Poisn by keratolyt/keratplst/hair trmt drug, assault, subs

This code signifies a poisoning event resulting from the intentional administration of keratolytics, keratoplastics, or other hair treatment drugs and preparations by another person, where the patient is receiving follow-up care for the sequelae of the initial poisoning. It indicates that the patient is being treated for complications or ongoing effects of the assaultive poisoning, not the initial acute event.

Apply this code when documenting subsequent encounters for a patient who was poisoned by hair treatment products as a result of an assault. This would include visits for managing organ damage, skin lesions, or other systemic effects that developed after the initial poisoning and treatment. Use it for follow-up appointments, rehabilitation, or ongoing medication management related to the assault.

• Always ensure documentation clearly states the poisoning was due to an assault and that this is a subsequent encounter.
• Pair this code with external cause codes (e.g., Y07.-) to fully describe the circumstances of the assault.
• Do not use for the initial acute poisoning episode; that would require an initial encounter (A) or subsequent encounter (D) if the patient is still being actively treated for the acute phase.
