Partial traumatic MCP amputation of thmb, init

This code signifies a traumatic injury resulting in the partial loss of the thumb at the metacarpophalangeal (MCP) joint, where some soft tissue or bone remains. It specifically refers to an injury where the thumb is not completely severed but has sustained significant traumatic damage at this joint level.

Use this code for initial encounters with patients presenting with a traumatic partial amputation of an unspecified thumb at the MCP joint. This includes scenarios such as crush injuries, avulsions, or lacerations that result in incomplete severance of the thumb at this specific anatomical location.

• Ensure documentation clearly specifies "partial" amputation and the "metacarpophalangeal" joint level.
• Verify the encounter is the "initial" treatment for this specific injury.
• If the laterality (left or right thumb) is known, a more specific code should be used.
