Traum rupt of collat ligmt of r lit fngr at MCP/IP jt, init

This diagnosis code signifies an acute, traumatic tear of a collateral ligament in the right little finger, affecting either the joint connecting the finger to the hand (metacarpophalangeal) or the joints within the finger itself (interphalangeal). This injury typically results in pain, swelling, and instability of the affected joint.

Use this code for initial encounters when a patient presents with a newly sustained injury involving a collateral ligament rupture in the right little finger due to trauma. This includes injuries from sports, falls, or direct impact to the finger. It is appropriate for the initial evaluation and treatment of the acute injury.

• Ensure documentation clearly specifies "traumatic rupture" and the specific finger (right little finger).
• Verify the encounter is "initial" for the injury; subsequent care will require a different seventh character.
• Distinguish between collateral ligament injuries and other ligamentous or tendinous injuries of the finger.
