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

This code signifies a traumatic tear of a collateral ligament in the left ring finger, affecting both the metacarpophalangeal (MCP) and interphalangeal (IP) joints. This injury typically results in instability and pain in the affected finger.

Apply this code for follow-up encounters when a patient is receiving active treatment for a previously diagnosed traumatic rupture of the collateral ligament in their left ring finger, involving both the MCP and IP joints. This includes subsequent visits for cast changes, physical therapy, or medication management during the healing phase.

• Ensure the documentation specifies a traumatic rupture, not an atraumatic or degenerative tear.
• Verify that the injury is specifically to the collateral ligament of the left ring finger and involves both the MCP and IP joints.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is still receiving active treatment for the injury.
