| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I44.2 | Complete atrioventricular block | Use when complete AV block is confirmed by ECG and associated with symptoms like syncope. |
|
| I44.1 | Second-degree atrioventricular block | Use when second-degree AV block is documented, particularly Mobitz II. |
|
| I44.0 | First-degree atrioventricular block | Use when a prolonged PR interval is documented without symptoms. |

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 Atrioventricular Node Disorders
Primary ICD-10-CM Codes for atrioventricular node
Decision Criteria
clinical Criteria
- Complete dissociation between atrial and ventricular activity on ECG
Applicable To
- Third-degree AV block
Excludes
- Asystole (R00.1)
Clinical Validation Requirements
- ECG showing complete dissociation between P waves and QRS complexes
- Ventricular rate <40 bpm
Code-Specific Risks
- Misclassification as asystole instead of complete AV block
Coding Notes
- Ensure complete documentation of ECG findings to support the use of I44.2.
I44.1 - Second-degree atrioventricular block
Use when second-degree AV block is documented, particularly Mobitz II.
Applicable To
- Mobitz type I and II
Clinical Validation Requirements
- ECG showing non-conducted P waves without progressive PR prolongation
Coding Notes
Document the specific type of second-degree block to ensure accurate coding.
I44.0 - First-degree atrioventricular block
Use when a prolonged PR interval is documented without symptoms.
Applicable To
- Prolonged PR interval
Clinical Validation Requirements
- PR interval >200ms on ECG
Coding Notes
First-degree block is often incidental and may not require coding unless symptomatic.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Amyloidosis, unspecified
E85.4Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Atrioventricular Node Disorders to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I44.2.
Impact
Clinical: Misdiagnosis and inappropriate treatment., Regulatory: Potential audit issues., Financial: Incorrect billing and reimbursement.
Mitigation Strategy
Ensure detailed ECG interpretation, Use specific terminology for block types
Impact
Reimbursement: Incorrect DRG assignment leading to reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Code I44.2 for complete AV block when ECG shows dissociation.
Impact
Failure to document ECG findings can lead to audit discrepancies.
Mitigation Strategy
Ensure all ECG findings are documented and linked to the diagnosis.
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.
