| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R94.31 | Abnormal electrocardiogram [ECG] [EKG] | Use when ECG findings are abnormal but do not meet criteria for a specific diagnosis. |
|
| I48.91 | Unspecified atrial fibrillation | Use when atrial fibrillation is confirmed by ECG. |

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

Decision Criteria
clinical Criteria
- ECG shows nonspecific changes without a definitive diagnosis.
coding Criteria
- No specific arrhythmia or conduction disorder is documented.
Applicable To
- Nonspecific ECG changes
Excludes
- Specific arrhythmias (I44-I49)
Clinical Validation Requirements
- Documented nonspecific T-wave inversion
- Prolonged QT interval without a specific diagnosis
Code-Specific Risks
- Risk of overuse when specific diagnoses are available
Coding Notes
- Ensure documentation supports the use of R94.31 by detailing the specific ECG findings.
I48.91 - Unspecified atrial fibrillation
Use when atrial fibrillation is confirmed by ECG.
Applicable To
- Atrial fibrillation not otherwise specified
Excludes
- Atrial flutter (I48.92)
Clinical Validation Requirements
- Irregularly irregular rhythm on ECG
- Absence of P waves
Coding Notes
Do not use R94.31 with I48.91 unless additional nonspecific findings are documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Chest pain, unspecified
R07.9Differential 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 Abnormal Electrocardiogram to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R94.31.
Impact
Clinical: May lead to misinterpretation of patient condition., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials or reduced reimbursement.
Mitigation Strategy
Use structured documentation templates., Ensure all ECG findings are detailed.
Impact
Reimbursement: May lead to incorrect DRG assignment and reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use the specific arrhythmia code alone unless additional nonspecific findings are documented.
Impact
Using R94.31 when a specific arrhythmia is documented.
Mitigation Strategy
Educate providers on proper code selection and documentation requirements.
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.
