Poisoning by other synthetic narcotics, assault, subs

This code signifies a patient presenting for follow-up care or treatment of complications resulting from an intentional overdose or poisoning by a synthetic narcotic other than tramadol, fentanyl, or other specified synthetic narcotics. The poisoning was inflicted by another individual with intent to harm.

Use this code for subsequent encounters when a patient is receiving ongoing care for the effects of an assault-related poisoning by an unspecified synthetic narcotic. This includes follow-up appointments for organ damage, psychological trauma, or chronic pain management directly attributable to the initial poisoning event. It is appropriate after the initial acute phase of treatment.

• Ensure documentation clearly states the poisoning was due to an assault and involves a synthetic narcotic not otherwise specified.
• Confirm this is a subsequent encounter, indicating care after the initial acute treatment.
• Always sequence this code after any codes for the specific manifestations or complications of the poisoning.
