Is benefit coverage approved for ovarian cyst removal/biopsy with bilateral salpingo-oophorectomy for a patient with a complex ovarian cyst and history of lower left quadrant (LLQ) pain?

Benefit Coverage Decision for Ovarian Cyst Removal/Biopsy with Bilateral Salpingo-Oophorectomy

Benefit coverage should be approved for both CPT 58661 (laparoscopic bilateral salpingo-oophorectomy) and CPT 58100 (biopsy) based on the documented complex ovarian cyst with progressive size increase from 57x40x54 mm to 57x40x74 mm over 3-4 months in a postmenopausal patient.

Clinical Justification for Approval

Indication for Surgical Intervention

The documented progression of the complex ovarian cyst meets established criteria for surgical removal. 1

• The cyst has demonstrated interval growth over 3-4 months (from 54 mm to 74 mm in maximum dimension), which is a concerning feature requiring surgical evaluation 2
• Complex ovarian cysts in postmenopausal women warrant surgical intervention because functional cysts should not occur after menopause 2
• The patient's postmenopausal status combined with a persistent, enlarging complex cyst creates appropriate indication for bilateral salpingo-oophorectomy 1

Standard Surgical Approach for This Clinical Scenario

Bilateral salpingo-oophorectomy is the standard surgical procedure for postmenopausal women with ovarian masses requiring removal. 1

• ESMO guidelines specify that in postmenopausal women with ovarian involvement, total abdominal hysterectomy and bilateral salpingo-oophorectomy should be carried out with careful surgical staging 1
• The 2024 ESGO-ESMO-ESP consensus recommends complete surgical resection including bilateral salpingo-oophorectomy for stage I-II ovarian pathology in postmenopausal patients 1
• Standard surgery for postmenopausal women eliminates the need for ongoing gynecologic surveillance and provides definitive cancer prevention 3

Biopsy Component (CPT 58100)

Intraoperative biopsy and pathological evaluation are essential components of surgical management for complex ovarian masses. 1

• Surgical staging includes peritoneal biopsies and cytological analysis to differentiate between benign, borderline, or malignant disease 1
• Histological examination is required to determine whether the lesion is a benign cyst, borderline tumor, or invasive carcinoma, which directly impacts subsequent management 1, 4
• The biopsy procedure allows for proper staging and guides decisions about adjuvant therapy if malignancy is discovered 1

MCG Criteria Alignment

CPT 58661 Coverage Under MCG S-775

The case clearly meets MCG criteria for laparoscopic oophorectomy or excision of adnexal mass. 2

• MCG S-775 specifically indicates coverage for "adnexal mass or ovarian disease (e.g., cyst) requiring removal"
• The documented complex ovarian cyst with progressive enlargement constitutes an adnexal mass requiring removal
• The patient's symptoms (rare RLQ pain) combined with imaging findings support the medical necessity

CPT 58100 Coverage Considerations

While CPT 58100 falls under a GRG that UC cannot directly authorize, the clinical scenario supports coverage through the broader surgical authorization. 1

• The GRG includes "pelvic malignancy or mass requiring intervention, including biopsy procedure"
• Biopsy is an integral component of the surgical staging procedure for ovarian masses 1
• The biopsy cannot be separated from the primary surgical procedure as it is necessary for definitive diagnosis and staging 1, 4

Risk Assessment Supporting Surgical Intervention

Features Requiring Surgical Evaluation

The combination of postmenopausal status, complex cyst characteristics, and documented growth creates appropriate indication for surgery despite some reassuring features. 2

• While the cyst lacks solid components or papillary projections on imaging, the progressive size increase over 3-4 months is concerning 2
• Postmenopausal women should not develop functional cysts, making any persistent ovarian mass suspicious 2
• Even with normal CA125 levels (if obtained), continued surveillance alone is insufficient for enlarging complex cysts in postmenopausal women 2

Cancer Prevention Benefit

Bilateral salpingo-oophorectomy provides definitive cancer prevention that cannot be achieved through surveillance alone. 3, 5, 6

• The procedure eliminates the risk of ovarian cancer entirely, which is particularly important in postmenopausal women 3
• Opportunistic salpingectomy reduces the risk of high-grade serous ovarian cancer, which often originates in the fallopian tubes 7, 5, 6
• The surgery eliminates the need for ongoing gynecologic surveillance including repeated imaging and potential future interventions 3

Important Clinical Caveats

Surgical Staging Requirements

If malignancy or borderline pathology is discovered intraoperatively, comprehensive staging must be performed. 1, 4

• Staging should include peritoneal washings, infracolic omentectomy, and multiple peritoneal biopsies 1, 4
• Careful inspection of the abdominal cavity including liver, diaphragm, omentum, and peritoneal surfaces is required 1, 3
• Lymphadenectomy should only be performed if lymph nodes appear suspicious or enlarged 4

Pathology Review

All specimens should undergo thorough histological examination by an experienced pathologist. 1, 4

• Borderline tumors require expert pathology review as they have distinct management implications 4
• If borderline or malignant pathology is identified, the case should be reviewed by a gynecologic oncologist 4
• Long-term surveillance is required if borderline pathology is diagnosed, as 70% of recurrences occur after 5 years 4
