Poisoning by unspecified psychostimulants, assault, sequela

This code signifies a long-term health consequence or complication arising from an intentional act of poisoning by an unknown or unclassified psychostimulant. The original poisoning event was perpetrated by another individual with intent to harm. The patient is no longer experiencing the acute effects of the poisoning but is presenting for care related to its lasting impact.

Apply this code when documenting a sequela (e.g., chronic organ damage, neurological deficits, persistent psychiatric conditions) directly attributable to a past assault involving an unspecified psychostimulant. This code is appropriate for follow-up visits or admissions where the primary reason for care is the management of these chronic effects, long after the acute poisoning episode has resolved.

• Always assign an additional code(s) to specify the particular sequela being treated (e.g., G92 for toxic encephalopathy).
• Ensure documentation clearly links the current condition to the past assault and specifies the substance as an unspecified psychostimulant.
• This "S" seventh character indicates a sequela and should only be used for complications or conditions that arise as a direct result of the initial injury or poisoning.
