Blister (nonthermal) of right front wall of thorax, init

This code signifies a non-burn related blister located on the anterior aspect of the right chest wall. This lesion is characterized by a fluid-filled sac on the skin, resulting from friction, pressure, or other non-thermal trauma.

Apply this code when documenting a patient's initial presentation for a blister on the right front of the chest, not caused by heat or cold. This would include blisters from tight clothing, repetitive rubbing, or adhesive removal.

• Ensure the blister is explicitly documented as non-thermal and located on the right anterior thorax.
• Verify this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from blisters due to burns (T codes) or frostbite (T codes).
