Poisoning by unspecified central nervous system stimulant

This code signifies an adverse health event resulting from exposure to a central nervous system (CNS) stimulant where the specific substance involved is not identified. It indicates a toxic effect or overdose from a drug or chemical that increases brain activity, leading to symptoms such as agitation, tachycardia, hypertension, or seizures.

Apply this code when documentation clearly indicates poisoning by a CNS stimulant, but the specific stimulant (e.g., amphetamine, cocaine, caffeine) is not specified by the provider. This is often used in emergency department settings or when initial toxicology screens are pending or non-specific.

• Always attempt to identify the specific CNS stimulant for a more precise code (e.g., 969.7x for amphetamines, 968.5 for cocaine).
• Sequence this code as the primary diagnosis when the poisoning is the reason for the encounter.
• Do not use if the stimulant was prescribed and taken correctly; consider adverse effect codes from E-codes if applicable.
