The ICD-10 code range for Influenza and pneumonia J09-J18 is medical classification list by the World Health Organization (WHO).
Influenza due to identified novel influenza A virus ICD-10-CM J09. X2 is grouped within Diagnostic Related Group(s) (MS-DRG v39.0):
Influenza is a common cause of pneumonia, especially among younger children, the elderly, pregnant women, or those with certain chronic health conditions or who live in a nursing home. Most cases of flu never lead to pneumonia, but those that do tend to be more severe and deadly.
Influenza virus infection alone can cause severe pneumonia and ARDS, but it can also act in conjunction with a bacterial infection (discussed below). It can precede a pneumonia episode caused by a secondary bacterial infection, most commonly by S. aureus and S.
ICD-10 code J18. 9 for Pneumonia, unspecified organism is a medical classification as listed by WHO under the range - Diseases of the respiratory system .
Many of the ICD-10-CM diagnosis codes include the manifestation — for example, J09. X2 – Influenza due to identified novel influenza A virus with other respiratory manifestations.
The flu is a contagious respiratory illness caused by viruses. It is different from a cold. It usually comes on suddenly. Pneumonia is an infection of the lungs that can cause mild to severe illness in people of all ages.
The flu usually comes on suddenly, while pneumonia takes longer to develop and can be a complication from the flu. The flu is caused by a viral infection, while pneumonia can be caused by either a bacterial infection or viral infection. Flu symptoms include: Body aches and pains.
Flu symptoms may be bad, but they usually get better within a few days. A cold can last up to 10 days. But pneumonia symptoms can stick around up to a month or longer. And bronchitis can last several months in some cases.
Epidemiology of secondary bacterial pneumonia Primary influenza virus infection may lead to lower respiratory tract symptoms, but secondary bacterial infections during and shortly after recovery from influenza virus infection are a much more common cause of pneumonia.
The flu can weaken the immune system and trigger an inflammatory response in your body. This makes you more susceptible to getting other infections. Pneumonia may be a complication of the flu virus.
In adults, you can administer a pneumococcal vaccine (PCV15, PCV20, or PPSV23) during the same visit with influenza vaccination. Administer each vaccine with a separate syringe and, if feasible, at a different injection site. Annual influenza vaccination is important to help prevent the flu.
