Traum rupture of collat ligmt of finger at MCP/IP jt, subs

This code indicates a traumatic tear of a collateral ligament in any finger other than the thumb, affecting either the metacarpophalangeal (MCP) or interphalangeal (IP) joint. This injury typically results from a sudden force or hyperextension to the finger joint, leading to instability and pain.

This code is used for follow-up encounters for patients receiving active treatment for a previously diagnosed traumatic collateral ligament rupture of a finger (excluding the thumb). This includes visits for cast changes, physical therapy, wound care, or monitoring healing progress after initial treatment. It is also appropriate for subsequent encounters related to surgical repair of such an injury.

• Confirm the encounter is for active treatment of a previously diagnosed injury, not the initial encounter.
• Verify the injury involves a collateral ligament of a finger other than the thumb and specifies either the MCP or IP joint.
• Ensure the documentation supports the "subsequent encounter" character (D) for ongoing care.
