Poisoning by oth opioids, accidental, sequela

This code signifies a long-term consequence or complication arising from an accidental overdose or poisoning by an opioid other than heroin, methadone, or fentanyl. It indicates that the acute poisoning event has resolved, but the patient is still experiencing residual effects directly attributable to that past incident. These sequelae can range from neurological deficits to organ damage.

Apply this code when documenting a condition that is a direct, lasting result of a previously sustained accidental poisoning by an opioid (excluding heroin, methadone, and fentanyl). This is appropriate for follow-up encounters where the acute poisoning is no longer active, but its chronic effects are being managed. Examples include persistent cognitive impairment or chronic pain syndromes stemming from the original overdose.

• Always sequence this sequela code after the code for the specific residual condition being treated.
• Ensure documentation clearly links the current condition to a past accidental opioid poisoning.
• Do not use for active poisoning or acute overdose; use the appropriate acute poisoning code for those scenarios.
