Poisoning by oth opioids, intentional self-harm, init encntr

This diagnosis code signifies a patient presenting with adverse effects from an overdose or misuse of an opioid substance, excluding heroin, methadone, and other specified opioids. The key characteristic is that the patient deliberately inflicted this harm upon themselves, and this is the very first time they are being treated for this specific poisoning event.

This code is appropriate for emergency department visits or initial inpatient admissions where a patient has intentionally ingested or administered an opioid (other than those with more specific codes) with suicidal intent. It applies to the initial phase of treatment and evaluation for such an event.

• Ensure documentation clearly states the intent as self-harm or suicidal.
• Verify the specific opioid involved to rule out more precise codes (e.g., T40.1X2A for heroin).
• Confirm this is the initial encounter for this specific poisoning; subsequent care would use a different seventh character.
