Clinical InformationClinical

  • Giant Axonal Neuropathy

    rare autosomal recessive disorder of intermediate filament proteins. the disease is caused by mutations in the gene that codes gigaxonin protein. the mutations result in disorganization of axonal neurofilament proteins, formation of the characteristic giant axons, and progressive neuropathy. the clinical features of the disease include early-onset progressive peripheral motor and sensory neuropathies often associated with central nervous system involvement (intellectual disability, seizures, dysmetria, and congenital nystagmus).

  • Waardenburg Syndrome

    rare, autosomal dominant disease with variable penetrance and several known clinical types. characteristics may include depigmentation of the hair and skin, congenital deafness, heterochromia iridis, medial eyebrow hyperplasia, hypertrophy of the nasal root, and especially dystopia canthorum. the underlying cause may be defective development of the neural crest (neurocristopathy). waardenburg's syndrome may be closely related to piebaldism. klein-waardenburg syndrome refers to a disorder that also includes upper limb abnormalities.

  • Small Fiber Neuropathy

    disorder of the peripheral nerves that primarily impair small nerve fibers. the affected small nerve fibers include myelinated a-delta fibers (see a fibers) and unmyelinated c fibers. because these small fibers innervate skin and help control autonomic function, their neuropathy presents with neuropathic pain, reduced thermal and pain sensitivity, and autonomic dysfunction (e.g. abnormal sweating or facial flushing). small fiber neuropathy can be idiopathic or associated with underlying diseases (e.g., amyloidosis; diabetes mellitus; sarcoidosis; or vasculitis).

  • GAN wt Allele|GAN1|Giant Axonal Neuropathy (Gigaxonin) Gene|Gigaxonin wt Allele|KLHL16

    human gan wild-type allele is located in the vicinity of 16q24.1 and is approximately 65 kb in length. this allele, which encodes gigaxonin protein, is involved in both ubiquitination and neurofilament structure. mutation of the gene is associated with giant axonal neuropathy.

  • Giant Axonal Neuropathy

    a rare inherited disorder affecting the neurofilaments. it is caused by mutations in the gan gene. it is characterized by the presence of abnormally large nerve cell axons. signs and symptoms include difficulty walking, sensory disturbances, lack of motor coordination and abnormal reflexes in the limbs.

  • Akinesia

    lack of movement.

  • Fetal Akinesia Deformation Sequence|FADS|Pena-Shokeir syndrome, Type 1

    a condition characterized by fetal akinesia and intrauterine growth restriction, that may be associated with mutation(s) in the rapsn or dok7 genes, encoding 43 kda receptor-associated protein of the synapse and protein dok-7, respectively.

  • Acute Motor and Sensory Axonal Neuropathy|Acute Motor And Sensory Axonal Neuropathy|Acute Motor-Sensory Axonal Neuropathy|Acute Motor-Sensory Axonal Neuropathy

    a subtype of guillain-barre syndrome that targets sensory motor axons, and is characterized by acute onset of quadriparesis, distal sensory loss, areflexia, and respiratory insufficiency.

  • Acute Motor Axonal Neuropathy|AMAN

    a subtype of guillain-barre syndrome that targets motor axons, and is characterized by symmetric limb weakness, diffuse areflexia, facial and oropharyngeal muscle weakness, and respiratory insufficiency.

  • Axonal Neuropathy

    any nerve disorder affecting the axon of a nerve.

  • Spinocerebellar Ataxia, Autosomal Recessive, with Axonal Neuropathy 2|AOA2|Ataxia with Oculomotor Apraxia Type 2|SCAN2

    an autosomal recessive condition caused by mutation(s) in the setx gene, encoding probable helicase senataxin. it is characterized by juvenile onset progressive cerebellar ataxia, axonal sensorimotor peripheral neuropathy, and increased concentrations of serum alpha-fetoprotein. oculomotor apraxia is common, but is not always present.

Patient EducationClinical

Peripheral Nerve Disorders

Nerves are like wires that carry messages back and forth between your brain and your body. Your peripheral nerves branch off from your brain and spinal cord and connect to all parts of your body, including your muscles and organs.

Questions About G60.8Overview

Is G60.8 (Hereditary and idiopathic neuropathy) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other hereditary and idiopathic neuropathies on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What is the ICD-9 equivalent of G60.8?

Under the General Equivalence Mappings, other hereditary and idiopathic neuropathies converts to ICD-9-CM 356.8 (idio periph neurpthy NEC). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
