Traumatic rupture of left ulnar collateral ligament, subs

This diagnosis code indicates a tear of the ulnar collateral ligament (UCL) in the left elbow that occurred due to an injury. It specifically applies when the patient is receiving follow-up care for the initial injury, such as cast changes, physical therapy, or medication management after the acute phase of treatment.

Apply this code for patients presenting for ongoing treatment of a previously diagnosed traumatic rupture of the left elbow UCL. This includes visits for rehabilitation, monitoring of healing, or management of complications after the initial injury and definitive treatment. Do not use for the initial encounter where the injury was first diagnosed.

• Ensure documentation clearly specifies "left" elbow and a "traumatic rupture" of the UCL.
• Confirm the encounter is for follow-up care, not the initial injury or a new injury.
• Always sequence this code after any definitive treatment codes if applicable.
