CPT code 87511 represents an amplified nucleic acid probe test for Gardnerella vaginalis, a common cause of bacterial vaginosis. The test is used to detect specific nucleic acid targets from vaginal specimens and supports diagnosis of infections that commonly present with abnormal or odorous vaginal discharge. Nationally, molecular diagnostic codes such as 87511 matter because they inform laboratory reimbursement, inform diagnostic pathways for sexually transmitted and vaginal infections, and influence availability of rapid, sensitive testing in outpatient and laboratory settings.

Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of clinical context for the test, expected sites of service, common billing modifiers (listed separately), and how the code fits into laboratory service lines. The publication provides benchmarks and payment considerations where available, summarizes relevant policy updates affecting molecular diagnostic reporting, and outlines the typical clinical scenarios that generate use of 87511.

The report is intended for billing managers, laboratory directors, clinicians ordering testing, and policy analysts seeking a clear, national-level summary of what CPT code 87511 covers, how it is used in clinical practice, and the operational settings where the test is performed. Data not available in the input are noted where applicable.
