Key Information: ICD-10 code for mixed hyperlipidemia

Essential facts and insights about Mixed Hyperlipidemia

The ICD-10 code for mixed hyperlipidemia is E78.2, used when both cholesterol and triglycerides are elevated.

Primary ICD-10-CM Code for mixed hyperlipidemia

Mixed hyperlipidemia
Billable Code

Decision Criteria

clinical Criteria

  • Both LDL-C and triglycerides must be elevated.

documentation Criteria

  • Lab results must be documented.

Applicable To

  • Elevated cholesterol and triglycerides

Excludes

  • Isolated hypercholesterolemia (E78.00)
  • Isolated hypertriglyceridemia (E78.1)

Clinical Validation Requirements

  • Fasting LDL-C ≥160 mg/dL
  • Fasting triglycerides ≥200 mg/dL
  • Two fasting lipid panels ≥2 weeks apart

Code-Specific Risks

  • Incorrect use if only one lipid is elevated
  • Potential audit if lab results are not documented

Coding Notes

  • Ensure lab results are documented to support the diagnosis of mixed hyperlipidemia.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Type 2 diabetes mellitus with other specified complication

E11.69
Use when mixed hyperlipidemia is present with diabetes.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Pure hypercholesterolemia

E78.00
Use when only cholesterol is elevated.

Pure hypertriglyceridemia

E78.1
Use when only triglycerides are elevated.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Mixed Hyperlipidemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E78.2.

Impact

Clinical: Leads to inadequate treatment plans., Regulatory: Fails to meet coding specificity requirements., Financial: May result in lower reimbursement rates.

Mitigation Strategy

Ensure lab results are reviewed before coding., Use specific codes based on lab findings.

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records.

Mitigation Strategy

Use E78.00 for isolated cholesterol elevation and E78.1 for isolated triglyceride elevation.

Impact

Failure to document lab results can lead to audits.

Mitigation Strategy

Always include lab results in the patient's medical record.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Primary Care Progress Note

Specialty: Primary Care

Required Elements

  • Assessment of lipid levels
  • Family history
  • Current medications

Example Documentation

**Assessment:** 42M with familial combined hyperlipidemia (E78.2) - Fasting lipids: LDL-C 185 mg/dL, triglycerides 320 mg/dL - No secondary causes: TSH 2.1 mIU/L, HbA1c 5.7%, creatinine 0.9 mg/dL - FHx: Father MI at age 48 - Treatment: Rosuvastatin 20 mg daily, omega-3 acids 2g BID **Plan:** Repeat lipids in 8 weeks - Counseled on Mediterranean diet (ICD-10 Z71.3)

Examples: Poor vs. Good Documentation

Poor Documentation Example
"Elevated lipids"
Good Documentation Example
"Mixed hyperlipidemia: LDL-C 190 mg/dL, triglycerides 280 mg/dL on 2 consecutive fasts"
Explanation
The good example provides specific lab values and confirms the diagnosis with repeated tests.
