0.000What This Code Means
Asthma of unspecified severity with status asthmaticus, a severe, life-threatening asthma attack unresponsive to standard treatment.
Coding Tips
- •Use this code only when the severity of asthma cannot be determined from documentation
- •Status asthmaticus is a medical emergency; prioritize obtaining complete documentation of asthma severity when possible
Clinical Significance
Unspecified asthma with status asthmaticus represents a life-threatening, treatment-refractory asthma attack in a patient whose baseline severity has not been classified. While the acute event is captured, the unspecified baseline severity limits the code's risk adjustment value and suggests a documentation improvement opportunity.
Documentation Requirements
- ✓Provider documentation of status asthmaticus
- ✓Documentation that the patient has asthma (severity unspecified)
- ✓Evidence of treatment-refractory bronchospasm
- ✓ICU-level care documentation
- ✓Respiratory monitoring and interventions
- ✓Post-stabilization plan including severity classification
