CPT Code 58925 Ovarian Cystectomy: Accurate Coding and OBGYN Medical Billing Guide

Ovarian cysts can cause pain, hormonal imbalance, or fertility concerns, making precise surgical removal essential. Accurate coding and detailed documentation are critical for proper OBGYN medical billing and maximizing reimbursement. Capturing surgical approach, laterality, cyst characteristics, and preservation of ovarian tissue ensures claims reflect the full complexity of the procedure. This guideline provides best practices for coding, reporting, and documentation for CPT 58925 ovarian cystectomy procedures.

Definition and Scope For CPT Code 58925

CPT 58925, as defined by the American Medical Association (AMA) and referenced on AAPC’s Codify platform (unchanged through 2025/2026 updates), is:

Ovarian cystectomy, unilateral or bilateral.

This code describes an open surgical procedure (via laparotomy or minilaparotomy) in which one or more ovarian cysts are carefully excised while preserving the remaining ovarian tissue. The procedure is performed for symptomatic benign cysts, endometriomas, or other non-malignant cystic lesions to relieve pain, prevent torsion or rupture, or maintain fertility and hormonal function. The ovarian defect is repaired to ensure hemostasis and tissue integrity.

Scenarios for CPT 58925

These real-world examples illustrate when CPT 58925 is appropriately reported, helping coders and practices ensure accurate OBGYN medical billing and proper reimbursement.

Unilateral Ovarian Cystectomy for Symptomatic Cyst
A patient has a large, painful ovarian cyst unresponsive to conservative treatment. The surgeon excises the cyst via open abdominal incision, preserving ovarian tissue. CPT 58925 is reported.

Bilateral Cystectomy for Recurrent Lesions
Both ovaries contain recurrent benign cysts. Each cyst is excised, and remaining ovarian tissue is preserved. Laterality and approach are documented, supporting CPT 58925.

Excision of Endometrioma Affecting Fertility
A patient with an endometrioma impacting fertility undergoes open cystectomy to remove the lesion while maintaining ovarian function. CPT 58925 is appropriate.

Cystectomy During a Hysterectomy (Distinct Procedure)
A cystectomy is performed alongside a hysterectomy, documented as separate and distinct, justifying reporting CPT 58925 with the appropriate modifier (-59/-XU).

Complex Ovarian Cyst in Adhesed Ovary
Extensive adhesions make cyst excision more challenging. Documentation supports increased complexity, potentially warranting modifier -22 with CPT 58925.

Modifiers for CPT 58925

Appropriate modifier use depends on clinical context:

• Modifier 59 (Distinct Procedural Service): When laparoscopic oophorectomy is performed as a separate procedure during the same session with clear clinical indication.
   
• Modifier 22 (Increased Procedural Services): When operative complexity significantly exceeds typical expectations (e.g., extensive adhesions), supported by operative documentation.
   

Modifiers must be supported by appropriate clinical and operative notes.

Documentation Requirements for CPT 58925

Supporting documentation should include:

• Indication for laparoscopic oophorectomy (e.g., cyst, torsion)
   
• Laterality (right or left)
   
• Description of laparoscopic approach and findings
   
• Distinction from other concurrent procedures
   

Clear documentation improves claim acceptance and reduces denials.

Reimbursement for CPT 58925

• Reimbursement for CPT 58925 varies by payer, place of service, and laterality. Ensure that appropriate ICD‑10 diagnosis codes reflecting ovarian pathology accompany the procedure. Preauthorization may be required in some clinical settings, particularly for benign conditions.
