Applicable To
- History of atrial fibrillation
Excludes
- Current atrial fibrillation (I48.-)
Clinical Validation Requirements
- ECG showing sinus rhythm
- No current antiarrhythmic or anticoagulant therapy
- Documented resolution of atrial fibrillation
Code-Specific Risks
- Incorrectly coding active atrial fibrillation as history
Coding Notes

I48.91Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting History of Atrial Fibrillation to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z86.79.
Impact
Clinical: Misrepresentation of patient's current health status., Regulatory: Potential audit issues., Financial: Incorrect reimbursement.
Mitigation Strategy
Always include recent ECG results in documentation.
Impact
Reimbursement: Incorrect coding may lead to inappropriate DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records.
Mitigation Strategy
Use an active atrial fibrillation code if the patient is on anticoagulants.
Impact
Using Z86.79 when atrial fibrillation is active.
Mitigation Strategy
Verify current treatment and rhythm status before coding.
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.
