Blister (nonthermal) of other part of head, init encntr

This code signifies a non-burn related blister located on any part of the head other than the eye or eyelid. It indicates the initial treatment or encounter for this specific injury.

Apply this code for a patient presenting with a newly diagnosed blister on the scalp, ear, nose, or face (excluding ocular structures) caused by friction, pressure, or other non-thermal means. Documentation should clearly specify the blister's location on the head and its non-thermal etiology.

• Ensure the documentation explicitly states "initial encounter" for this specific injury.
• Distinguish from thermal blisters (burns), which are coded differently.
• Confirm the blister is not on the eye or eyelid; those have more specific codes.
