Poisoning by keratolyt/keratplst/hair trmt drug, undet, init

This code signifies an accidental or intentional poisoning by substances used in hair treatments, such as those that soften or harden keratin, or other hair preparations. The specific nature of the poisoning (e.g., ingestion, topical exposure) is not specified, but the key is exposure to these agents leading to a toxic effect.

This code is appropriate when a patient presents with symptoms of poisoning following exposure to hair treatment products, and the intent (accidental vs. intentional) cannot be determined at the time of the initial encounter. Examples include a child ingesting a hair relaxer or an adult experiencing an adverse systemic reaction after using a hair dye, where the intent of exposure is unclear.

• Always use an additional code to specify the specific substance if known (e.g., from the T51-T65 range).
• Remember the 7th character 'A' indicates an initial encounter for active treatment of the poisoning.
• If the intent is later determined (accidental, intentional self-harm, assault), update the 7th character accordingly for subsequent encounters.
