CPT code 84154 represents a laboratory test that measures free prostate specific antigen (free PSA) in serum. Free PSA testing plays a role in the clinical assessment of prostate conditions and can inform diagnostic considerations alongside total PSA and other clinical data. As a standardized CPT laboratory code, 84154 is used across clinical laboratories and hospital outpatient settings and carries national relevance for screening and diagnostic workflows in men's health.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for free PSA testing, common service settings, and the aspects of billing and claims processing that typically affect laboratory services. The publication examines benchmarks and payer policy landscapes where available, summarizes coding and billing considerations, and highlights areas where readers may need to consult payer-specific policies for coverage criteria and reimbursement details.

Data not available in the input for some elements such as associated taxonomies, specific ICD-10 diagnoses, and related procedure codes is noted where applicable. The focus is national in scope and intended to support billing staff, laboratory managers, and policy analysts seeking a clear summary of the clinical and administrative role of CPT code 84154.
