Poisoning by keratolytics, keratoplastics, other hair treatment drugs and preparations

This code signifies an adverse health effect resulting from the ingestion, absorption, or topical application of substances intended for skin or hair treatment, specifically keratolytics, keratoplastics, or other hair preparations. It indicates a toxic reaction or overdose rather than an allergic response or therapeutic failure.

Apply this code when a patient presents with symptoms of poisoning directly attributable to products like salicylic acid, urea, coal tar, or various hair dyes and perms. Documentation should clearly state the substance involved and the resulting toxic effects, such as chemical burns, systemic toxicity, or severe dermatological reactions.

• Always code the specific manifestation of the poisoning (e.g., dermatitis, systemic effects) as an additional diagnosis.
• Distinguish from adverse effects of drugs taken correctly (E930-E949) or allergic reactions (995.3).
• Requires external cause codes (E-codes) to specify the circumstances of the poisoning (e.g., accidental, intentional self-harm).
