CPT® Code 0854T

Add-On Code

1. Indications

The procedure associated with CPT® Code 0854T is indicated for the digitization of glass microscope slides specifically for blood smear analysis. This process is typically performed when there is a need for enhanced examination of blood samples, allowing for remote evaluation by pathologists or the application of computer algorithms to assist in diagnosis. The indications for this procedure may include:

• Remote Pathology Evaluation The need for pathologists to analyze blood smear images from a distance, facilitating consultations and second opinions.
• Enhanced Diagnostic Accuracy Utilizing computer algorithms to improve the accuracy of pathologic diagnoses compared to traditional methods.
• Archiving and Record Keeping The requirement for digital storage of blood smear images for future reference, research, or educational purposes.

2. Procedure

The procedure for digitizing glass microscope slides for blood smear analysis involves several key steps, which are detailed as follows:

• Preparation of the Blood Smear A drop of blood is placed on a clean glass microscope slide. The blood is then spread thinly across the slide to create a uniform layer, which is essential for accurate microscopic examination. This step is critical as it ensures that the cells are adequately separated and can be easily visualized under a microscope.
• Fixation of the Slide After the blood has been spread, the slide is fixed in place using a special stain. This fixation process preserves the cellular morphology and enhances the contrast of the blood cells, making them more distinguishable during the digitization process.
• Digitization of the Slide The prepared glass slide is then scanned using a digital imaging system. This process converts the physical slide into a digital format, capturing high-resolution images of the blood smear. The images are stored on a local computer server or in a cloud-based archive, allowing for easy access and management.
• Interpretation by Physician Once digitized, the images can be interpreted by a physician. The physician reviews the digital images, providing a written report based on their findings. This interpretation may involve identifying abnormalities in the blood cells, which is crucial for diagnosing various hematological conditions.

3. Post-Procedure

After the digitization procedure is completed, the physician will typically provide a written report detailing their findings from the digital images. This report is essential for documenting the results of the analysis and may be used for further clinical decision-making. Additionally, the digital images can be archived for future reference, allowing for ongoing evaluation and comparison as needed. It is important to ensure that the digital storage system is secure and compliant with relevant regulations to protect patient information. Follow-up care or additional testing may be indicated based on the findings reported by the physician.
