ICD-10-PCS Code For Renal Artery Right: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0479 includes procedures performed to dilate the lumen of the renal artery in the right kidney. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs endovascular or open dilation to restore or improve renal arterial blood flow. Accurate coding within the ICD-10-PCS 0479 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Renal Artery, Right Dilation Procedure Overview

Procedures in this group involve dilation of the right renal artery to expand the lumen of the artery and improve blood flow to the kidney. These interventions target the lower arterial system and typically use catheter-based techniques such as balloon angioplasty. Accurate ICD-10-PCS coding captures the specific root operation, body part, and approach, which is important for inpatient reimbursement and clinical record integrity.

Typical Clinical Scenarios

A 68-year-old patient with resistant hypertension and progressive decline in renal function is admitted for planned endovascular management after duplex ultrasound and CT angiography demonstrate focal high-grade stenosis of the right renal artery. The interventionalist performs percutaneous balloon angioplasty with placement of a single drug-eluting stent to restore renal perfusion and reduce renovascular hypertension. The procedure is performed via a percutaneous arterial access in the cath lab as a scheduled inpatient intervention to optimize blood pressure control and kidney function. Typical codes: 0479341, 047934Z
A 54-year-old patient presents emergently with sudden onset flank pain and acute worsening of kidney function; imaging shows an acute thrombosis with critical narrowing of the right renal artery. During urgent percutaneous intervention the team performs balloon dilation and deploys two intraluminal devices to re-establish flow. The patient is managed inpatient for close monitoring of renal function and anticoagulation after the emergent revascularization. Typical codes: 047935Z, 04793EZ
A 72-year-old patient returns with recurrent stenosis at a previously treated right renal artery site causing progressive hypertension and declining renal function; imaging confirms restenosis at the stent segment. The patient undergoes percutaneous endoscopic balloon angioplasty using a drug-coated balloon without placement of additional permanent devices to treat in-stent restenosis and improve vessel lumen patency. This inpatient procedure is performed to address the complication of prior intervention and avoid further renal injury. Typical codes: 04794DZ, 04794Z1
