Decision Criteria

clinical Criteria

  • LDL-C ≥190 mg/dL and family history

coding Criteria

  • Avoid E78.2 if only LDL is elevated

Applicable To

  • Fredrickson Type IIa Hyperlipoproteinemia

Excludes

  • Mixed hyperlipidemia (E78.2)

Clinical Validation Requirements

  • LDL-C ≥190 mg/dL in adults
  • Family history of hypercholesterolemia
  • Genetic testing confirming LDLR, APOB, or PCSK9 mutations

Code-Specific Risks

  • Misclassification with mixed hyperlipidemia

Coding Notes

  • Ensure documentation specifies Fredrickson type and LDL levels.

Ancillary Codes

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

Atherosclerosis of native arteries of right leg with ulceration

I70.241
Use if atherosclerosis affects the right iliac artery.

Atherosclerosis of native arteries of left leg with ulceration

I70.242
Use if atherosclerosis affects the left iliac artery.

Differential Codes

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

Mixed hyperlipidemia

E78.2
Use E78.2 if both LDL and triglycerides are elevated.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Fredrickson Type IIa Hyperlipoproteinemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E78.01.

Impact

Clinical: Incomplete clinical picture, Regulatory: Potential audit flags, Financial: Missed reimbursement opportunities

Mitigation Strategy

Link lipid disorder to vascular complications in notes, Use structured templates

Impact

Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use E78.01 when only LDL is elevated.

Impact

Inaccurate LDL-C documentation can lead to coding errors.

Mitigation Strategy

Ensure direct LDL measurements are used.

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.

Cardiology Progress Note

Specialty: Cardiology

Required Elements

  • LDL-C levels
  • Family history
  • Imaging results
  • Symptoms

Example Documentation

Assessment: 1. Fredrickson type IIa hyperlipoproteinemia (E78.01) - LDL-C: 215 mg/dL. 2. Atherosclerosis of native right internal iliac artery (I70.241) - Imaging: CTA shows 80% stenosis.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Elevated cholesterol
Good Documentation Example
Fredrickson type IIa hyperlipoproteinemia (LDL-C 245 mg/dL) with bilateral iliac artery atherosclerosis per CT angiography
Explanation
The good example provides specific LDL levels and confirms artery involvement.
