CPT 0563U: Biofire Spotfire Respiratory/Sore Throat RT–PCR Panel

CPT code 0563U designates a proprietary laboratory analysis for the Biofire® Spotfire® Respiratory/Sore Throat (R/ST) Panel by bioMérieux, a multiplex RT–PCR assay that detects 11 viruses and four bacteria from an upper respiratory specimen and reports each pathogen as positive or negative. As a PLA code tied to a single manufacturer’s test, 0563U matters nationally for laboratory billing, coding clarity, and payer coverage determinations for multiplex respiratory pathogen testing.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a national overview of coverage considerations and benchmarking for proprietary respiratory molecular testing, highlighting how payers approach PLA-coded assays compared with broader multiplex panels.

Readers will find concise clinical context for the assay, the typical sites of service (clinical and hospital laboratories), common billing modifiers where available, and what to expect in payer coverage language. The report summarizes payer coverage patterns, coding and billing implications of PLA designation, and operational considerations for lab services submitting 0563U. Data not provided in the input are noted as unavailable where applicable.

Billing Code Overview

CPT code 0563U is a Proprietary Laboratory Analyses (PLA) code that applies exclusively to the Biofire® Spotfire® Respiratory/Sore Throat (R/ST) Panel — Respiratory Menu from bioMérieux. The test uses reverse transcription polymerase chain reaction (RT–PCR) technology on an upper respiratory specimen to detect 11 viruses and four bacteria. Each pathogen included on the panel is reported as either positive or negative.

Service Type: Proprietary molecular diagnostic laboratory test (RT–PCR panel for respiratory pathogens)

Typical Site of Service: Clinical laboratory or hospital laboratory

Clinical Context

A patient presents to an outpatient clinic or urgent care center with acute upper respiratory symptoms such as fever, sore throat, cough, nasal congestion, and/or shortness of breath during respiratory virus season. The clinician performs a focused history and physical exam and obtains an upper respiratory specimen (e.g., nasopharyngeal swab or nasal swab) for molecular testing. The specimen is sent to the performing laboratory using the Biofire® Spotfire® Respiratory/Sore Throat (R/ST) Panel — Respiratory Menu from bioMérieux. The laboratory runs reverse transcription polymerase chain reaction (RT–PCR)–based testing that reports each of 11 viruses and four bacteria as positive or negative. Results are returned to the ordering clinician to guide patient counseling, antiviral or antibiotic decision-making, isolation and infection-control measures, and public health reporting as required. Typical sites of service include hospital laboratories, outpatient/ambulatory care clinics, urgent care centers, and independent commercial reference laboratories.
