CPT Code 58822 Abdominal Drainage of Ovarian Abscess: Surgical Coding and Billing Guide

Managing ovarian abscesses effectively is critical to prevent complications and preserve reproductive health. Surgical intervention plays a key role when conservative management fails, especially in acute pelvic infections. Understanding procedural coding ensures accurate documentation, compliance, and reimbursement. CPT code 58822 specifically addresses the abdominal drainage approach, providing coders, clinicians, and billing specialists a clear framework for consistent reporting and clinical practice.

CPT Code 58822 – Definition

Official CPT Description:

Drainage of ovarian abscess; abdominal approach, open.

This code describes the surgical drainage of a purulent collection in the ovary via an open abdominal incision. CPT 58822 remains unchanged for 2026, per AMA, AAPC, and CMS-aligned resources. It is classified under incision procedures on the ovary in the female genital system section of CPT.

CPT 58822 is specific to the abdominal (open) approach; laparoscopic procedures for abscess drainage should be reported with the appropriate laparoscopic codes or unlisted codes when no specific code exists.

When CPT Code 58822 Is Appropriate

Report CPT 58822 when:

• An ovarian abscess requires open abdominal access for safe and effective drainage.
• The size, location, or clinical condition precludes a vaginal or percutaneous approach.
• Prior failed attempts at less invasive drainage have occurred or are contraindicated.

This code should not be reported for:

• Vaginal drainage of an abscess (use CPT 58820)

• Incidental drainage during another primary procedure without therapeutic intent
• Percutaneous drainage under radiologic guidance (report as appropriate per facility policy and payer guidelines)

CPT Code 58822 - Clinical Scenarios

Scenario 1 – Large Abdominal Ovarian Abscess

A patient presents with severe pelvic pain, fever, and imaging confirming a large right.

Ovarian abscess not accessible vaginally. The surgeon performs open abdominal drainage.

→ Report CPT 58822

Scenario 2 – Failed Less Invasive Management

A patient with a left ovarian abscess previously attempted via antibiotics and percutaneous drainage undergoes exploratory laparotomy with open drainage.

→ Report CPT 58822

Scenario 3 – Incidental Abscess Drainage During Hysterectomy

During a planned open hysterectomy, a small ovarian abscess is encountered and drained, but the primary procedure is the hysterectomy.

→ Do NOT report CPT 58822 separately; this drainage is incidental and bundled into the primary code.

CPT Code 58822 - Modifier Considerations

Appropriate modifier use depends on context:

• Modifier 50 (Bilateral Procedure): Use when both ovaries require drainage, supported by documentation.
• Modifier 22 (Increased Procedural Services): Use only if the drainage is unusually complex (e.g., extensive adhesions, distorted anatomy) with narrative justification.

Documentation must support any modifier use, especially when unbundling or clarifying procedural distinctness.

Documentation Essentials For CPT Code 58822

To support CPT 58822 and medical necessity, clinical documentation should include:

• Confirmation of the ovarian abscess and laterality
• Description of the abdominal open approach
• Indication for drainage (e.g., infection, failed noninvasive management)
• Operative findings and technique

Clear documentation helps justify the open approach and supports reimbursement review.

CPT Code 58822 - Reimbursement Considerations

Reimbursement for CPT 58822 varies by payer, place of service, and laterality. This code typically carries a standard global period, as defined by the payer. Ensure appropriate ICD‑10 diagnosis codes reflecting ovarian abscess and related clinical symptoms are reported. Preauthorization may be required depending on the payer and clinical context.
