Demyelinating diseases of the central nervous system (G35-G37)

ICD-10 codes G35-G37 cover a group of disorders known as demyelinating diseases of the central nervous system, where the protective covering of nerve fibers is damaged. These codes are specifically used to classify conditions like multiple sclerosis (G35) and other less common but related acute or chronic demyelinating diseases.

This range highlights multiple sclerosis (MS) at code G35, including types such as relapsing remitting, primary progressive, and pediatric MS, along with associated symptoms like optic neuritis and central neuropathic pain. Code G36 includes acute disseminated demyelination disorders such as neuromyelitis optica (G36.0) and hemorrhagic leukoencephalitis (G36.1). The G37 series covers other specific demyelinating conditions like Schilder's disease (G37.0), central pontine myelinolysis (G37.2), and acute transverse myelitis (G37.3). It also contains codes for rarer diseases including Balo concentric sclerosis (G37.5) and the myelin oligodendrocyte glycoprotein antibody disease (G37.81). These codes help identify various demyelinating illnesses for accurate diagnosis, treatment planning, and insurance claims processing.
