Severe persistent asthma, uncomplicated

This code signifies a chronic respiratory condition characterized by severe, ongoing airway inflammation and obstruction that is not complicated by acute exacerbations or status asthmaticus. Patients experience frequent and intense asthma symptoms, significantly impacting daily activities and requiring high-dose controller medications.

Apply this code when documentation clearly indicates a diagnosis of severe persistent asthma without any mention of an acute exacerbation or status asthmaticus. This typically involves patients whose asthma is poorly controlled despite optimal therapy, exhibiting symptoms such as daily wheezing, coughing, and shortness of breath, and frequent nocturnal awakenings.

• Ensure documentation explicitly states "severe persistent asthma" and "uncomplicated" or absence of acute exacerbation.
• Do not use if an acute exacerbation is present; instead, use a more specific code from the J45.5 series.
• Consider sequencing with codes for associated conditions, such as chronic obstructive pulmonary disease (COPD) if applicable.
