Decoding Hyperlipidemia: Types of ICD-10 Codes and Coding Precision
Hyperlipidemia, also known as high blood cholesterol, is a common condition that affects millions of people worldwide. Hyperlipidemia is often a silent condition, meaning that there may be no symptoms until it has caused serious damage to the arteries. This is why it is important to be aware of your risk factors for hyperlipidemia and to get regular screenings.
In this blog, we will explore knowledge and solutions to navigate it confidently.By raising awareness about hyperlipidemia, we can encourage early detection, prevention, and treatment, leading to improved cardiovascular health and overall well-being.
What are the ICD-10 codes for Hyperlipidemia?
Hyperlipidemia is a common medical condition characterized by elevated levels of lipids (such as cholesterol and triglycerides) in the blood. In ICD-10, hyperlipidemia is classified under the “E” category, which includes endocrine, nutritional, and metabolic diseases. Hyperlipidemia encompasses various types and subtypes, each with its own ICD-10 codes.
Selecting the correct code requires a thorough understanding of the condition and its classification. That’s why physicians prefer to rely on medical coding and billing services to ensure accurate and precise reporting of hyperlipidemia and other conditions.
Outsourcing companies providing these services employ coding specialists who have expertise in medical coding and can accurately assign the appropriate ICD-10 codes based on the provided medical documentation.
What is hyperlipidemia?
Hyperlipidemia is a medical term for abnormally high levels of fats (lipids) in the blood, which include cholesterol and triglycerides. These lipids are essential for various bodily functions, but excessive levels can accumulate in the arteries, increasing the risk of heart disease, stroke, and other cardiovascular complications.
Hyperlipidemia often develops without any noticeable symptoms, making it crucial for regular screenings and early detection.
Common types of hyperlipidemia
There are five main types of hyperlipidemia:
1. Pure hypercholesterolemia
This type of hyperlipidemia is characterized by elevated levels of cholesterol, particularly LDL (low-density lipoprotein) cholesterol, without a significant increase in triglyceride levels. LDL cholesterol is often referred to as “bad” cholesterol because it can accumulate in the arteries and contribute to plaque formation, a major risk factor for heart disease and stroke.
2. Pure hyperglyceridemia
This type of hyperlipidemia is characterized by elevated levels of triglycerides without a significant increase in cholesterol levels. Triglycerides are the main form of fat stored in the body. When consumed in excess, they can be converted to LDL cholesterol, increasing the risk of cardiovascular disease.
3. Mixed hyperlipidemia
This is the most common type of hyperlipidemia and involves elevated levels of both cholesterol and triglycerides. Mixed hyperlipidemia presents a higher risk of cardiovascular complications than either pure hypercholesterolemia or pure hyperglyceridemia.

4. Familial hypercholesterolemia (FH)
FH is an inherited genetic disorder that causes high levels of LDL cholesterol from an early age. Individuals with FH are at an increased risk of developing heart disease and stroke at a young age.
5. Secondary hyperlipidemia
This type of hyperlipidemia is caused by an underlying medical condition, such as diabetes, hypothyroidism, or certain medications. Once the underlying condition is addressed, secondary hyperlipidemia may improve or resolve.
The difference between Hyperlipidemia from Dyslipidemia
The terms hyperlipidemia and dyslipidemia are often used interchangeably, but they have slightly different meanings. Hyperlipidemia refers to any condition in which the levels of lipids (fats) in the blood are too high. This can include cholesterol, triglycerides, or both.
Dyslipidemia, on the other hand, refers to any abnormality in the levels of lipids in the blood, including high levels, low levels, or an imbalance between different types of lipids.
In other words, hyperlipidemia is a broader term that encompasses all conditions in which lipid levels are too high, while dyslipidemia is a more specific term that refers to any abnormality in lipid levels, including high levels, low levels, or an imbalance.
The two terms are often used interchangeably because the distinction between them is not always clear-cut. In some cases, a person may have both hyperlipidemia and dyslipidemia. For example, a person with high cholesterol and low HDL (good) cholesterol would have hyperlipidemia, but they would also have dyslipidemia because their HDL levels are too low.
The ICD-10 codes for hyperlipidemia are:
- E78.00: Pure hypercholesterolemia, unspecified
- E78.01: Familial hypercholesterolemia
- E78.1: Pure hyperglyceridemia
- E78.2: Mixed hyperlipidemia
- E78.3: Hyperchylomicronemia
- E78.4: Other hyperlipidemia
- E78.41: Elevated Lipoprotein(a)
- E78.49: Other hyperlipidemia
- E78.5: Hyperlipidemia, unspecified
- E78.6: Lipoprotein deficiency
- E78.7: Disorders of bile acid and cholesterol metabolism
- E78.8: Other disorders of lipoprotein metabolism
- E78.9: Hyperlipidemia, unspecified
What are the coding guidelines for Hyperlipidemia
The selection of the appropriate ICD-10 code should be based on the documentation provided by the healthcare provider. The ICD-10 code should reflect the highest level of specificity available. Accurate coding requires detailed medical records, laboratory results, and clinical assessment. Here are some guidelines for coding hyperlipidemia:
Thoroughly review of medical documentation: Coding should be based on a careful review of the medical record, including physician notes, diagnostic reports, laboratory results, and any other relevant documentation. Accurate coding relies on having comprehensive and specific documentation regarding the type of hyperlipidemia, lipid levels, associated conditions, and any complications or comorbidities.
Adhere to code conventions and guidelines: Correct coding requires following ICD-10 guidelines on the use of combination codes, code sequencing rules, and any special instructions or notes provided for specific codes or conditions.
Code to the highest level of specificity: Select the most specific code that accurately reflects the patient’s condition. The documentation should be examined for details such as the type of hyperlipidemia (e.g., pure hypercholesterolemia, mixed hyperlipidemia), associated conditions (e.g., atherosclerosis), and any related complications or manifestations. Avoid using unspecified codes unless there is no other suitable option.
Consider underlying causes and associated conditions: Hyperlipidemia can be primary (genetic) or secondary to other factors such as lifestyle, medications, or underlying medical conditions. Also, hyperlipidemia often coexists with other conditions such as hypertension, diabetes, or cardiovascular disease. Assign additional codes to capture these comorbidities or complications, as appropriate. Follow the coding guidelines for sequencing and prioritizing the primary and secondary diagnoses.

Diagnosis codes for high Cholesterol
The ICD-10 code E78.00 stands for Pure hypercholesterolemia, unspecified. It is a medical code used to identify and classify cases of high cholesterol in which the levels of LDL (low-density lipoprotein) cholesterol are elevated without a significant increase in triglyceride levels. LDL cholesterol is often referred to as “bad” cholesterol because it can accumulate in the arteries and contribute to plaque formation, a major risk factor for heart disease and stroke.
Final Thoughts
Hyperlipidemia, often asymptomatic, remains a significant concern due to its potential impact on cardiovascular health. Accurate diagnosis is crucial, and understanding the specific types of hyperlipidemia and their associated ICD-10 codes is essential for effective management. Distinguishing between hyperlipidemia and dyslipidemia sheds light on the subtleties in lipid level abnormalities, emphasizing the need for precise diagnosis to guide appropriate treatment.
