2024 ICD-10-CM Diagnosis Code E75.02

Approximate Synonyms

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

• B variant hexosaminidase A deficiency
• B variant hexosaminidase A deficiency - adult
• B variant hexosaminidase A deficiency - infantile
• B variant hexosaminidase A deficiency - juvenile
• B1 variant hexosaminidase A deficiency
• Tay-Sachs disease
• Tay-Sachs disease, variant AB

Convert E75.02 to ICD-9-CM

• ICD-9-CM Code: 330.1 - Cerebral lipidoses
  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.

Tay-Sachs Disease

Tay-Sachs disease is a rare, inherited disease. It is a type of lipid metabolism disorder. It causes too much of a fatty substance to build up in the brain. This buildup destroys nerve cells, causing mental and physical problems.

Infants with Tay-Sachs disease appear to develop normally for the first few months of life. Then mental and physical abilities decline. The child becomes blind, deaf, and unable to swallow. Muscles begin to waste away and paralysis sets in. Even with the best of care, children with Tay-Sachs disease usually die by age 4.

The cause is a gene mutation which is most common in Eastern European Ashkenazi Jews. To get the disease, both parents must have the gene. If they do, there is a 25% chance of the child having the disease. A blood test and prenatal tests can check for the gene or the disease.

There is no cure. Medicines and good nutrition can help some symptoms. Some children need feeding tubes.

Tay-Sachs disease

Tay-Sachs disease is a rare, inherited disorder that is characterized by neurological problems caused by  the death of nerve cells (neurons) in the brain and spinal cord (central nervous system).

The most common form of Tay-Sachs disease, known as infantile Tay-Sachs disease, becomes apparent early in life. Infants with this disorder typically develop normally until they are 3 to 6 months old. During this time, their development slows and muscles used for movement weaken. Affected infants stop achieving normal developmental milestones and begin to lose previously acquired skills such as turning over, sitting, and crawling. Infants with this condition develop an exaggerated startle reaction to loud noises. As the disease progresses, children with Tay-Sachs disease experience involuntary muscle twitches (myoclonic jerks), seizures, difficulty swallowing (dysphagia), vision and hearing loss, and intellectual disability. An eye abnormality called a cherry-red spot, which is identified by eye examination, is characteristic of this disorder. Children with infantile  Tay-Sachs disease usually live only into early childhood.

Two other forms of Tay-Sachs disease, known as juvenile and late-onset, are rare. Signs and symptoms of the juvenile form can appear between the ages of 5 years and late adolescence. Features of late-onset Tay-Sachs disease typically appear in adulthood. People with either of these forms of the condition usually have milder and more variable signs and symptoms than those with the infantile form. Characteristic features of juvenile or late-onset Tay-Saches disease include muscle weakness, loss of muscle coordination (ataxia), speech problems, and psychiatric symptoms. These signs and symptoms vary widely among people with late-onset forms of Tay-Sachs disease.
