Other asthma
ICD-10 J45.99 is a used to indicate a diagnosis of other asthma.
J45.99 refers to 'Other asthma,' which encompasses various forms of asthma that do not fit into the more specific categories defined in the ICD-10 coding system. Asthma is a chronic inflammatory disease of the airways characterized by recurrent breathing problems, wheezing, chest tightness, and coughing. The condition results from a complex interaction of genetic and environmental factors affecting the bronchial tubes, leading to airway hyperresponsiveness, inflammation, and obstruction. Disease progression can vary significantly among individuals, with some experiencing intermittent symptoms while others may have persistent and severe manifestations. Diagnostic considerations include a thorough clinical history, physical examination, and pulmonary function tests, such as spirometry, to assess airway obstruction and responsiveness to bronchodilators. J45.99 is particularly relevant for patients whose asthma does not fall under the more common classifications, such as allergic asthma or exercise-induced asthma, and may include atypical presentations or those with mixed features. Accurate coding is essential for appropriate treatment planning and management of asthma, which may involve inhaled corticosteroids, bronchodilators, and lifestyle modifications to minimize triggers.

J45.99 covers various forms of asthma that do not fit into the more specific categories, including atypical asthma presentations, mixed asthma types, and cases where the specific etiology is not identified.
J45.99 should be used when the asthma type is not clearly defined by other codes, particularly when the patient exhibits symptoms that do not align with more specific asthma classifications.
Documentation should include a detailed patient history, symptom descriptions, results from pulmonary function tests, and any previous treatments or responses to therapy to substantiate the diagnosis of 'Other asthma.'
