Short answer · Medically reviewed summary · Last updated: 2026-05-08
Benign Hereditary Chorea (BHC) does not have a unique, dedicated ICD-10 or ICD-9 code; it is typically classified under broader categories for chorea or hereditary extrapyramidal diseases. For medical billing and documentation, clinicians often utilize ICD-10 code G25.5 (Other chorea) and ICD-9 code 333.5 (Other chorea) to represent the clinical manifestation of Benign Hereditary Chorea. What is the clinical nature of Benign Hereditary Chorea? Benign Hereditary Chorea (BHC) is a rare, non-progressive movement disorder characterized by involuntary, jerky movements that typically begin in early childhood.

What is the clinical nature of Benign Hereditary Chorea?
Benign Hereditary Chorea (BHC) is a rare, non-progressive movement disorder characterized by involuntary, jerky movements that typically begin in early childhood. Unlike other choreiform disorders, the symptoms of Benign Hereditary Chorea generally remain stable or may even improve slightly as the patient reaches adulthood. At DiseaseMaps.org, we recognize the unique journey of those living with this condition, including the 2 community members who have shared their experiences.
How is Benign Hereditary Chorea diagnosed?
Diagnosing Benign Hereditary Chorea involves a combination of clinical neurological examination, family history, and genetic testing. Because there is no specific ICD code for Benign Hereditary Chorea, doctors must rely on clinical criteria to distinguish it from progressive conditions like Huntington’s disease. Key features include:
- Onset in infancy or early childhood (often before age 5).
- Non-progressive clinical course throughout the patient's life.
- Autosomal dominant inheritance pattern associated with mutations in the NKX2-1 gene.
- Normal cognitive development in the majority of cases.
Is Benign Hereditary Chorea hereditary?
Yes, Benign Hereditary Chorea is a genetic condition inherited in an autosomal dominant manner. This means that an individual with Benign Hereditary Chorea has a 50% chance of passing the causative NKX2-1 gene mutation to each of their children. Genetic counseling is strongly recommended for families affected by Benign Hereditary Chorea to understand the recurrence risks and available testing options.
Next steps
- Consult a movement disorder specialist or pediatric neurologist for a definitive diagnosis.
- Request a referral to a clinical geneticist for NKX2-1 gene sequencing.
- Connect with others by joining the community at DiseaseMaps.org to share insights on managing Benign Hereditary Chorea.
- Monitor for potential associated features, such as hypothyroidism or pulmonary issues, which can occur in NKX2-1-related disorders.
