CPT code 87634 represents an amplified nucleic acid probe test for detection of respiratory syncytial virus (RSV) antigen. This molecular diagnostic code covers laboratory-performed amplification and probe-based detection of RSV from patient specimens. The code is used across clinical and hospital laboratory settings and matters nationally because RSV is a common cause of respiratory illness, especially in infants, older adults, and immunocompromised patients, and molecular testing influences diagnosis, cohorting, and infection-control measures.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national-level context about the clinical purpose of the test, typical sites of service, and payer coverage scope. The publication outlines benchmarks for utilization and reimbursement trends where available, summarizes relevant policy updates affecting laboratory molecular diagnostics, and provides clinical context on when amplified nucleic acid probe testing is applied for RSV detection.

What readers will learn: an executive view of the clinical role of CPT code 87634, which providers and sites commonly bill it, which major payers cover the service, and where to look for policy guidance and billing considerations. Data not available in the input is noted where applicable.
