Poisoning by fentanyl or fentanyl analogs, self-harm, init

This code signifies a patient presenting with an adverse physiological reaction due to the deliberate ingestion, injection, or exposure to fentanyl or its analogs, with the intent to harm oneself. The patient is in the initial phase of treatment for this poisoning event.

Apply this code when documentation clearly indicates a patient has intentionally self-poisoned with fentanyl or a fentanyl analog. This is appropriate for the first encounter for treatment of the acute effects of the poisoning.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires clear documentation of "intentional self-harm" and "initial encounter."
• Do not use for accidental exposures or adverse effects of properly administered medication.
