| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I48.0 | Paroxysmal atrial fibrillation | Use when episodes are self-terminating and last less than 48 hours. |
|
| I48.11 | Persistent atrial fibrillation | Use when atrial fibrillation persists beyond 7 days. |
|
| I47.1 | Supraventricular tachycardia | Use for regular narrow QRS complex tachycardia with HR >150 bpm. |

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

Use when atrial fibrillation persists beyond 7 days.
Applicable To
- Atrial fibrillation lasting more than 7 days
Excludes
- Paroxysmal atrial fibrillation (I48.0)
Clinical Validation Requirements
- AF >7 days requiring cardioversion
Coding Notes
Document the duration and any interventions attempted.
I47.1 - Supraventricular tachycardia
Use for regular narrow QRS complex tachycardia with HR >150 bpm.
Applicable To
- Regular narrow QRS complex tachycardia
Excludes
- Ventricular tachycardia (I47.2)
Clinical Validation Requirements
- ECG showing regular narrow QRS complex
Coding Notes
Ensure ECG findings are documented to support the code.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Irregular Heart Rhythm 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: Non-compliance with documentation standards., Financial: Potential for denied claims due to lack of specificity.
Mitigation Strategy
Always specify the type of atrial fibrillation., Query the provider if the type is not documented.
Impact
Reimbursement: May lead to reduced reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases the accuracy of clinical data.
Mitigation Strategy
Always document and code the specific type of arrhythmia.
Impact
High risk of audit if unspecified codes are used without justification.
Mitigation Strategy
Ensure documentation supports the most specific code possible.
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.
