Primary ICD-10-CM Code for atrial fibrillation unspecified
Decision Criteria
documentation Criteria
- Documentation must lack specific type of AF
clinical Criteria
- EKG confirms AF but no specific type documented
Applicable To
- Atrial fibrillation NOS
- AFib unspecified type
Clinical Validation Requirements
- EKG showing irregularly irregular rhythm without discrete P waves
- No documentation specifying paroxysmal, persistent, or permanent AF
Code-Specific Risks
- May lead to claim denials if used without proper documentation
- Does not contribute as much to RAF scores as specific codes
Coding Notes
- Ensure documentation explicitly states 'atrial fibrillation, type unspecified' if using this code.
Ancillary Codes

Z86.79Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Atrial Fibrillation Unspecified to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I48.91.
Impact
Clinical: Inadequate clinical validation, Regulatory: Potential audit issues, Financial: Claim denials due to insufficient documentation
Mitigation Strategy
Always include EKG results in documentation, Use templates to ensure completeness
Impact
Reimbursement: Incorrect coding may lead to reduced reimbursement, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Use I48.21 for permanent AF
Impact
High risk of audit if unspecified codes are used without justification
Mitigation Strategy
Ensure documentation supports the use of unspecified codes
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.
