Frequently asked questions
Which ICD-10 codes support medical necessity for CPT 62321?
Medicare coverage policies (LCDs/NCDs and Billing & Coding articles) list 47 ICD-10 diagnosis codes that support medical necessity for CPT 62321. The covered codes are listed on this page. Coverage varies by MAC/state — always confirm against the policy that applies to you.
