| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I25.110 | Atherosclerotic heart disease of native coronary artery with unstable angina pectoris | Use when atherosclerosis is present in native coronary arteries with documented unstable angina. |
|
| I25.750 | Atherosclerosis of coronary artery bypass graft(s), unspecified, with unstable angina pectoris | Use when atherosclerosis affects bypass grafts with unstable angina. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for atherosclerosis of coronary artery
Decision Criteria
clinical Criteria
- Presence of unstable angina confirmed by clinical tests
Applicable To
- Native coronary artery with unstable angina
Excludes
- Atherosclerosis of bypass grafts
Clinical Validation Requirements
- Coronary angiography showing >50% stenosis
- Stress test indicating ischemia
Code-Specific Risks
- Misclassification if angina type is not specified
Coding Notes
- Ensure angina type is documented to avoid unspecified coding.
I25.750 - Atherosclerosis of coronary artery bypass graft(s), unspecified, with unstable angina pectoris
Use when atherosclerosis affects bypass grafts with unstable angina.
Applicable To
- Bypass graft with unstable angina
Excludes
- Atherosclerosis of native coronary arteries
Clinical Validation Requirements
- Angiography showing graft stenosis
- Clinical documentation of unstable angina
Coding Notes
Ensure graft type and angina are specified.
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 Atherosclerosis of Coronary Artery to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I25.110.
Impact
Clinical: Inaccurate clinical records, Regulatory: Potential audit issues, Financial: Incorrect reimbursement
Mitigation Strategy
Always document graft status if applicable, Use templates to ensure completeness
Impact
Reimbursement: May lead to incorrect DRG assignment, Compliance: Non-compliance with coding guidelines, Data Quality: Decreased accuracy of clinical data
Mitigation Strategy
Ensure angina type is specified in documentation to use the correct code.
Impact
Using unspecified codes when specific angina type is documented
Mitigation Strategy
Implement documentation checks for angina type
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.
