Poisoning by oth psychostimulants, undetermined, init encntr

This code signifies an adverse effect resulting from the ingestion of a psychostimulant other than amphetamines, such as methylphenidate or modafinil, where the intent (e.g., accidental, intentional self-harm) cannot be determined. The patient is in the acute phase of treatment for this poisoning.

Apply this code when a patient presents with symptoms of poisoning from a non-amphetamine psychostimulant, and the provider's documentation does not specify whether the exposure was accidental, intentional, or assault. This is used for the initial encounter for treatment of the poisoning.

• Requires documentation of "undetermined" intent for the poisoning.
• An additional code for the specific psychostimulant, if known, is not required as this code covers "other psychostimulants."
• The "A" seventh character indicates the initial encounter for this condition. Subsequent encounters would use "D" or "S."
