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 CT6Y includes procedures performed to introduce radioactive materials for nonimaging nuclear medicine assay in the urinary system. These ICD-10-PCS codes are used for inpatient documentation when radioactive tracers are administered to evaluate urinary system function or body fluids related to the urinary tract. Accurate coding within the ICD-10-PCS CT6Y group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Urinary System Nonimaging Nuclear Medicine Assay Procedure Overview

Procedures in this group involve the introduction of radioactive materials into the body to perform nonimaging nuclear medicine assays that evaluate urinary system function and body fluids related to the urinary tract. These procedures target the urinary system and measure radioactive emissions from introduced radionuclides rather than producing diagnostic images. Accurate coding of these assays supports correct inpatient documentation and influences case mix classification and payment for services rendered.

When to Use

Use a code from this group when a radioactive tracer is administered specifically to evaluate urinary system function or to assay body fluids related to the urinary tract without obtaining diagnostic images. Select the appropriate code when the procedure performed is a nonimaging nuclear medicine assay of the urinary system and the documented radionuclide falls under the other radionuclide designation.

ICD-10-PCS Code	Description
CT6YYZZ	Nonimaging Nuclear Medicine Assay of Urinary System using Other Radionuclide

Typical Clinical Scenarios

An elderly inpatient with acute-on-chronic urinary retention and rising serum creatinine after recent ureteral stent placement has persistent oliguria despite bladder catheterization. Clinicians order a nonimaging nuclear medicine assay that introduces a radionuclide tracer to evaluate urinary clearance and renal urine output dynamics without obtaining diagnostic images to determine functional urine excretion contributing to renal dysfunction. The assay helps quantify urinary system function to guide ongoing inpatient management. Typical codes: CT6YYZZ
A hospitalized patient admitted for evaluation of unexplained proteinuria and suspected tubular dysfunction undergoes a planned nonimaging study during their inpatient stay. A radioactive tracer classified as other radionuclide is administered to assess urinary system function and measure excretory patterns of body fluids related to the urinary tract without producing images, providing functional data to support diagnosis and treatment planning. Typical codes: CT6YYZZ
A postoperative patient develops suspected urine leak after complex pelvic surgery with new-onset persistent drainage from a surgical drain and declining urine output. To localize and confirm abnormal urinary tract excretory function without performing imaging studies, clinicians perform a nonimaging nuclear medicine assay introducing an other radionuclide tracer to evaluate urinary system emission patterns and detect dysfunction or leakage of urinary fluids. Typical codes: CT6YYZZ
