What This Code Means

Asthma that occurs occasionally with mild symptoms, but the patient is currently in severe respiratory distress with continuous symptoms and poor response to treatment.

Coding Tips

• •Status asthmaticus is a life-threatening condition requiring intensive management; ensure documentation clearly indicates this severe state
• •This is more severe than simple exacerbation; look for terms like 'severe exacerbation,' 'status asthmaticus,' or 'acute severe asthma'

Clinical Significance

Mild intermittent asthma with status asthmaticus represents a severe, life-threatening asthma attack in a patient whose baseline disease is classified as mild intermittent. Status asthmaticus is a medical emergency characterized by severe bronchospasm that does not respond to standard bronchodilator therapy, requiring intensive treatment and often mechanical ventilation.

Documentation Requirements

• ✓Provider documentation of status asthmaticus — this is a specific clinical term indicating treatment-refractory severe bronchospasm
• ✓Baseline asthma severity classified as mild intermittent
• ✓Clinical evidence of severe attack: severe respiratory distress, inability to speak in full sentences, accessory muscle use
• ✓Documentation of treatment failure: multiple nebulizer treatments, IV corticosteroids, epinephrine
• ✓Vital signs and oxygen saturation demonstrating severity
• ✓ICU admission and/or mechanical ventilation if applicable
