The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

CCSR Code: NVS002

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

inflammation of the spinal cord. relatively common etiologies include infections; autoimmune diseases; spinal cord; and ischemia (see also spinal cord vascular diseases). clinical features generally include weakness, sensory loss, localized pain, incontinence, and other signs of autonomic dysfunction.

inflammation of a transverse portion of the spinal cord characterized by acute or subacute segmental demyelination or necrosis. the condition may occur sporadically, follow an infection or vaccination, or present as a paraneoplastic syndrome (see also encephalomyelitis, acute disseminated). clinical manifestations include motor weakness, sensory loss, and incontinence. (adams et al., principles of neurology, 6th ed, pp1242-6)

schistosomiasis of the brain, spinal cord, or meninges caused by infections with trematodes of the genus schistosoma (primarily schistosoma japonicum; schistosoma mansoni; and schistosoma haematobium in humans). s. japonicum infections of the nervous system may cause an acute meningoencephalitis or a chronic encephalopathy. s. mansoni and s. haematobium nervous system infections are associated with acute transverse myelitis involving the lower portions of the spinal cord. (from joynt, clinical neurology, 1998, ch27, pp61-2)

a disorder characterized by an infectious or inflammatory process involving the brain and spinal cord tissues.

moderate weakness or sensory loss; limiting instrumental adl or mild/moderate impact on age-appropriate normal daily activity (pediatric)

iv antibiotic, antifungal, or antiviral intervention indicated; steroid therapy indicated; severe changes in mental status; self-limited seizure activity; neurologic abnormalities

severe weakness or sensory loss; limiting self-care adl or severe impact on age-appropriate normal daily activity (pediatric)

life-threatening consequences; urgent intervention indicated

death

an inflammatory process affecting the central nervous system. it is characterized by perivascular demyelination. symptoms usually follow an acute viral infection or immunization and include fever, confusion, somnolence and involuntary movements. it may lead to coma and death.

an acute onset of focal limb weakness that is associated mainly with gray matter abnormalities or csf pleocytosis, but which is without an apparent cause.

an acute infectious disorder that affects the nervous system. it is caused by the poliovirus. the virus spreads by direct contact, and can be prevented by prophylaxis with the polio vaccine.

a neurologic disorder that is caused by inflammation across both sides of one level, or segment, of the spinal cord. (from ninds)

evidence of acute transverse myelitis in demyelinating disease of the central nervous system.

a syndrome of unknown etiology. chronic fatigue syndrome (cfs) is a clinical diagnosis characterized by an unexplained persistent or relapsing chronic fatigue that is of at least six months' duration, is not the result of ongoing exertion, is not substantially alleviated by rest, and results in substantial reduction of previous levels of occupational, educational, social, or personal activities. common concurrent symptoms of at least six months duration include impairment of memory or concentration, diffuse pain, sore throat, tender lymph nodes, headaches of a new type, pattern, or severity, and nonrestorative sleep. the etiology of cfs may be viral or immunologic. neurasthenia and fibromyalgia may represent related disorders. also known as myalgic encephalomyelitis.

an autoinflammatory disease characterized by sterile bone lesions which are multifocal and/or recurrent.

a vaccine consisting of detoxified diphtheria toxoid (d), detoxified tetanus toxoid (t), acellular pertussis (ap) antigens, inactivated poliovirus (ipv) types 1, 2 and 3, and haemophilus influenzae type b (hib) capsular polysaccharide (polyribosylribitol phosphate; prp) covalently bound to tetanus protein, suspended in water for injection and with active immunizing activity against diphtheria, tetanus, pertussis, poliomyelitis and h. influenzae type b. the five purified pertussis antigens in this vaccine are pertussis toxin (pt), filamentous hemagglutinin (fha), pertactin (prn) and fimbriae types 2 and 3 (fim). upon intramuscular injection of the diphtheria-tetanus-acellular pertussis-inactivated poliomyelitis-haemophilus influenzae type b vaccine (dtap-ipv-hib), this vaccine activates the immune system to develop antibodies against diphtheria toxin, tetanus toxin, b. pertussis antigens, polioviruses and hib, thereby providing active immunization against these diseases. the diphtheria and tetanus toxoids and pertussis antigens (inactivated pt, fha, prn and fim) are adsorbed separately onto aluminum phosphate and then combined with ipv and prp.

inflammation of the brain and the spinal cord.

a disorder characterized by an infectious process involving the brain and spinal cord tissues.

an autoimmune demyelinating disease of the central nervous system that is produced experimentally in animals by the injection of homogenized brain or spinal cord in freund's adjuvant. myelin basic protein appears to be the antigen that elicits the hypersensitivity immune response which is characterized by focal areas of lymphocyte and macrophage infiltration into the brain, associated with demyelination and destruction of the blood-brain barrier. experimental allergic encephalomyelitis (eae) is used as an animal model for demyelinating diseases of the human central nervous system such as multiple sclerosis.

asymptomatic; mild signs (e.g., babinski's reflex or lhermitte's sign)

moderate weakness or sensory loss; limiting instrumental adl

iv antibiotic, antifungal, or antiviral intervention indicated; invasive intervention indicated

severe weakness or sensory loss; limiting self care adl

life-threatening consequences; urgent intervention indicated

life-threatening consequences; urgent intervention indicated

death

death

an infectious process that affects the brain and spinal cord tissues. it is usually caused by viruses.

an inflammatory process affecting the spinal cord. causes include viral infections, autoimmune disorders, vascular disorders, and toxic agents. symptoms include weakness, paresthesia, sensory loss, pain, and incontinence.

a disorder characterized by inflammation involving the spinal cord. symptoms include weakness, paresthesia, sensory loss, marked discomfort and incontinence.

an autoimmune inflammatory syndrome characterized by optic neuritis and myelitis. signs and symptoms include loss of vision, weakness and paralysis of the extremities, and loss of sensation.

an acute or chronic inflammation of the bone and its structures due to infection with pyogenic bacteria.

osteomyelitis resulting from an infection with staphylococcus.

evidence of subacute necrotizing myelitis of central nervous system.

a rare, paralytic poliomyelitis associated with the orally administered live attenuated strain of the poliovirus, opv.

a mosquito-born viral infection caused by the western equine encephalitis virus. the signs and symptoms range from flu-like illness to permanent central nervous system damage, coma, and death.

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.

Spinal Cord Diseases

Your spinal cord is a bundle of nerves that runs down the middle of your back. It carries signals back and forth between your body and your brain. It is protected by your vertebrae, which are the bone disks that make up your spine. If you have an accident that damages the vertebrae or other parts of the spine, this can also injure the spinal cord. Other spinal cord problems include:

Symptoms vary but might include pain, numbness, loss of sensation and muscle weakness. These symptoms can occur around the spinal cord, and also in other areas such as your arms and legs. Treatments often include medicines and surgery.
