Personal history of allergy to analgesic agent

This code indicates that a patient has a documented history of an adverse reaction or hypersensitivity to a pain-relieving medication. This is a past event, meaning the patient is not currently experiencing an allergic reaction but has had one previously. It signifies a predisposition to future reactions if exposed to the same or similar agents.

Use this code when a patient's medical record explicitly states a prior allergic reaction to an analgesic, such as NSAIDs, opioids, or acetaminophen. This is particularly relevant during medication reconciliation or when prescribing new pain management therapies to ensure patient safety.

• Always verify that the allergy is to an analgesic agent, not another class of medication.
• This code is for a personal history of allergy; do not use it for current allergic reactions.
• Document the specific analgesic agent if known, as this aids in future medication management.
