Poisoning by other synthetic narcotics, accidental, subs

This code signifies a poisoning event resulting from the accidental or unintentional ingestion, exposure, or overdose of synthetic narcotics other than methadone, fentanyl, or tramadol. It indicates that the patient is receiving follow-up care for the sequelae of this poisoning, such as ongoing treatment for organ damage, withdrawal symptoms, or rehabilitation.

Apply this code when a patient presents for subsequent treatment related to an accidental poisoning by a synthetic narcotic not specified elsewhere (e.g., meperidine, propoxyphene). This includes scenarios where the patient is admitted for complications arising from the initial poisoning or is receiving ongoing management in an outpatient setting after the acute phase.

• Ensure the documentation clearly states the poisoning was accidental and identifies the substance as a synthetic narcotic other than methadone, fentanyl, or tramadol.
• This "D" seventh character is for subsequent encounters, meaning the patient is receiving routine care during the healing or recovery phase.
• Always sequence this code after any codes for the specific manifestations of the poisoning (e.g., respiratory depression, acute kidney injury).
