Summary & Overview
CPT 0894T: Liver Allograft Cannulation for Perfusion Preservation
CPT code 0894T covers the insertion and subsequent removal of a cannula into a liver allograft to support perfusion-based organ preservation. This procedure is a component of modern organ transplantation logistics and matters nationally because ex vivo and machine perfusion techniques can affect organ viability, waitlist outcomes, and transplant program workflows.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the code, the typical site of service, and the types of benchmarks and policy issues commonly assessed for organ preservation procedures. The publication summarizes how CPT code 0894T fits into transplant service lines, highlights common billing considerations, and outlines areas where payers and programs monitor utilization and coverage, including performance benchmarks and prior authorization practices.
This national-level summary is intended to orient clinicians, billing professionals, and policy analysts to the code’s purpose and relevance, and to indicate what additional data and policy updates are typically relevant when evaluating use and coverage of organ perfusion cannulation services.
Billing Code Overview
CPT code 0894T describes insertion and later removal of a thin tube (cannula) into a liver allograft that is expected to be transplanted into a patient. The service involves placing the cannula into the donor organ to enable a perfusion service that helps preserve the liver between procurement and transplantation.

Service type: Organ preservation cannulation and removal

Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves a donor liver allograft prepared at an organ procurement organization or transplant center prior to implantation into a transplant recipient. The provider inserts a sterile thin cannula into the donor liver vasculature (commonly the portal vein or hepatic artery ostium) to permit connection to an ex vivo perfusion device or cold storage perfusion circuit that preserves the organ between procurement and transplantation. The clinical workflow includes organ recovery in the operating room, back-table preparation by the transplant surgeon or procurement surgeon, cannulation of the graft for perfusion solution delivery and sampling, transport or continuous perfusion on a preservation device, and later removal of the cannula immediately prior to implantation in the recipient or after completion of perfusion assessment. Typical site of service is an acute care hospital operating room or organ preservation facility/organ procurement organization laboratory. Typical personnel include transplant surgeons, surgical assistants, perfusion specialists, and OR nursing staff. The encounter is not patient-facing in the sense of direct recipient surgery while the organ is being cannulated ex vivo; it is part of the organ preservation and transplant workflow for a liver allograft destined for transplantation.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for cannulation and documentation supports unusually complex back-table work. |
53 | Discontinued procedure | Use if cannulation attempt is started but then abandoned for documented clinical reasons before completion. |
54 | Surgical care only | Use when a provider performs only the surgical aspect of cannula insertion and another provider manages postoperative care. |
55 | Postoperative management only | Use when a provider bills only for post-op management of the graft after cannulation by another surgeon. |
62 | Two surgeons | Use when two surgeons work together as co-surgeons for the cannulation due to complexity. |
66 | Surgical team | Use when an integrated surgical team model is documented for the cannulation procedure. |
73 | Discontinued outpatient hospital/ambulatory surgery before anesthesia | Use if cannulation is cancelled after initiation of setup but before cannula insertion in an ambulatory setting. |
78 | Unplanned return to the OR by same surgeon following initial procedure | Use if the graft requires re-cannulation in an unplanned return to the OR during the same transplant episode. |
80 | Assistant surgeon | Use when an assistant surgeon is present and performs assistant-level tasks during cannulation. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist service | Use when an authorized advanced practice provider performs or assists with the cannulation within their scope. |

| 2086S0125X | Transplant Surgery | Specialty designation for surgeons focused on solid organ transplantation including liver allograft preparation. |
| 2084P0800X | Physician Assistant | PAs often assist in OR and back-table procedures and may perform tasks such as cannula placement under supervision. |
