Sunburn of first degree

This code signifies a mild sunburn characterized by erythema, pain, and tenderness without blistering or skin loss. It indicates superficial damage to the epidermis resulting from overexposure to ultraviolet radiation.

Apply this code when documentation specifies a first-degree sunburn, often described as redness and discomfort. This diagnosis is appropriate for acute, non-blistering solar dermatitis.

• Differentiate from second-degree sunburns (L55.1) which involve blistering.
• Ensure documentation clearly states "first degree" or describes symptoms consistent with superficial erythema.
• Do not use for chronic sun damage or other forms of dermatitis.
