CPT® Code 87206

Smear, primary source with interpretation; fluorescent and/or acid fast stain for bacteria, fungi, parasites, viruses or cell types

The CPT® Code 87206 refers to a laboratory procedure known as a smear, which is performed on a primary source with interpretation. This test utilizes fluorescent and/or acid fast staining techniques to identify various microorganisms, including bacteria, fungi, parasites, viruses, or specific cell types present in body fluids or tissues. The procedure is particularly useful for analyzing samples such as gastric aspirate, urine, vitreous fluid, cerebrospinal fluid (CSF), respiratory secretions, and other body tissues. The acid fast stain technique, which employs auramine O, is specifically designed to color the cells found in sputum or respiratory secretions, aiding in the identification of organisms like mycoplasma and actinomycetes. Additionally, KOH stain and Calcofluor White stain are utilized to detect free-living amoebae in samples from CSF, corneal scrapings, vitreous fluid, and tissue. During the procedure, a drop of the suspended culture or cell material is carefully applied in a thin layer onto a microscope slide using an inoculation hook, followed by heat fixation. The slide is then stained, and a thorough examination is conducted under a microscope to identify and count the microorganisms or cell types present. The findings are documented in a written report, providing essential information for diagnosis and treatment planning.
