Diagnosis Overview

What is Abnormal Findings On Diagnostic Imaging?
Essential facts and insights about Abnormal Findings on Diagnostic Imaging

Key Clinical Considerations:

  • Presence of abnormal findings on diagnostic imaging that cannot be classified elsewhere
  • Findings must be unexpected and not related to a known disease or condition

Clinical Information

Clinical Criteria & Documentation Requirements

  • Detailed description of the abnormal findings
  • Type of imaging used and the area of the body imaged
  • Clinical significance of the findings, if known
  • Any follow-up or additional testing recommended

Coding Guidelines

Usage Guidelines & Examples

  • R93.8 is a nonspecific code used when the abnormal findings are not classified elsewhere
  • R93.89 is used for other specified abnormal findings on diagnostic imaging

Code Exclusions

Important Exclusions

  • Abnormal findings on antenatal screening of mother (O28.-)
  • Abnormal findings on diagnostic imaging of central nervous system (R90.-)

Specialty Focus

Primary Specialty

Radiology

Specialty Applications

  • Unexplained abnormalities found on imaging studies
  • Incidental findings on imaging studies done for other reasons

Coding Complexity

High Complexity

This diagnosis requires careful attention to:

  • Comprehensive clinical documentation
  • Accurate code selection based on clinical criteria
  • Proper exclusion considerations
  • Specialty-specific coding guidelines

Documentation

Documentation Templates

Template 1

Abnormal findings on [type of imaging] of [body part]. Clinical significance unknown at this time.

Template 2

Incidental finding on [type of imaging] of [body part]. Follow-up or additional testing recommended.

Billing Information

Billing Considerations

  • Ensure proper documentation for billing
  • Verify code specificity requirements
  • Check for any additional codes needed
  • Review payer-specific guidelines

Common Issues

  • Insufficient clinical documentation
  • Incorrect code selection
  • Missing supporting diagnoses
  • Timing and frequency documentation

Frequently Asked Questions

Can these codes be used if the abnormality is later diagnosed?

No, once a diagnosis is confirmed, the specific code for that diagnosis should be used.

When should these codes be used?

These codes should be used when abnormal findings are discovered on imaging studies, but a definitive diagnosis has not yet been made.
