Upper respiratory tract hypersensitivity reaction, site unspecified
ICD-10 J39.3 is a billable code used to indicate a diagnosis of upper respiratory tract hypersensitivity reaction, site unspecified.
Upper respiratory tract hypersensitivity reaction, site unspecified, refers to an exaggerated immune response occurring in the upper respiratory tract, which can manifest as allergic rhinitis, nasal congestion, sneezing, and other respiratory symptoms. This condition may arise from exposure to allergens such as pollen, dust mites, mold, or pet dander. The anatomy involved primarily includes the nasal passages, sinuses, and throat. Disease progression can vary; acute hypersensitivity reactions may resolve quickly with allergen avoidance or treatment, while chronic exposure can lead to persistent symptoms and complications such as sinusitis or asthma. Diagnostic considerations include a thorough patient history, physical examination, and possibly allergy testing to identify specific triggers. Clinicians should differentiate hypersensitivity reactions from other respiratory conditions, such as infections or structural abnormalities, to ensure appropriate management.

J39.3 covers hypersensitivity reactions in the upper respiratory tract, including allergic rhinitis and other non-specific allergic responses that do not have a clearly defined site of reaction.
J39.3 should be used when the hypersensitivity reaction is not specifically classified under other codes, particularly when the site of the reaction is unspecified or when multiple allergens are involved.
Documentation should include a detailed patient history of symptoms, potential allergens, results from allergy testing, and any previous treatments or responses to therapy.
