Poisoning by unsp antipsychot/neurolept, assault, subs

This code signifies a patient presenting for follow-up care or sequelae related to an intentional overdose or exposure to an unspecified antipsychotic or neuroleptic medication, inflicted by another person. The initial acute phase of the poisoning has passed, and the patient is now being managed for ongoing effects or complications.

This code is appropriate for subsequent encounters when a patient is receiving ongoing treatment for the effects of an antipsychotic or neuroleptic poisoning that was determined to be an assault. Examples include follow-up appointments for organ damage, neurological deficits, or psychiatric complications resulting from the initial event. It should be used after the initial acute treatment has concluded.

• Ensure documentation clearly states the poisoning was an assault and that this is a subsequent encounter.
• Always sequence this code after any codes for specific manifestations or complications of the poisoning.
• Do not use for initial acute care; refer to the appropriate initial encounter code for the acute phase.
