ICD-10-PCS Code For Renal Arteries, Bilateral: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B428 includes procedures performed to visualize vascular structures in the renal arteries, bilateral. These ICD-10-PCS codes are used for inpatient documentation when computerized tomography scans with computer reformatted multiplanar images of the bilateral renal arteries are performed for diagnostic evaluation or treatment planning. Accurate coding within the ICD-10-PCS B428 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Renal Arteries Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging procedures that target the bilateral renal arteries within the lower arterial system. These procedures involve computer reformatted multiplanar images developed from multiple external ionizing radiation exposures to visualize vessel anatomy and pathology. Accurate ICD-10-PCS coding of these imaging procedures ensures inpatient documentation reflects the exact study performed and supports correct case mix assignment and reimbursement.

When to Use

Use these codes when a CT scan with computer reformatted multiplanar images of both renal arteries is performed during an inpatient stay. Select the code when the imaging study specifically targets the bilateral renal arteries and the procedure is documented as performed.

Typical Clinical Scenarios

A 68-year-old man is admitted with acute flank pain and sudden worsening of kidney function after a recent diagnosis of suspected renal artery stenosis. To evaluate bilateral renal artery anatomy and degree of stenosis for urgent diagnostic clarification and to guide potential revascularization, a CT scan with computer-reformatted multiplanar images of both renal arteries is performed using low osmolar intravascular contrast due to the patient’s chronic kidney disease and prior contrast reactions. The imaging study documents bilateral arterial narrowing and supports immediate inpatient management decisions. Typical codes: B4281ZZ
A 54-year-old woman with resistant hypertension is admitted for planned inpatient workup to determine secondary causes; noninvasive testing suggested bilateral renal artery abnormalities. For detailed vascular mapping prior to elective endovascular intervention, a CT angiographic study with computer-reformatted multiplanar images of the bilateral renal arteries is obtained using high osmolar contrast per institutional protocol to maximize arterial opacification. The study is performed to characterize lesion morphology and assist in procedural planning. Typical codes: B4280ZZ
A 60-year-old patient presents after a prior renal artery stenting procedure with recurrent hypertension and suspected in-stent restenosis. During the inpatient stay, a CT scan with computer-reformatted multiplanar images of the bilateral renal arteries is obtained without intravenous contrast documented (non-contrast advanced acquisition) to evaluate calcified plaque and hardware position; alternatively, when intravascular optical imaging adjuncts were used during follow-up evaluation, that specific imaging modifier is documented. The imaging is used to assess for restenosis or stent-related complications and to plan further management. Typical codes: B428Z2Z, B428ZZZ
