Varicocele: Selected Treatments — CPB 0413 | AETNA Coverage Update

Aetna modified CPB 0413 for varicocele treatments, effective September 26, 2025. Here's what billing teams need to know before claims go out the door.

Aetna, a CVS Health company, updated its varicocele coverage policy under CPB 0413 to define exactly when percutaneous embolization, ligation, and microsurgical varicocelectomy meet medical necessity. The policy covers CPT 37241 for vascular embolization and a full range of excision and ligation codes (55530–55550) when specific clinical criteria are met. If your practice bills varicocele procedures for Aetna members, the criteria in this update determine whether you get paid or get denied.

Aetna Varicocele Coverage Criteria and Medical Necessity Requirements 2025

The Aetna varicocele coverage policy under CPB 0413 is built around four specific indications. Meet one of them, and percutaneous embolization or ligation is medically necessary. Miss all four, and Aetna treats the procedure as experimental.

Here are the four covered indications, exactly as the policy defines them:

This is a tight list. Aetna is not covering varicocele treatment broadly — they're covering it when there's a documented functional problem: testicular size loss, proven sperm parameter deficits, a recurrence after surgery, or pain. A clinical finding of varicocele alone doesn't get you there.

For CPT 37241 (vascular embolization or occlusion, including all radiological supervision and interpretation), medical necessity hinges on one of those four criteria being documented in the patient record before the procedure. No documentation, no reimbursement. Your clinical team needs to know this before they write the op note.

Microsurgical varicocelectomy is also covered — Aetna calls it "an acceptable alternative method" — when the same criteria are met. So CPT codes 55530 through 55550 carry the same coverage logic. The approach changes; the criteria don't.

Prior authorization requirements aren't explicitly called out in CPB 0413's criteria section, but for any procedure in this category, check Aetna's plan-level prior auth requirements before scheduling. Varicocele embolization under CPT 37241 frequently requires prior auth at the plan level even when the coverage policy criteria are met. Confirm this with the specific member's plan before the procedure date.

The ICD-10-CM codes that map to covered indications include I86.1 (scrotal varices), E29.1 (testicular hypofunction), and the N46 family — which covers azoospermia (N46.1 through N46.9) and oligospermia (N46.11–N46.129). These are your supporting diagnosis codes for the infertility and testicular growth retardation indications. Pair them correctly with your procedure code or expect a claim denial on the front end.

Aetna Varicocele Exclusions and Non-Covered Indications

Aetna is direct here: percutaneous embolization or ligation for patients who don't meet the four criteria above is experimental and investigational. There's no gray zone in the policy language.

Subclinical varicoceles are explicitly excluded from coverage across every ligation code — CPT 55530 through 55550. The code descriptions in this policy all carry the notation "not covered for subclinical varicoceles." This is the most common denial trigger in this code family. If your documentation doesn't establish a clinical grade 2 or 3 varicocele — or doesn't tie the varicocele to one of the four covered indications — you're billing into a denial.

The HCPCS code J1430 (injection, ethanolamine oleate, 100 mg) maps to sclerosant-based occlusion techniques. The policy groups this with experimental approaches unless the procedure meets the standard criteria. If your interventional radiology team is using ethanolamine oleate or sodium tetradecyl sulfate as part of an embolization, confirm the full procedural context meets CPB 0413 criteria or don't bill it to Aetna expecting payment.

CPT, HCPCS, and ICD-10 Codes for Varicocele Treatment Under CPB 0413

Covered CPT Codes (When Selection Criteria Are Met)

Code	Type	Description Copy
37241	CPT	Vascular embolization or occlusion, inclusive of all radiological supervision and interpretation

Other CPT Codes Related to CPB 0413

These codes are covered when the four medical necessity criteria are met but are explicitly not covered for subclinical varicoceles.

Covered HCPCS Codes

Code	Type	Description Copy
J1430	HCPCS	Injection, ethanolamine oleate, 100 mg

Key ICD-10-CM Diagnosis Codes

The N46 code family is the largest code block in this policy. Use the most specific code available. N46.11–N46.129 covers oligospermia for infertility cases. N46.1 through N46.9 covers azoospermia variants. Unspecified codes at the end of that range will draw scrutiny — code to the highest level of specificity your documentation supports.
