| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I48.0 | Paroxysmal atrial fibrillation | Use when AF episodes are self-terminating and last less than 7 days. |
|
| I48.1x | Persistent atrial fibrillation | Use when AF persists beyond 7 days and requires intervention. |
|
| I48.2x | Chronic atrial fibrillation | Use for longstanding persistent or permanent AF with no plans for cardioversion. |
|
| I48.91 | Unspecified atrial fibrillation | Use only when the type of AF is not documented. |

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

Essential facts and insights about Atrial Fibrillation
Primary ICD-10-CM Codes for atrial fibrillation
Decision Criteria
clinical Criteria
- AF episodes resolve spontaneously within 7 days.
Applicable To
- Self-terminating AF
- Episodes lasting <7 days
Excludes
- Persistent AF
- Chronic AF
Clinical Validation Requirements
- ECG showing paroxysmal AF
- Patient history of episodes resolving within 7 days
Code-Specific Risks
- Misclassification if duration exceeds 7 days
Coding Notes
- Ensure documentation specifies 'paroxysmal' to avoid unspecified coding.
I48.1x - Persistent atrial fibrillation
Use when AF persists beyond 7 days and requires intervention.
Applicable To
- AF requiring intervention
- Duration >7 days
Excludes
- Paroxysmal AF
- Chronic AF
Clinical Validation Requirements
- ECG confirming persistent AF
- Documented failure of self-termination
Coding Notes
Documentation must specify 'persistent' to avoid unspecified coding.
I48.2x - Chronic atrial fibrillation
Use for longstanding persistent or permanent AF with no plans for cardioversion.
Applicable To
- Longstanding persistent AF
- Permanent AF
Excludes
- Paroxysmal AF
- Persistent AF
Clinical Validation Requirements
- ECG showing chronic AF
- No planned cardioversion
Coding Notes
Ensure documentation specifies 'chronic' or 'permanent' to avoid unspecified coding.
I48.91 - Unspecified atrial fibrillation
Use only when the type of AF is not documented.
Applicable To
- AF not otherwise specified
Excludes
- Paroxysmal AF
- Persistent AF
- Chronic AF
Clinical Validation Requirements
- Lack of specific AF type documentation
Coding Notes
Avoid using unspecified codes by ensuring detailed documentation.
Differential Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Atrial Fibrillation to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I48.0.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Fails to meet documentation standards., Financial: Potential for denied claims due to lack of specificity.
Mitigation Strategy
Always document current AF status and management plan.
Impact
Reimbursement: Unspecified codes may lead to lower reimbursement rates., Compliance: Increases risk of audits due to lack of specificity., Data Quality: Reduces accuracy of clinical data.
Mitigation Strategy
Ensure documentation specifies the type of AF (paroxysmal, persistent, chronic).
Impact
Increased audit risk due to lack of specificity in coding.
Mitigation Strategy
Ensure documentation specifies AF type and management details.
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.
