Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I25.10 | Atherosclerotic heart disease of native coronary artery without angina pectoris | Use when CAD is confirmed by imaging but the patient is asymptomatic. |
|
| I25.110 | Atherosclerotic heart disease of native coronary artery with unstable angina pectoris | Use when the patient has unstable angina with documented CAD. |

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
- Patient has CAD confirmed by imaging without symptoms.
Applicable To
- Asymptomatic coronary artery disease
Excludes
- Atherosclerosis of bypass graft (I25.7-)
Clinical Validation Requirements
- CT angiography showing ≥50% stenosis without ischemic symptoms
Code-Specific Risks
- Risk of under-documenting if angina is present but not recorded.
Coding Notes
- Ensure to document the absence of angina explicitly.
I25.110 - Atherosclerotic heart disease of native coronary artery with unstable angina pectoris
Use when the patient has unstable angina with documented CAD.
Applicable To
- Unstable angina
Excludes
- Postinfarction angina (I23.7)
Clinical Validation Requirements
- Unstable angina at rest with dynamic ST depression on telemetry
Coding Notes
Document angina type and severity clearly.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Coronary Arteriosclerosis 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 patient history representation., Regulatory: Potential audit issues., Financial: Incorrect DRG assignment.
Mitigation Strategy
Always document graft status if applicable.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use I25.118 for stable angina with CAD.
Impact
Incomplete angina documentation can lead to coding errors.
Mitigation Strategy
Implement a checklist for angina documentation.
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.
