Code Classification

  • Diseases of the nervous system
    (G00–G99)
    • Systemic atrophies primarily affecting the central nervous system
      (G10-G14)
      • Spinal muscular atrophy and related syndromes
        (G12)

G12.24 is a billable diagnosis code used to specify a medical diagnosis of familial motor neuron disease. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Autosomal recessive lower motor neuron disease with childhood onset
  • Distal spinal muscular atrophy
  • Hereditary motor neuron disease
  • Lower motor neuron syndrome with late-adult onset

Clinical Classification

Clinical Information

  • Amyotrophic Lateral Sclerosis

    a degenerative disorder affecting upper motor neurons in the brain and lower motor neurons in the brain stem and spinal cord. disease onset is usually after the age of 50 and the process is usually fatal within 3 to 6 years. clinical manifestations include progressive weakness, atrophy, fasciculation, hyperreflexia, dysarthria, dysphagia, and eventual paralysis of respiratory function. pathologic features include the replacement of motor neurons with fibrous astrocytes and atrophy of anterior spinal nerve roots and corticospinal tracts. (from adams et al., principles of neurology, 6th ed, pp1089-94)
  • Motor Neuron Disease

    diseases characterized by a selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. clinical subtypes are distinguished by the major site of degeneration. in amyotrophic lateral sclerosis there is involvement of upper, lower, and brainstem motor neurons. in progressive muscular atrophy and related syndromes (see muscular atrophy, spinal) the motor neurons in the spinal cord are primarily affected. with progressive bulbar palsy (bulbar palsy, progressive), the initial degeneration occurs in the brainstem. in primary lateral sclerosis, the cortical neurons are affected in isolation. (adams et al., principles of neurology, 6th ed, p1089)

Replacement Code

G1224 replaces the following previously assigned ICD-10-CM code(s):

  • G12.29 - Other motor neuron disease

Convert G12.24 to ICD-9-CM

  • ICD-9-CM Code: 335.29 - Motor neuron disease NEC
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

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.
