Not Valid for Submission
J45 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of asthma. The code is not specific and is NOT valid for the year 2021 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
Specific Coding for Asthma
Non-specific codes like J45 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for asthma:
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code J45:
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- allergic (predominantly) asthma
- allergic bronchitis NOS
- allergic rhinitis with asthma
- atopic asthma
- extrinsic allergic asthma
- hay fever with asthma
- idiosyncratic asthma
- intrinsic nonallergic asthma
- nonallergic asthma
Use Additional CodeUse Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to identify:
- eosinophilic asthma J82.83
- exposure to environmental tobacco smoke Z77.22
- exposure to tobacco smoke in the perinatal period P96.81
- history of tobacco dependence Z87.891
- occupational exposure to environmental tobacco smoke Z57.31
- tobacco dependence F17
- tobacco use Z72.0
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- detergent asthma J69.8
- eosinophilic asthma J82
- miner's asthma J60
- wheezing NOS R06.2
- wood asthma J67.8
Type 2 ExcludesType 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- ASTHMA CHRONIC OBSTRUCTIVE PULMONARY DISEASE OVERLAP SYNDROME-. syndrome with clinical features of both asthma and copd.
- ASTHMA-. a form of bronchial disorder with three distinct components: airway hyper responsiveness respiratory hypersensitivity airway inflammation and intermittent airway obstruction. it is characterized by spasmodic contraction of airway smooth muscle wheezing and dyspnea dyspnea paroxysmal.
- ASTHMA EXERCISE INDUCED-. asthma attacks following a period of exercise. usually the induced attack is short lived and regresses spontaneously. the magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely warm humid air blunts or abolishes it.
- DYSPNEA PAROXYSMAL-. a disorder characterized by sudden attacks of respiratory distress in at rest patients with heart failure and pulmonary edema. it usually occurs at night after several hours of sleep in a reclining position. patients awaken with a feeling of suffocation coughing a cold sweat and tachycardia. when there is significant wheezing it is called cardiac asthma.
- STATUS ASTHMATICUS-. a sudden intense and continuous aggravation of a state of asthma marked by dyspnea to the point of exhaustion and collapse and not responding to the usual therapeutic efforts.
- TYLOPHORA-. a plant genus of the family asclepiadaceae. members contain phenanthro indolizidine alkaloids.
- CONYZA-. a plant genus of the family asteraceae. members contain alkenynes daucosterol friedelinol conyzasaponins and other triterpenes.
- ASTHMA ASPIRIN INDUCED-. asthmatic adverse reaction e.g. bronchoconstriction to conventional nsaids including aspirin use.
- AIRWAY REMODELING-. the structural changes in the number mass size and/or composition of the airway tissues.
- ASTHMA OCCUPATIONAL-. asthma attacks caused triggered or exacerbated by occupational exposure.
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.

Allergic asthma Asthma is a breathing disorder characterized by inflammation of the airways and recurrent episodes of breathing difficulty. These episodes, sometimes referred to as asthma attacks, are triggered by irritation of the inflamed airways. In allergic asthma, the attacks occur when substances known as allergens are inhaled, causing an allergic reaction. Allergens are harmless substances that the body's immune system mistakenly reacts to as though they are harmful. Common allergens include pollen, dust, animal dander, and mold. The immune response leads to the symptoms of asthma. Allergic asthma is the most common form of the disorder.A hallmark of asthma is bronchial hyperresponsiveness, which means the airways are especially sensitive to irritants and respond excessively. Because of this hyperresponsiveness, attacks can be triggered by irritants other than allergens, such as physical activity, respiratory infections, or exposure to tobacco smoke, in people with allergic asthma.An asthma attack is characterized by tightening of the muscles around the airways (bronchoconstriction), which narrows the airway and makes breathing difficult. Additionally, the immune reaction can lead to swelling of the airways and overproduction of mucus. During an attack, an affected individual can experience chest tightness, wheezing, shortness of breath, and coughing. Over time, the muscles around the airways can become enlarged (hypertrophied), further narrowing the airways.Some people with allergic asthma have another allergic disorder, such as hay fever (allergic rhinitis) or food allergies. Asthma is sometimes part of a series of allergic disorders, referred to as the atopic march. Development of these conditions typically follows a pattern, beginning with eczema (atopic dermatitis), followed by food allergies, then hay fever, and finally asthma. However, not all individuals with asthma have progressed through the atopic march, and not all individuals with one allergic disease will develop others.
