Contusion of left middle finger w damage to nail, subs

This code signifies a bruise to the middle finger of the left hand, specifically involving the nail or nail bed. It indicates that the patient is presenting for follow-up care after the initial injury, such as wound checks, dressing changes, or evaluation of healing.

Apply this code when documenting subsequent encounters for a patient who previously sustained a contusion to their left middle finger with associated nail damage. This includes visits for ongoing management, monitoring for complications, or assessing recovery from the initial injury.

• Ensure documentation specifies "left" middle finger and involvement of the nail.
• Verify the encounter type is "subsequent" (D) and not initial (A) or sequela (S).
• Always code the underlying cause of the injury if known and documented.
