Dyslipidemia ICD-10: Complete Coding & Billing Guide

Proper coding of dyslipidemia, which is a condition that leads to abnormal lipid levels in blood, is essential in healthcare in diagnosis coding and the effective subsequent billing and reimbursement. Dyslipidemia is strongly linked with cardiovascular disease, stroke, and diabetes mellitus; hence, it is very critical that healthcare practitioners effectively report this disorder.

This comprehensive guide will discuss the ICD-10 code for dyslipidemia and its variations, including coding for unspecified dyslipidemia, mixed dyslipidemia, and diabetes-related dyslipidemia.

What is Dyslipidemia? (Clinical & Billing Perspective)

Dyslipidemia refers to abnormal levels of lipids (fats) in the blood, including cholesterol and triglycerides. These imbalances may involve:

• High LDL cholesterol (“bad cholesterol”)
• Low HDL cholesterol (“good cholesterol”)
• High triglycerides
• Mixed dyslipidemia (multiple lipid abnormalities)

In medical terms, dyslipidemia is a risk factor for atherosclerosis, heart attack and stroke. When coders and billing teams utilize the right dyslipidemia ICD-10 code, providers will receive the appropriate reimbursement and will not have to wait too long before claims are processed.

Primary Coding Reference: Dyslipidemia ICD-10 Code (E78.5)

The official ICD-10-CM code for dyslipidemia is:

• E78.5 – Dyslipidemia, unspecified

This code is widely used when the provider documents “dyslipidemia” without additional details. It covers cases where lipid abnormalities are present, but the exact type (cholesterol vs triglycerides) is not specified.

Coding for Unspecified Dyslipidemia (E78.5)

When there is no detailed description in the medical documentation, coders must assign the ICD-10 code for dyslipidemia unspecified (E78.5).

Examples include:

• Provider notes “dyslipidemia” with no lab details.
• Clinical documentation lacks specifics on cholesterol or triglyceride levels.

Relevant keywords:

• icd 10 code for dyslipidemia unspecified
• ICD-10 dyslipidemia unspecified

While this code is commonly used, providers should be encouraged to document more detail whenever possible. More specific coding supports better reimbursement and accurate risk adjustment.

Coding for Mixed Dyslipidemia (E78.2)

When a patient has multiple lipid abnormalities, such as high cholesterol and high triglycerides, the correct ICD-10 entry is:

• E78.2 – Mixed hyperlipidemia

This is the official mixed dyslipidemia ICD-10 code.

Accurate documentation of mixed dyslipidemia is especially important in:

• Cardiology practices where lipid disorders are often linked to cardiovascular disease
• Endocrinology clinics for patients with metabolic syndrome or diabetes
• Primary care for preventive health and chronic care management

Coding E78.2 instead of E78.5 reflects the true complexity of the condition and may influence payer risk adjustment models.

Other Dyslipidemia ICD-10 Codes

To avoid denials, coders should know the full range of dyslipidemia ICD-10 codes beyond E78.5 and E78.2:

Note: Using E78.0, E78.1, E78.71, and E78.72 ensures coding precision, reduces denials, and strengthens documentation for payer review.

Dyslipidemia with Type 2 Diabetes Mellitus

Dyslipidemia frequently occurs as a complication of Type 2 diabetes mellitus. In such cases, coders must use both a diabetes code and a dyslipidemia code.

• E11.69: Type 2 diabetes mellitus with other specified complication
• E78.x: Dyslipidemia ICD-10 code (such as E78.5 or E78.2)

Example:

If a provider documents “Type 2 diabetes with dyslipidemia,” coders should report E11.69 + E78.5.

This dual coding is critical for:

• Hierarchical Condition Category (HCC) coding
• Risk adjustment for Medicare Advantage and ACOs
• Accurate payer reimbursement

Why Accurate Dyslipidemia ICD-10 Coding Matters in Medical Billing

The Importance of Accurate Dyslipidemia ICD-10 Coding in Medical Billing: Ensuring proper coding not only supports accurate claim submission and timely reimbursements but also minimises denials, enhances compliance with payer regulations, and improves the overall quality of patient care documentation. Here are some of the uses:

• Claim Approval – Payors need particular ICD-10 codes in order to support medical necessity.
• Maximum Reimbursement – Certain codes, such as E78.2 (mixed dyslipidemia ICD-10), can lead to higher payer reimbursement than unspecified codes.
• Compliance – When the wrong code is used, it can lead to audits or compliance.
• Risk Adjustment – Proper dyslipidemia coding promotes the health of populations and payer risk scoring.

Mistakes, like coding the wrong code, omitting a diabetes complication, or excessive use of unspecified dyslipidemia ICD-10 codes, can result in expensive denials.

Role of Credentialing in Dyslipidemia Billing

Even if the correct ICD-10 code is used, claims may still be denied if the provider is not credentialed with the payer. Credentialing ensures providers can bill for services such as:

• Lipid panel testing (CPT 80061)
• Follow-up visits for cholesterol management
• Medications prescribed for dyslipidemia

Credentialing also ensures compliance with Medicare, Medicaid, and commercial insurance requirements, allowing providers to avoid delays in payment. For practices managing chronic conditions like dyslipidemia, proper credentialing is essential for smooth revenue cycle management (RCM).

Without proper payer enrollment, even correctly coded claims (E78.5, E78.2) may face rejection.

Denial Prevention: Documentation & Coding Strategies

To minimize denials, coders and providers should follow these strategies:

• Document specific lipid abnormality (LDL, triglycerides, Lp(a)).
• Avoid overuse of unspecified code E78.5.
• Link E11.69 + E78.x when diabetes contributes to dyslipidemia.
• Match ICD-10 to the correct CPT lipid test.
• Regularly update payer policy requirements for dyslipidemia claims.

Failure to obtain prior authorisation for lipid panels or advanced lipid testing often leads to payer denials. Our prior authorisation services streamline approvals and protect revenue.

Hello MDs provides end-to-end medical billing services and tailored physician billing solutions that maximize claim acceptance for lipid disorder management.

Conclusion

Dyslipidemia ICD-10 coding is more than diagnosis documentation; it directly affects claim approvals, HCC scoring, and audit readiness. Coders and providers must use specific ICD-10 codes (E78.0–E78.72), align with CPT testing, and document clinical links to diabetes when applicable. By improving coding accuracy, healthcare organisations strengthen compliance and optimise reimbursement.
