Complete code families applicable to Arterial Occlusive Disease
I70.2-I70.7Primary Range
Atherosclerosis of arteries
This range covers atherosclerosis affecting various arteries, including those in the extremities, which is central to arterial occlusive disease.
Occlusion and stenosis of precerebral and cerebral arteries
This range includes codes for stenosis and occlusion of carotid and vertebral arteries, relevant for cerebral arterial occlusive conditions.
Peripheral vascular disease, unspecified
This code is used when peripheral vascular disease is documented without further specification.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I70.2 | Atherosclerosis of native arteries of the extremities | Use when atherosclerosis of native arteries in the extremities is confirmed by imaging or clinical tests. |
|
| I65.2 | Occlusion and stenosis of carotid artery | Use for confirmed stenosis or occlusion of carotid arteries. |

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 arterial occlusive disease
Decision Criteria
clinical Criteria
- Presence of claudication or rest pain with documented stenosis
documentation Criteria
- Explicit mention of 'native artery' in medical records
Applicable To
- Atherosclerosis of native arteries of the legs
Excludes
- Atherosclerosis of bypass grafts
- Atherosclerosis of coronary arteries
Clinical Validation Requirements
- ABI ≤0.9
- Angiography showing ≥50% stenosis
Code-Specific Risks
- Misclassification if ABI is not documented
- Confusion with I73.9 if not specified
Coding Notes
- Ensure documentation specifies 'native artery' to avoid confusion with graft codes.
I65.2 - Occlusion and stenosis of carotid artery
Use for confirmed stenosis or occlusion of carotid arteries.
Applicable To
- Stenosis of carotid artery
Excludes
- Atherosclerosis of coronary arteries
Clinical Validation Requirements
- Carotid duplex ultrasound showing ≥70% stenosis
Coding Notes
Ensure imaging results are documented to support coding.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Arterial Occlusive Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I70.2.
Impact
Clinical: May affect treatment decisions., Regulatory: Non-compliance with coding guidelines., Financial: Potential loss of risk adjustment points.
Mitigation Strategy
Always check for diabetes in vascular patients, Link diabetes to vascular conditions when applicable
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with specificity requirements., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Use I70.2__ codes when atherosclerosis is confirmed.
Impact
Risk of audits due to lack of specificity in coding arterial occlusive disease.
Mitigation Strategy
Ensure detailed documentation and use of specific codes.
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.
