Valid for Submission
J45.901 is a billable diagnosis code used to specify a medical diagnosis of unspecified asthma with (acute) exacerbation. The code J45.901 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code J45.901 might also be used to specify conditions or terms like acute asthma, acute exacerbation of allergic asthma, acute exacerbation of asthma, acute exacerbation of asthma co-occurrent with allergic rhinitis, acute exacerbation of intrinsic asthma , acute severe exacerbation of allergic asthma, etc.
The code is commonly used in pediatrics medical specialties to specify clinical concepts such as asthma.
Unspecified diagnosis codes like J45.901 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen. That makes them very sensitive, and they may react strongly to things that you are allergic to or find irritating. When your airways react, they get narrower and your lungs get less air.
Symptoms of asthma include
- Coughing, especially early in the morning or at night
- Chest tightness
- Shortness of breath
Not all people who have asthma have these symptoms. Having these symptoms doesn't always mean that you have asthma. Your doctor will diagnose asthma based on lung function tests, your medical history, and a physical exam. You may also have allergy tests.
When your asthma symptoms become worse than usual, it's called an asthma attack. Severe asthma attacks may require emergency care, and they can be fatal.
Asthma is treated with two kinds of medicines: quick-relief medicines to stop asthma symptoms and long-term control medicines to prevent symptoms.
