Used for medical claim reporting in all healthcare settings, ICD-10-CM is a standardized classification system of diagnosis codes that represent conditions and diseases, related health problems, abnormal findings, signs and symptoms, injuries, external causes of injuries and diseases, and social circumstances.

Acute disseminated encephalomyelitis (ADEM) is characterized by a brief but widespread attack of inflammation in the brain and spinal cord that damages myelin – the protective covering of nerve fibers. ADEM often follows viral or bacterial infections, or less often, vaccination for measles, mumps, or rubella.
Acute disseminated encephalomyelitis (ADEM) is a neurological, immune-mediated disorder in which widespread inflammation of the brain and spinal cord damages tissue known as white matter. White matter is tissue composed of nerve fibers, many of which are covered by a collection of fats and proteins known as myelin.
ADEM is an "autoimmune" condition that often occurs after a child has an infection, such as a cold. The immune system protects the body from invaders, like bacteria and viruses. Autoimmune diseases confuse the body's immune system. Instead of fighting against bacteria or viruses, it attacks healthy cells and tissues.
Symptoms and Causes We know that ADEM usually follows an infection of some kind. In 50 to 75 percent of cases, the beginning of the disease is preceded by a viral or bacterial infection, usually a sore throat or cough (upper respiratory tract infection).
ADEM generally consists of a single attack, while MS involves multiple attacks. In this instance, an MRI of the brain can help. MRIs can differentiate between older and newer lesions. The presence of multiple older lesions on the brain is more consistent with MS.
How is ADEM different from MS? In most but not all cases, ADEM occurs only once, while patients with MS have further, repeated attacks of inflammation in their brains and spinal cords.
Dr. Pitt told NBC that there have been dozens of case reports pinpointing COVID-19 as the trigger for ADEM.
Inflammation of the meninges, the membranes that surround the brain and spinal cord, is called meningitis; inflammation of the brain itself is called encephalitis. Myelitis refers to inflammation of the spinal cord. When both the brain and the spinal cord are involved, the condition is called encephalomyelitis.
A wide variety of precipitating factors can trigger ADEM, and it has long been known to be a rare adverse event following some types of vaccinations. Recently, ADEM has also been associated with COVID-19 infection and (very rarely) with COVID-19 vaccination.
ADEM Diagnosis and Tests No one test can spot ADEM. Doctors most often diagnose it with MRI (pictures of your brain made with a large magnet and radio waves) and a lumbar puncture (fluid drawn from around the spinal cord and then tested). Your doctor will try to rule out conditions with similar symptoms.
More than 85 percent of people with ADEM recover fully within a few weeks. Most others recover within a few months. Steroid treatments can shorten the duration of an attack.
An important differential diagnosis of ADEM is mild encephalopathy with reversible splenial lesion (MERS), this entity is a clinico-radiological syndrome characterized by a transient mild encephalopathy and a reversible lesion in the splenium of the corpus callosum on MRI.
Acute disseminated encephalomyelitis (ADEM), or acute demyelinating encephalomyelitis, is a rare autoimmune disease marked by a sudden, widespread attack of inflammation in the brain and spinal cord.
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here."
