ICD-10 Code E77.8 – Other disorders of glycoprotein metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E77.8 – Other disorders of glycoprotein metabolism
What it is
E77.8 identifies other specified disorders affecting glycoprotein metabolism. Use it when the record documents a glycoprotein-related metabolic disorder that does not fit a more specific ICD-10-CM code.
Clinical signs
Clinical features vary; refer to documentation. Depending on the disorder, notes may mention abnormal glycoprotein processing, multisystem involvement, developmental issues, or organ-specific findings.
When to use this code
Use E77.8 when the clinician clearly documents a glycoprotein metabolism disorder and no more specific code is available. It is appropriate for confirmed diagnoses, problem lists, or discharge summaries that name the condition. If the documentation is vague, check documentation before coding.
Do not use for
Do not use this code for unrelated carbohydrate, lipid, or general metabolic disorders. Also avoid it when a more specific inherited storage or glycosylation disorder is documented.
Coding tip
Match the exact wording in the chart and code the most specific glycoprotein disorder documented.
