ICD10 code of Acute Disseminated Encephalomyelitis and ICD9 code
What is the ICD10 code for Acute Disseminated Encephalomyelitis? And the ICD9 code for Acute Disseminated Encephalomyelitis?
Acute Disseminated Encephalomyelitis (ADEM) is primarily classified under the ICD-10 code G04.0 (Postinfectious encephalitis and encephalomyelitis). In the older ICD-9 clinical modification system, Acute Disseminated Encephalomyelitis was identified by the code 323.5.
What is the clinical nature of Acute Disseminated Encephalomyelitis?
Acute Disseminated Encephalomyelitis is a rare, immune-mediated demyelinating disorder of the central nervous system. It typically occurs following a viral or bacterial infection, though it can occasionally follow vaccinations. Unlike multiple sclerosis, Acute Disseminated Encephalomyelitis usually presents as a monophasic illness, meaning it occurs as a single episode of inflammation in the brain and spinal cord.
How is Acute Disseminated Encephalomyelitis identified?
Diagnosis of Acute Disseminated Encephalomyelitis is primarily clinical, supported by neuroimaging and the exclusion of other neurological conditions. Physicians look for specific patterns of white matter lesions on MRI scans that indicate inflammation. Because Acute Disseminated Encephalomyelitis can mimic other conditions, clinicians often utilize the following diagnostic criteria:
- Evidence of multifocal neurological symptoms (e.g., weakness, ataxia, or vision loss).
- MRI findings showing hyperintense lesions in the white matter.
- Absence of other underlying autoimmune or infectious diseases.
- A documented history of a preceding infection or immunization in the weeks prior to onset.
Is there support for those living with the condition?
Living with a diagnosis of Acute Disseminated Encephalomyelitis can be overwhelming for patients and their families due to the sudden onset of neurological symptoms. Currently, 80 people with Acute Disseminated Encephalomyelitis have joined the DiseaseMaps.org community to share their experiences and support one another through the recovery process. Connecting with others who understand the unique challenges of Acute Disseminated Encephalomyelitis can provide much-needed emotional clarity during the treatment and rehabilitation phases.
Next steps
- Consult a pediatric or adult neurologist specializing in neuroimmunology for a definitive diagnosis and management plan.
- Discuss high-dose corticosteroid therapy or intravenous immunoglobulin (IVIG) treatments with your care team.
- Join the community at DiseaseMaps.org to connect with other patients who have navigated the diagnosis of Acute Disseminated Encephalomyelitis.
- Maintain a detailed symptom diary to help your physician track neurological recovery.
