Inclusion Terms
- Deficiency of phosphoenolpyruvate carboxykinase
- Deficiency of pyruvate carboxylase
- Deficiency of pyruvate dehydrogenase
Type 1 Excludes
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.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

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.

Questions About E74.4Overview
Is E74.4 (Other disorders of carbohydrate metabolism) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report disorders of pyruvate metabolism and gluconeogenesis on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What is the ICD-9 equivalent of E74.4?
Under the General Equivalence Mappings, disorders of pyruvate metabolism and gluconeogenesis converts to ICD-9-CM 271.0 (glycogenosis) and 271.8 (dis carbohydr metab NEC). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:
- The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
- The condition places limitations on self-care, independent living, and social interactions.
