ICD-10-PCS Code For Urinary System: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CT1Y includes procedures performed to image the urinary system using planar nuclear medicine techniques. These ICD-10-PCS codes are used for inpatient documentation when single‑plane nuclear medicine imaging with introduction of radionuclide is performed to evaluate renal or urinary tract function or structure. Accurate coding within the ICD-10-PCS CT1Y group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Urinary System Planar Nuclear Medicine Imaging Procedure Overview

This procedure group includes planar nuclear medicine imaging procedures that target the urinary system and use radiopharmaceuticals to produce single‑plane images from captured radioactive emissions. Procedures involve introducing radioactive materials into the body and capturing emitted signals to evaluate renal and urinary tract structure and function. Accurate ICD-10-PCS coding for these procedures ensures inpatient records reflect the imaging performed and supports appropriate case mix assignment and reimbursement.

When to Use

Use a code from this group when inpatient care includes planar nuclear medicine imaging of the urinary system with administration of a radiopharmaceutical to obtain single‑plane images. These codes apply when the clinical intent is diagnostic evaluation of renal function, urinary drainage, obstruction, or other urinary tract abnormalities using radionuclide imaging.

CT1YYZZ	Planar Nuclear Medicine Imaging of Urinary System using Other Radionuclide

Typical Clinical Scenarios

A hospitalized elderly patient with acute flank pain, rising serum creatinine, and oliguria after recent pelvic surgery is suspected of having obstructive uropathy with compromised renal perfusion; clinicians obtain inpatient single‑plane renal radionuclide imaging to assess differential renal function and drainage patterns to guide urgent management. Typical codes: CT1YYZZ
A pediatric patient admitted electively for evaluation of congenital hydronephrosis and recurrent urinary tract infections undergoes planned inpatient planar radionuclide imaging of the urinary system to quantify split renal function and evaluate for reflux or obstruction prior to possible corrective surgery. Typical codes: CT1YYZZ
An adult inpatient with a complex history of prior ureteral stent placement presents with persistent hematuria and suspected impaired renal drainage; a bedside planar nuclear medicine study is performed to noninvasively assess renal function and post‑intervention drainage as part of complication evaluation. Typical codes: CT1YYZZ
