Adverse effect of cocaine, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to cocaine. It indicates that the patient is experiencing a persistent health problem directly attributable to a previous adverse effect of cocaine, even if the acute adverse event has resolved. This could include chronic organ damage, neurological deficits, or other lasting sequelae.

Apply this code when documenting a patient's current condition that is a direct consequence of an adverse effect from cocaine use that occurred in the past. This is appropriate for chronic conditions like cocaine-induced cardiomyopathy, persistent neurological deficits following a cocaine-related stroke, or chronic kidney disease linked to a prior adverse cocaine reaction. Do not use for acute adverse effects or current intoxication.

• Always sequence this code after the code for the specific sequela (e.g., I42.7 for cardiomyopathy).
• Ensure documentation clearly links the current condition to a past adverse effect of cocaine.
• Distinguish from current cocaine abuse or dependence, which would be coded separately.
