Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves procurement and preparation of a cadaveric donor kidney for transplantation. In a tertiary transplant center, an organ procurement team receives a recovered donor kidney from an outside facility or from the hospital’s deceased donor program. The organ arrives on ice in preservation solution; the transplant surgeon or designated surgical assistant performs a standard back-table preparation in the operating room or a dedicated sterile back-table area. The workflow includes inspection, removal of excess perinephric fat, trimming and ligation of donor vessels, assessment of ureter length and viability, reconstruction or trimming of the renal artery/vein as needed, perfusion flush checks, and placement of a preservation cuff or stent when indicated. After preparation, the kidney is packaged and transported to the recipient operating room for implantation or handed directly to the implanting surgeon when recipient surgery is concurrent. Documentation includes donor identifiers, ischemia times, details of any anatomic variants or repairs, and any unusual circumstances that might affect organ function.
