R93.429

Abnormal radiologic findings on diagnostic imaging of unspecified kidney

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

Code Description

ICD-10 R93.429 is a billable code used to indicate a diagnosis of abnormal radiologic findings on diagnostic imaging of unspecified kidney.

Key Diagnostic Point:

R93.429 is used to classify abnormal findings observed in diagnostic imaging studies of the kidney that do not fall into more specific categories. These findings may include anomalies such as masses, cysts, calcifications, or other structural abnormalities that are detected through imaging modalities like ultrasound, CT scans, or MRIs. The unspecified nature of the kidney in this code indicates that the exact location or type of abnormality is not detailed, which can occur in cases where imaging is performed for vague symptoms or routine screenings. Clinicians may encounter patients with nonspecific symptoms such as flank pain, hematuria, or renal dysfunction, prompting imaging studies that reveal these abnormalities. Accurate coding is essential for proper patient management and billing, as it reflects the complexity of the patient's condition and the necessity for further evaluation or intervention.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Unspecified nature of the kidney can lead to ambiguity in documentation.
  • Requires correlation with clinical findings for accurate coding.
  • Potential for misinterpretation of imaging results.
  • Need for comprehensive documentation to support the diagnosis.

Audit Risk Factors

  • Inadequate documentation supporting the abnormal finding.
  • Failure to link imaging findings to clinical symptoms.
  • Use of the code without appropriate imaging reports.
  • Inconsistent coding practices among different providers.

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed clinical history, imaging reports, and correlation with laboratory findings.

Common Clinical Scenarios

Patients presenting with vague abdominal pain or routine check-ups revealing incidental findings.

Billing Considerations

Ensure that all imaging findings are clearly documented and linked to the patient's clinical presentation.

Emergency Medicine

Documentation Requirements

Acute care documentation including reason for imaging, findings, and any immediate interventions.

Common Clinical Scenarios

Patients with acute flank pain or hematuria requiring urgent imaging.

Billing Considerations

Rapid documentation is crucial; ensure that imaging results are promptly communicated and linked to the diagnosis.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more detailed coding, but it has also introduced complexity with unspecified codes like R93.429. Coders must ensure they are using the most accurate codes based on the documentation available.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more detailed coding, but it has also introduced complexity with unspecified codes like R93.429. Coders must ensure they are using the most accurate codes based on the documentation available.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more detailed coding, but it has also introduced complexity with unspecified codes like R93.429. Coders must ensure they are using the most accurate codes based on the documentation available.
