Poisn by analeptics and opioid receptor antag, slf-hrm, init

This code signifies a patient presenting with an adverse effect from analeptics (stimulants) or opioid receptor antagonists, resulting from a deliberate act of self-harm. The patient is in the acute phase of treatment for this poisoning.

Apply this code when documenting an initial encounter for a patient who has intentionally overdosed on or misused analeptics (e.g., caffeine, methylphenidate) or opioid antagonists (e.g., naloxone, naltrexone) with suicidal intent. This includes situations where the patient is receiving initial emergency care, stabilization, or diagnostic workup for the poisoning.

• Always use an external cause code (e.g., X60-X69) in conjunction with this code to specify the intent and circumstances.
• This "A" seventh character indicates the initial encounter for active treatment of the poisoning.
• Differentiate intentional self-harm from accidental poisoning (T50.7X1-) or assault (T50.7X3-).
