Complete traumatic MCP amputation of thmb, subs

This code signifies the complete severance of an unspecified thumb at the metacarpophalangeal joint due to a traumatic event. The amputation involves the entire thumb distal to this joint, indicating a full loss of the digit. This specific code is used for encounters following the initial treatment of the injury.

This code is appropriate for follow-up visits, such as wound care, physical therapy, or prosthetic fitting, after the initial surgical management of a complete traumatic thumb amputation at the MCP joint. It should be used when the patient is seen for ongoing care related to the original injury, not for the initial presentation.

• Ensure documentation clearly states "complete" amputation and specifies the metacarpophalangeal joint of the thumb.
• Verify this is a "subsequent encounter" and not the initial treatment for the injury.
• If the laterality (left or right thumb) is documented, a more specific code should be used.
