What is the ICD-10 code for atrioventricular block?

The ICD-10 codes for atrioventricular block range from I44.0 to I44.2, covering first-degree, second-degree, and complete AV block.

How do you code a complete AV block?

Use ICD-10 code I44.2 for complete AV block, ensuring documentation includes ECG findings of complete dissociation of P waves and QRS complexes.

When should Z95.0 be used in AV block coding?

Use Z95.0 when a pacemaker is present and relevant to the treatment of AV block, ensuring documentation links the device to the condition.

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
I44.0	First-degree atrioventricular block	Use when documentation specifies first-degree AV block with a PR interval >0.20s.	ECG showing PR interval consistently >0.20s
I44.1	Second-degree atrioventricular block	Use when documentation specifies Mobitz I or II with corresponding ECG findings.	ECG showing non-conducted P waves with fixed PR intervals
I44.2	Complete atrioventricular block	Use when documentation specifies complete AV block with ECG confirmation.	ECG showing complete dissociation of P waves and QRS complexes

Documentation & Coding Risks

Avoid these common issues when documenting Atrioventricular Block.

Vague documentation of heart block

Impact

Clinical: Inadequate treatment planning, Regulatory: Non-compliance with coding standards, Financial: Potential underbilling

Mitigation

Use specific terminology like 'Mobitz II', Include ECG findings in documentation

Undercoding by using only I44.2 when transient complete block occurs with persistent lower-grade blocks.

Impact

Reimbursement: Potential underpayment due to incomplete coding., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Code all coexisting blocks (I44.0 + I44.1 + I44.2).

Confusing Mobitz I with Mobitz II.

Impact

Reimbursement: Incorrect DRG assignment., Compliance: Potential audit risk., Data Quality: Misrepresentation of clinical severity.

Mitigation

Ensure documentation specifies type of block and corresponding ECG findings.

Incomplete coding of AV block

Impact

Failure to code all coexisting blocks can lead to audit findings.

Mitigation

Ensure documentation supports all coded blocks.
