Summary & Overview
CPT 80055: Obstetric Panel for Prenatal Laboratory Evaluation
CPT code 80055 designates a comprehensive obstetric laboratory panel used in prenatal evaluation. The panel bundles several essential tests—complete blood count with differential, hepatitis B surface antigen, rubella antibody, qualitative non-treponemal syphilis test, red blood cell antibody screen, ABO typing, and Rh typing—integral to assessing maternal and fetal risk early in pregnancy. Nationally, this panel is a standard component of prenatal care and influences clinical management, transfusion planning, and public health screening efforts.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find an overview of how the service is defined clinically, typical sites of service, and the components that constitute the bundled panel. The publication also summarizes payer coverage considerations, coding practice implications, common associated modifiers, and benchmarking context where available. Policy updates relevant to laboratory bundling and prenatal screening are addressed to inform coding accuracy and payer interactions.
This summary provides clinicians, billing professionals, and policy analysts a concise reference to the clinical scope of CPT code 80055, the tests it encompasses, and the payer landscape relevant to national prenatal laboratory services. Data not available in the input is noted where applicable in the full publication.

Clinical & Coding Specifications
Clinical Context
A pregnant patient presents for routine prenatal laboratory evaluation at an outpatient obstetrics clinic or hospital-based prenatal testing laboratory. The clinic nurse draws blood during the initial prenatal visit (typically first trimester) or at a prenatal screening visit. The laboratory performs an obstetric panel that includes a complete blood count with differential for anemia and infection assessment, hepatitis B surface antigen to assess maternal infectivity, rubella IgG antibody to determine immunity status, a qualitative non-treponemal syphilis test for screening (e.g., RPR or VDRL), a red blood cell antibody screen to detect alloimmunization, ABO blood grouping, and Rh (D) typing to determine Rh incompatibility risk. Results are routed to the ordering obstetric provider (OB/GYN, maternal-fetal medicine specialist, or family medicine clinician) for interpretation and incorporation into the prenatal care plan. Typical sites of service are outpatient physician offices, ambulatory clinics, hospital outpatient departments, and clinical reference laboratories. The service type is a prenatal obstetric laboratory panel billed under a single-panel CPT code for bundled testing performed by the laboratory analyst.
