| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I48.20 | Chronic atrial fibrillation, unspecified | Use when documentation states 'chronic AF' without specifying type. |
|
| I48.21 | Permanent atrial fibrillation | Use when provider documents 'permanent AF'. |

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

Primary ICD-10-CM Codes for chronic atrial fibrillation
Decision Criteria
clinical Criteria
- AF documented as lasting more than 3 months without further classification.
Applicable To
- Chronic AF without further specification
Excludes
- Paroxysmal atrial fibrillation (I48.0)
Clinical Validation Requirements
- Documentation of atrial fibrillation lasting more than 3 months
- ECG confirmation of AF
Code-Specific Risks
- Risk of using unspecified code when more specific documentation is available.
Coding Notes
- Ensure documentation specifies 'chronic' to avoid unspecified coding.
I48.21 - Permanent atrial fibrillation
Use when provider documents 'permanent AF'.
Applicable To
- Permanent AF with no plans for cardioversion
Excludes
- Chronic atrial fibrillation, unspecified (I48.20)
Clinical Validation Requirements
- ECG showing AF with documentation of no plans for cardioversion
Coding Notes
Ensure documentation specifies 'permanent' to avoid unspecified coding.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Chronic Atrial Fibrillation to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I48.20.
Impact
Clinical: Leads to inappropriate treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential loss of reimbursement.
Mitigation Strategy
Educate providers on the importance of specifying AF type., Implement checklist for AF documentation.
Impact
Reimbursement: May affect DRG assignment and reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of patient records.
Mitigation Strategy
Ensure documentation specifies 'chronic' or 'permanent' to use I48.20 or I48.21 respectively.
Impact
Using unspecified codes when specific documentation is available.
Mitigation Strategy
Ensure documentation specifies AF type.
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.
