ICD-10-PCS Code For Kidney Transplant: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BT29 includes procedures performed to image the transplanted kidney in the urinary system using computerized tomography. These ICD-10-PCS codes are used for inpatient documentation when cross-sectional multiplanar CT imaging is performed to assess the kidney transplant for function, complications, or vascular and structural issues. Accurate coding within the ICD-10-PCS BT29 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Kidney Transplant Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging procedures directed at the kidney transplant within the urinary system. These procedures involve computer reformatted multiplanar images developed from multiple exposures of external ionizing radiation to evaluate the transplanted kidney and surrounding structures. Accurate ICD-10-PCS coding for these imaging procedures ensures correct inpatient documentation and supports appropriate reimbursement and case mix assignment.

When to Use

Use a code from this group when an inpatient computerized tomography study with computer reformatted multiplanar images is performed specifically to evaluate a kidney transplant. Select the appropriate code when the CT and image reconstruction are documented as directed at the transplanted kidney for assessment of function, complication, or surrounding structures.

Typical Clinical Scenarios

A 58-year-old kidney transplant recipient is admitted from the emergency department with sudden onset flank pain, decreased urine output, and rising serum creatinine over 24 hours. Clinical concern is acute vascular compromise (renal artery thrombosis or severe stenosis) of the transplanted kidney; an inpatient CT study with intravenous contrast is ordered to evaluate renal perfusion and vascular anatomy with multiphase imaging and reformatted multiplanar reconstructions. Because both noncontrast and contrast-enhanced phases are obtained to assess for hemorrhage and vascular flow, a code reflecting an unenhanced and enhanced CT of the transplanted kidney is appropriate. Typical codes: BT2900Z, BT2910Z
A 45-year-old stable outpatient is admitted electively for surveillance imaging after recent transplantation complicated by delayed graft function; the team performs a planned contrast-enhanced CT to assess graft morphology, ureteral anastomosis, and peri-renal collections with high-resolution reformatted images. The procedure is elective and uses low-osmolar iodinated contrast for optimal image quality in a single contrast-enhanced acquisition with multiplanar reconstruction. Typical codes: BT291ZZ
A 63-year-old transplant patient is hospitalized for fever and elevated inflammatory markers with concern for perinephric abscess around the transplanted kidney. The inpatient workup includes a contrast-enhanced CT with both unenhanced and enhanced phases to detect fluid collections, gas, and to guide potential drainage, using an alternative contrast agent documented in the record. Because both unenhanced and enhanced imaging of the transplanted kidney are performed with the specified contrast type, the combined unenhanced and enhanced code for that contrast is selected. Typical codes: BT29Y0Z
