A39.4 is a billable diagnosis code used to specify a medical diagnosis of meningococcemia, unspecified. The code A39.4 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code A39.4 might also be used to specify conditions or terms like meningococcemia or septic shock co-occurrent with acute organ dysfunction due to meningococcus.
Unspecified diagnosis codes like A39.4 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.

|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|870||SEPTICEMIA OR SEVERE SEPSIS WITH MV >96 HOURS||18||6.4248|
|871||SEPTICEMIA OR SEVERE SEPSIS WITHOUT MV >96 HOURS WITH MCC||18||1.8682|
|872||SEPTICEMIA OR SEVERE SEPSIS WITHOUT MV >96 HOURS WITHOUT MCC||18||1.0216|

Information for Patients
Meningococci are a type of bacteria that cause serious infections. The most common infection is meningitis, which is an inflammation of the thin tissue that surrounds the brain and spinal cord. Meningococci can also cause other problems, including a serious bloodstream infection called sepsis.
Meningococcal infections can spread from person to person. Risk factors include
- Age - it is more common in infants, teens, and young adults
- Living in close quarters, such as in college dorms or military settings
- Certain medical conditions, such as not having a spleen
- Travel to areas where meningococcal disease is common
In its early stages, you may have flu-like symptoms and a stiff neck. But the disease can progress quickly and can be fatal. Early diagnosis and treatment are extremely important. Lab tests on your blood and cerebrospinal fluid can tell if you have it. Treatment is with antibiotics. Since the infection spreads from person to person, family members may also need to be treated.
A vaccine can prevent meningococcal infections.
