Z74.0 — Reduced mobility
Z74.0 is a non-billable header ICD-10-CM code for reduced mobility. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 inherited from the categories above Z74.0
Also inherited, and the opposite of Excludes1: these conditions are not part of Z74.0, but a patient can have both, so you may code both.
Other codes that can never be billed with Z74.0
These codes carry an Excludes1 note pointing at Z74.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z74.0 alone.

Risk adjustment
Z74.0 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
Z74.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
