Polymorphous light eruption

This code identifies a chronic, recurrent, and often itchy skin rash that appears hours or days after sun exposure. It is characterized by various lesion types, including papules, vesicles, plaques, and eczematous patches, primarily affecting sun-exposed areas.

Assign this code when documentation clearly indicates a diagnosis of polymorphous light eruption. This typically occurs after a patient presents with characteristic skin lesions following sun exposure, and other photosensitivity disorders have been ruled out.

• Ensure documentation specifies "polymorphous light eruption" to differentiate from other photodermatoses.
• Do not confuse with solar urticaria or other forms of photosensitivity dermatitis.
• Consider any associated symptoms or complications for additional coding, if documented.
