Complete traumatic trnsphal amputation of l idx fngr, init

This code signifies the complete traumatic severance of the left index finger through the bone, rather than a soft tissue injury. It specifically indicates that the amputation is full thickness, involving all tissues including bone, and is the initial presentation for this injury.

Apply this code for patients presenting with a traumatic injury resulting in the complete loss of their left index finger. This would be used in emergency department settings, urgent care, or initial physician office visits following such an injury. It is crucial to use this code only for the initial encounter of this specific injury.

• Ensure documentation specifies "complete" and "transphalangeal" to support the use of this code.
• Verify the laterality (left) and digit (index finger) are accurately documented.
• The "A" seventh character indicates an initial encounter; subsequent care would require different seventh characters.
