CPT G2251: ICD-10 codes that support medical necessity
These ICD-10-CM diagnoses support medical necessity for CPT G2251 under Medicare coverage policies (LCDs, NCDs, and Billing & Coding articles). Billing CPT G2251 with a diagnosis that isn't covered typically denies as CARC 50 — not medically necessary.
National approximation. Coverage varies by MAC and state — confirm against the specific LCD/NCD and article that applies to your jurisdiction and date of service.

Frequently asked questions
Which ICD-10 codes support medical necessity for CPT G2251?
Medicare coverage policies (LCDs/NCDs and Billing & Coding articles) list 14836 ICD-10 diagnosis codes that support medical necessity for CPT G2251. The covered codes are listed on this page. Coverage varies by MAC/state — always confirm against the policy that applies to you.
What is a medical-necessity (LCD/NCD) crosswalk?
A claim whose procedure isn't supported by a covered diagnosis denies as "not medically necessary" (CARC 50). CMS coverage policies define which diagnoses justify a procedure; this page is the ICD-10 → CPT G2251 view of that relationship.
Catch medical-necessity denials before you bill. CareNiva scrubs claims against LCD/NCD coverage and flags unsupported diagnoses — in the same platform you run visits and billing.
