ICD-10-PCS Code For Kidney, Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BT02 includes procedures performed to capture planar radiographic images of structures in the kidney, left. These ICD-10-PCS codes are used for inpatient documentation when a diagnostic plain radiographic image of the left kidney is obtained using external ionizing radiation recorded on a photographic or photoconductive plate. Accurate coding within the ICD-10-PCS BT02 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Kidney, Left Plain Radiography Procedure Overview

This procedure group includes plain radiographic imaging of the left kidney using external ionizing radiation captured on photographic or photoconductive plates. The procedures target the urinary system and involve acquisition of two-dimensional images for diagnostic evaluation of kidney anatomy and pathology. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it documents the specific imaging operation performed and supports appropriate case grouping and payment.

2	Body Part	Kidney, Left

When to Use

Use a code from this group when a two-dimensional plain radiographic image of the left kidney is acquired as part of inpatient diagnostic imaging. Do not use these codes for modalities other than plain radiography or for kidneys on the opposite side.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
BT020ZZ	Plain Radiography of Left Kidney using High Osmolar Contrast
BT021ZZ	Plain Radiography of Left Kidney using Low Osmolar Contrast
BT02YZZ	Plain Radiography of Left Kidney using Other Contrast
BT02ZZZ	Plain Radiography of Left Kidney

Typical Clinical Scenarios

An elderly patient is admitted with acute flank pain and gross hematuria after a fall; the inpatient team needs rapid two-dimensional imaging to evaluate for renal stones, fracture-related renal contusion, or displaced calcifications in the left kidney. A plain radiograph of the left kidney is obtained using external ionizing radiation to identify radiopaque stones or obvious structural disruption as an initial, quick diagnostic step. Typical codes: BT02ZZZ
A hospitalized patient with known chronic kidney disease is scheduled for a preoperative assessment before planned left renal biopsy to document baseline renal anatomy and detect calcifications that might affect the procedure; the study is a non-contrast two-dimensional radiograph performed on the inpatient ward. Because the imaging is plain radiography of the left kidney to guide procedural planning, a code indicating plain radiography without contrast is appropriate. Typical codes: BT02ZZZ
A patient in the inpatient setting develops suspected left renal arteriovenous malformation after recent contrast-enhanced studies; the team performs targeted plain radiographic imaging of the left kidney using low- or high-osmolar contrast agents to accentuate vascular or collecting system outlines when fluoroscopy or advanced imaging is temporarily unavailable. The plain radiograph is captured on a photoconductive/photographic plate using contrast to better delineate suspected abnormality. Typical codes: BT021ZZ, BT020ZZ
