Personal history of allergy to narcotic agent

This code indicates a patient's past adverse reaction or hypersensitivity to a narcotic medication, such as opioids. It signifies that the patient has previously experienced an allergic response, not just a side effect, to this class of drugs.

Use this code when documenting a patient's self-reported or medically confirmed history of an allergic reaction to a narcotic agent. This is particularly relevant during pre-operative assessments, medication reconciliation, or when prescribing pain management.

• Distinguish between a true allergy (e.g., rash, anaphylaxis) and an adverse side effect (e.g., nausea, drowsiness) when selecting this code.
• This code is for a personal history of allergy; do not use it for current allergic reactions.
• Always review the patient's medical record for documentation supporting an allergic reaction to a narcotic.
