Summary & Overview
CPT 0854T: Digital Pathology Slide Scanning for Peripheral Blood Smears
CPT code 0854T is an add-on code for clinical staff work to scan and digitize whole–slide images from glass microscope slides to support immediate or later pathologic diagnosis. As digital pathology expands, this code captures the additional clinical effort required to convert glass slides into whole–slide digital images alongside peripheral blood smear services. The code is reported per unit of digitized slides in conjunction with 85060.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication summarizes national relevance for laboratories and pathology services, outlines typical sites of service (clinical laboratories and hospital pathology departments), and highlights billing considerations tied to this add-on code.
Readers will find a concise explanation of the clinical context for digitizing slides, an overview of payer coverage landscape, and practical benchmarks and policy updates where available. The content clarifies when 0854T is applicable, its relationship to peripheral blood smear processing (85060), and what to expect in claims structure and reporting. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 0854T describes clinical staff work to scan and digitize whole–slide images from glass microscope slides for immediate or later pathologic diagnosis. This add-on code is reported as one unit when digitizing slides associated with one unit of 85060, which covers peripheral blood smear slide preparation and interpretation.
Service type: Digital pathology slide scanning and image digitization performed by clinical staff
Typical site of service: Clinical laboratory, hospital pathology department, or other diagnostic laboratory setting where microscope slides are prepared and digitized
Clinical & Coding Specifications
Clinical Context
A hematology outpatient laboratory receives a physician order for peripheral blood smear evaluation to investigate anemia and suspected hemolysis in a 62-year-old male with fatigue and elevated reticulocyte count. A phlebotomy technician prepares glass blood smear slides. Clinical staff then scan the completed glass slides using a whole-slide image scanner to create high-resolution digital images for pathologist review and potential telepathology consultation. The digitized images are used for the pathologist’s immediate interpretation or archived for later review, enabling remote sign-out and facilitating image sharing for quality assurance or second opinions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the scanning and digitization required substantially greater resources or complexity than typical (document justification). |
52 | Reduced services | Use when only partial digitization was performed relative to the full-service expectation. |
53 | Discontinued procedure | Use if the scanning process was started but terminated due to technical failure or specimen issue; document reason. |
Q1 | Clinical staff performed diagnostic procedures under physician direction (CLIA waived) | Use when clinical staff, not the interpreting pathologist, perform the slide scanning/digitization under appropriate supervision. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207Q00000X | Clinical Laboratory | Laboratory professionals and technologists who perform slide preparation and scanning. |
2080P0006X | Hematology | Hematologists order and interpret peripheral smear results and may oversee digitization workflows. |
2085R0203X | Pathology | Anatomic and clinical pathologists interpret the digital whole-slide images and provide diagnostic reports. |
