Cracking The Code: Understanding Exercise-Induced Asthma ICD-10

What is Exercise Induced Asthma ICD-10?

Exercise-induced asthma, also known as exercise-induced bronchoconstriction, is a condition in which physical activity triggers asthma symptoms such as coughing, wheezing, chest tightness, and shortness of breath. It is a common condition among athletes and individuals who engage in physical activities.

ICD–CM Diagnosis Code J

Exercise-induced asthma falls under the MS-DRG 202 Respiratory System Diagnosis with Ventilator Support. This DRG is used to group patients with respiratory system diagnoses that require ventilator support.

Convert to ICD-9 Code

In the ICD-9 coding system, exercise-induced asthma is classified under the code 493.82. This code is used to identify and classify asthma conditions triggered by physical activity.

Code History

The ICD-10 code for exercise-induced asthma was introduced in October 2015 as part of the transition from ICD-9 to ICD-10 coding systems. This change aimed to improve accuracy and specificity in coding respiratory conditions.

Approximate Synonyms

Exercise-induced bronchoconstriction
Exercise-induced respiratory symptoms
Exercise-induced wheezing

Clinical Information

Exercise-induced asthma is characterized by the narrowing of the airways in response to physical exertion. This constriction leads to asthma symptoms that can vary in severity depending on the individual and the level of physical activity.


The exact cause of exercise-induced asthma is not fully understood, but it is believed to be triggered by the combination of physical activity and environmental factors such as cold air, pollution, or allergens. These factors can irritate the airways and lead to bronchoconstriction.


Common symptoms of exercise-induced asthma include coughing, wheezing, chest tightness, and shortness of breath during or after physical activity. These symptoms can range from mild to severe and may interfere with an individual’s ability to exercise comfortably.


Diagnosing exercise-induced asthma may involve a physical examination, medical history review, lung function tests such as spirometry, and exercise challenge tests. These tests help healthcare providers evaluate airway responsiveness and confirm the diagnosis.


Treatment for exercise-induced asthma typically involves using a combination of medications such as short-acting beta-agonists (SABAs), inhaled corticosteroids, and leukotriene modifiers. In addition, avoiding triggers, warming up before exercise, and using a pre-exercise bronchodilator can help manage symptoms.


Exercise-induced asthma is a common condition that can impact individuals who engage in physical activities. By understanding the causes, symptoms, diagnosis, and treatment options for this condition, individuals can effectively manage their asthma symptoms and continue to enjoy an active lifestyle.
