Moderate persistent asthma, uncomplicated

This code signifies a chronic respiratory condition characterized by persistent airway inflammation and obstruction, leading to daily or near-daily symptoms that are moderate in severity. Patients experience symptoms such as wheezing, shortness of breath, chest tightness, and coughing, which may impact activity and sleep, but without acute exacerbations or status asthmaticus.

Apply this code when documentation clearly indicates a diagnosis of moderate persistent asthma without any mention of an acute exacerbation or status asthmaticus. This is appropriate for ongoing management and follow-up visits where the patient's asthma is stable at a moderate persistent level. Supporting documentation should include physician notes detailing symptom frequency, severity, and the absence of acute exacerbations.

• Differentiate from mild persistent (J45.30) or severe persistent (J45.50) based on symptom frequency and severity as outlined in asthma guidelines.
• Avoid using this code if the patient is experiencing an acute exacerbation; instead, use the appropriate code for moderate persistent asthma with acute exacerbation (J45.41).
• Ensure the medical record explicitly states "uncomplicated" or lacks any mention of exacerbations to justify this specific code.
