Code Comparison: When to Use Each Code
Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I70.21 | Atherosclerosis of native arteries of extremities with intermittent claudication | Use when documentation specifies atherosclerosis with claudication in native arteries. |
|
| E11.51 | Type 2 diabetes mellitus with diabetic peripheral angiopathy without gangrene | Use when diabetes is documented with peripheral angiopathy. |

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 arteriosclerosis
Decision Criteria
documentation Criteria
- Document laterality and claudication
Applicable To
- Peripheral artery disease with claudication
Excludes
- Atherosclerosis of bypass grafts
Clinical Validation Requirements
- Ankle-brachial index (ABI) ≤0.9
- Angiogram showing ≥50% stenosis
Code-Specific Risks
- Misclassification if laterality is not documented
Coding Notes
- Ensure documentation specifies laterality and presence of claudication.
E11.51 - Type 2 diabetes mellitus with diabetic peripheral angiopathy without gangrene
Use when diabetes is documented with peripheral angiopathy.
Applicable To
- Diabetic peripheral vascular disease
Excludes
- Diabetic peripheral angiopathy with gangrene
Clinical Validation Requirements
- HbA1c >6.5%
- Doppler evidence of arterial insufficiency
Coding Notes
Document the relationship between diabetes and peripheral angiopathy.
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 Arteriosclerosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I70.21.
Impact
Clinical: May lead to inappropriate treatment, Regulatory: Non-compliance with coding standards, Financial: Potential for denied claims
Mitigation Strategy
Ensure clear documentation of diabetes complications, Use templates to guide documentation
Impact
Reimbursement: May lead to lower reimbursement rates, Compliance: Non-compliance with coding guidelines, Data Quality: Decreases accuracy of patient records
Mitigation Strategy
Use E11.51 with I70 codes for specificity
Impact
Use of unspecified codes can lead to audits
Mitigation Strategy
Ensure documentation supports specific code selection
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.
