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 CT2Y includes procedures performed to image functional urinary system structures using tomographic nuclear medicine techniques. These ICD-10-PCS codes are used for inpatient documentation when three dimensional, radionuclide-based imaging of the kidneys, ureters, bladder, or related urinary anatomy is performed. Accurate coding within the ICD-10-PCS CT2Y group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Urinary System Tomographic Nuclear Medicine Imaging Procedure Overview

This procedure group includes tomographic nuclear medicine imaging studies that introduce radioactive materials to generate three dimensional images of the urinary system. Procedures target the kidneys, ureters, bladder, and related urinary structures and capture radioactive emissions to produce cross-sectional functional imaging. Accurate coding of these inpatient procedures ensures the clinical action and anatomical target are properly documented and supports correct case mix assignment and reimbursement.

When to Use

Use a code from this group when a patient undergoes radionuclide-based tomographic imaging of the urinary system during an inpatient stay. Codes apply when radioactive material is introduced and three dimensional imaging is acquired to evaluate urinary structure or function.

ICD-10-PCS Code	Description
CT2YYZZ	Tomographic (Tomo) Nuclear Medicine Imaging of Urinary System using Other Radionuclide

Typical Clinical Scenarios

An elderly patient hospitalized with acute obstructive uropathy and worsening renal function after ureteral stone migration; inpatient evaluation is needed to assess differential renal function and detect focal obstruction versus global decreased uptake. A tomographic radionuclide imaging study is performed to provide three-dimensional functional assessment of the kidneys and urinary drainage patterns to guide urgent management. Typical codes: CT2YYZZ
A middle-aged patient admitted electively for complex hematuria workup after outpatient cystoscopy was nondiagnostic; inpatient multidisciplinary evaluation is planned to characterize renal parenchymal function and localize a potential bleeding source within the urinary tract. A tomographic nuclear medicine study using an appropriate radionuclide is obtained to visualize functional renal tissue and dynamic excretion in three dimensions. Typical codes: CT2YYZZ
A pediatric patient with recurrent urinary tract infections and suspected vesicoureteral reflux is admitted for inpatient observation following febrile sepsis; detailed assessment of renal cortical function and differential uptake is required to evaluate scarring and guide further surgical planning. A tomographic radionuclide imaging procedure is performed to generate three-dimensional functional images of the urinary system. Typical codes: CT2YYZZ
