2025 ICD-10-CM code A02.21

Salmonella meningitis. This occurs when Salmonella bacteria spread to the meninges (membranes surrounding the brain and spinal cord).

Use additional code to identify resistance to antimicrobial drugs (Z16.-).

Medical necessity for treatment of Salmonella meningitis is established by the presence of clinical symptoms and positive laboratory findings confirming the infection.Hospitalization and intravenous antibiotics are typically required.

Clinicians are responsible for diagnosing and managing salmonella meningitis, which involves hospitalization, administering antibiotics, and providing supportive care such as rehydration. Prevention may include vaccination for travelers to areas with poor sanitation.

In simple words: Salmonella meningitis is a serious infection of the lining of the brain and spinal cord. It's caused by the same bacteria that cause food poisoning from Salmonella. It can cause severe headaches, high fever, and stiff neck. It needs to be treated in the hospital with antibiotics.

Salmonella meningitis is an infection of the meninges, the protective membranes that cover the brain and spinal cord, caused by Salmonella bacteria. It is a complication of Salmonella infection, typically acquired through contaminated food. Symptoms include severe headache, high fever, meningeal irritation, and in severe cases, seizures, hydrocephalus, subdural empyema, mental retardation, or even death. Diagnosis involves culturing blood and cerebrospinal fluid. Treatment requires hospitalization, rehydration, antibiotics, and other supportive care.

Example 1: A patient presents with a high fever, stiff neck, and severe headache after consuming contaminated food. Laboratory tests confirm Salmonella in their cerebrospinal fluid, indicating salmonella meningitis., An infant develops a fever, irritability, and poor feeding.Testing reveals Salmonella infection, and subsequent lumbar puncture confirms Salmonella meningitis., An individual with a compromised immune system develops Salmonella sepsis after eating undercooked chicken. The infection spreads to the central nervous system, resulting in Salmonella meningitis.

Documentation should include signs and symptoms (e.g., fever, headache, stiff neck), laboratory results confirming Salmonella infection (blood and cerebrospinal fluid cultures), imaging studies (if performed), and treatment details.
