Partial traumatic MCP amputation of finger, subs

This code signifies a partial loss of an "other" finger (not the thumb or index finger) at the metacarpophalangeal (MCP) joint due to trauma. "Partial" indicates that some portion of the finger beyond the MCP joint remains. This diagnosis is used during the healing or recovery phase after the initial injury.

Apply this code when documenting follow-up care for a patient who previously sustained a traumatic partial amputation of their middle, ring, or little finger at the MCP joint. This includes scenarios such as wound care, physical therapy, or monitoring for complications during the healing process. It is appropriate for any encounter after the initial treatment of the acute injury.

• Ensure the documentation specifies "partial" amputation and identifies the affected finger as one other than the thumb or index finger.
• Confirm the encounter is for subsequent care, not the initial treatment of the injury.
• Pair with external cause codes (V, W, X, Y categories) to describe the circumstances of the injury, if known and relevant to the encounter.
