Not Valid for Submission
J45.90 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of unspecified 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.
Unspecified diagnosis codes like J45.90 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.
Specific Coding for Unspecified asthma
Non-specific codes like J45.90 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 unspecified 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 J45.90:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Asthmatic bronchitis NOS
- Childhood asthma NOS
- Late onset asthma
- 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.
