Decision Criteria

clinical Criteria

  • ECG shows QRS 110-119ms with rsr’ pattern.

documentation Criteria

  • Provider notes 'incomplete' in the diagnosis.

Applicable To

  • Right bundle-branch block not otherwise specified

Excludes

  • Complete right bundle-branch block (I45.19)

Clinical Validation Requirements

  • ECG showing QRS duration of 110-119ms
  • rsr’ pattern in V1-V2

Code-Specific Risks

  • Misclassification if documentation does not specify 'incomplete'.

Coding Notes

Use when IRBBB is secondary to pulmonary embolism.

Primary pulmonary hypertension

I27.0
Use when IRBBB is associated with pulmonary hypertension.

Differential Codes

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

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Incomplete Right Bundle Branch Block to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I45.10.

Impact

Clinical: May lead to misdiagnosis., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials.

Mitigation Strategy

Train providers on documentation standards., Use templates that prompt for QRS duration.

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding standards., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use I45.19 for complete RBBB with QRS ≥120ms.

Impact

Inaccurate or incomplete documentation of ECG findings.

Mitigation Strategy

Implement regular training and audits of documentation practices.

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.

Primary Care Visit

Specialty: Internal Medicine

Required Elements

  • ECG findings
  • Clinical symptoms
  • Follow-up recommendations

Example Documentation

Asymptomatic patient with ECG showing incomplete RBBB (QRS 112ms, rsr’ in V1). No evidence of cardiopulmonary disease. Advised annual follow-up.

Examples: Poor vs. Good Documentation

Poor Documentation Example
ECG shows RBBB.
Good Documentation Example
12-lead ECG demonstrates incomplete RBBB with QRS duration 115ms, rsR’ pattern in V1, and slurred S wave in lead I.
Explanation
The good example provides specific ECG findings and clarifies the incomplete nature of the block.
