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)

G62.9 is a billable diagnosis code used to specify a medical diagnosis of polyneuropathy, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like G62.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Lyme Neuroborreliosis

    nervous system infections caused by tick-borne spirochetes of the borrelia burgdorferi group. the disease may affect elements of the central or peripheral nervous system in isolation or in combination. common clinical manifestations include a lymphocytic meningitis, cranial neuropathy (most often a facial neuropathy), polyradiculopathy, and a mild loss of memory and other cognitive functions. less often more extensive inflammation involving the central nervous system (encephalomyelitis) may occur. in the peripheral nervous system, b. burgdorferi infection is associated with mononeuritis multiplex and polyradiculoneuritis. (from j neurol sci 1998 jan 8;153(2):182-91)
  • 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)
  • Polyradiculopathy

    disease or injury involving multiple spinal nerve roots. polyradiculitis refers to inflammation of multiple spinal nerve roots.
  • 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)
  • Spinal Nerve Roots

    paired bundles of nerve fibers entering and leaving the spinal cord at each segment. the dorsal and ventral nerve roots join to form the mixed segmental spinal nerves. the dorsal roots are generally afferent, formed by the central projections of the spinal (dorsal root) ganglia sensory cells, and the ventral roots are efferent, comprising the axons of spinal motor and preganglionic autonomic fibers.
  • Alcoholic Polyneuropathy|Alcoholic polyneuropathy

    any disease affecting more than one nerve.
  • Chronic Inflammatory Demyelinating Polyneuropathy|CIDP|Chronic Inflammatory Demyelinating Polyneuritis|Chronic Inflammatory Demyelinating Polyradiculoneuropathy

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
