Partial traumatic MCP amputation of finger, sequela

This code signifies a partial traumatic amputation of a metacarpophalangeal (MCP) joint of any finger other than the thumb, which has resulted in a sequela. A partial amputation means that some tissue remains, but the joint integrity is compromised due to the traumatic event. The "sequela" indicates that this code is used for the long-term effects or complications of the initial injury, not the acute injury itself.

Use this code for patients presenting with chronic issues, deformities, or functional limitations directly resulting from a past partial traumatic MCP amputation of a finger other than the thumb. This applies when the initial injury has healed, and the patient is now being treated for the residual effects. Examples include ongoing pain, stiffness, or the need for reconstructive surgery years after the initial trauma.

• Ensure the documentation clearly states "partial" amputation and specifies the MCP joint of a finger other than the thumb.
• Confirm that the encounter is for a sequela (late effect) of the injury, not the initial acute trauma.
• Always code an external cause code (V00-Y99) in conjunction with this code to describe the circumstances of the original injury.
