Summary & Overview
CPT 0762T: Slide Digitization for Multiplex Immunohistochemistry
CPT code 0762T is an add-on pathology code that reports clinical staff work to scan and digitize glass microscope slides prepared for multiplex immunohistochemistry (88344). The code captures the labor and procedural steps required to convert stained slides into digital images for immediate or deferred pathologic interpretation, supporting telepathology, digital archiving, and remote consultation workflows. Nationally, adoption of digital pathology workflows is increasing, making accurate reporting for slide digitization relevant for clinical operations, quality assurance, and reimbursement consistency.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The coverage and coding expectations from these payers influence how pathology providers bill for add-on digitization services and integrate digital imaging into existing lab workflows.
Readers will find a concise overview of what CPT code 0762T represents, typical places where the service is performed, and the clinical context linking the code to multiplex immunohistochemistry procedures. The publication also summarizes common billing modifiers and payer considerations, benchmarking practices, and policy trends affecting digital pathology reporting and adoption. Data not available in the input is noted where relevant.
Billing Code Overview
CPT code 0762T 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 multiple–antibody (multiplex) immunohistochemistry stain exam (88344).
Service Type: Slide digitization for multiplex immunohistochemistry
Typical Site of Service: Pathology laboratories or hospital-based pathology departments, where glass slides are prepared and scanned for diagnostic review or consultation.
Clinical & Coding Specifications
Clinical Context
A surgical pathology laboratory receives a skin punch biopsy from a patient with a suspected cutaneous lymphoma. The laboratory histotechnologist prepares glass slides with a multiplex immunohistochemistry (IHC) stain panel to evaluate multiple antibodies on a single tissue section. Clinical staff operate a whole‑slide scanner to digitize the multiplex IHC slides so the pathologist can review high‑resolution images on a workstation for immediate or later diagnostic interpretation. The workflow includes accessioning, slide preparation and staining, quality check, scanning and image QC, and electronic transfer to the pathologist. Typical site of service is an independent pathology laboratory, hospital outpatient laboratory, or anatomic pathology department within an acute care hospital.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required to scan and digitize slides is substantially greater than typical due to technical complexity or unusual circumstances. |
51 | Multiple procedures | Use when multiple add‑on or primary procedures are billed together and payor requires indication of multiple procedures. |
