Posterior subluxation of unsp ulnohumeral joint, sequela

This code signifies a chronic or late-effect condition involving a partial dislocation of the elbow joint, specifically where the ulna has shifted backward relative to the humerus. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to the past subluxation.

Use this code when documenting a patient presenting with ongoing issues such as pain, instability, limited range of motion, or nerve impingement that are a direct consequence of a previously sustained posterior ulnohumeral subluxation. This applies when the acute phase of the injury has passed, and the current encounter addresses these long-term effects.

• The "S" seventh character indicates a sequela, meaning the code is for complications or conditions arising as a direct result of a previous injury.
• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., chronic pain, arthritis, nerve damage).
• Ensure documentation clearly links the current symptoms or condition to a past posterior ulnohumeral subluxation.
