Asthma Exacerbation

Usage Guidelines & Examples

• Use J45.41 for mild persistent asthma exacerbation and J45.52 for severe persistent asthma exacerbation.
• Do not use these codes for chronic obstructive pulmonary disease (COPD) exacerbations or other respiratory conditions.
• Compare with J45.909 (Unspecified asthma) and J45.20 (Mild intermittent asthma) for appropriate coding.
• Common errors include misclassifying the severity of the exacerbation; ensure documentation supports the chosen code.
• In complex cases, consider the patient's history and response to treatment when selecting the appropriate code.
