The primary ICD-10 code for Glycogen Storage Disease is E74.0, while the corresponding ICD-9 code is 271.0. Because Glycogen Storage Disease is a group of over 15 distinct metabolic disorders, these codes serve as umbrella classifications for various sub-types, such as Von Gierke disease or Pompe disease. What exactly is Glycogen Storage Disease? Glycogen Storage Disease (GSD) refers to a group of rare metabolic disorders caused by genetic defects that affect the body's ability to create or break down glycogen, a form of sugar stored in the liver and muscles.

Glycogen Storage Disease (GSD) refers to a group of rare metabolic disorders caused by genetic defects that affect the body's ability to create or break down glycogen, a form of sugar stored in the liver and muscles. Because the body cannot properly manage these energy stores, individuals with Glycogen Storage Disease may experience severe hypoglycemia, muscle weakness, or organ enlargement depending on the specific enzyme deficiency involved. With 379 members on DiseaseMaps.org, our community highlights the diverse ways this condition manifests, ranging from infantile-onset forms to milder adult-onset presentations.
In clinical practice, ICD-10 code E74.0 is the foundational category for Glycogen Storage Disease. However, because the clinical needs vary drastically between types, physicians often utilize more specific sub-codes to ensure accurate medical billing and treatment tracking. For example, GSD Type I (Von Gierke disease) is specifically mapped to E74.01, whereas GSD Type II (Pompe disease) is categorized under E74.02. Understanding these codes is essential for patients navigating insurance coverage and accessing specialized metabolic care.
Yes, Glycogen Storage Disease is a genetic condition. Most forms of Glycogen Storage Disease are inherited in an autosomal recessive pattern, meaning an individual must inherit two copies of the mutated gene—one from each parent—to manifest the disease. Genetic counseling is a critical component of care for families impacted by this condition, as it provides clarity on recurrence risks and family planning.
While there are many subtypes, medical professionals generally categorize Glycogen Storage Disease based on the tissue primarily affected and the specific enzyme that is missing. The following list outlines some of the most common clinical classifications:
