Blister (nonthermal) of left little finger, subs encntr

This code signifies a non-burn related fluid-filled lesion on the little finger of the patient's left hand. It indicates that the patient is presenting for follow-up care or treatment of this specific blister after the initial encounter.

This code is appropriate for subsequent visits related to a blister on the left little finger, such as wound checks, dressing changes, or further evaluation of healing. It should be used when the initial treatment has already been rendered and the patient is returning for ongoing management.

• Ensure documentation specifies "left little finger" and "blister (nonthermal)" for accurate code assignment.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for initial treatment of the blister; a code with an "A" seventh character would be appropriate for the initial encounter.
