Summary & Overview
CPT 0752T: Slide Digitization for Level III Surgical Pathology
CPT code 0752T is an add-on code that documents clinical staff time to scan and digitize images from glass microscope slides for use in pathologic diagnosis, specifically for slides prepared for a Level III surgical pathology exam (88304). Nationwide, the code reflects growing adoption of digital pathology workflows that enable remote review, image archiving, and integration with digital pathology systems. Its use affects billing practices in hospital and independent pathology labs and has implications for operational workflow, staffing, and capital investment in scanning equipment.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical and billing context for 0752T, typical sites of service, and the role of the code as an add-on to Level III surgical pathology services. The publication summarizes benchmarks where available, notes common modifiers and billing considerations, and highlights policy and coverage dynamics relevant to digital pathology digitization services.

Billing Code Overview
CPT code 0752T describes clinical staff work to scan and digitize images from glass microscope slides for immediate or later pathologic diagnosis. This add-on code specifically applies to digitization of slides prepared for a Level III surgical pathology exam (88304).
Service type: Slide digitization and image scanning performed by clinical staff as part of surgical pathology workflow
Typical site of service: Hospital pathology laboratories, independent pathology laboratories, and outpatient anatomic pathology facilities where surgical pathology specimens are processed and reviewed
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient undergoes a surgical excision for a suspected invasive skin malignancy. Formalin-fixed tissue is processed, embedded, sectioned, and stained onto glass microscope slides for a Level III surgical pathology examination (88304). Clinical staff perform slide scanning and digitization to create high-resolution whole slide images for immediate intra-departmental review and asynchronous pathologic diagnosis. The workflow: accessioning and labeling of slides in the histology lab → verification of slide quality and identifiers by histology staff → loading slides into a digital whole-slide scanner by trained clinical staff → scanning and image stitching, quality control of digital images, and transfer into the pathology image management system or electronic medical record for pathologist review and archival. Typical site of service is an in-hospital pathology laboratory or an independent reference pathology lab with digital pathology capabilities. The patient encounter includes surgical specimen submission by the operating surgeon, histology processing, and additive digital imaging service performed as an adjunct to the Level III surgical pathology exam for diagnostic consultation, telepathology, or archival purposes.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the digitization required substantially greater work or complexity than typical (document justification). |
52 | Reduced services | Use when only a portion of the scanning/digitization service is performed or limited imaging is completed. |
53 | Discontinued procedure | Use when scanning is started but terminated due to technical failure or unacceptable slide quality. |
55 | Separate retrieval of medical records / continuity of care (provider left service) | Use when professional continuity changes affect the imaging workflow; applicable to attributing services among providers. |
80 | Assistant surgeon | Use when a designated assistant performs technical elements related to specimen handling or scanning under supervision, if applicable by payer rules. |
TC | Technical component | Use to indicate the technical component of the service when billing the facility or technical provider separately from the pathologist interpretation. |
XS | Separate structure | Use when the digitization service is performed on slides from a different anatomical site or separate encounter than the primary pathology service. |
26 | Professional component | Use when billing only the professional component (pathologist image review) in conjunction with technical digitization services. |
57 | Decision for surgery | Use when the digitization is directly associated with a new operative procedure decision; document linkage to the surgical event. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207RH0000X | Anatomic/Clinical Pathology | Pathologists who interpret the scanned images and oversee diagnostic workflow. |
174100000X | Diagnostic Radiology (digital imaging oversight) | In some institutions, diagnostic imaging informatics staff coordinate digital imaging infrastructure. |
331K00000X | Histology Technician / Clinical Laboratory Technician | Clinical staff who perform slide preparation and scanning; represented here by laboratory technologist taxonomy. |
335E00000X | Pathology Informatics Specialist | Specialists who manage digital pathology systems, quality control, and image storage workflows. |

Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
88304 | Surgical pathology, gross and microscopic examination; level III — intermediate complexity | Primary pathology examination for which 0752T digitization is an add-on; slides prepared for 88304 are digitized under 0752T for pathologist review. |
88305 | Surgical pathology, gross and microscopic examination; level IV — complex | Higher-level surgical pathology exam often performed on larger or more complex specimens; slides from 88305 may also be digitized (note: 0752T specifically describes digitization for slides prepared for 88304). |
88342 | Immunohistochemistry or immunocytochemistry, per specimen; initial single antibody stain | Ancillary stains performed on slides that may also be digitized for interpretation and documentation alongside routine stains. |
88341 | Immunohistochemistry or immunocytochemistry, per specimen; each additional single antibody stain | Additional ancillary IHC stains that supplement the Level III exam and may be included in the digital image set. |
99070 | Supplies and materials (e.g., scanners, reagents) provided by the laboratory | Captures the cost of consumable supplies and discrete materials used in slide scanning and digitization when applicable and allowed by payer policy. |
