2021 ICD-10-CM Code G62.9

Code Classification

• Diseases of the nervous system (G00–G99)
  • Polyneuropathies and other disorders of the peripheral nervous system (G60-G65)
    • Other and unspecified polyneuropathies (G62)

Clinical Information

• DIABETIC NEUROPATHIES-. peripheral autonomic and cranial nerve disorders that are associated with diabetes mellitus. these conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves vasa nervorum. relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy see oculomotor nerve diseases; mononeuropathy; mononeuropathy multiplex; diabetic amyotrophy; a painful polyneuropathy; autonomic neuropathy; and thoracoabdominal neuropathy. from adams et al. principles of neurology 6th ed p1325
• POLYNEUROPATHIES-. diseases of multiple peripheral nerves simultaneously. polyneuropathies usually are characterized by symmetrical bilateral distal motor and sensory impairment with a graded increase in severity distally. the pathological processes affecting peripheral nerves include degeneration of the axon myelin or both. the various forms of polyneuropathy are categorized by the type of nerve affected e.g. sensory motor or autonomic by the distribution of nerve injury e.g. distal vs. proximal by nerve component primarily affected e.g. demyelinating vs. axonal by etiology or by pattern of inheritance.
• POEMS SYNDROME-. a multisystemic disorder characterized by a sensorimotor polyneuropathy polyneuropathies organomegaly endocrinopathy monoclonal gammopathy and pigmentary skin changes. other clinical features which may be present include edema; cachexia; microangiopathic glomerulopathy; pulmonary hypertension hypertension pulmonary; cutaneous necrosis; thrombocytosis; and polycythemia. this disorder is frequently associated with osteosclerotic myeloma. from adams et al. principles of neurology 6th ed p1335; rev med interne 1997;187:553 62
• AMYLOID NEUROPATHIES-. disorders of the peripheral nervous system associated with the deposition of amyloid in nerve tissue. familial primary nonfamilial and secondary forms have been described. some familial subtypes demonstrate an autosomal dominant pattern of inheritance. clinical manifestations include sensory loss mild weakness autonomic dysfunction and carpal tunnel syndrome. adams et al. principles of neurology 6th ed p1349
• ARSENIC POISONING-. disorders associated with acute or chronic exposure to compounds containing arsenic arsenicals which may be fatal. acute oral ingestion is associated with gastrointestinal symptoms and an encephalopathy which may manifest as seizures mental status changes and coma. chronic exposure is associated with mucosal irritation desquamating rash myalgias peripheral neuropathy and white transverse mees lines in the fingernails. adams et al. principles of neurology 6th ed p1212
• LEAD POISONING NERVOUS SYSTEM ADULT-. neurologic conditions in adults associated with acute or chronic exposure to lead or any of its salts. the most common lead related neurologic syndrome in adults consists of a polyneuropathy involving motor fibers. this tends to affect distal nerves and may present as wrist drop due to radial neuropathy. additional features of chronic lead exposure include anemia; constipation; colicky abdominal pain; a bluish lead line of the gums; interstitial nephritis nephritis interstitial; and saturnine gout. an encephalopathy may rarely occur. from adams et al. principles of neurology 6th ed p1212
• ALCOHOLIC NEUROPATHY-. a condition where damage to the peripheral nervous system including the peripheral elements of the autonomic nervous system is associated with chronic ingestion of alcoholic beverages. the disorder may be caused by a direct effect of alcohol an associated nutritional deficiency or a combination of factors. clinical manifestations include variable degrees of weakness; atrophy; paresthesias; pain; loss of reflexes; sensory loss; diaphoresis; and postural hypotension. from arch neurol 1995;521:45 51; adams et al. principles of neurology 6th ed p1146
• GUILLAIN BARRE SYNDROME-. an acute inflammatory autoimmune neuritis caused by t cell mediated cellular immune response directed towards peripheral myelin. demyelination occurs in peripheral nerves and nerve roots. the process is often preceded by a viral or bacterial infection surgery immunization lymphoma or exposure to toxins. common clinical manifestations include progressive weakness loss of sensation and loss of deep tendon reflexes. weakness of respiratory muscles and autonomic dysfunction may occur. from adams et al. principles of neurology 6th ed pp1312 1314
• POLYRADICULONEUROPATHY CHRONIC INFLAMMATORY DEMYELINATING-. a slowly progressive autoimmune demyelinating disease of peripheral nerves and nerve roots. clinical manifestations include weakness and sensory loss in the extremities and enlargement of peripheral nerves. the course may be relapsing remitting or demonstrate a step wise progression. protein is usually elevated in the spinal fluid and cranial nerves are typically spared. guillain barre syndrome features a relatively rapid progression of disease which distinguishes it from this condition. adams et al. principles of neurology 6th ed p1337
• PARANEOPLASTIC POLYNEUROPATHY-. a diffuse or multifocal peripheral neuropathy related to the remote effects of a neoplasm most often carcinoma or lymphoma. pathologically there are inflammatory changes in peripheral nerves. the most common clinical presentation is a symmetric distal mixed sensorimotor polyneuropathy. adams et al. principles of neurology 6th ed p1334
• AMYLOID NEUROPATHIES FAMILIAL-. inherited disorders of the peripheral nervous system associated with the deposition of amyloid in nerve tissue. the different clinical types based on symptoms correspond to the presence of a variety of mutations in several different proteins including transthyretin prealbumin; apolipoprotein a i; and gelsolin.

Convert G62.9 to ICD-9 Code

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code G62.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
