Poisoning by oth psychostim, accidental, sequela

This code signifies a long-term or late effect resulting from an accidental overdose or adverse reaction to a psychostimulant other than methylphenidate or amphetamines. These sequelae can manifest as chronic neurological, psychiatric, or systemic complications that persist after the acute phase of the poisoning has resolved.

Apply this code when documenting conditions directly attributable to a past, unintentional poisoning by psychostimulants like ecstasy (MDMA), synthetic cathinones ("bath salts"), or other unspecified stimulants. This code is appropriate for follow-up visits addressing residual health problems that are a direct consequence of such an event.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past accidental psychostimulant poisoning.
• Do not use for acute poisoning events; this code is exclusively for sequelae.
