I47-I49Primary Range
Paroxysmal tachycardia, atrial fibrillation and flutter, and other cardiac arrhythmias
This range includes codes for various types of arrhythmias, including atrial fibrillation and tachycardia, which are common forms of irregular heartbeat.
Abnormalities of heart beat
This range includes non-specific codes for heart rhythm abnormalities, used when specific arrhythmias are not identified.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I48.0 | Paroxysmal atrial fibrillation | Use when atrial fibrillation is documented as paroxysmal or intermittent. |
|
| I48.1 | Persistent atrial fibrillation | Use when atrial fibrillation is documented as persistent. |
|
| R00.1 | Bradycardia, unspecified | Use when bradycardia is documented but not further specified. |

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

Essential facts and insights about Irregular Heartbeat
Primary ICD-10-CM Codes for irregular heartbeat
Decision Criteria
documentation Criteria
- Documentation must specify 'paroxysmal' or 'intermittent' for accurate coding.
Applicable To
- Intermittent atrial fibrillation
Excludes
- Chronic atrial fibrillation (I48.2)
Clinical Validation Requirements
- ECG confirmation of paroxysmal atrial fibrillation
- Patient history of intermittent episodes
Code-Specific Risks
- Misclassification as chronic if not specified
Coding Notes
- Ensure documentation specifies 'paroxysmal' to avoid misclassification.
I48.1 - Persistent atrial fibrillation
Use when atrial fibrillation is documented as persistent.
Applicable To
- Chronic persistent atrial fibrillation
Excludes
- Paroxysmal atrial fibrillation (I48.0)
Clinical Validation Requirements
- ECG showing atrial fibrillation lasting more than 7 days
- Clinical documentation of persistent nature
Coding Notes
Persistent atrial fibrillation should be clearly documented to avoid misclassification.
R00.1 - Bradycardia, unspecified
Use when bradycardia is documented but not further specified.
Excludes
- Sinus bradycardia (R00.1)
Clinical Validation Requirements
- Heart rate consistently below normal range without specific diagnosis
Coding Notes
Ensure documentation supports the use of an unspecified code.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Long-term (current) use of anticoagulants
Z79.01Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Irregular Heartbeat 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: Could result in audit findings., Financial: Potential loss of reimbursement for linked treatments.
Mitigation Strategy
Always document the reason for anticoagulant use in AF patients.
Impact
Reimbursement: Incorrect classification can affect DRG assignment and reimbursement., Compliance: May lead to compliance issues during audits., Data Quality: Impacts the accuracy of patient records and data reporting.
Mitigation Strategy
Ensure documentation specifies whether AF is paroxysmal, persistent, or permanent.
Impact
Use of unspecified codes can trigger audits.
Mitigation Strategy
Encourage detailed documentation to support specific 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.
