CPT® Code 0844T

Add-On Code

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

The CPT® Code 0844T 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 facilitates further examination by enabling remote pathologists to analyze the slides or by utilizing computer algorithms that assist in providing a pathologic diagnosis, which is distinct 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 and CPT® Code 0844T for each additional site that is digitized.
