CPT 97542: ICD-10 codes that support medical necessity

27004 covered diagnosis codes under Medicare coverage policies (LCD/NCD)

These ICD-10-CM diagnoses support medical necessity for CPT 97542 under Medicare coverage policies (LCDs, NCDs, and Billing & Coding articles). Billing CPT 97542 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 97542?

Medicare coverage policies (LCDs/NCDs and Billing & Coding articles) list 27004 ICD-10 diagnosis codes that support medical necessity for CPT 97542. 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 97542 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.

Informational only, not coding, billing, or legal advice. Based on CMS Medicare Coverage Database data; verify the current LCD/NCD for your MAC before billing.
