T22.5 — Corrosion of first degree of shoulder and upper limb, except wrist and hand
T22.5 is a non-billable header ICD-10-CM code for corrosion of first degree of shoulder and upper limb, except wrist and hand. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

Excludes2 inherited from the categories above T22.5
Also inherited, and the opposite of Excludes1: these conditions are not part of T22.5, but a patient can have both, so you may code both.
Risk adjustment
T22.5 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
T22.5 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
