| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I20.0 | Unstable angina | Use when the patient presents with new or worsening angina symptoms that occur at rest. |
|
| I20.1 | Angina pectoris with documented spasm | Use when coronary spasm is confirmed by angiography. |

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

Applicable To
- Prinzmetal angina
Excludes
- Coronary artery spasm without angina (I25.79)
Clinical Validation Requirements
- Angiogram showing transient coronary spasm
- Ergonovine challenge test
Coding Notes
Ensure spasm is documented via angiography.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Angina Pectoris to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I20.0.
Impact
Clinical: Incomplete clinical picture., Regulatory: Potential for audit issues., Financial: Risk of denied claims.
Mitigation Strategy
Use templates to ensure comprehensive documentation., Regular training on documentation standards.
Impact
Reimbursement: Potential underpayment due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreased accuracy in health records.
Mitigation Strategy
Always use the most specific code available based on documentation.
Impact
High risk of audit if unspecified codes are used without justification.
Mitigation Strategy
Educate staff on the importance of specificity in coding.
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.
