ICD-10-CM Code E79.8

Other disorders of purine and pyrimidine metabolism

Version 2021 Billable Code

Valid for Submission

E79.8 is a billable code used to specify a medical diagnosis of other disorders of purine and pyrimidine metabolism. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code E79.8 might also be used to specify conditions or terms like 5-amino-4-imidazole carboxamide ribosiduria, adenine phosphoribosyl transferase deficiency type i, adenine phosphoribosyl transferase deficiency type ii, adenylosuccinate lyase deficiency, aprt deficiency, japanese type, beta-aminoisobutyricaciduria, etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code E79.8:

Inclusion Terms

Inclusion Terms
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.

Information for Patients

Metabolic Disorders

Metabolism is the process your body uses to get or make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system break the food parts down into sugars and acids, your body's fuel. Your body can use this fuel right away, or it can store the energy in your body tissues, such as your liver, muscles, and body fat.

A metabolic disorder occurs when abnormal chemical reactions in your body disrupt this process. When this happens, you might have too much of some substances or too little of other ones that you need to stay healthy. There are different groups of disorders. Some affect the breakdown of amino acids, carbohydrates, or lipids. Another group, mitochondrial diseases, affects the parts of the cells that produce the energy.

You can develop a metabolic disorder when some organs, such as your liver or pancreas, become diseased or do not function normally. Diabetes is an example.
