CPT® Code 0851T

Add-On Code

Digitization of glass microscope slides for morphometric analysis, in situ hybridization (quantitative or semiquantitative), manual, per specimen; initial single probe stain procedure (List separately in addition to code for primary procedure)

The CPT® Code 0851T refers to the process of digitizing glass microscope slides specifically for morphometric analysis and in situ hybridization, which can be either quantitative or semi-quantitative. This procedure involves converting traditional glass slides into a digital format, allowing for the captured images to be stored on a local computer server or within a cloud-based archive. The digitization process enhances the ability to examine the slides remotely, enabling pathologists to analyze the images without being physically present. Additionally, computer algorithms can be employed to assist in providing pathologic diagnoses, which offers a significant advantage over direct visualization through a microscope. The morphometric analysis facilitated by this technique utilizes in situ hybridization, a method that employs fluorescent tagging to visualize specific genes or portions of genes within the sample. Typically, samples such as bone marrow or tumor tissues are prepared manually for analysis, and the digitization of these slides occurs concurrently. It is important to note that CPT® Code 0851T is specifically designated for the initial single probe stain procedure, and additional codes are available for subsequent procedures involving additional single probe stains or multiplex probe stains.
