Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I44.0 | First-degree atrioventricular block | Use when documentation specifies first-degree AV block with a PR interval >0.20s. |
|
| I44.1 | Second-degree atrioventricular block | Use when documentation specifies Mobitz I or II with corresponding ECG findings. |
|
| I44.2 | Complete atrioventricular block | Use when documentation specifies complete AV block with ECG confirmation. |

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

Use when documentation specifies Mobitz I or II with corresponding ECG findings.
Applicable To
- Mobitz I
- Mobitz II
Excludes
- First-degree AV block
- Complete AV block
Clinical Validation Requirements
- ECG showing non-conducted P waves with fixed PR intervals
Coding Notes
Specify type of block (Mobitz I or II) in documentation.
I44.2 - Complete atrioventricular block
Use when documentation specifies complete AV block with ECG confirmation.
Applicable To
- Third-degree AV block
Excludes
- First-degree AV block
- Second-degree AV block
Clinical Validation Requirements
- ECG showing complete dissociation of P waves and QRS complexes
Coding Notes
Document escape rhythm characteristics.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Atrioventricular 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: Inadequate treatment planning, Regulatory: Non-compliance with coding standards, Financial: Potential underbilling
Mitigation Strategy
Use specific terminology like 'Mobitz II', Include ECG findings in documentation
Impact
Reimbursement: Potential underpayment due to incomplete coding., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Code all coexisting blocks (I44.0 + I44.1 + I44.2).
Impact
Reimbursement: Incorrect DRG assignment., Compliance: Potential audit risk., Data Quality: Misrepresentation of clinical severity.
Mitigation Strategy
Ensure documentation specifies type of block and corresponding ECG findings.
Impact
Failure to code all coexisting blocks can lead to audit findings.
Mitigation Strategy
Ensure documentation supports all coded blocks.
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.
