Ulnar collateral ligament sprain of unsp elbow, init encntr

This code signifies a sprain of the ulnar collateral ligament (UCL) in an elbow where the specific side (right or left) is not documented. A UCL sprain involves stretching or tearing of the ligament that stabilizes the inner aspect of the elbow joint, often resulting from repetitive valgus stress or a sudden forceful movement.

This code is appropriate for the initial encounter of a patient presenting with symptoms consistent with a UCL sprain, such as medial elbow pain, tenderness, and instability, when the medical record does not specify which elbow is affected. It is used when the provider has not yet determined or documented laterality.

• Always strive for laterality (right or left) if documented; only use this code when laterality is truly unspecified.
• Ensure the "A" seventh character for "initial encounter" is appropriate for the patient's first visit for this specific injury.
• If the encounter is for subsequent care or sequelae, a different seventh character will be required.
