| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I70.0 | Atherosclerosis of aorta | Use when atherosclerosis is confirmed in the aorta without acute complications. |
|
| I70.23- | Atherosclerosis of native arteries of extremities with intermittent claudication | Use when claudication is present with iliac artery atherosclerosis. |

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 aortoiliac atherosclerosis
Decision Criteria
clinical Criteria
- Imaging confirms aortic plaque
coding Criteria
- No acute complications present
Applicable To
- Atherosclerosis of abdominal aorta
- Atherosclerosis of thoracic aorta
Excludes
- Aortic aneurysm (I71.-)
Clinical Validation Requirements
- Imaging report confirming plaque in the aorta
- Absence of acute complications like aneurysm
Code-Specific Risks
- Confusion with aneurysm codes
- Omitting imaging confirmation
Coding Notes
- Ensure imaging confirms atherosclerosis without acute complications.
I70.23- - Atherosclerosis of native arteries of extremities with intermittent claudication
Use when claudication is present with iliac artery atherosclerosis.
Applicable To
- Atherosclerosis of iliac arteries with claudication
Excludes
- Peripheral vascular disease, unspecified (I73.9)
Clinical Validation Requirements
- Documentation of claudication symptoms
- Imaging showing iliac artery involvement
Coding Notes
Specify laterality and document claudication distance.
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 Aortoiliac Atherosclerosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I70.0.
Impact
Clinical: Inaccurate patient records, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Train staff on documentation requirements, Use templates with prompts for laterality
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Use I70.0 and I70.2- for chronic atherosclerosis without acute thrombosis.
Impact
Lack of specificity can lead to incorrect coding.
Mitigation Strategy
Ensure detailed documentation of vessel involvement and 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.
