S53.124 is a non-billable header ICD-10-CM code for posterior dislocation of right ulnohumeral joint. 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.

These are not written on S53.124, but they bind it: a note on a category applies to every code beneath it. Billing S53.124 with anything listed here is a denial.

Written on S53.1 — Subluxation and dislocation of ulnohumeral joint

dislocation of radial head alone (S53.0-)

Excludes2 inherited from the categories above S53.124

Also inherited, and the opposite of Excludes1: these conditions are not part of S53.124, but a patient can have both, so you may code both.

Written on S53 — Dislocation and sprain of joints and ligaments of elbow

strain of muscle, fascia and tendon at forearm level (S56.-)

Risk adjustment

S53.124 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.

S53.124 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
