CPT Code 58575 Complete Coding & Billing Guide for Laparoscopic Oncologic Hysterectomy with Omentectomy

CPT 58575 is a highly specialized procedure for treating malignancy in the gynecologic area that is performed laparoscopically. This is used by surgeons during cases where minimal access is suitable for tumour debulking and the removal of reproductive organs and omentum. Correct coding, documentation and correct use of modifiers are important to ensure proper reimbursement and audit-proof compliance, as the code is cancer-specific and contains multiple bundled elements. 

CPT Code 58575 – Description

The official definition of CPT code 58575 is:

“Laparoscopy, surgical, total hysterectomy for resection of malignancy (tumor debulking), with omentectomy including salpingo-oophorectomy, unilateral or bilateral, when performed.”

This code is for a therapeutic laparotomy with the removal of the uterus and cervix as part of the oncologic treatment. Tumor debulking, partial/ complete omentectomy, unilateral/ bilateral salpingo-oophorectomy (if clinically indicated) may also be included in the procedure. CPT 58575 is different from other laparoscopic total hysterectomy codes (58570-58573) because it is used for the diagnosis of malignancy and has oncologic components. 

The scope of CPT 58575 includes total hysterectomy, tumor debulking, omentectomy, adnexal removal if indicated, and laparoscopic closure with hemostasis.

Scenarios Where CPT Code 58575 Is Applicable

You would bill CPT code 58575 in the following situations:

Oncologic Indications:

For patients who need surgical treatment for gynecologic malignancy, including tumor debulking and removal of the omentum, with unilateral or bilateral fallopian tube and ovary removal.

Example:

A total hysterectomy with tumor debulking, partial omentectomy and bilateral salpingoophorectomy is performed on a patient with ovarian/endometrial carcinoma. The operative notes include documentation of the malignant tumor, the use of laparoscopy and any other oncologic procedures used. 

Complex Surgical Oncology Cases:

When extensive adhesions, prior surgeries, or difficult anatomy are present, documentation is important to note the factors that support procedural complexity. 

Applicable Modifiers for CPT Code 58575

When appropriate, the following modifier can be applied to code 58575: 

Modifier 22 – Increased Procedural Services

Use when surgery involves extra preparation from the complex debulking of tumor(s), adhesions, or the length of time for surgery. There needs to be documentation to support the increased service.

No other modifiers are typically necessary, except in cases where they are required by payers. 

CPT Code 58575 – Billing & Reimbursement

To ensure proper reimbursement for CPT code 58575, follow these key steps:

Justify Medical Necessity:

Record the indication for the tumor (diagnosis), its site, and indication for hysterectomy, omentectomy, and removal of any adnexa in an oncologic context. 

Use Accurate ICD-10 Codes:

Use with any malignancy diagnosis codes, such as C54.x for malignant neoplasm of the uterus, C56.x for ovarian cancer. 

Confirm Procedural Details:

The operative report should clearly document:

• Laparoscopic entry and abdominal access
• Hysterectomy in total (uterus and cervix)
• The extent of omentectomy and tumor debulking
• If either one or both fallopian tubes and ovaries have been removed.
• Operative difficulties, adhesion, or technical complexity

Detailed Documentation:

Document all oncologic procedures, any findings of a tumor and laparoscopic procedures to assist in coding, reimbursement and compliance. 

Reimbursement Considerations:

CPT 58575 reimbursement depends on documentation showing malignancy, tumor debulking, and laparoscopic oncologic procedures. Proper coding differentiates this high-complexity procedure from standard total hysterectomy codes and supports accurate payer recognition and payment.
