CPT® Code 83704 is used to report advanced lipoprotein testing that measures the number and subclasses of lipoprotein particles in blood. Unlike a standard lipid panel, this test provides deeper insight into cardiovascular risk by evaluating particle concentration and distribution (e.g., LDL-P, HDL subclasses).
This code represents the laboratory analysis only, not specimen collection or interpretation services, which may be reported separately when appropriate.
Key Facts About CPT® 83704
- Service type: Laboratory test (advanced lipid analysis)
- Test: Lipoprotein particle number and subclasses
- Specimen type: Serum or plasma
- Test purpose: Cardiovascular risk assessment and lipid profiling
- Provider type: Laboratories, physicians, and qualified healthcare professionals
Common clinical indications:
- Cardiovascular risk stratification beyond standard lipid panel
- Patients with normal LDL-C but suspected elevated cardiovascular risk
- Metabolic syndrome or insulin resistance
- Monitoring response to lipid-lowering therapy
- Functional and integrative cardiometabolic assessments
When to Use CPT® 83704
CPT 83704 is appropriate when:
- Evaluating lipoprotein particle number and subclasses for advanced risk assessment
- Standard lipid results do not fully explain a patient’s cardiovascular risk
- Monitoring response to lifestyle or pharmacologic lipid interventions
- Assessing patients with complex metabolic or cardiometabolic conditions
Examples:
- Ordering advanced lipid testing for a patient with family history of heart disease despite normal cholesterol
- Monitoring LDL particle number in a patient on statin or lifestyle therapy
- Evaluating cardiometabolic risk in a patient with insulin resistance
- Including lipoprotein subclass analysis in a comprehensive wellness panel
Documentation Requirements
To support CPT 83704 billing, documentation should include:
- Patient identifiers and date of service
- Clinical indication for advanced lipid testing
- Specimen type (e.g., serum, plasma)
- Test performed (lipoprotein particle number and subclasses)
- Test results and date reported
- Ordering provider information
Clear documentation supports medical necessity and appropriate reimbursement for specialized testing.
Reimbursement and Coding Considerations
- CPT 83704 may have variable coverage, as it is considered an advanced or specialized test
- Diagnosis coding should support cardiovascular or metabolic risk evaluation
- Often performed in addition to standard lipid panels (e.g., CPT 80061)
- Some payers may require prior authorization or additional justification
- Frequency of testing may be limited by payer policy
Always verify payer-specific guidelines for advanced lipid testing.
