Unspecified asthma with status asthmaticus

This code signifies an acute, severe exacerbation of asthma, characterized by persistent and intense bronchospasm that is unresponsive to conventional bronchodilator therapy. The patient experiences severe respiratory distress, often requiring immediate medical intervention and potentially hospitalization. The "unspecified" nature indicates that the specific type of asthma (e.g., mild intermittent, moderate persistent) is not documented.

Use this code when documentation clearly states "status asthmaticus" in a patient with a diagnosis of asthma, but without further specification of the asthma's severity or type. This typically occurs in emergency department settings or during inpatient admissions for acute respiratory failure due to asthma. Supporting documentation would include physician notes detailing the patient's unremitting asthma attack and lack of response to initial treatments.

• Do not use this code if the type or severity of asthma is documented (e.g., mild intermittent, severe persistent); instead, select a more specific J45 subcategory.
• Always sequence this code as the primary diagnosis if it is the reason for the encounter or admission.
• Ensure documentation explicitly uses the term "status asthmaticus" or describes a severe, prolonged asthma attack unresponsive to treatment.
