| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I20.0 | Unstable Angina | Use when the patient experiences chest pain at rest and meets clinical criteria for unstable angina. |

Decision Criteria
clinical Criteria
- Patient experiences chest pain at rest with EKG changes.
documentation Criteria
- Provider notes 'unstable angina' or 'angina at rest'.
Clinical Validation Requirements
- Episodes of chest pain at rest
- EKG changes without persistent ST elevation
- Normal or minimally elevated troponin levels
Code-Specific Risks
- Misclassification if CAD is present but not documented
Coding Notes
- Ensure documentation specifies 'unstable angina' or 'angina at rest' to avoid defaulting to I20.9.

Applicable To
- CAD with unstable angina
Excludes
- Stable angina (I25.119)
Clinical Validation Requirements

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Angina at Rest to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I20.0.
Impact
Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Educate providers on documentation requirements., Use templates to guide documentation.
Impact
Reimbursement: Incorrect coding may lead to lower reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient condition.
Mitigation Strategy
Use I25.119 if angina is implied by medication use.
Impact
Failure to specify angina type can lead to audit findings.
Mitigation Strategy
Implement documentation templates and provider education.
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.
