Diagnosis Overview

What is Abnormal Chest Imaging?

Essential facts and insights about Abnormal Chest Imaging

Key Clinical Considerations:

Presence of abnormal findings on diagnostic imaging of lung
Unusual or unexpected findings in chest X-ray, CT scan, or MRI

Clinical Information

Clinical Criteria & Documentation Requirements

Detailed description of the abnormal findings
Specific location of the abnormality in the chest
Type of imaging modality used
Clinical relevance of the abnormal findings

Coding Guidelines

Usage Guidelines & Examples

R91.1 is used for solitary pulmonary nodule, while R91.8 is for other nonspecific abnormal findings in lung
R93.8 is for abnormal findings on diagnostic imaging of other specified body structures

Code Exclusions
