Partial traumatic transmetcrpl amputation of unsp hand, init

This code signifies the traumatic loss of a portion of the hand, specifically through the metacarpal bones, but not involving the wrist joint. It indicates that the amputation is incomplete, meaning some hand tissue or structure distal to the wrist remains. The "unspecified hand" modifier means the laterality (left or right) is not documented.

Apply this code for initial encounters when a patient presents with a traumatic injury resulting in a partial amputation through the metacarpals. This would include scenarios where the hand is severed distal to the carpals but proximal to the phalanges, and the injury is fresh or the patient is receiving initial treatment.

• Ensure documentation specifies a partial amputation through the metacarpals, not a complete hand amputation or amputation at a different level.
• Verify that the encounter is the initial treatment for this specific injury; subsequent encounters will require a different seventh character.
• Look for documentation of laterality (left or right hand) to select a more specific code if available.
