CPT code 0115U denotes a Proprietary Laboratory Analyses (PLA) test for the ePlex® Respiratory Pathogen (RP) Panel from GenMark Diagnostics, an automated multiplex nucleic acid assay that identifies 20 common respiratory pathogens from nasopharyngeal specimens. As a PLA code, 0115U is specific to one manufacturer’s assay and is used to report that unique test across billing systems. Nationally, molecular respiratory panels like this are important for pathogen identification, infection control, and clinical decision-making, particularly during respiratory virus seasons and outbreaks.

Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical purpose and service setting for 0115U, plus an outline of common coverage considerations and benchmarks where available. The publication summarizes payer coverage patterns, coding guidance for laboratory reporting, and clinical context for use of multiplex respiratory testing. Data not available in the input is noted where applicable, such as payer-specific reimbursement rates, associated taxonomies, and ICD-10 diagnosis mappings.
