| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I25.10 | Atherosclerotic heart disease of native coronary artery without angina pectoris | Use when coronary artery disease is present without angina symptoms. |
|
| I25.110 | Atherosclerotic heart disease of native coronary artery with unstable angina pectoris | Use when CAD is present with documented unstable 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.

Primary ICD-10-CM Codes for ischemic heart disease
Decision Criteria
clinical Criteria
- Coronary artery disease confirmed by angiography without angina symptoms.
Applicable To
- Coronary artery disease without angina
Excludes
- Atherosclerotic heart disease with angina pectoris (I25.11-)
Clinical Validation Requirements
- Coronary angiography showing ≥70% stenosis
- Absence of angina symptoms
Code-Specific Risks
- Risk of underreporting angina if symptoms are not documented.
Coding Notes
- Ensure documentation specifies absence of angina symptoms.
I25.110 - Atherosclerotic heart disease of native coronary artery with unstable angina pectoris
Use when CAD is present with documented unstable angina.
Applicable To
- Coronary artery disease with unstable angina
Excludes
- Stable angina (I20.9)
Clinical Validation Requirements
- ECG changes (e.g., ST depression ≥1mm)
- Elevated troponin levels
Coding Notes
Ensure documentation includes ECG findings and troponin levels.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
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 Ischemic Heart Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I25.10.
Impact
Clinical: Leads to inadequate treatment planning., Regulatory: Non-compliance with documentation standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Use structured templates for documentation., Educate clinicians on documentation requirements.
Impact
Reimbursement: Incorrect coding can lead to reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation specifies the type of angina or absence thereof.
Impact
Inadequate documentation of angina type can lead to audit issues.
Mitigation Strategy
Implement documentation audits and clinician 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.
