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

This code signifies a poisoning event involving keratolytics, keratoplastics, or other hair treatment drugs and preparations, where the intent (accidental, intentional self-harm, assault) cannot be determined. This specific code is used for encounters following the initial treatment of the poisoning.

Use this code when a patient presents for follow-up care, such as monitoring for delayed effects, managing complications, or further treatment, after an initial poisoning by hair treatment products. The original poisoning event must have had an undetermined intent.

• Always assign an additional code for the specific manifestation of the poisoning.
• Ensure the "D" seventh character is appropriate for subsequent encounters after initial active treatment.
• Distinguish carefully between undetermined intent and accidental or intentional poisonings, as different codes apply.
