Mild persistent asthma, uncomplicated

This code signifies a chronic respiratory condition characterized by mild, persistent inflammation and narrowing of the airways, leading to recurrent episodes of wheezing, breathlessness, chest tightness, and coughing. The "uncomplicated" designation indicates the absence of acute exacerbations or status asthmaticus at the time of encounter.

Assign this code when a patient has a documented diagnosis of mild persistent asthma without any current acute exacerbation. This is appropriate for routine follow-up visits, medication management, or when the patient's asthma is well-controlled and stable. Documentation should clearly state "mild persistent asthma" and confirm the absence of acute symptoms.

• Do not use this code if the patient is experiencing an acute exacerbation; instead, select a code from the J45.0- or J45.2- series.
• Ensure the physician's documentation explicitly states "mild persistent" to differentiate from intermittent or moderate/severe persistent asthma.
• Consider sequencing this code as a primary diagnosis when asthma management is the focus of the encounter, or as a secondary diagnosis when another condition is the primary reason for the visit.
