Partial traumatic MCP amputation of left middle finger, subs

This code signifies a partial traumatic amputation of the metacarpophalangeal (MCP) joint of the left middle finger. This means a portion of the finger, specifically at the knuckle connecting the finger to the hand, was severed due to an injury, but not the entire finger.

This code is used for follow-up care of a patient who previously sustained this specific injury. This includes subsequent visits for wound care, physical therapy, monitoring for complications, or fitting for a prosthetic. It should not be used for the initial encounter of the injury.

• Ensure documentation specifies "partial" amputation and the exact finger (middle) and hand (left).
• Verify the encounter is for subsequent care, not the initial treatment of the injury.
• Confirm the injury site is the metacarpophalangeal joint, not the interphalangeal joints.
