Frequently asked questions
Which ICD-10 codes support medical necessity for CPT 36476?
Medicare coverage policies (LCDs/NCDs and Billing & Coding articles) list 78 ICD-10 diagnosis codes that support medical necessity for CPT 36476. 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 36476 view of that relationship.
