CPT® Code 0843T

Add-On Code

Digitization of glass microscope slides for pathology consultation during surgery; cytologic examination (eg, touch preparation, squash preparation), initial site (List separately in addition to code for primary procedure)

The CPT® Code 0843T refers to the process of digitizing glass microscope slides specifically for pathology consultation during surgical procedures. This involves converting traditional glass slides into a digital format, allowing for the captured images to be stored either on a local computer server or within a cloud-based archive. The digitization process is significant as it facilitates further examination by remote pathologists or through the use of computer algorithms, which can assist in providing a pathologic diagnosis that differs from the direct visualization typically achieved through a microscope. This method enhances the ability to manage and interpret the information within an increasingly image-based medical environment. During surgery, intraoperative cytologic examinations, such as touch preparations or squash preparations, are conducted, and the digitization of the glass microscope slides occurs simultaneously. It is important to report CPT® Code 0843T for the initial site of digitization, while CPT® Code 0844T should be used for each additional site that undergoes the same process.
