Hyperlipidemia is a common medical condition characterized by elevated levels of lipids—such as cholesterol and triglycerides—in the blood. In the ICD-10 classification, hyperlipidemia falls under the “E” category, which includes endocrine, nutritional, and metabolic diseases. There are specific ICD-10 codes for hyperlipidemia covering multiple types and subtypes. Selecting the correct hyperlipidemia diagnosis codes requires a clear understanding of the condition and its clinical classification.
Due to the complexity of medical coding for hyperlipidemia, many physicians rely on professional medical coding and billing services to ensure accurate and compliant reporting. Outsourcing companies that specialize in billing and coding for lipid disorders employ AI solutions along with review by certified coding professionals to assign the appropriate lipid disorder ICD-10 codes based on the medical documentation.

ICD-10 Codes for Hyperlipidemia – Cheat Sheet
The appropriate cholesterol ICD-10 codes depend on the type and severity of the lipid abnormality documented. Below is an ICD-10 coding cheat sheet for hyperlipidemia, updated to reflect current coding standards.
| ICD-10 Code | Description | Notes |
|---|---|---|
| E78.0 | Pure hypercholesterolemia | Elevated cholesterol without significant triglyceride increase |
| E78.00 | Pure hypercholesterolemia, unspecified | Use when documentation confirms hypercholesterolemia but does not specify type |
| E78.01 | Familial hypercholesterolemia | Genetic/familial high cholesterol |
| E78.1 | Pure hyperglyceridemia | Elevated triglycerides without significant cholesterol increase |
| E78.2 | Mixed hyperlipidemia | Both cholesterol and triglycerides elevated |
| E78.3 | Hyperchylomicronemia | Very high triglycerides due to lipoprotein lipase or related enzyme deficiencies |
| E78.41 | Elevated Lipoprotein(a) | Use for lab-confirmed elevated lipoprotein(a) [Lp(a)] |
| E78.49 | Other hyperlipidemia | Specific hyperlipidemia types not classified elsewhere |
| E78.4 | Other hyperlipidemia | Category code that includes E78.41 and E78.49; do not use when a more specific subcode applies |
| E78.5 | Hyperlipidemia, unspecified | Preferred unspecified code when the type of hyperlipidemia is not documented |
| E78.6 | Lipoprotein deficiency | Inherited or acquired lipoprotein deficiency disorders (not routine low HDL or LDL) |
| E78.7 | Disorders of bile acid and cholesterol metabolism | Abnormalities in bile acid or cholesterol metabolism |
| E78.8 | Other specified hyperlipidemia | Documented hyperlipidemia types not classified elsewhere |
| E78.9 | Hyperlipidemia, unspecified | Use only when no further classification is possible |
How to Choose the Correct ICD-10 Code for Hyperlipidemia
The selection of the appropriate ICD-10 code for hyperlipidemia should always be based on thorough provider documentation and reflect the highest level of specificity available. Accurate medical coding for hyperlipidemia requires complete medical records, laboratory results, and clinical assessments. The following guidelines should be considered when coding hyperlipidemia:
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.
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.
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.
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.
Accurate coding is crucial for proper reimbursement, statistical analysis, and effective communication among healthcare providers. AI-powered medical coding services enhance this process by automatically identifying and applying correct ICD-10 codes for hyperlipidemia, based on the detailed clinical documentation. These advanced systems not only minimize the risk of human error but also keep up with the latest updates in coding guidelines, ensuring that the codes applied for hyperlipidemia are always accurate and current.
