- Diseases of the respiratory system (J00-J99)
- J45 - AsthmaJ45.5 - Severe persistent asthma J45.50 - Severe persistent asthma, uncomplicated
In simple words: This is the most serious type of asthma.A person experiences symptoms all the time, has trouble sleeping due to asthma, and finds it difficult to do everyday things. There aren't any other problems related to their asthma at the moment.
Severe persistent asthma, uncomplicated.Characterized by continuous symptoms, frequent nighttime awakenings, and limitations in daily activities.The "uncomplicated" designation indicates the absence of further complications such as acute exacerbations or status asthmaticus.
Example 1: A patient presents with constant wheezing, shortness of breath, and limited ability to perform daily activities due to severe persistent asthma. They have frequent nighttime awakenings due to asthma symptoms but are not currently experiencing an acute exacerbation., A patient with a long history of asthma is seen for regular follow-up. They require high doses of inhaled corticosteroids and long-acting beta-agonists daily to control their symptoms.They continue to experience limitations in their activities due to shortness of breath.The patient's asthma is classified as severe persistent, uncomplicated., A patient with severe persistent asthma experiences an acute exacerbation requiring hospitalization. While hospitalized, the diagnosis would be J45.51 (Severe persistent asthma with acute exacerbation). After the exacerbation resolves and the patient is discharged, the diagnosis reverts to J45.50 (Severe persistent asthma, uncomplicated) for ongoing management.
Documentation for severe persistent asthma should include frequency and severity of symptoms (wheezing, shortness of breath, cough), lung function tests (FEV1, FVC), medication usage (including frequency of rescue inhaler use), and limitations in activity level.Frequency of nighttime awakenings due to asthma symptoms and any exacerbations or hospitalizations should also be documented.
