| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I20.0 | Unstable angina | Use when unstable angina is the primary reason for admission. |
|
| I25.11 | Atherosclerotic heart disease of native coronary artery with angina pectoris | Use when CAD is the underlying cause of 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.

Essential facts and insights about Angina
Primary ICD-10-CM Codes for angina
Decision Criteria
clinical Criteria
- Presence of rest angina or crescendo pattern.
Applicable To
- Crescendo angina
- Preinfarction angina
Excludes
- Angina pectoris with atherosclerosis of coronary artery bypass graft(s) (I25.7-)
Clinical Validation Requirements
- Rest angina, crescendo pattern, post-MI angina
- ST-T changes on ECG
Code-Specific Risks
- Misclassification if not properly documented as unstable.
Coding Notes
- Ensure documentation specifies unstable angina characteristics.
I25.11 - Atherosclerotic heart disease of native coronary artery with angina pectoris
Use when CAD is the underlying cause of angina.
Applicable To
- Coronary artery disease with angina
Excludes
- Angina pectoris without atherosclerosis (I20.-)
Clinical Validation Requirements
- Documented atherosclerosis with exertional chest pain relieved by rest/nitroglycerin.
Coding Notes
Sequence before I20.x if CAD is causal.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Angina 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 inappropriate treatment., Regulatory: Non-compliance with coding guidelines., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Always specify angina type., Use detailed clinical notes.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with specificity requirements., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Specify the type of angina (stable, unstable) and document accordingly.
Impact
High audit risk due to lack of specificity.
Mitigation Strategy
Ensure documentation specifies angina type and clinical findings.
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.
