Traum rupt of collat ligmt of finger at MCP/IP jt, sequela

This code signifies a long-term complication or late effect resulting from a past traumatic tear of a collateral ligament in any finger other than the thumb, specifically at the knuckle (metacarpophalangeal) or interphalangeal joints. This could include chronic pain, instability, stiffness, or deformity that persists after the initial injury has healed.

Apply this code when documenting a patient presenting with ongoing issues directly attributable to a previously sustained traumatic rupture of a collateral ligament in a finger (excluding the thumb) at the MCP or IP joint. This is appropriate for follow-up visits addressing residual symptoms or complications from the original injury, not the initial acute injury itself.

• Always use this code as a secondary diagnosis, following a code for the specific sequela (e.g., chronic pain, instability).
• Ensure documentation clearly links the current condition to the past traumatic collateral ligament rupture.
• Distinguish from acute injuries, which would use codes without the "S" (sequela) seventh character.
