Subacute cough
ICD-10 R05.2 is a billable code used to indicate a diagnosis of subacute cough.
Subacute cough is defined as a cough that persists for more than three weeks but less than eight weeks. It often follows an acute respiratory infection and may be associated with residual airway inflammation or other underlying conditions. Patients may experience a dry or productive cough, which can be exacerbated by environmental factors such as allergens or irritants. Common causes include post-infectious cough, asthma, gastroesophageal reflux disease (GERD), and chronic bronchitis. The cough may be accompanied by other symptoms such as wheezing, shortness of breath, or chest discomfort. Clinical evaluation typically involves a thorough history and physical examination, and may include diagnostic tests such as chest X-rays, spirometry, or allergy testing to identify underlying causes. Management focuses on treating the underlying condition and may involve bronchodilators, corticosteroids, or lifestyle modifications.
Detailed history of cough duration, associated symptoms, and any previous treatments.
Patients presenting with a persistent cough following a respiratory infection, with or without wheezing.
Consideration of comorbidities such as asthma or COPD that may complicate the clinical picture.
Acute care documentation must include a thorough assessment of respiratory status and any immediate interventions.
Patients presenting with acute exacerbation of cough, possibly with respiratory distress.
Rapid assessment and documentation of vital signs and oxygen saturation are critical.
Used to assess lung function in patients with persistent cough.
Document the indication for the test and the results.
Internal medicine may use spirometry more frequently than emergency medicine.
Acute cough lasts less than three weeks, subacute cough lasts between three and eight weeks, and chronic cough persists for more than eight weeks. Accurate coding requires documentation of the duration.
