CPT Code 58770 Salpingo-Oophorectomy (Open Surgical Removal/Repair of Tubes and Ovaries)

OBGYN medical billing for complex surgical procedures like CPT Code 58770 requires precise coding and documentation to ensure accurate reimbursement. 

This code is applied in open surgical scenarios involving the removal or repair of one or both fallopian tubes and ovaries, often related to fertility restoration, ovarian pathology, or other gynecologic indications. 

Proper documentation and clear differentiation from laparoscopic or minimally invasive procedures are essential to reduce denials and support compliant billing.

CPT Code 58770 – Definition

Official CPT Description:

Salpingostomy (salpingoneostomy).

This code describes an open (non-laparoscopic) abdominal procedure performed to restore tubal patency, allowing the passage of ova from the ovary into the uterus. CPT 58770 remains unchanged for 2026 according to AMA, AAPC, and CMS-aligned updates.

When CPT Code 58770 Is Appropriate

CPT 58770 is reported for non-obstetrical conditions, including:

• Distal tubal occlusion or blockage
• Hydrosalpinx
• Tubal scarring due to pelvic inflammatory disease
• Infertility requiring surgical tubal repair

This code applies only to an open surgical approach. Laparoscopic salpingostomy procedures must be reported using the appropriate laparoscopic CPT codes.

CPT Code 58770 - Clinical Scenarios

Scenario 1 – Infertility Due to Tubal Occlusion

A 32-year-old patient with secondary infertility is found to have distal tubal blockage. An open abdominal salpingostomy is performed to restore tubal patency.

→ Report CPT 58770

Scenario 2 – Hydrosalpinx Repair

A patient presents with chronic pelvic pain and a hydrosalpinx affecting the right fallopian tube. Open surgical salpingostomy is performed to remove the obstruction.

→ Report CPT 58770

Scenario 3 – Incidental Lysis During Another Procedure

During an open abdominal procedure for ovarian cyst removal, minor adhesions on the fallopian tube are released incidentally.

→ Do NOT report CPT 58770 separately; this is incidental and bundled into the primary procedure.

CPT Code 58770 Modifier Considerations

• Modifier 50 (Bilateral Procedure):
  Used when salpingostomy is performed on both fallopian tubes during the same operative session, subject to payer guidelines.
• Modifier 22 (Increased Procedural Services):
  May be reported when extensive scarring or abnormal anatomy significantly increases procedural complexity. Supporting documentation is required.

Billing and Documentation Guidelines For CPT Code 58770

To support CPT 58770, documentation should clearly include:

• Confirmation of an open abdominal approach
• Laterality (right, left, or bilateral)
• Description of tubal pathology
• Medical necessity for salpingostomy

Diagnosis codes must support tubal disease or infertility and should not reference pregnancy or obstetrical conditions.

Reimbursement Considerations CPT Code 58770

Reimbursement varies based on payer infertility coverage policies, place of service, and laterality. Although CPT 58770 has no descriptor changes for 2026, payment rates may change annually under CMS fee schedule updates. Preauthorization is recommended for infertility-related cases.
