G56.1 — Other lesions of median nerve
Is G56.1 billable?
No — G56.1 is a non-billable header code. G56.1 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 4 billable codes beneath G56.1.

Excludes1 — never code together — inherited from G50-G59
The conditions below can never be reported together with G56.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
