Lateral subluxation of unsp ulnohumeral joint, sequela

This code signifies a persistent or late-effect lateral displacement of the ulna relative to the humerus, specifically within the elbow joint, where the exact side (left or right) is not documented. It indicates a chronic or residual issue stemming from a previous injury or condition affecting the stability of the ulnohumeral articulation.

Apply this code when documentation clearly states a "sequela" or "late effect" of a lateral subluxation of the ulnohumeral joint, and the laterality is unspecified. This is appropriate for patients presenting with ongoing symptoms or complications directly attributable to a past subluxation, such as chronic pain, instability, or limited range of motion.

• Ensure the documentation explicitly states "sequela" or "late effect" to justify the 7th character 'S'.
• Only use this code when the laterality of the affected elbow is not specified in the medical record.
• Always review the patient's history for the initial injury that led to the subluxation.
