Complete traumatic trnsphal amputation of left thumb, init

This code signifies the complete traumatic severance of the entire left thumb, including all phalanges, due to an injury. It indicates that the thumb is entirely detached from the hand. This specific code is for the initial encounter for treatment of this severe injury.

Use this code for patients presenting with a fresh, traumatic amputation where the left thumb is entirely missing. This applies to emergency department visits, initial surgical consultations, or the first inpatient admission directly related to the injury. It should be selected when the injury is acute and the patient is receiving initial care.

• Ensure documentation specifies "complete" and "transphalangeal" to support the severity of the amputation.
• Verify the laterality is explicitly "left thumb" and not another digit or hand.
• Confirm this is the "initial encounter" for treatment; subsequent care will require a different seventh character.
