ICD-Code J20.9 is a billable ICD-10 code used for healthcare diagnosis reimbursement of Acute Bronchitis, Unspecified. Its corresponding ICD-9 code is 466.0 Billable: Yes ICD-9 Code Transition: 466.0 Code J20.9 is the diagnosis code used for Acute Bronchitis, Unspecified. Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to your lungs. Acute bronchitis is more severe and can become chronic and progress to pneumonia. Other Synonyms Include: ICD (International Statistical Classification of Diseases and Related Health problems) is now on its 10th revision. ICD-10 codes are the byproduct of that revision. This medical classification list is generated by the World Health Organization (WHO), and is used to help healthcare providers identify and code health conditions. ICD-10 is required for use by physicians and healthcare providers under the Health Insurance Portability & Accountability Act (HIPAA) and will replace all ICD-9 code sets. Many more new diagnoses can be tracked using ICD-10 than with ICD-9. Some expanded code sets, like ICD-10-CM, have over 70,000 codes.

- Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to your lungs. It causes a cough that often brings up mucus, as well as shortness of breath, wheezing, and chest tightness. There are two main types of bronchitis: acute and chronic. The same viruses that cause colds and the flu often cause acute bronchitis. These viruses spread through the air when people cough, or through physical contact (for example, on unwashed hands). Being exposed to tobacco smoke, air pollution, dusts, vapors, and fumes can also cause acute bronchitis. Bacteria can also cause acute bronchitis, but not as often as viruses.most cases of acute bronchitis get better within several days. But your cough can last for several weeks after the infection is gone. If you think you have acute bronchitis, see your healthcare provider.treatments include rest, fluids, and aspirin (for adults) or acetaminophen to treat fever. A humidifier or steam can also help. You may need inhaled medicine to open your airways if you are wheezing. You probably do not need antibiotics. They don't work against viruses - the most common cause of acute bronchitis. If your healthcare provider thinks you have a bacterial infection, he or she may prescribe antibiotics.
- Sudden inflammation of the tracheobronchial tree, which comprises the trachea, or windpipe, and the bronchi; typically associated with a viral upper respiratory tract infection, such as the common cold, and is usually mild; in patients with chronic lung or heart disease, acute bronchitis is more severe, and can become chronic and progress to pneumonia.
