Mild persistent asthma
ICD-10 J45.3 is a used to indicate a diagnosis of mild persistent asthma.
Mild persistent asthma is characterized by symptoms occurring more than twice a week but less than once daily. Patients may experience nighttime symptoms more than twice a month, and their lung function is typically normal between exacerbations. The condition primarily affects the bronchial tubes, which become inflamed and narrowed, leading to difficulty in breathing. The pathophysiology involves airway hyperresponsiveness, inflammation, and obstruction, which can be triggered by allergens, respiratory infections, exercise, and environmental factors. Diagnosis is based on clinical history, physical examination, and spirometry, which measures lung function. The disease can progress if not managed properly, leading to increased frequency and severity of symptoms. Regular monitoring and management are essential to prevent exacerbations and maintain control over symptoms. Treatment often includes inhaled corticosteroids and bronchodilators, with a focus on patient education regarding trigger avoidance and self-management strategies.

J45.3 covers mild persistent asthma, which includes patients experiencing symptoms more than twice a week but less than daily, with nighttime symptoms occurring more than twice a month. It does not include patients with moderate or severe persistent asthma.
J45.3 should be used when a patient exhibits mild persistent asthma symptoms. It is important to differentiate it from J45.2 (Moderate persistent asthma) and J45.4 (Severe persistent asthma) based on the frequency and severity of symptoms.
Documentation should include a detailed history of symptoms, frequency of exacerbations, response to treatment, and any relevant spirometry results. It is crucial to note any triggers and the patient's management plan.
