Ulnar collateral ligament sprain of left elbow, sequela

This code describes a chronic or residual condition resulting from an injury to the ulnar collateral ligament (UCL) in the left elbow. It indicates that the initial sprain has healed, but the patient continues to experience long-term effects such as instability, pain, or functional limitation related to that original injury.

Apply this code when documenting a patient presenting with persistent symptoms or complications directly attributable to a past ulnar collateral ligament sprain of the left elbow. This is appropriate for follow-up visits addressing chronic pain, instability, or reduced range of motion that are sequelae of the initial sprain, even if the acute injury itself occurred months or years prior.

• Always use this code as a secondary diagnosis, following a code for the specific sequela (e.g., chronic pain, instability).
• Ensure documentation clearly links the current symptoms to a previously sustained left elbow UCL sprain.
• Do not use for acute or subacute sprains; those require codes from the acute injury section.
