| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I44.0 | First degree atrioventricular block | Use when the patient has a prolonged PR interval on ECG without symptoms. |
|
| I44.1 | Second degree atrioventricular block | Use when ECG shows Mobitz I or II patterns. |
|
| I44.2 | Complete heart block | Use when ECG confirms complete AV dissociation. |

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

Z95.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Heart Block to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I44.0.
Impact
Clinical: Potential misdiagnosis., Regulatory: Non-compliance with documentation standards., Financial: Denied claims due to insufficient documentation.
Mitigation Strategy
Ensure detailed ECG findings are documented.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding standards., Data Quality: Inaccurate clinical data.
Mitigation Strategy
Ensure ECG findings are documented before coding.
Impact
Risk of audits due to insufficient documentation of ECG findings.
Mitigation Strategy
Ensure all ECG findings are documented and reviewed.
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.
