Complete traumatic MCP amputation of left index finger, init

This code signifies the complete severance of the left index finger at the metacarpophalangeal (MCP) joint due to a traumatic event. This means the entire finger, from the knuckle to the fingertip, has been detached from the hand.

Apply this code for patients presenting with a traumatic injury resulting in the full amputation of their left index finger at the MCP joint. This is appropriate for the initial assessment and treatment of such an injury.

• Ensure documentation specifies "complete" amputation and the exact digit (index finger) and side (left).
• Verify the amputation occurred at the metacarpophalangeal joint, not a more distal phalanx.
• The "A" suffix indicates an initial encounter for this specific injury. Subsequent care would use different suffixes.
