ICD-10-CM Code For Disorders Of Lipoprotein Metabolism And Other Lipidemias: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group E78 includes disorders of lipoprotein metabolism and other lipidemias such as familial and nonfamilial hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, and other specified or unspecified disorders affecting cholesterol and triglyceride levels. These ICD-10-CM diagnosis codes are used to document clinical scenarios including primary and secondary lipid disorders, associated cardiovascular risk factors, and metabolic contributors affecting disease severity and management. Accurate coding within the ICD-10-CM E78 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM E78: Disorders Of Lipoprotein Metabolism And Other Lipidemias Overview

This group includes disorders of lipid and lipoprotein metabolism such as hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, and other specified and unspecified lipidemias that affect serum lipid levels and cardiovascular risk. These conditions target metabolic processes and the cardiovascular system by altering cholesterol and triglyceride profiles. Accurate coding matters for reimbursement because it links documented clinical severity and comorbidities to appropriate billing and claim processing.

When to Use

Use a code from this group when a patient is diagnosed with a primary or secondary lipid disorder documented in the medical record, including familial lipid disorders and drug- or disease-related dyslipidemias. Select the specific code that reflects the type of lipid abnormality, documented severity, and any associated conditions or complications.

Typical Clinical Scenarios

A middle-aged patient with a long history of poorly controlled type 2 diabetes and obesity presents for routine follow-up complaining of persistent xanthomas and fasting lipid panel showing markedly elevated LDL-C and mildly elevated triglycerides. The visit is for chronic management of dyslipidemia to reduce cardiovascular risk, and the clinician documents primary hypercholesterolemia as the principal lipid disorder. Typical codes: E78.00, E78.2
A young adult presents to the emergency department with acute pancreatitis confirmed by elevated lipase and abdominal imaging; recent labs reveal severely elevated triglycerides in the thousands mg/dL with a history of alcohol use and familial hypertriglyceridemia. The acute event is attributed to hypertriglyceridemia, so a disorder of elevated triglycerides is coded as the underlying metabolic cause contributing to the pancreatitis. Typical codes: E78.1, E78.2
An older patient with coronary artery disease and prior myocardial infarction comes to the cardiology clinic for medication reconciliation; lipid panel shows controlled LDL but ongoing low HDL and mixed dyslipidemia despite therapy, and the clinician documents other specified lipoprotein abnormalities as comorbidities impacting cardiovascular risk management. Typical codes: E78.49, E78.6
