Poisoning by other synthetic narcotics, self-harm, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from an intentional overdose or self-poisoning with a synthetic narcotic other than methadone, fentanyl, or tramadol. The initial act of self-harm has already occurred, and the patient is now receiving ongoing management for its effects.

Apply this code when documenting subsequent encounters for patients who previously attempted suicide or intentionally harmed themselves by ingesting or administering an unspecified synthetic narcotic. This includes visits for managing organ damage, psychiatric evaluation, or other sequelae directly related to the initial poisoning event.

• Ensure documentation clearly states the intent was self-harm, not accidental or assault.
• Verify the specific synthetic narcotic involved is not methadone, fentanyl, or tramadol, as those have more specific codes.
• This "D" seventh character indicates a subsequent encounter; use "A" for initial encounters and "S" for sequelae.
