CPT 95999: ICD-10 codes that support medical necessity
These ICD-10-CM diagnoses support medical necessity for CPT 95999 under Medicare coverage policies (LCDs, NCDs, and Billing & Coding articles). Billing CPT 95999 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.

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 95999 view of that relationship.
