R93.422

Abnormal radiologic findings on diagnostic imaging of left kidney

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R93.422 is a billable code used to indicate a diagnosis of abnormal radiologic findings on diagnostic imaging of left kidney.

Key Diagnostic Point:

R93.422 is used to classify abnormal findings observed in diagnostic imaging studies of the left kidney, such as ultrasound, CT scans, or MRIs. These findings may include masses, cysts, stones, or other anomalies that do not have a specific diagnosis associated with them. The abnormal findings can be incidental or indicative of underlying pathology, necessitating further investigation or monitoring. Common symptoms that may accompany these findings include flank pain, hematuria, or changes in urinary habits. The clinical context is crucial, as the abnormality may be benign or suggestive of more serious conditions such as renal tumors or obstructive uropathy. Accurate coding requires thorough documentation of the imaging results and any related clinical symptoms to ensure appropriate follow-up and management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in imaging findings interpretation
  • Need for correlation with clinical symptoms
  • Potential for incidental findings
  • Differentiation from other renal conditions

Audit Risk Factors

  • Inadequate documentation of imaging results
  • Failure to link findings to clinical symptoms
  • Misinterpretation of incidental findings
  • Lack of follow-up documentation

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Documentation should include detailed imaging results, clinical symptoms, and any follow-up plans or referrals.

Common Clinical Scenarios

Patients presenting with flank pain or hematuria who undergo imaging that reveals abnormal findings.

Billing Considerations

Consideration of the patient's history and risk factors for renal disease is essential for accurate coding.

Emergency Medicine

Documentation Requirements

Acute care documentation must include the reason for imaging, findings, and immediate management plans.

Common Clinical Scenarios

Patients with acute flank pain or trauma who require urgent imaging.

Billing Considerations

Rapid assessment and documentation are critical in emergency settings to ensure appropriate coding.
