Poisoning by unsp narcotics, undetermined, init encntr

This code signifies a case of poisoning due to an unspecified narcotic substance where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined. It is used for the initial encounter when the patient is actively receiving treatment for the acute effects of the poisoning.

Apply this code when a patient presents with symptoms of narcotic poisoning, and the specific narcotic agent involved is unknown or not documented. This is also appropriate when the circumstances surrounding the poisoning are unclear, and the patient is undergoing initial evaluation and management in an emergency department or inpatient setting.

• Ensure documentation clearly states "unspecified narcotic" and "undetermined intent."
• Only use the "A" seventh character for the very first encounter for this condition.
• Do not use if the specific narcotic or intent is known or can be reasonably inferred from the medical record.
