Primary ICD-10-CM Code for coronary artery disease with unstable angina
Decision Criteria
clinical Criteria
- Presence of CAD with unstable angina symptoms.
Applicable To
- Coronary artery disease with unstable angina
Excludes
- Unstable angina without CAD (I20.0)
Clinical Validation Requirements
- Dynamic ECG changes during pain
- Negative serial troponins (<99th percentile)
- Angiography showing ≥70% stenosis
Code-Specific Risks
- Incorrectly using I20.0 when CAD is present.
Coding Notes
- Ensure documentation specifies 'unstable angina' and links it to CAD.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Z79.84Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Coronary Artery Disease with Unstable 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: May lead to inappropriate treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Always specify 'unstable' or 'stable' angina in documentation.
Impact
Reimbursement: Incorrect coding can lead to lower reimbursement rates., Compliance: May result in non-compliance with coding guidelines., Data Quality: Affects the accuracy of clinical data and patient records.
Mitigation Strategy
Use I25.110 when CAD and unstable angina are both present.
Impact
Using I20.0 instead of I25.110 when CAD is present.
Mitigation Strategy
Ensure thorough documentation review and training on code selection.
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.
