| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I25.110 | Atherosclerotic heart disease of native coronary artery with unstable angina pectoris | Use when the patient presents with unstable angina symptoms and CAD is confirmed. |
|
| I25.111 | Atherosclerotic heart disease of native coronary artery with angina pectoris with documented spasm | Use when angina is due to coronary artery spasm and CAD is confirmed. |

I25.111 - Atherosclerotic heart disease of native coronary artery with angina pectoris with documented spasm
Use when angina is due to coronary artery spasm and CAD is confirmed.
Applicable To
- Angina with spasm
Excludes
- Vasospastic angina without CAD (I20.1)
Clinical Validation Requirements
- Angiographic evidence of spasm
- Response to nitroglycerin
Coding Notes
Document spasm evidence to support code use.
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 Artery Disease with Angina 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 treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential revenue loss.
Mitigation Strategy
Use templates to ensure comprehensive documentation., Regular training on documentation standards.
Impact
Reimbursement: Potential underpayment due to incorrect coding., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure angina is documented if antianginal medications are prescribed.
Impact
Inaccurate documentation of angina type can lead to audit issues.
Mitigation Strategy
Implement regular documentation audits and training.
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.
