Allergy to Penicillin ICD-10-CM Codes

Symptoms can include hives, rash, itching, swelling, shortness of breath, wheezing, and anaphylaxis. Some patients may also experience delayed reactions like fever, joint pain, or severe skin rashes.

Diagnosis is based on a detailed clinical history and may be confirmed through skin testing or, in some cases, graded drug challenges under medical supervision.

Treatment involves avoiding penicillin and related antibiotics, using alternative medications, and prescribing epinephrine for severe allergies; allergy evaluation and desensitization may be considered if penicillin use is essential.
