CPT 44715: Small Intestine Graft Preparation for Transplantation

CPT code 44715 represents the surgical examination and preparation of a previously harvested small intestine for transplantation, including preparation of the superior mesenteric artery and vein for anastomosis. This code is relevant nationally for transplant centers, hospital surgical departments, and payers managing coverage for complex organ transplant procedures.

Major payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The code is most applicable in inpatient surgical settings where intestinal grafts are prepared and connected to recipient vasculature.

Readers will find an overview of the clinical service the code captures, the typical site of service, and the payer landscape that commonly reimburses for intestinal transplant–related surgical services. The publication outlines benchmarking and payment context where available, summarizes relevant billing considerations, and provides clinical context about what the procedure involves. Data not available in the input is noted where applicable.

Clinical & Coding Specifications

Clinical Context

A 52-year-old male with a history of mesenteric ischemia undergoes an intestinal transplantation procedure. In the operating room under general anesthesia, the transplant surgeon inspects and prepares the previously harvested donor small intestine for implantation into the recipient. This includes careful dissection and preparation of the donor superior mesenteric artery and vein, trimming of mesenteric tissue, ensuring adequate vessel length and quality, and readying the bowel for vascular anastomosis to the recipient's vasculature. Intraoperative steps include confirmation of bowel viability, control of mesenteric bleeding, and coordination with the transplant team to proceed to arterial and venous anastomoses. Typical site of service is an inpatient operating room in a tertiary care center or transplant hospital. The service type is a surgical transplant preparatory procedure performed by a transplant surgeon as part of intestinal transplantation surgery.

Coding Specifications

Modifier	Description	When to Use
`00`	No modifier recorded	Data not typically appended; avoid using for claims.
`22`	Increased procedural services	Use when work required is substantially greater than typical (e.g., significant adhesiolysis during preparation).
`26`	Professional component	Use if reporting only the surgeon's professional component separate from facility (rare for this code).
`52`	Reduced services	Use if the procedure was partially reduced or not completed as planned.
`53`	Discontinued procedure	Use if procedure was started but terminated due to patient instability before preparation completed.
`62`	Two surgeons	Use when two surgeons of different specialties perform distinct portions (eg, vascular surgeon assists with vessel preparation).
`66`	Surgical team	Use when services are furnished by a surgical team (complex transplant requiring team reporting).
`78`	Unplanned return to OR following initial procedure	Use for a return to the OR for revision of the intestinal preparation or vascular anastomosis.
