L57.1
ICD-10-CMThis code describes actinic reticuloid, a rare, chronic, and severe form of photosensitivity characterized by persistent, eczematous, or lichenoid skin lesions in sun-exposed areas. It is considered a persistent light reaction, often leading to significant skin thickening and induration.
Use this code when documentation clearly indicates a diagnosis of actinic reticuloid, often confirmed by biopsy and phototesting. This diagnosis is typically made in patients presenting with chronic, exaggerated skin reactions to ultraviolet radiation, even at low exposure levels.
