Blister (nonthermal) of penis, initial encounter

This code signifies a non-burn related fluid-filled lesion on the penis. It indicates the very first instance or presentation of this specific condition. The blister is not caused by heat, cold, or chemical exposure.

Apply this code when documenting a patient's initial visit for a new, non-thermal blister on the penis. This includes blisters resulting from friction, allergic reactions, or other non-burn etiologies. It is appropriate for the acute phase of treatment.

• Ensure documentation clearly states the blister is non-thermal and located on the penis.
• Confirm this is the patient's first encounter for this specific blister; subsequent encounters will use a different seventh character.
• Always review the medical record for the underlying cause of the blister, as additional codes may be necessary.
