CPT® Code 0855T

Add-On Code

Digitization of glass microscope slides for bone marrow, smear interpretation (List separately in addition to code for primary procedure)

The CPT® Code 0855T refers to the process of digitizing glass microscope slides specifically for the interpretation of bone marrow smears. This procedure involves scanning glass slides that contain samples of bone marrow, which may include aspirates, cores, or clots. The digitization process transforms these physical slides into digital images that can be stored on a local computer server or in a cloud-based archive. This digital format facilitates further examination by pathologists who may be located remotely, allowing for enhanced diagnostic capabilities. Additionally, the use of computer algorithms can assist in providing pathologic diagnoses, offering an alternative to traditional direct visualization through a microscope. The preparation of a glass slide involves applying a thin smear of the bone marrow sample, which is then fixed in place using a special stain to preserve the cellular details for accurate analysis. It is important to report CPT® Code 0855T separately in conjunction with the primary procedure code when additional slide digitization is performed during the same session.
