Blister of face, neck, and scalp except eye, without mention of infection

This code signifies the presence of a fluid-filled lesion (blister) on the skin of the face, neck, or scalp, excluding the eye region. It specifically indicates that there is no documented evidence of infection associated with the blister.

Use this code when documentation clearly identifies a non-infected blister located on the face, neck, or scalp. This would include conditions like friction blisters, contact dermatitis with blistering, or thermal burns resulting in blisters, provided infection is not present. Documentation should specify the anatomical location and the absence of infection.

• Ensure the documentation explicitly states "without infection" or similar phrasing; otherwise, a code indicating infection may be more appropriate.
• Differentiate from codes for burns (940.x-949.x) if the blister is a direct result of a burn, as the burn code would take precedence.
• Do not use for blisters involving the eye; refer to codes within the 920-922 range for eye injuries.
