Blister (nonthermal) of left little finger, init encntr

This code signifies a non-burn related blister located specifically on the little finger of the left hand. This injury involves the superficial separation of skin layers, resulting in a fluid-filled lesion, and is documented as the initial presentation of the condition.

Apply this code for patients presenting with a newly diagnosed blister on their left little finger, not caused by heat or cold exposure. This includes blisters resulting from friction, chemical irritants, or other mechanical trauma.

• Ensure documentation specifies "left little finger" and "blister" (nonthermal).
• Confirm this is the patient's first encounter for this specific injury.
• Do not use for blisters caused by burns or frostbite; those have different code categories.
