Understanding Exercise-Induced Asthma: ICD-10 Codes And Management Strategies

What is Exercise-Induced Asthma ICD-10?

Exercise-induced asthma, also known as exercise-induced bronchoconstriction, is a condition that causes narrowing of the airways in the lungs during or after physical exercise. This can result in symptoms such as wheezing, coughing, shortness of breath, and chest tightness. In the International Classification of Diseases, Tenth Revision (ICD-10), exercise-induced asthma is classified under code J45.31.

Code Information

The ICD-10 code for exercise-induced asthma is J45.31. This code is used to identify and classify the condition for billing and administrative purposes. It is important to use the correct code when documenting and treating patients with exercise-induced asthma to ensure accurate diagnosis and treatment.

Diagnostic Related Groups (MS-DRG)

Exercise-induced asthma falls under the diagnosis-related group (DRG) 202 – Bronchitis and Asthma with CC/MCC. This DRG is used for grouping patients with similar diagnoses for the purpose of reimbursement under the Medicare Severity-Diagnosis Related Group (MS-DRG) system.

Convert to ICD-9 Code

In the Ninth Revision of the International Classification of Diseases (ICD-9), exercise-induced asthma is classified under code 493.82. This code is used for the same purpose as the ICD-10 code to identify and classify the condition for billing and administrative purposes.

Code History

The ICD-10 code for exercise-induced asthma, J45.31, was introduced in 2016 as part of the update from ICD-9 to ICD-10. This change was made to improve the specificity and accuracy of coding for various medical conditions, including exercise-induced asthma.

Approximate Synonyms

Exercise-induced asthma is also known by other names, such as exercise-induced bronchoconstriction or exercise-induced airway hyperresponsiveness. These terms are used interchangeably to describe the condition in which physical activity triggers asthma symptoms.

Clinical Information

Exercise-induced asthma is a common condition that affects both children and adults who have asthma. It is triggered by physical activity and can vary in severity depending on the individual. Symptoms typically occur during or shortly after exercise and may last for a few minutes to several hours.


The exact cause of exercise-induced asthma is not fully understood, but it is believed to be related to the combination of physical activity and environmental factors. When a person with asthma exercises, they breathe in more air, which can lead to the cooling and drying of the airways, triggering the asthma symptoms.


Common symptoms of exercise-induced asthma include wheezing, coughing, shortness of breath, chest tightness, and decreased exercise tolerance. These symptoms can vary in intensity and may be more severe in cold, dry air or during high-intensity exercise.


Exercise-induced asthma is typically diagnosed based on a patient’s medical history, symptoms, and physical examination. In some cases, additional tests such as spirometry or exercise challenge tests may be performed to confirm the diagnosis and assess the severity of the condition.


Treatment for exercise-induced asthma may include medications such as short-acting beta-agonists (SABAs) to provide quick relief of symptoms before exercise, or long-acting medications such as inhaled corticosteroids to help control inflammation in the airways. In addition, avoiding triggers, warming up before exercise, and using a scarf or mask to cover the mouth and nose in cold weather can help prevent symptoms.


Exercise-induced asthma is a common condition that can significantly impact an individual’s ability to participate in physical activities. By understanding the causes, symptoms, diagnosis, and treatment options for exercise-induced asthma, healthcare providers can effectively manage the condition and improve the quality of life for patients.


1. Can exercise-induced asthma be prevented?

Exercise-induced asthma can be managed and prevented by taking appropriate medications, avoiding triggers, and warming up before physical activity.

2. Is exercise-induced asthma the same as regular asthma?

Exercise-induced asthma is a specific type of asthma that is triggered by physical activity. It is important to differentiate between the two conditions for proper diagnosis and treatment.

3. Can children have exercise-induced
