F79 - Unspecified intellectual disabilities
|Short Description:||Unspecified intellectual disabilities|
|Long Description:||Unspecified intellectual disabilities|
|Status:||Valid for Submission|
F79 is a billable ICD-10 code used to specify a medical diagnosis of unspecified intellectual disabilities. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like F79 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- 11p partial monosomy syndrome

- WAGR syndrome
- White matter hypoplasia, corpus callosum agenesis, intellectual disability syndrome
- White Sutton syndrome
- Hypertelorism-. abnormal increase in the interorbital distance due to overdevelopment of the lesser wings of the sphenoid.
- Athetosis-. a dyskinesia characterized by an inability to maintain the fingers, toes, tongue, or other body parts in a stable position, resulting in continuous slow, sinusoidal, and flowing involuntary movements. this condition is frequently accompanied by chorea, where it is referred to as choreoathetosis. athetosis may occur as a manifestation of basal ganglia diseases or drug toxicity. (from adams et al., principles of neurology, 6th ed, p76)
- 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.
- Athetosis-. slow, involuntary, and nonpurposeful writhing movements that usually affect the upper limbs.
- Choreoathetosis|Choreathetosis-. abnormal movement characterized by involuntary jerking and writhing affecting the limbs, trunk, and facial muscles.
- Infantile Convulsions and Paroxysmal Choreoathetosis, Familial|ICCA|ICCA Syndrome|PKD/IC|Paroxysmal Kinesigenic Dyskinesia with Infantile Convulsions-. an autosomal dominant inherited disorder caused by mutation(s) in the prrt2 gene, encoding proline-rich transmembrane protein 2. it is characterized by epileptic seizures and paroxysmal kinesigenic choreoathetosis. it shares features with episodic kinesigenic dyskinesia-1, which is an allelic disorder.
- Athetoid Cerebral Palsy-. a subtype of cerebral palsy characterized by involuntary, purposeless writhing movements which affect the hands, feet, arms, and legs; the face and tongue may be affected as well, leading to involuntary grimacing, drooling, dysarthria and difficulty eating.
- 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.

These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Mental deficiency NOS

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.
