Scrotal Ultrasound - (0548) — MM 0548 | CIGNA Coverage Update

Cigna modified MM 0548 (scrotal ultrasound coverage policy) on September 26, 2025. Billing teams that bill CPT 76870 for Cigna members need to confirm their ICD-10 pairings match the updated medical necessity criteria before claims go out the door.

Cigna Healthcare updated Coverage Policy MM 0548, which governs scrotal ultrasound billed under CPT 76870. The policy now maps coverage to a specific list of 110+ ICD-10-CM diagnosis codes spanning testicular torsion, epididymitis, hydrocele, male infertility, scrotal malignancy, and undescended testes. If your diagnosis code isn't on that list, expect a claim denial. Urology, radiology, and primary care practices billing scrotal ultrasound to Cigna should audit their charge capture and superbill templates against this updated code set before the September 26, 2025 effective date.

Cigna Scrotal Ultrasound Coverage Criteria and Medical Necessity Requirements 2025

The Cigna scrotal ultrasound coverage policy under MM 0548 covers CPT 76870 (Ultrasound, scrotum and contents) when medical necessity criteria are met. Coverage ties directly to an approved ICD-10-CM diagnosis. No matching diagnosis, no coverage — it's that straightforward.

Cigna defines medical necessity here through the diagnosis pairing, not a separate clinical narrative requirement baked into the policy text. That means your documentation burden lives at the ordering physician level. The diagnosis needs to support the study. The claim needs to reflect that diagnosis accurately.

This coverage policy does not address penile vessel ultrasound or ultrasound used for biopsy guidance. If your team is billing for those services and using 76870, stop. Those services fall outside MM 0548 entirely, and Cigna will not cover them under this policy.

What Conditions Qualify?

The covered indications span a broad clinical range. Here's what Cigna considers medically necessary when paired with CPT 76870:

This is a detailed list. The real billing risk is assuming that "close enough" diagnosis codes will pass. They won't. Cigna's scrotal ultrasound billing adjudication ties directly to this ICD-10 list.

Prior Authorization

The MM 0548 policy text does not specify a prior authorization requirement for CPT 76870. However, prior auth requirements vary by plan and market. Check the specific Cigna plan type — individual, group, or government-sponsored — before assuming prior auth isn't needed. When in doubt, verify with Cigna's authorization team before scheduling.

Reimbursement Implications

If your diagnosis doesn't land on the covered list, reimbursement for CPT 76870 stops at zero. Cigna will deny the claim outright. That makes ICD-10 selection the single biggest lever your billing team controls for this service line.

Cigna Scrotal Ultrasound Exclusions and Non-Covered Indications

MM 0548 draws a clear line around two service types. Cigna will not cover the following under this coverage policy:

#	Excluded Procedure Copy
1	Penile vessel ultrasound — explicitly excluded from MM 0548 scope
2	Ultrasound for biopsy guidance — outside the policy entirely

If your practice performs scrotal-region ultrasound for either of those purposes and bills it as CPT 76870, you're in the wrong policy bucket. Those claims need different code pathways, and billing them under 76870 with the intent to use MM 0548 criteria will generate denials — and could raise audit flags.

Copy Action Items

If your practice bills high volume of CPT 76870 to Cigna and you're unsure how this update intersects with your specific plan contracts, talk to your compliance officer before September 26, 2025. The covered diagnosis list is specific enough that a single mismatch across hundreds of claims adds up fast.
