Complete traumatic transphalangeal amputation of thmb, init

This code signifies the complete severance of an unspecified thumb at any point along its length due to a traumatic event. This injury involves the entire thickness of the digit, including bone, soft tissue, and nail, resulting in a total loss of the distal portion.

Apply this code for initial treatment encounters of patients presenting with a traumatic amputation where the thumb has been entirely detached. This includes cases resulting from industrial accidents, machinery injuries, or other acute trauma.

• Ensure documentation specifies "complete" and "transphalangeal" to support this code.
• Verify laterality (left or right) is not specified in the medical record; if it is, a more specific code should be used.
• Confirm this is the patient's first encounter for this specific injury. Subsequent care would require a different encounter character.
