| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I25.10 | Atherosclerotic heart disease of native coronary artery without angina pectoris | Use when atherosclerosis is present in coronary arteries without angina symptoms. |
|
| I70.2 | Atherosclerosis of native arteries of extremities | Use for atherosclerosis affecting extremities, confirmed by clinical tests. |

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

Decision Criteria
clinical Criteria
- No angina symptoms present
documentation Criteria
- EKG or stress test results available
Applicable To
- Coronary artery disease without angina
Excludes
- Angina pectoris (I20.-)
Clinical Validation Requirements
- EKG or stress test showing no ischemic changes
- Patient history confirming absence of angina
Code-Specific Risks
- Misclassification if angina is present but not documented
Coding Notes
- Ensure documentation clearly states the absence of angina.
I70.2 - Atherosclerosis of native arteries of extremities
Use for atherosclerosis affecting extremities, confirmed by clinical tests.
Applicable To
- Peripheral artery disease
Excludes
- Diabetic peripheral angiopathy (E11.51)
Clinical Validation Requirements
- Ankle-brachial index ≤ 0.9
- Imaging studies confirming arterial narrowing
Coding Notes
Document laterality and any associated symptoms or complications.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

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 Atherosclerotic 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: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials or reduced reimbursement.
Mitigation Strategy
Always specify if angina is stable or unstable., Use clinical notes to detail symptoms.
Impact
Reimbursement: May lead to incorrect DRG assignment affecting reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation explicitly states the absence of angina symptoms.
Impact
Reimbursement: Potential for denied claims due to lack of specificity., Compliance: Violation of coding specificity requirements., Data Quality: Inadequate data for clinical decision-making.
Mitigation Strategy
Always document and code the specific extremity affected.
Impact
Lack of specificity in coding can lead to audit flags.
Mitigation Strategy
Ensure all documentation includes laterality and specific symptoms.
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.
