Anterior subluxation of unsp ulnohumeral joint, sequela

This code indicates a chronic or residual condition resulting from a prior anterior subluxation of the ulnohumeral joint, where the specific side (left or right) is not documented. It signifies a persistent issue or complication stemming from an old injury to the elbow joint, specifically involving the ulna and humerus.

Apply this code when documentation clearly states a sequela (e.g., chronic pain, instability, limited range of motion) due to a previously sustained anterior subluxation of an unspecified ulnohumeral joint. This is appropriate for follow-up encounters addressing long-term effects of the original injury, rather than the initial acute event.

• Requires a seventh character "S" to indicate sequela, signifying a late effect of the injury.
• Only use when the laterality of the affected elbow is not specified in the medical record.
• Do not use for acute or initial encounters of an anterior ulnohumeral subluxation.
