Summary & Overview
CPT 0761T: Digital Slide Scanning for Immunohistochemistry
CPT code 0761T is an add-on billing code that describes clinical staff work to scan and digitize glass microscope slides for immediate or later pathologic diagnosis, specifically for slides prepared for an additional single antibody immunohistochemistry stain (+88341). Nationally, this code captures a growing area of pathology workflow modernization as laboratories adopt digital pathology for diagnostic review, archiving, and remote consultation. The code matters because it isolates the labor and technology steps for slide digitization from other pathology services, enabling clearer reporting of digital pathology activity and resource use.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and site-of-service implications, payer coverage considerations, and benchmarking guidance where available. The publication outlines what the code represents, common clinical settings that use this service, and how the code relates to immunohistochemistry workflow. Data not available in the input where specific payer policies, reimbursement benchmarks, associated taxonomies, ICD-10 pairings, and related codes would normally be discussed.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of atypical melanocytic proliferation undergoes an excisional biopsy of a suspicious skin lesion. The surgical specimen is processed in pathology: glass slides are prepared with hematoxylin and eosin (H&E) and a routine immunohistochemical (IHC) panel. Additional single-antibody IHC staining is ordered to clarify a specific marker. Clinical laboratory staff perform digital scanning of the glass slide prepared for the additional single-antibody IHC stain to produce a high-resolution digital image for pathologist review and archiving. The workflow: specimen accessioning → slide preparation and IHC staining (+88341 for the single antibody stain) → clinical staff perform slide scanning and digitization using a whole-slide scanner → pathologist reviews digital images for final diagnosis and reporting. Typical site of service is an outpatient hospital laboratory or independent clinical pathology laboratory integrated with surgical pathology services.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the slide scanning/digitization requires substantially greater work than typical (rare for routine scans). |
52 | Reduced services | Use when limited scanning is performed compared with full standard digitization. |
53 | Discontinued procedure | Use if scanning was started but aborted for clinical/technical reasons before completion. |
59 | Distinct procedural service | Use when this add-on scanning service is distinct from other procedures performed on the same specimen or same day. |
80 | Assistant surgeon | Not typically applicable to scanning; use only if an assistant (credentialed technologist) is separately reportable under specific payor rules. |
LT | Left side | Use when laterality reporting is required and the specimen is from the left side (applies when laterality is documented). |
Q1 | Qualified nonphysician health care professional | Use when the service is performed by a qualified nonphysician (e.g., histology technologist) and payor requires qualification reporting. |
TC | Technical component | Use when reporting only the technical component of services if professional component is billed separately by the pathologist. |
XU | Unusual non-overlapping service | Use when the scanning service is distinct and does not overlap with other services on the same specimen per Modifier XU guidance. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207P00000X | Anatomic Pathology | Pathologists who interpret digitized slides and sign reports. |
| 207L00000X | Pathology & Laboratory | Laboratory directors overseeing histology and digital pathology processes. |
| 163W00000X | Histology Technician | Technologists performing slide preparation and scanning. |
| 207K00000X | Clinical Pathology | Clinicians involved when ancillary testing and digital images are used for diagnosis. |

Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
88341 | Immunohistochemistry or immunocytochemistry, single antibody stain, per specimen; manual or automated, initial single antibody stain | This add-on scanning code specifically describes digitization of slides prepared for an additional single antibody IHC stain billed as 88341. |
88342 | Immunohistochemistry or immunocytochemistry, each additional single antibody stain | Often performed alongside the initial IHC stain; additional stains may generate more slides requiring digitization. |
88305 | Level IV surgical pathology, gross and microscopic examination | Primary surgical pathology interpretation that may follow H&E and IHC staining; digital images assist pathologist review. |
88331 | Pathology consultation during surgery (frozen section) | While frozen section is separate, digitization workflows may support intraoperative consults in some digital pathology systems. |
88360 | Morphometric analysis (e.g., tumor immunoprofile quantification) | Quantitative image analysis may be performed on digitized IHC slides to assist in diagnostic or prognostic assessments. |
