Subluxation complex (vertebral) of upper extremity

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A partial dislocation of vertebrae in the upper arm and shoulder region that narrows the nerve passages, potentially causing pain or nerve-related symptoms in the arm.

Coding Tips

  • •Distinguish between cervical spine subluxation (M99.21) and upper extremity manifestations of subluxation
  • •Document laterality (right, left, or bilateral) when the subluxation affects one side more than the other
