ICD-10 Code E78.1 – Pure hyperglyceridemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E78.1 – Pure hyperglyceridemia
What it is
E78.1 identifies pure hyperglyceridemia, a lipid disorder marked by elevated triglycerides in the blood. Use it when the record specifically documents this condition and not a broader mixed lipid abnormality.
Clinical signs
Clinical features vary; refer to documentation. Patients may be asymptomatic, and the diagnosis is often made from lipid testing or a provider’s assessment of elevated triglycerides.
When to use this code
Use E78.1 when the clinician documents pure hyperglyceridemia, hypertriglyceridemia, or an equivalent diagnosis without stating another lipid disorder. It may also fit when the note clearly identifies isolated triglyceride elevation. Check documentation if the record also mentions mixed dyslipidemia or secondary causes.
Do not use for
Do not use this code for mixed hyperlipidemia, hypercholesterolemia, or unspecified dyslipidemia. If the chart does not clearly support isolated triglyceride elevation, check documentation.
Coding tip
Code the condition only when the provider names it explicitly or documents isolated triglyceride elevation.
