CPT® Code 0758T

Add-On Code

Digitization of glass microscope slides for special stain, including interpretation and report, histochemical stain on frozen tissue block (List separately in addition to code for primary procedure)

The CPT® Code 0758T refers to the process of digitizing glass microscope slides that have undergone special staining, which includes the interpretation and reporting of the findings. This procedure is particularly relevant in the context of histochemical stains applied to frozen tissue blocks. The digitization process involves scanning the glass slides into a digital format, allowing the captured images to be stored either on a local computer server or within a cloud-based archive. This digital transformation facilitates further examination by remote pathologists or the use of computer algorithms to assist in providing a pathologic diagnosis. The information obtained from these digital images can be managed and interpreted within an increasingly sophisticated image-based environment. It is important to note that the digitization of slides is performed after the special stains have been applied to the frozen tissue blocks. Common examples of histochemical special stains that may be utilized include oil red O stain, periodic acid Schiff, and Alcian Blue. The code 0758T should be reported separately in addition to the code for the primary procedure when the digitization of the slides is performed concurrently with the histochemical staining, ensuring that the interpretation and report generated from the digital images are clearly distinguished from traditional direct visualization methods using a microscope.
