Adverse effect of keratolyt/keratplst/hair trmt drug, subs

This code signifies a patient experiencing an unintended and harmful reaction from the therapeutic use of medications or preparations designed to treat skin conditions involving keratin (e.g., salicylic acid, urea) or for hair treatment. The adverse effect is occurring during a follow-up visit after initial treatment for the reaction.

Apply this code when a patient presents for ongoing management or evaluation of an adverse reaction to keratolytics, keratoplastics, or hair treatment drugs, such as contact dermatitis, chemical burns, or systemic toxicity, after the initial treatment has been rendered. This indicates that the adverse effect is still being addressed or monitored.

• Always sequence this code after the code identifying the specific manifestation of the adverse effect (e.g., contact dermatitis).
• Ensure the documentation clearly states the adverse effect is due to a therapeutic agent from the specified drug class.
• Verify that the encounter is for follow-up care of the adverse effect, not the initial presentation.
