CPT® Code 83695 is used to report laboratory testing that measures Lipoprotein (a), also known as Lp(a), in the blood. Lp(a) is a genetically determined lipid particle associated with an increased risk of cardiovascular disease, including coronary artery disease, stroke, and atherosclerosis. This test helps providers assess inherited cardiovascular risk and guide preventive care and treatment planning.
Lp(a) testing is especially useful for patients with a personal or family history of premature cardiovascular disease.
Key Facts About CPT® 83695
Service type: Laboratory lipid test
Provider type: Physicians and qualified healthcare professionals who order laboratory testing
Medical services included: Yes—quantitative measurement of Lipoprotein (a) in blood
Specimen type: Serum or plasma
Test method: Quantitative immunoassay or equivalent laboratory method
Common clinical indications:
- Assessment of inherited cardiovascular disease risk
- Family history of premature heart disease or stroke
- Evaluation of unexplained cardiovascular events
- Risk stratification in patients with borderline or elevated cholesterol levels
- Monitoring patients with known cardiovascular disease risk factors
When to Use CPT® 83695
CPT 83695 is appropriate when:
- Lipoprotein (a) testing is ordered to evaluate cardiovascular risk
- The test is medically necessary based on patient history, symptoms, or risk factors
- Results are used to guide preventive care, treatment, or risk management
- The test is performed on a properly collected blood specimen
Examples:
- Testing a patient with family history of early heart disease for inherited risk factors
- Evaluating cardiovascular risk in a patient with normal cholesterol but unexplained cardiac events
- Assessing additional risk factors in patients with metabolic or cardiovascular conditions
- Screening patients with premature coronary artery disease
Documentation Requirements
To support CPT 83695 billing, documentation should include:
- Patient identifiers and date of service
- Provider order for Lipoprotein (a) testing
- Clinical indication or medical necessity
- Specimen type and collection date
- Test results and reference ranges
- Ordering provider credentials and signature
- Laboratory performing the test
Complete documentation supports proper coding, reimbursement, and clinical decision-making.
Reimbursement and Coding Considerations
- CPT 83695 is reimbursed when medically necessary and properly documented
- Coverage varies depending on payer policies and cardiovascular risk indications
- Lipoprotein (a) testing is often used alongside standard lipid panels
- Each Lipoprotein (a) test performed is billed as a separate laboratory service
- Verify payer-specific requirements and medical necessity criteria
Proper coding and documentation help ensure accurate reimbursement and compliance.
