Poisoning by other synthetic narcotics, self-harm, sequela

This code signifies a long-term consequence or complication arising from a deliberate overdose or self-poisoning with synthetic narcotics other than methadone, fentanyl, or tramadol. These sequelae can manifest as chronic organ damage, neurological deficits, or persistent psychiatric conditions directly attributable to the initial toxic event.

Apply this code when documenting a patient presenting with a current condition that is a residual effect of a past intentional self-harm poisoning by an unspecified synthetic narcotic. This is appropriate for follow-up care, rehabilitation, or management of chronic issues directly linked to the original poisoning.

• Always sequence this code after the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional synthetic narcotic poisoning.
• Do not use for acute poisoning events; this code is exclusively for sequelae.
