| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I25.10 | Atherosclerotic heart disease of native coronary artery without angina pectoris | Use when CAD is present without any angina symptoms. |
|
| I25.110 | Atherosclerotic heart disease of native coronary artery with unstable angina pectoris | Use when CAD is present with unstable angina 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.

Decision Criteria
clinical Criteria
- No angina symptoms present
Applicable To
- Coronary artery disease without angina
Excludes
- Coronary artery disease with angina (I25.11-)
Clinical Validation Requirements
- Documented evidence of atherosclerosis in coronary arteries
- Absence of angina symptoms
Code-Specific Risks
- Risk of under-documenting angina if present
Coding Notes
- Ensure documentation specifies absence of angina.
I25.110 - Atherosclerotic heart disease of native coronary artery with unstable angina pectoris
Use when CAD is present with unstable angina symptoms.
Applicable To
- Coronary artery disease with unstable angina
Excludes
- Coronary artery disease without angina (I25.10)
Clinical Validation Requirements
- Documentation of unstable angina symptoms
- ECG changes or elevated troponin levels
Coding Notes
Ensure documentation includes specific angina type and ECG findings.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting 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: Loss of important clinical history., Regulatory: Non-compliance with coding standards., Financial: Potential loss of reimbursement.
Mitigation Strategy
Always include past MI in patient history., Use specific codes for old MI.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases the accuracy of clinical data.
Mitigation Strategy
Always document and code the specific type of angina if present.
Impact
Inadequate documentation of unstable angina can lead to audit issues.
Mitigation Strategy
Ensure all clinical findings are documented clearly.
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.
