Version 2021

Valid for Submission

J15.9 is a billable diagnosis code used to specify a medical diagnosis of unspecified bacterial pneumonia. The code J15.9 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 J15.9 might also be used to specify conditions or terms like bacterial pneumonia, bacterial pneumonia associated with aids, bacterial pneumonia co-occurrent with human immunodeficiency virus infection, bronchopneumonia due to bacteria, disorder of respiratory system co-occurrent with human immunodeficiency virus infection , healthcare associated bacterial pneumonia, etc.

Unspecified diagnosis codes like J15.9 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


Pneumonia

Also called: Bronchopneumonia

Pneumonia is an infection in one or both of the lungs. Many germs, such as bacteria, viruses, and fungi, can cause pneumonia. You can also get pneumonia by inhaling a liquid or chemical. People most at risk are older than 65 or younger than 2 years of age, or already have health problems.

Symptoms of pneumonia vary from mild to severe. See your doctor promptly if you

Your doctor will use your medical history, a physical exam, and lab tests to diagnose pneumonia. Treatment depends on what kind you have. If bacteria are the cause, antibiotics should help. If you have viral pneumonia, your doctor may prescribe an antiviral medicine to treat it.

Preventing pneumonia is always better than treating it. Vaccines are available to prevent pneumococcal pneumonia and the flu. Other preventive measures include washing your hands frequently and not smoking.
