Poisn by keratolyt/keratplst/hair trmt drug, asslt, sequela

This code signifies a long-term health condition or complication arising from a past intentional poisoning by substances used to treat skin or hair, such as salicylic acid, urea, or minoxidil. The original poisoning event was a deliberate act of harm by another person. The sequela could manifest as persistent skin damage, organ dysfunction, or neurological issues.

Apply this code when documenting a patient's current condition that is a direct consequence of an assault involving keratolytics, keratoplastics, or other hair treatment drugs and preparations. This code is appropriate for chronic or residual effects that are no longer in the acute phase of poisoning. It should be used after the initial poisoning has been treated and the patient is presenting for follow-up care related to the lasting impact.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic dermatitis, kidney damage).
• Ensure documentation clearly links the current condition to a past assault by the specified substances.
• Do not use for acute poisoning events; this code is exclusively for sequelae.
