E74 is a non-billable ICD-10-CM category code for other disorders of carbohydrate metabolism, so it cannot be submitted on claims. Use a more specific code from this category instead, such as E74.00, E74.01, E74.02, and E74.03.

  • Use E74.04 for McArdle disease

  • Use E74.05 for Lysosome-associated membrane protein 2 [LAMP2] deficiency

  • Use E74.09 for Other glycogen storage disease

  • E74.1 for Disorders of fructose metabolism

  • Use E74.10 for Disorder of fructose metabolism, unspecified

  • Use E74.11 for Essential fructosuria

  • Use E74.12 for Hereditary fructose intolerance

  • Use E74.19 for Other disorders of fructose metabolism

  • E74.2 for Disorders of galactose metabolism

  • Use E74.20 for Disorders of galactose metabolism, unspecified

  • Use E74.21 for Galactosemia

  • Use E74.29 for Other disorders of galactose metabolism

  • E74.3 for Other disorders of intestinal carbohydrate absorption

  • Use E74.31 for Sucrase-isomaltase deficiency

  • Use E74.39 for Other disorders of intestinal carbohydrate absorption

  • Use E74.4 for Disorders of pyruvate metabolism and gluconeogenesis

  • E74.8 for Other specified disorders of carbohydrate metabolism

  • E74.81 for Disorders of glucose transport, not elsewhere classified

  • E74.82 for Disorders of citrate metabolism

  • Use E74.89 for Other specified disorders of carbohydrate metabolism

  • Use E74.9 for Disorder of carbohydrate metabolism, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to E74: its own notes plus those printed at block E70-E88 and Chapter 4. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On E74 itself
From Block E70-E88 Metabolic disorders applies to 286 codes
  • androgen insensitivity syndrome (E34.5-)
  • congenital adrenal hyperplasia (E25.0)
  • hemolytic anemias attributable to enzyme disorders (D55.-)
  • Marfan syndrome (Q87.4-)
  • 5-alpha-reductase deficiency (E29.1)
From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • transitory endocrine and metabolic disorders specific to newborn (P70-P74)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Block E70-E88 Metabolic disorders applies to 286 codes
  • Ehlers-Danlos syndromes (Q79.6-)

Notes

General instructions on how these codes are used.

From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • All neoplasms, whether functionally active or not, are classified in Chapter 2. Appropriate codes in this chapter (i.e. E05.8, E07.0, E16-E31, E34.-) may be used as additional codes to indicate either functional activity by neoplasms and ectopic endocrine tissue or hyperfunction and hypofunction of endocrine glands associated with neoplasms and other conditions classified elsewhere.

Excludes1 2

These codes carry an Excludes1 note naming E74: they are not reported together with it, unless the two conditions are unrelated.

  • R79 Other abnormal findings of blood chemistry
    specific findings indicating disorder of carbohydrate metabolism (E73-E74) names E73-E74, which includes this code
  • Block R80-R82 Abnormal findings on examination of urine, without diagnosis
    specific findings indicating disorder of carbohydrate metabolism (E73-E74) names E73-E74, which includes this code

Patient EducationClinical

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.

Questions About E74Overview

What is the ICD-10 code for other disorders of carbohydrate metabolism?

E74 is the ICD-10-CM category for other disorders of carbohydrate metabolism, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is E74 (Other disorders of carbohydrate metabolism) a billable code?

No. This is a category header that groups the codes for other disorders of carbohydrate metabolism, and headers cannot be submitted on claims. Claims for other disorders of carbohydrate metabolism need a more specific code from this category, such as E74.00, E74.01, and E74.02.

Can E74 be reported with E16.2?

Not as a rule. The Excludes1 note on E74 lists "hypoglycemia NOS (E16.2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
