| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E05.00 | Thyrotoxicosis with diffuse goiter without thyrotoxic crisis | Use when hyperthyroidism is confirmed as the underlying cause of atrial fibrillation. |
|
| I48.0 | Paroxysmal atrial fibrillation | Use when AF episodes resolve spontaneously within 7 days. |

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 thyroid afibribillation
Decision Criteria
clinical Criteria
- Presence of suppressed TSH and elevated T4
Applicable To
- Graves' disease without crisis
Excludes
- E03.9 Hypothyroidism
Clinical Validation Requirements
- Suppressed TSH levels
- Elevated free T4 levels
Code-Specific Risks
- Incorrectly coding as hypothyroidism
Coding Notes
- Ensure documentation explicitly links thyrotoxicosis to atrial fibrillation.
I48.0 - Paroxysmal atrial fibrillation
Use when AF episodes resolve spontaneously within 7 days.
Applicable To
- AF that self-terminates within 7 days
Excludes
- I48.91 Unspecified atrial fibrillation
Clinical Validation Requirements
- EKG showing irregularly irregular rhythm
Coding Notes
Ensure AF type is specified in documentation.
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 Thyroid-Induced Atrial Fibrillation to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E05.00.
Impact
Clinical: Inaccurate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential reimbursement issues.
Mitigation Strategy
Review EKG findings for AF type, Document specific AF type in notes
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data affecting patient care.
Mitigation Strategy
Confirm TSH suppression and use E05.xx codes.
Impact
Incorrect sequencing of thyrotoxicosis and AF codes.
Mitigation Strategy
Train staff on proper sequencing rules.
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.
