Personal history of allergy to other specified medicinal agents

This code indicates a patient's past adverse reaction to a specific medication, excluding antibiotics, sulfonamides, and other commonly categorized agents. It signifies that while the patient is not currently experiencing an allergic reaction, they have a documented history of one to a drug not otherwise specified in more granular allergy codes.

Apply this code when a patient's medical record clearly states a previous allergic response to a medication that doesn't fall under more specific ICD-9-CM allergy categories (e.g., opioids, NSAIDs, specific chemotherapy agents). This is often used for drugs like muscle relaxants, anti-emetics, or certain cardiovascular medications.

• Always review the patient's medication history and allergy list thoroughly.
• Ensure the documented allergy is to a medicinal agent and not a food, environmental factor, or other substance.
• If a more specific ICD-9-CM code exists for the particular drug class, use that instead.
