Summary & Overview
CPT 0755T: Slide Digitization for Level VI Surgical Pathology
CPT code 0755T is an add-on code for clinical staff work that scans and digitizes glass microscope slides prepared for a Level VI surgical pathology exam (88309). Nationally, this code reflects the growing integration of digital pathology workflows that support remote review, diagnostic archiving, and potential AI-assisted interpretation. Use of the code signals resource allocation for slide scanning rather than primary pathology interpretation.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The summary addresses payer coverage practices, coding benchmarks, and clinical context for implementation across hospital and independent pathology laboratory settings.
Readers will learn what the code represents, the typical clinical settings and service type, and where the code fits within surgical pathology workflows. The publication provides benchmarks and policy considerations relevant to reimbursement, documentation requirements, and operational implications for digitizing Level VI surgical pathology slides.

Billing Code Overview
CPT code 0755T describes clinical staff work to scan and digitize images from glass microscope slides for immediate or later pathologic diagnosis. This add-on code applies specifically to digitization of slides prepared for a Level VI surgical pathology examination (88309).
-
Service type: Slide digitization and image capture performed by clinical staff to create digital pathology images for diagnostic review.
-
Typical site of service: Hospital pathology laboratories, independent pathology labs, and hospital-based surgical pathology suites where Level VI surgical pathology (
88309) is performed.

Clinical & Coding Specifications
Clinical Context
A pathology laboratory receives surgical specimens processed for a Level VI surgical pathology examination (88309) from an operating room where a complex resection was performed for a suspected malignancy. A histotechnologist prepares glass slides stained with hematoxylin and eosin and any special stains requested by the pathologist. Clinical staff then perform slide scanning and digitization using a whole-slide imaging scanner so the pathologist can perform immediate or subsequent digital review for intraoperative consultation, final diagnosis, or remote subspecialty consultation. Typical workflow: slides are accessioned and labeled, the scanner technician verifies slide quality and scans slides to create high-resolution digital images, images are uploaded to the laboratory information system and linked to the 88309 case, and the pathologist reviews images on a digital workstation to render a Level VI surgical pathology interpretation. This service is commonly performed in hospital-based pathology labs or independent diagnostic laboratories serving surgical suites, with patients ranging from adults undergoing complex oncologic resections to smaller specimens requiring subspecialty review.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the digitization required substantially greater technician time or complexity than typical (document rationale). |
52 | Reduced services | Use when only partial slide digitization is performed relative to the full service. |
53 | Discontinued procedure | Use when scanning is started but must be terminated for patient- or equipment-related reasons. |
55 | Postoperative management only | Not typically applicable to technical digitization but may be used when another provider assumes care after initial processing. |
80 | Assistant surgeon | Not applicable to scanning staff; included in payer edits when surgical assistance is reported on related operative services. |
26 | Professional component | Use when reporting only the pathologist’s diagnostic interpretation separate from the technical scanning (if applicable). |
TC | Technical component | Use when reporting only the technical scanning/digitization performed by the laboratory staff. |
59 | Distinct procedural service | Use if scan/digitization is a distinct service separate from other pathology technical services on the same day. |
QK | Medical direction of two, three, or four concurrent anesthesia procedures | Not directly applicable to scanning but sometimes appears in bundled service reviews (rare). |
RT | Right side | Use only when laterality modifiers are required by payers for associated surgical services (not typically used for slide digitization). |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207ZP0102X | Pathology | Anatomic and clinical pathologists interpret digitized slides and integrate findings into 88309 reports. |
| 173E00000X | Histology Technician | Histotechnologists/technicians perform slide preparation and scanning/digitization. |
| 2080P0207X | Laboratory Director | Laboratory medical directors oversee quality assurance for digital pathology workflows. |
| 207L00000X | Surgical Pathology | Surgical pathologists perform Level VI examinations and correlate digital images with gross findings. |
