Laceration of blood vessel of left little finger, subs

This code signifies a cut or tear to a blood vessel within the little finger of the left hand, specifically when the patient is presenting for follow-up care after the initial injury. It indicates that the injury is not new but rather being managed in a subsequent encounter.

Apply this code for patients returning for wound checks, dressing changes, or evaluation of healing progress following an initial laceration to a blood vessel in the left little finger. This includes scenarios where the initial treatment has already been rendered and the patient is in a recovery phase.

• Ensure documentation clearly specifies the left little finger and involvement of a blood vessel.
• The "D" seventh character indicates subsequent care; do not use for the initial treatment of the injury.
• Always code the underlying cause of the laceration (e.g., W25.XXXD for contact with sharp glass) as an external cause code.
