Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the J31 range.
Allergic Fungal Sinusitis
Fungal infection in the PARANASAL SINUSES characterized by common allergy respiratory symptoms, recurrent NASAL POLYPS and/or ASTHMA with buildup of allergic MUCIN.
Rhinitis
Inflammation of the NASAL MUCOSA, the mucous membrane lining the NASAL CAVITIES.
Rhinitis, Allergic
An inflammation of the NASAL MUCOSA triggered by ALLERGENS.
Rhinitis, Allergic, Perennial
Inflammation of the mucous membrane of the nose similar to that found in hay fever except that symptoms persist throughout the year. The causes are usually air-borne allergens, particularly dusts, feathers, molds, animal fur, etc.
Rhinitis, Allergic, Seasonal
Allergic rhinitis that occurs at the same time every year. It is characterized by acute CONJUNCTIVITIS with lacrimation and ITCHING, and regarded as an allergic condition triggered by specific ALLERGENS.
Rhinitis, Atrophic
A chronic inflammation in which the NASAL MUCOSA gradually changes from a functional to a non-functional lining without mucociliary clearance. It is often accompanied by degradation of the bony TURBINATES, and the foul-smelling mucus which forms a greenish crust (ozena).
Rhinitis, Vasomotor
A form of non-allergic rhinitis that is characterized by nasal congestion and posterior pharyngeal drainage.
Rhinosinusitis
Obstruction of sinus drainage into the NASAL CAVITY and inflammation of the NASAL MUCOSA in the PARANASAL SINUSES.
About the J31 Code Range
```htmlICD-10 code J31 covers chronic inflammation of the nose, nasopharynx, and throat, including chronic rhinitis (J31.0), chronic nasopharyngitis (J31.1), and chronic pharyngitis (J31.2). These codes are used to classify long-lasting upper respiratory conditions that involve persistent irritation or infection.
The ICD-10 code for chronic rhinitis (J31.0) applies to ongoing inflammation of the nasal passages and includes various forms such as hypertrophic, atrophic, infectious, and non-allergic rhinitis. Common synonyms like chronic simple rhinitis, non-allergic rhinitis, and chronic hypertrophic rhinitis help medical coders identify the right code when documentation uses different terms. Chronic nasopharyngitis (J31.1) refers to persistent inflammation of the nasopharynx and shares the same name in clinical use. Chronic pharyngitis (J31.2) covers lasting inflammation of the throat with synonyms like chronic sore throat, allergic pharyngitis, and ulcer of pharynx supporting accurate coding. These codes ensure precise classification of chronic upper respiratory diseases, facilitating proper diagnosis and treatment planning.
