ICD-10 Code for Increased LDL Cholesterol
The ICD-10-CM code for increased LDL cholesterol is E78.00 (Pure hypercholesterolemia, unspecified) or E78.01 (Familial hypercholesterolemia) if the condition is hereditary.
Understanding the Coding Context
While the provided evidence does not contain a specific ICD-10 coding reference document, the clinical guidelines consistently reference elevated LDL cholesterol as a form of hypercholesterolemia, which falls under the E78 category in ICD-10-CM coding.
Key Coding Considerations:
For general elevated LDL cholesterol:
- Use E78.00 (Pure hypercholesterolemia, unspecified) when documenting isolated elevated LDL cholesterol without a specific genetic diagnosis
For familial hypercholesterolemia:
- Use E78.01 (Familial hypercholesterolemia) when genetic testing confirms FH or clinical criteria are met 1, 2
- Sweden specifically introduced E78.0A for familial hypercholesterolemia to improve identification and treatment 2
Important Clinical Thresholds Referenced in Guidelines:
The evidence highlights that LDL-C levels requiring documentation vary by risk category 3:
- LDL-C ≥130 mg/dL is considered elevated for low-risk individuals
- LDL-C ≥100 mg/dL warrants treatment consideration in moderate-risk patients
- LDL-C ≥190 mg/dL suggests possible familial hypercholesterolemia 1, 4
Common Pitfall to Avoid:
The evidence specifically notes that in the United States, there is no dedicated ICD-10 code for elevated lipoprotein(a) levels, requiring clinicians to use a generic hypercholesterolemia code 5. This same limitation may apply to other specific lipid abnormalities, making E78.00 the appropriate default code for documented elevated LDL cholesterol.
For mixed dyslipidemia (elevated LDL-C with other lipid abnormalities), consider E78.2 (Mixed hyperlipidemia) instead.
