Clinical Information

• Intellectual Disability

  subnormal intellectual functioning which originates during the developmental period. this has multiple potential etiologies, including genetic defects and perinatal insults. intelligence quotient (iq) scores are commonly used to determine whether an individual has an intellectual disability. iq scores between 70 and 79 are in the borderline range. scores below 67 are in the disabled range. (from joynt, clinical neurology, 1992, ch55, p28)

• Hypertelorism

  abnormal increase in the interorbital distance due to overdevelopment of the lesser wings of the sphenoid.

• Arachnodactyly

  an abnormal bone development that is characterized by extra long and slender hands and fingers, such that the clenched thumb extends beyond the ulnar side of the hand. arachnodactyly can include feet and toes. arachnodactyly has been associated with several gene mutations and syndromes.

• WAGR Syndrome

  a contiguous gene syndrome associated with hemizygous deletions of chromosome region 11p13. the condition is marked by the combination of wilms tumor; aniridia; genitourinary abnormalities; and intellectual disability.

• Congenital Hepatic Fibrosis

  a congenital disorder usually inherited in an autosomal recessive pattern. it affects the hepatobiliary system and the kidneys. it is characterized by liver fibrosis, portal hypertension, and renal cysts.

Convert F79 to ICD-9-CM

• ICD-9-CM Code: 319 - Intellect disability NOS
  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.

Patient Education

Developmental Disabilities

Developmental disabilities are severe, long-term problems. They may be physical, such as blindness. They may affect mental ability, such as learning disabilities. Or the problem can be both physical and mental, such as Down syndrome. The problems are usually life-long, and can affect everyday living.

There are many causes of developmental disabilities, including:

• Genetic or chromosome abnormalities. These cause conditions such as Down syndrome and Rett syndrome.
• Prenatal exposure to substances. For example, drinking alcohol when pregnant can cause fetal alcohol spectrum disorders.
• Certain infections in pregnancy
• Preterm birth

Often there is no cure, but treatment can help the symptoms. Treatments include physical, speech, and occupational therapy. Special education classes and psychological counseling can also help.
