Poisoning by unsp psychostim, accidental, sequela

This code signifies the long-term effects or complications arising from an accidental overdose or exposure to an unspecified psychostimulant. It indicates that the initial poisoning event has resolved, but the patient continues to experience residual health problems directly attributable to that past event.

Apply this code when documenting a patient presenting with chronic conditions, organ damage, or persistent neurological or psychological sequelae that are definitively linked to a prior, unintentional poisoning by a psychostimulant where the specific substance was not identified. This is appropriate for follow-up encounters after the acute phase of the poisoning has passed.

• Requires a seventh character "S" to denote sequela, indicating a complication or residual effect of a previous injury or illness.
• Do not use for acute poisoning events; those require codes with a different seventh character (A or D).
• Always sequence this code after the codes for the specific sequelae being treated (e.g., chronic kidney disease, neurological deficits).
