Transvaginal Ultrasound, Non-Obstetrical - (0398) — MM 0398 | CIGNA Coverage Update

Cigna Healthcare modified MM 0398, the transvaginal ultrasound coverage policy for CPT 76830, effective February 22, 2026. Here's what billing teams need to know.

Cigna Healthcare updated its non-obstetrical transvaginal ultrasound billing policy under MM 0398 — the coverage policy governing CPT 76830. This change affects gynecology, OB/GYN, and women's health practices that bill Cigna for TVUS procedures used in evaluating gynecologic disorders and cancer screening. If your team bills CPT 76830 to Cigna, audit your ICD-10 pairings now — 148 diagnosis codes are in scope, and the wrong pairing means a claim denial.

Quick-Reference Table

Cigna Transvaginal Ultrasound Coverage Criteria and Medical Necessity Requirements 2026

The Cigna transvaginal ultrasound coverage policy under MM 0398 covers CPT 76830 for non-obstetrical indications when medical necessity criteria are met. The policy specifically addresses TVUS used in the evaluation of gynecologic disorders and cancer screening. Coverage hinges on the diagnosis code you submit — Cigna has defined 148 ICD-10-CM codes that support medical necessity for this procedure.

That's not a small list. But it's also not a blank check. Cigna will deny CPT 76830 claims where the submitted diagnosis doesn't appear in the covered ICD-10 set. Your documentation must support the specific diagnosis code — not just the clinical decision to perform the scan.

Prior authorization requirements under MM 0398 vary by plan type. Check your specific Cigna contract and plan tier before scheduling the procedure, not after. If you're unsure whether a specific Cigna plan requires prior auth for CPT 76830, call the plan directly — the administrative cost of that call is nothing compared to a retroactive denial.

Reimbursement for CPT 76830 under Cigna depends on medical necessity being clearly established in the clinical record. The code itself isn't the issue. The diagnosis pairing is where claims fall apart. Cigna's updated coverage policy makes that pairing framework explicit — 148 ICD-10 codes are listed, and anything outside that list puts your claim at risk.

Cigna Transvaginal Ultrasound Exclusions and Non-Covered Indications

The policy's focus on gynecologic disorders and cancer screening signals where Cigna draws the line. Obstetrical indications are explicitly outside the scope of MM 0398 — this policy is non-obstetrical only. Bill pregnancy-related TVUS under the appropriate obstetric ultrasound codes, not CPT 76830.

Claims for CPT 76830 paired with diagnosis codes outside the 148 covered ICD-10-CM codes will face denial. The real issue here is diagnosis specificity. Submitting a vague or unspecified code — when a more specific diagnosis code is available and documented — is the fastest way to trigger a claim denial under this policy.

Cigna Transvaginal Ultrasound Billing Guidelines and Action Items 2026

If your practice has a high volume of Cigna transvaginal ultrasound billing, talk to your compliance officer before the February 22, 2026 effective date. The breadth of the ICD-10 list creates opportunity, but it also creates audit exposure if your documentation doesn't consistently support the codes you're submitting.

Key ICD-10-CM Diagnosis Codes

This is the complete MM 0398 code set from Cigna's policy. Every CPT 76830 claim you submit to Cigna needs to pair with one of these codes — or a code from the full 148-code list.

The full MM 0398 policy includes 148 ICD-10-CM codes. The complete list is available in the Cigna policy document. View the full policy on PayerPolicy →

One thing worth flagging: the inclusion of breast disorder codes (the entire N60–N64 range) and mammographic finding codes (R92.0–R92.2) alongside gynecologic indications is unusual. Transvaginal ultrasound doesn't image breast tissue. If Cigna's policy lists these codes as covered paired diagnoses, your clinical documentation should explain the clinical rationale clearly. Submit those claims with supporting notes. A denial prevention review from your compliance officer is worth the time if breast-disorder codes appear in your CPT 76830 billing patterns.
