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 6A4T includes procedures performed to induce hypothermia in structures of the urinary system. These ICD-10-PCS codes are used for inpatient documentation when extracorporeal or systemic lowering of body temperature is applied to the urinary system intraoperatively, often with donor organ protective thermal insulation. Accurate coding within the ICD-10-PCS 6A4T group is essential for proper inpatient reimbursement, as it captures the specific physiological therapy performed and determines appropriate case mix and payment.

Urinary System Hypothermia Procedure Overview

Procedures in this group involve the extracorporeal or systemic induction of hypothermia directed at the urinary system using donor organ protective thermal insulation during the intraoperative period. These interventions lower temperature to protect urinary system tissues or donor urinary organs during surgery and are coded within the Physiological Systems body system. Accurate ICD-10-PCS coding ensures the inpatient record reflects the specific hypothermia therapy performed and supports correct case mix and payment.

When to Use

Use a code from this group when intraoperative extracorporeal or systemic temperature-lowering therapy is intentionally applied to the urinary system, such as to protect donor urinary organs with thermal insulation. Assign these codes when documentation specifies hypothermia as the operation performed on the urinary system during the inpatient procedure.

ICD-10-PCS Code	Description
6A4T00A	Hypothermia of Urinary System using Donor Organ Protective Thermal Insulation, Single, Intraoperative

Typical Clinical Scenarios

A patient undergoing planned living-donor renal transplantation with anticipated ischemia time for the donor kidney. During the intraoperative period the transplant team applies donor organ protective thermal insulation and extracorporeal cooling directed at the urinary system to induce hypothermia of the donor organ and reduce metabolic demand while vascular anastomoses are performed. This intraoperative physiologic therapy is documented to protect the transplanted urinary organ. Typical codes: 6A4T00A
An adult presents emergently with severe trauma to the pelvis and bladder requiring urgent reconstructive surgery and temporary extracorporeal protection of native urinary tissues. Intraoperatively, clinicians use donor organ protective thermal insulation techniques adapted to the injured urinary structures and induce localized hypothermia to minimize ischemic injury during prolonged repair. The procedure is recorded as intraoperative hypothermia of the urinary system using protective thermal insulation. Typical codes: 6A4T00A
A patient previously transplanted months earlier develops graft dysfunction and requires intraoperative graft revision with prolonged revision time anticipated. During the revision operation the surgical team reapplies donor organ protective thermal insulation and extracorporeal hypothermia to the transplanted urinary organ to protect it while corrective vascular and ureteral repairs are performed. The intraoperative hypothermia intervention is documented as targeting the urinary system donor organ. Typical codes: 6A4T00A
