ICD-10 Code J30.81 – Allergic rhinitis due to animal (cat) (dog) hair and dander (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J30.81 – Allergic rhinitis due to animal (cat) (dog) hair and dander
What it is
J30.81 identifies allergic rhinitis triggered by exposure to animal hair or dander, commonly from cats or dogs. Use it when the record documents an allergic nasal reaction linked to these animal allergens.
Clinical signs
Typical findings include sneezing, runny or itchy nose, nasal congestion, and watery eyes after animal exposure. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents allergic rhinitis due to cat or dog hair or dander, or a similar animal allergen. It fits outpatient, emergency, or specialty notes that clearly connect symptoms to animal exposure. If the allergen is not specified, check documentation.
Do not use for
Do not use J30.81 for nonallergic rhinitis, asthma alone, or general environmental allergies without animal trigger documentation. Do not assume the cause is pet-related unless the record states it.
Coding tip
Confirm the animal trigger and rhinitis diagnosis are both documented before assigning J30.81.
