Posterior subluxation of right ulnohumeral joint, sequela

This code indicates a partial dislocation of the right elbow joint, specifically involving the ulna and humerus, where the ulna has shifted backward relative to the humerus. It signifies that this subluxation is a long-term consequence or complication of an initial injury, rather than an acute event. The patient is experiencing ongoing issues directly attributable to this past injury.

Use this code when documenting a patient presenting with persistent symptoms or conditions (e.g., chronic pain, instability, limited range of motion) in the right elbow that are directly linked to a previously sustained posterior ulnohumeral subluxation. This code is appropriate when the initial injury has healed, but its residual effects are still being treated or evaluated.

• Always ensure documentation clearly links the current condition to a past injury.
• Verify laterality (right) and the specific joint involved (ulnohumeral) are explicitly stated.
• Do not use for acute or initial subluxations; reserve for sequela encounters.
