Poisoning by other topical agents, assault, subs encntr

This code signifies a poisoning event resulting from the intentional harm caused by another person using a topical agent not otherwise specified. The patient is presenting for follow-up care, monitoring, or treatment of residual effects after the initial acute phase of the poisoning.

Apply this code when documenting subsequent care for a patient who was poisoned via assault with a topical agent such as a chemical irritant, unknown ointment, or other substance applied to the skin or mucous membranes by another individual. This includes visits for wound care, dermatological follow-up, or management of systemic effects after the initial presentation.

• Always sequence this code after the primary injury or manifestation of the poisoning.
• Ensure documentation clearly specifies the "assault" intent and the "subsequent encounter" for ongoing care.
• A fifth character of 'X' is used when the specific topical agent is not identified.
