CPT® Code 84702 is used to report quantitative measurement of human chorionic gonadotropin (hCG) in blood. This test provides an exact hCG level, making it essential for confirming and monitoring pregnancy, as well as evaluating certain medical conditions such as ectopic pregnancy or trophoblastic disease.
This code represents the laboratory assay only, not specimen collection or interpretation services, which may be reported separately when appropriate.

- Evaluation of suspected ectopic pregnancy
- Assessment of miscarriage or pregnancy complications
- Monitoring gestational trophoblastic disease
When to Use CPT® 84702
CPT 84702 is appropriate when:
- Measuring quantitative hCG levels to confirm or monitor pregnancy
- Tracking hCG trends over time for clinical decision-making
- Evaluating symptoms such as pelvic pain or abnormal bleeding
- Monitoring treatment or resolution of pregnancy-related conditions
Examples:
- Confirming pregnancy with a serum quantitative hCG test
- Serial hCG testing to assess viability of early pregnancy
- Evaluating suspected ectopic pregnancy with rising or abnormal hCG levels
- Monitoring declining hCG levels after miscarriage
Documentation Requirements
To support CPT 84702 billing, documentation should include:
- Patient identifiers and date of service
- Clinical indication for testing
- Specimen type (e.g., serum, plasma)
- Test performed (quantitative hCG)
- Test result and date reported
- Ordering provider information
Clear documentation supports medical necessity, accurate billing, and continuity of care.
Reimbursement and Coding Considerations
- CPT 84702 is generally covered when medically necessary
- Distinguish from qualitative hCG tests (e.g., 84703)
- Diagnosis coding should support pregnancy-related or gynecologic indications
- Often performed as serial testing, which may be subject to payer frequency guidelines
- Specimen collection may be billed separately if allowed
Always verify payer-specific laboratory billing requirements.
