2025 ICD-10-CM code A83.1
Western equine encephalitis.
Medical necessity for treatment is established by the confirmed diagnosis of WEE and the presence of neurological symptoms requiring medical intervention.
Diagnosis of WEE is based on patient history, physical and neurological examination, and laboratory tests like cerebrospinal fluid analysis. Treatment focuses on managing symptoms, such as reducing brain swelling and controlling seizures. Prevention involves avoiding mosquito bites.
- Certain infectious and parasitic diseases (A00-B99)
- Viral and prion infections of the central nervous system (A80-A89)
In simple words: Western equine encephalitis (WEE) is a disease spread by mosquitoes that can cause swelling in the brain. It can feel like the flu at first, but sometimes it becomes more serious, causing confusion, seizures, or even coma.
Western equine encephalitis (WEE) is a mosquito-borne viral infection that causes inflammation of the brain. Symptoms can range from mild flu-like illness to severe neurological problems like encephalitis, seizures, and coma.It's transmitted through the bite of an infected mosquito, which primarily feeds on infected birds.
Example 1: A patient presents with fever, headache, and muscle aches after a camping trip.The symptoms progress to stiff neck, confusion, and seizures.CSF analysis confirms WEE., An infant develops high fever, irritability, and poor feeding.Further examination reveals signs of encephalitis. WEE is diagnosed through laboratory testing., An elderly individual experiences mild flu-like symptoms which are initially dismissed. However, they later develop neurological symptoms prompting further investigation, leading to a diagnosis of WEE.
Documentation should include signs and symptoms, exposure to mosquitoes, lab results (especially CSF analysis), and imaging findings (CT, MRI, EEG).
