Poisoning by other synthetic narcotics, undetermined, init

This code signifies an adverse health event resulting from exposure to a synthetic narcotic other than fentanyl or tramadol, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is in the active phase of treatment for the poisoning.

Apply this code when a patient presents with symptoms of poisoning from an unspecified synthetic narcotic, and the medical record does not clearly state whether the exposure was accidental, intentional, or due to assault. This code is appropriate for the initial visit or encounter for the poisoning.

• Ensure documentation explicitly states "undetermined" intent for the poisoning.
• Confirm the narcotic involved is a synthetic narcotic, but not fentanyl or tramadol.
• This "A" suffix indicates an initial encounter; use subsequent encounter codes for follow-up care.
