Subluxation of distal end of left ulna, subsequent encounter

This code signifies a partial dislocation of the radioulnar joint at the wrist, specifically involving the distal end of the left ulna. It indicates that the patient is receiving follow-up care for this injury after the initial treatment phase.

This code is appropriate for encounters where a patient is being seen for ongoing management, rehabilitation, or complications related to a previously diagnosed subluxation of the distal left ulna. This includes visits for physical therapy, re-evaluation, or cast changes following the initial injury.

• Ensure documentation clearly specifies the left side and the "subsequent encounter" status.
• Pair with an external cause code (V00-Y99) if the cause of the original injury is known and relevant to the current encounter.
• Do not use for the initial treatment of the injury; refer to the "initial encounter" code for that scenario.
