Adverse effect of unspecified psychostimulants, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to an unspecified psychostimulant medication. These sequelae are permanent or chronic effects that persist after the acute phase of the adverse event has resolved.

Use this code when documenting a patient presenting with a chronic or permanent health problem directly attributable to a previous adverse effect from a psychostimulant, and the specific psychostimulant is not identified. Examples include persistent neurological deficits, chronic psychiatric conditions, or organ damage that developed as a consequence of the earlier adverse drug event.

• Requires a seventh character "S" to indicate sequela, meaning the residual effect of a past adverse event.
• Always sequence this code after the code(s) for the specific sequela or residual condition being treated.
• Ensure documentation clearly links the current condition to a past adverse effect of an unspecified psychostimulant.
