R91-R94Primary Range

Abnormal findings on diagnostic imaging and in function studies, without diagnosis

This range includes codes for abnormal findings on diagnostic imaging, such as chest X-rays, that do not have a definitive diagnosis.

Pneumonia and influenza

This range is relevant when a specific diagnosis like pneumonia is confirmed following an abnormal chest X-ray.

Key Information: ICD-10 code for abnormal chest X-ray

Essential facts and insights about Abnormal Chest X-ray

Billable Code

Decision Criteria

clinical Criteria

  • Presence of nonspecific findings on chest X-ray

coding Criteria

  • No definitive diagnosis available at the time of coding

documentation Criteria

  • Radiologist report must specify findings as nonspecific

Applicable To

  • Nonspecific lung opacities
  • Unexplained lung nodules

Excludes

  • Specific diagnoses like pneumonia (J18.9)
  • Lung cancer (C34.90)

Clinical Validation Requirements

  • Radiologist report indicating nonspecific findings
  • Follow-up imaging or tests pending

Code-Specific Risks

  • Using R91.8 when a specific diagnosis is available
  • Failure to update code after further diagnostic clarification

Coding Notes

  • Ensure documentation specifies the nature of the abnormality and any follow-up actions.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Pneumonia, unspecified organism

J18.9
Use if pneumonia is confirmed following initial R91.8 coding.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Solitary pulmonary nodule

R91.1
Use R91.1 if a solitary nodule is confirmed by further imaging.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Abnormal Chest X-ray to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R91.8.

Impact

Clinical: May delay further diagnostic workup., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials.

Mitigation Strategy

Use specific terminology in radiology reports., Ensure clear communication between radiologists and referring physicians.

Impact

Reimbursement: Incorrect coding may lead to claim denials or reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Impacts accuracy of patient records and data analytics.

Mitigation Strategy

Update to a specific code once a definitive diagnosis is confirmed.

Impact

High risk of audit if nonspecific codes are used without proper documentation.

Mitigation Strategy

Ensure all findings are documented with specific details and follow-up plans.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Emergency Department Chest X-ray

Specialty: Radiology

Required Elements

  • Indication for X-ray
  • Number of views
  • Specific findings
  • Comparison with prior studies

Example Documentation

Indication: Persistent cough. Technique: PA and lateral views. Findings: 2.5cm opacity in right lower lobe. Impression: Nonspecific opacity, recommend follow-up CT.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Abnormal CXR.
Good Documentation Example
PA and lateral views show 2.5cm opacity in right lower lobe, recommend follow-up CT.
Explanation
The good example provides specific findings and a recommendation for follow-up, improving clarity and coding accuracy.
