Traum rupt of collat ligmt of l lit fngr at MCP/IP jt, subs

This code signifies a traumatic tear of a collateral ligament in the left little finger, affecting both the metacarpophalangeal (MCP) and interphalangeal (IP) joints. This injury typically results from a forceful hyperextension or abduction/adduction stress to the finger. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed injury.

Use this code for patients presenting for ongoing treatment, such as cast changes, physical therapy, or medication management, after an initial diagnosis of a collateral ligament rupture in the left little finger. It is appropriate for encounters following the acute phase of injury, but before the injury is fully healed.

• Ensure documentation specifies "left little finger" and involvement of both MCP and IP joints.
• Confirm the encounter type is "subsequent" (D) and not initial (A) or sequela (S).
• Verify the injury is explicitly described as a "rupture" or "tear" of the collateral ligament.
