Partial traumatic MCP amputation of finger, init

This code signifies a traumatic injury where a portion of a finger, excluding the thumb, has been severed at the metacarpophalangeal joint level. This amputation is incomplete, meaning some tissue remains connecting the severed part, but the bone is partially or fully transected. It specifically refers to the initial treatment phase of such an injury.

Apply this code when documenting the initial presentation and treatment of a patient who has sustained a partial traumatic amputation of a finger (index, middle, ring, or little finger) at the knuckle joint. This includes scenarios like industrial accidents, crush injuries, or lacerations that result in an incomplete severing of the digit at this specific joint.

• Ensure the documentation clearly specifies "partial" amputation and the exact finger involved (excluding the thumb).
• Verify the injury occurred at the metacarpophalangeal joint, not the interphalangeal joints.
• Confirm this is the patient's initial encounter for this specific injury to use the "A" seventh character.
