CPT® Code 0762T

Add-On Code

Digitization of glass microscope slides for immunohistochemistry or immunocytochemistry, per specimen, each multiplex antibody stain procedure (List separately in addition to code for primary procedure)

Digitization of glass microscope slides refers to the process of converting physical glass slides into a digital format. This procedure is specifically utilized for immunohistochemistry or immunocytochemistry, which are techniques used to identify specific antigens in tissue samples or cultured cells. The digitization process involves scanning the glass slides, capturing high-resolution images that are then stored either on a local computer server or in a cloud-based archive. This digital transformation facilitates further examination of the slides, allowing pathologists to analyze the images remotely or utilize computer algorithms for diagnostic purposes. The information obtained from these digital images can be managed and interpreted within an increasingly image-based medical environment. The procedure is particularly relevant when special stain slides are prepared, as these slides are scanned into a digital slide imaging system. The antibody stains used in immunohistochemistry or immunocytochemistry are essential for detecting specific markers that are indicative of various types of cancers, particularly those where certain tumor antigens are expressed. For instance, the digitization process can be reported using CPT® Code 0762T when it is performed concurrently with a multiplex antibody stain procedure, such as an AMACR/P504S or a P63/HMWCK/AMACR cocktail stain for prostate cancer. This allows for a comprehensive pathological diagnosis, with the interpretation and report being distinct from traditional direct visualization methods through a microscope.
