Lateral subluxation of left ulnohumeral joint, sequela

This code signifies a persistent or late-effect condition of a partial dislocation of the ulnohumeral joint in the left elbow, where the ulna has shifted laterally relative to the humerus. This indicates that the initial injury has resolved, but the patient continues to experience symptoms or complications directly attributable to that past subluxation.

Apply this code when documenting a patient presenting with ongoing issues such as chronic pain, instability, limited range of motion, or other long-term sequelae stemming from a previously sustained lateral subluxation of their left ulnohumeral joint. This is appropriate when the acute phase of the injury has passed, and the current encounter addresses these lasting effects.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., chronic pain, instability).
• Ensure documentation clearly links the current symptoms or condition to the prior lateral subluxation of the left ulnohumeral joint.
• Verify laterality (left) is explicitly stated in the medical record to support this specific code.
