What G14 covers · when clinicians use it
ICD-10 code G14 identifies Postpolio syndrome in the U.S. ICD-10-CM clinical and billing record set. It sits within the Nervous System chapter (G00–G99), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply G14 when an encounter's findings match the Postpolio syndrome description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify G14 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for G14 and is a coding reference, not clinical, diagnostic, or billing advice.
G14 refers to Postpolio syndrome, a group of neurodegenerative conditions that lead to progressive motor dysfunction, muscle wasting, and in some cases, cognitive decline. These disorders are typically genetic or post-infectious in nature and primarily affect the central nervous system (CNS).
Symptoms
- Involuntary movements – Especially in Huntington's disease (G10)
- Gait imbalance and coordination problems – Seen in hereditary ataxia (G11)
- Muscle weakness and atrophy – Common in spinal muscular atrophy (G12)
- CNS deterioration due to another disease – Characteristic of G13 conditions
- New-onset fatigue or weakness years after polio – Defining feature of postpolio syndrome (G14)
- Speech or swallowing difficulties – Often seen in later stages
- Spasticity or stiffness – Found across many progressive CNS atrophy syndromes
Diagnosis
Diagnosis of Postpolio syndrome involves genetic testing (especially for G10 and G11), MRI of the brain and spine, electromyography (EMG), clinical neurological exams, and functional assessments. A history of polio is critical in G14 diagnosis.
ICD10 Code Usage
ICD10 code G14 is used in neurology, neurogenetics, physical medicine and rehabilitation, and primary care. It supports care coordination, treatment planning, genetic counseling, disability certification, and long-term patient tracking for progressive neurological diseases.

FAQs
Q1: What is ICD10 code G14?
A: It refers to Postpolio syndrome, a neurodegenerative disorder primarily impacting motor function and often requiring lifelong support.
Q2: Are these disorders inherited?
A: Many, such as Huntington’s (G10) and ataxias (G11), are inherited, while G14 is a post-infectious condition.
Q3: Can these conditions be cured?
A: Currently, they are not curable, but early diagnosis and therapy can help manage symptoms and improve quality of life.
Q4: What treatments are available?
A: Physical therapy, occupational therapy, speech therapy, assistive devices, and medications for symptom relief.
Q5: Who manages care?
A: Neurologists, geneticists, rehabilitation specialists, physical therapists, and palliative care teams.
Conclusion
ICD10 code G14 enables accurate classification and management of Postpolio syndrome. It guides early intervention, genetic counseling, and coordinated care for individuals living with central nervous system atrophy syndromes.
