CPT 58920: Ovarian Wedge Resection/Partial Oophorectomy

Headline: CPT code 58920: Open ovarian wedge resection/partial oophorectomy for ovarian cysts

Lead: CPT code 58920 denotes an abdominal surgical procedure to remove a wedge-shaped portion or half of one or both ovaries to treat ovarian cysts. The code captures conservative ovarian-sparing resections performed via an open abdominal approach and is relevant to gynecologic surgeons, hospital billing teams, and payers evaluating procedural utilization and payment for cyst-related ovarian surgery.

CPT code 58920 represents a targeted ovarian surgical intervention intended to excise cystic tissue while preserving ovarian function when possible. Nationally, the procedure matters for clinical management of benign ovarian cysts, surgical resource planning, and coverage determinations. Key payers commonly involved in coverage and payment for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will learn the clinical context of the code, typical sites of service, and which payers are relevant to comparative coverage discussions. The publication summarizes coding intent and clinical application, outlines typical service settings, and indicates where input data were not provided. Data not available in the input are noted explicitly where applicable.

Billing Code Overview

CPT code 58920 describes an open surgical ovarian procedure in which the provider removes a wedge-shaped (pie-shaped) portion or bisects (removes half of) one or both ovaries via an abdominal incision. The procedure is performed to treat ovarian cysts by excising the cyst-bearing portion of the ovary while preserving remaining ovarian tissue.

Service type: Surgical procedure — ovarian wedge resection or partial oophorectomy
Typical site of service: Hospital operating room or ambulatory surgical center via an abdominal incision

Clinical & Coding Specifications

Clinical Context

A 32-year-old woman presents with persistent unilateral pelvic pain and a transvaginal ultrasound demonstrating a complex ovarian cyst measuring 6 cm with suspected hemorrhagic components. Conservative management with analgesics and follow-up imaging over 6–8 weeks failed to resolve the cyst and symptoms. The gynecologic surgeon schedules an operative ovarian wedge resection via an abdominal approach (laparotomy or mini-laparotomy) to remove the cyst and preserve ovarian tissue. Preoperative workflow includes informed consent, anesthesia evaluation, pregnancy test, coagulation assessment, and prophylactic antibiotics. Intraoperatively, the surgeon performs a pie-shaped wedge resection or partial oophorectomy of one ovary, controls hemostasis, and sends cyst tissue for pathology. Postoperative care includes monitoring in recovery, pain control, discharge instructions with activity restrictions, and pathology follow-up to guide any further management.

Modifier	Description	When to Use
`00`	No modifier — default	Use when no other modifier applies and service is billed as usual.
`22`	Increased procedural services	Use when work required is substantially greater than typical for `58920` (document justification).
`52`	Reduced services	Use when the procedure is partially performed or abbreviated.
`53`	Discontinued procedure	Use when the procedure is started but halted for patient-related or surgical reasons.
`62`	Two surgeons	Use when two surgeons with distinct roles perform portions of the procedure.
`63`	Procedure performed on infants less than 4 kg	Rare; use if procedure performed on neonate meeting the weight criterion.

`80`	Assistant surgeon	Use when an assistant surgeon participates and billing requires reporting of assistant services.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist service	Use when an advanced practice clinician provides a portion of the service as authorized by payer policy.
