Subluxation of MCP joint of left middle finger, subs

This code describes a partial dislocation of the joint connecting the metacarpal bone to the first bone of the left middle finger. The joint surfaces are no longer perfectly aligned, but they remain in partial contact. This injury typically results in pain, swelling, and limited range of motion in the affected finger.

Use this code for follow-up encounters when a patient is receiving active treatment for a previously diagnosed subluxation of the left middle finger's metacarpophalangeal joint. This includes visits for physical therapy, re-evaluation of conservative management, or post-operative care during the healing phase. It is appropriate for any encounter after the initial treatment has been rendered.

• Ensure documentation clearly specifies "subsequent encounter" for ongoing care of the injury.
• Verify the laterality (left) and specific finger (middle) are accurately documented.
• Do not use for initial treatment of the injury; a different 7th character would be required.
