Exposure to sunlight, sequela

This code signifies a long-term or late-developing health problem resulting from a past exposure to sunlight. It indicates that the current condition is a residual effect of a previous sun-related injury or overexposure, rather than an acute event.

Apply this code when documenting conditions such as chronic actinic dermatitis, solar elastosis, or certain types of skin cancer that are directly attributed to historical sun exposure. It is appropriate when the acute phase of the sun exposure has passed, and the patient is presenting with a lasting consequence.

• Always sequence this code after the code for the specific sequela (e.g., the type of skin cancer or dermatosis).
• Ensure documentation clearly links the current condition to a past history of sun exposure.
• Do not use for acute sunburns or immediate reactions to sun exposure; those require acute injury codes.
