Blister (nonthermal) of other finger, subsequent encounter

This code signifies a non-heat-related fluid-filled lesion on any finger other than the thumb, index, or middle finger. It indicates that the patient is receiving follow-up care for a blister that was previously diagnosed and treated.

Apply this code when a patient presents for subsequent treatment, monitoring, or evaluation of a non-thermal blister on their ring finger or pinky finger. This includes situations like wound care, dressing changes, or assessment of healing progress after the initial encounter.

• Ensure documentation specifies a non-thermal etiology and involvement of the ring or pinky finger.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine follow-up care for the injury.
• Confirm the blister is not due to burns or frostbite, as those would require different codes.
