Traumatic rupture of unsp ulnar collateral ligament, sequela

This code signifies a past injury involving a tear or break in the ulnar collateral ligament (UCL) of the elbow, where the specific location of the tear within the ligament was not documented. The "sequela" designation indicates that this code is used for conditions or complications arising as a direct result of the initial UCL rupture, after the acute phase of the injury has passed.

Apply this code when documenting long-term effects, chronic pain, instability, or other residual issues stemming from a previously sustained, unspecified UCL rupture. This is appropriate for follow-up visits or when a patient presents with ongoing problems related to an old injury. Do not use this code for the initial acute injury.

• Always ensure the documentation clearly states the condition is a sequela of a prior injury.
• Verify that the specific ulnar collateral ligament (e.g., anterior, posterior) was not identified in the original injury documentation.
• Consider using an additional code to specify the nature of the sequela (e.g., chronic pain, instability).
