CodeDescriptionWhen to UseKey Documentation
J21.0Acute bronchiolitis due to respiratory syncytial virusUse when RSV is confirmed as the causative agent.
  • Positive RSV PCR test
  • Symptoms of wheezing and retractions
J21.9Acute bronchiolitis, unspecifiedUse when the causative virus is not identified.
  • Symptoms of bronchiolitis without identified virus

Clinical Decision Support

Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Decision Criteria

clinical Criteria

  • RSV confirmed by PCR test

documentation Criteria

  • Documented symptoms of acute bronchiolitis

Applicable To

  • RSV bronchiolitis

Excludes

  • Chronic bronchiolitis
  • Asthma

Clinical Validation Requirements

  • Positive RSV PCR test
  • Symptoms of wheezing and retractions

Code-Specific Risks

  • Requires virologic confirmation
  • Incorrect use without lab results

Coding Notes

  • Ensure RSV is confirmed through lab testing before using J21.0.

Ancillary Codes

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

Contact with and (suspected) exposure to environmental tobacco smoke

Z77.22
Use when there is documented exposure to tobacco smoke.

Contact with and (suspected) exposure to COVID-19

Z20.822
Use if there is documented exposure to COVID-19.

Differential Codes

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

Unspecified asthma, uncomplicated

J45.909
Asthma typically presents with recurrent wheezing and responds well to bronchodilators.

Acute bronchitis, unspecified

J20.9
Bronchitis is more common in older children and adults and involves larger airways.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Bronchiolitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code J21.0.

Impact

Clinical: Missed opportunity to address environmental factors., Regulatory: Non-compliance with documentation standards., Financial: Potential loss of additional reimbursement.

Mitigation Strategy

Always ask about and document exposure to tobacco smoke., Use Z77.22 when exposure is confirmed.

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data reporting.

Mitigation Strategy

Ensure RSV is confirmed by PCR or antigen test before coding.

Impact

Coding J21.0 without lab confirmation of RSV.

Mitigation Strategy

Ensure lab results are documented before coding.

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.

Example Documentation

4-month-old male presents with cough and wheezing. RSV PCR positive. Diagnosis: Acute bronchiolitis due to RSV.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Bronchiolitis, treat with albuterol.
Good Documentation Example
Acute RSV bronchiolitis with SpO2 92%, intercostal retractions, positive Xpert® RSV PCR.
Explanation
The good example provides specific clinical details and lab confirmation, supporting the diagnosis.
