Allergy status to penicillin

This code indicates a patient's documented history of an allergic reaction to penicillin, regardless of the severity or type of reaction. It signifies a known adverse response to this specific antibiotic class.

Apply this code when a patient's medical record clearly states a penicillin allergy. This is crucial for medication reconciliation and to prevent prescribing penicillin or related antibiotics. It should be used even if the patient is not currently experiencing an allergic reaction.

• Always verify documented allergy status in the patient's chart.
• Do not use this code for adverse effects that are not true allergic reactions (e.g., nausea, diarrhea without other allergic symptoms).
• This code is for historical allergy status, not for an active allergic reaction (which would be coded separately).
