Personal history of allergy to penicillin

This code indicates a patient's past adverse reaction to penicillin, even if the reaction was mild or occurred many years ago. It signifies that the patient has a documented history of an allergic response to this specific antibiotic.

This code is used when a patient's medical record explicitly states a prior allergy to penicillin. It is crucial for documenting patient safety concerns and guiding future medication prescriptions.

• Always verify the allergy is specifically to penicillin, not a broader class of antibiotics.
• This code is for a personal history of allergy, not an active allergic reaction.
• Do not use if the patient only reports a side effect (e.g., nausea) rather than a true allergic response.
