| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I25.10 | Atherosclerotic heart disease of native coronary artery without angina pectoris | Use when atherosclerotic disease is present in native coronary arteries without angina symptoms. |

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Atherosclerotic Coronary Artery Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I25.10.
Impact
Clinical: Inaccurate clinical representation of patient condition., Regulatory: Non-compliance with ICD-10 coding standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Educate providers on documentation requirements., Implement EHR prompts for angina type.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Query provider for specific angina type and document accordingly.
Impact
Inadequate documentation of angina type can lead to audit issues.
Mitigation Strategy
Implement documentation templates and provider education.
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.
