2022 ICD-10-CM Code E74.8

Other specified disorders of carbohydrate metabolism

Version 2021

Not Valid for Submission

ICD-10:E74.8
Short Description:Other specified disorders of carbohydrate metabolism
Long Description:Other specified disorders of carbohydrate metabolism

Code Classification

  • Endocrine, nutritional and metabolic diseases (E00–E90)
    • Metabolic disorders (E70-E88)
      • Other disorders of carbohydrate metabolism (E74)

E74.8 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other specified disorders of carbohydrate metabolism. The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding for Other specified disorders of carbohydrate metabolism

Non-specific codes like E74.8 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for other specified disorders of carbohydrate metabolism:

  • NON-BILLABLE CODE - E74.81 for Disorders of glucose transport, not elsewhere classified
  • BILLABLE CODE - Use E74.810 for Glucose transporter protein type 1 deficiency
  • BILLABLE CODE - Use E74.818 for Other disorders of glucose transport
  • BILLABLE CODE - Use E74.819 for Disorders of glucose transport, unspecified
  • BILLABLE CODE - Use E74.89 for Other specified disorders of carbohydrate metabolism

Convert E74.8 to ICD-9 Code

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code E74.8 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients


Carbohydrate Metabolism Disorders

Metabolism is the process your body uses to make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system (enzymes) 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. If you have a metabolic disorder, something goes wrong with this process.

Carbohydrate metabolism disorders are a group of metabolic disorders. Normally your enzymes break carbohydrates down into glucose (a type of sugar). If you have one of these disorders, you may not have enough enzymes to break down the carbohydrates. Or the enzymes may not work properly. This causes a harmful amount of sugar to build up in your body. That can lead to health problems, some of which can be serious. Some of the disorders are fatal.

These disorders are inherited. Newborn babies get screened for many of them, using blood tests. If there is a family history of one of these disorders, parents can get genetic testing to see whether they carry the gene. Other genetic tests can tell whether the fetus has the disorder or carries the gene for the disorder.

Treatments may include special diets, supplements, and medicines. Some babies may also need additional treatments, if there are complications. For some disorders, there is no cure, but treatments may help with symptoms.
