CPT® Code 0846T

Add-On Code

1. Indications

The procedure associated with CPT® Code 0846T is indicated for the digitization of glass microscope slides in the context of immunofluorescence staining. This procedure is typically performed when there is a need to analyze tissue specimens, such as skin biopsies, using immunofluorescence techniques. The indications for this procedure may include, but are not limited to, the following:

• Skin Biopsy Analysis The digitization is performed to facilitate the examination of skin biopsy specimens that require immunofluorescence staining for diagnostic purposes.
• Remote Pathology Consultation The procedure allows for remote pathologists to review and interpret the digitized images, enhancing diagnostic accuracy and collaboration.
• Utilization of Computer Algorithms The digitized slides can be analyzed using advanced computer algorithms to assist in the pathologic diagnosis, providing a modern approach to pathology.

2. Procedure

The procedure for CPT® Code 0846T involves several key steps that ensure the effective digitization of glass microscope slides for immunofluorescence. Each step is crucial for achieving high-quality digital images that can be utilized for further analysis.

• Step 1: Preparation of Specimen The process begins with the preparation of the tissue specimen, such as a skin biopsy, which is subjected to an immunofluorescence antibody stain procedure. This staining is essential for highlighting specific antigens within the tissue.
• Step 2: Slide Creation Once the specimen is stained, it is mounted onto a glass microscope slide. This slide serves as the medium through which the immunofluorescence can be visualized and subsequently digitized.
• Step 3: Digitization Process The glass microscope slide is then scanned using a specialized digital imaging system. This system captures high-resolution images of the stained slide, converting them into a digital format that can be stored and analyzed.
• Step 4: Data Storage The digitized images are stored on a local computer server or within a cloud-based archive. This storage solution allows for easy access and management of the images for future reference and analysis.
• Step 5: Reporting For billing purposes, it is important to report CPT® Code 0845T for the first initial single antibody stain and CPT® Code 0846T for each additional single antibody stain digitization performed, ensuring accurate coding and reimbursement.

3. Post-Procedure

After the digitization procedure is completed, the healthcare provider may need to ensure that the digital images are properly stored and accessible for future analysis. The expected recovery from the procedure itself is minimal, as it primarily involves the technical process of scanning slides rather than any invasive intervention. Additionally, pathologists or other healthcare professionals may review the digitized images remotely, allowing for timely diagnoses and consultations. It is also important to maintain the integrity and security of the digital data, ensuring compliance with relevant regulations regarding patient information and data management.
