CPT® Code 87207

Smear, primary source with interpretation; special stain for inclusion bodies or parasites (eg, malaria, coccidia, microsporidia, trypanosomes, herpes viruses)

The CPT® Code 87207 refers to a laboratory procedure that involves the preparation and examination of a smear from a primary source, with a specific focus on identifying inclusion bodies or parasites. This test is crucial for diagnosing various infections caused by parasites or viral agents. The procedure utilizes special staining techniques, such as Giemsa, Giemsa-Wright, or Tzanck stains, to enhance the visibility of these organisms under a microscope. The samples for this test can be derived from multiple bodily fluids and tissues, including blood, stool, urine, sputum, duodenal aspirate, liver or pancreatic aspirate, cerebrospinal fluid (CSF), nasal secretions, corneal or conjunctival scrapings, and biopsy tissue. The examination of blood can reveal the presence of malarial parasites, trypanosomes, and microfilaria, while stool and sputum samples may be tested for microsporidia and various parasitic larvae or ova. Urine samples can be analyzed for schistosoma, and aspirates from liver and lung abscesses may be examined for Entamoeba histolytica. The procedure begins with the collection of blood via a fingerstick, where droplets are placed on slides in both thin and thick layers. Other cell materials are applied in a thin layer using an inoculation hook and are then fixed with heat. After staining, the slides are meticulously examined under a microscope to identify and count any inclusion bodies, ova, or parasites present. A comprehensive written report detailing the findings is subsequently generated, providing essential information for diagnosis and treatment planning.
