CPT coding for microbiology and virology procedures often cannot be determined before the culture is performed. If a virus other than those specified for this virus-specific culture are recovered, identification will be made, and an additional charge will apply. The client will not be telephoned to approve this charge.

Special Instructions

If reflex testing is performed, concomitant CPT codes/charges will apply.
