Severe persistent asthma with status asthmaticus

This code signifies a chronic respiratory condition characterized by severe, ongoing airway inflammation and obstruction that does not respond readily to conventional bronchodilator therapy. It specifically indicates that the patient is experiencing status asthmaticus, a life-threatening exacerbation of asthma involving severe, unremitting bronchospasm.

Apply this code when documentation clearly indicates a diagnosis of severe persistent asthma and the patient is currently experiencing status asthmaticus, requiring urgent medical intervention. Supporting documentation should detail the severity of the asthma, its persistent nature, and the acute, severe exacerbation consistent with status asthmaticus.

• Ensure documentation explicitly states "status asthmaticus" in addition to severe persistent asthma.
• Do not use this code for acute exacerbations of asthma that do not meet the criteria for status asthmaticus.
• Consider sequencing with codes for respiratory failure if present, as status asthmaticus often leads to such complications.
