| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I77.1 | Stricture of artery | Use when imaging confirms stenosis and symptoms are present. |
|
| I70.8 | Atherosclerosis of other arteries | Use when stenosis is confirmed to be atherosclerotic. |

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

Essential facts and insights about Subclavian Artery Stenosis
Primary ICD-10-CM Codes for subclavian artery stenosis
Decision Criteria
clinical Criteria
- Imaging confirms stenosis ≥50%
documentation Criteria
- Symptoms include arm claudication, pulse deficit, or blood pressure differential >15 mmHg
Applicable To
- Subclavian artery stenosis
Excludes
- Atherosclerosis of subclavian artery (I70.8)
Clinical Validation Requirements
- Imaging confirms stenosis ≥50%
- Symptoms include arm claudication, pulse deficit, or blood pressure differential >15 mmHg
Code-Specific Risks
- Incorrectly using I70.8 without proper documentation of atherosclerosis.
Coding Notes
- Ensure laterality is documented for accurate coding.
I70.8 - Atherosclerosis of other arteries
Use when stenosis is confirmed to be atherosclerotic.
Applicable To
- Atherosclerosis of subclavian artery
Excludes
- Non-atherosclerotic stenosis of subclavian artery (I77.1)
Clinical Validation Requirements
- Documentation explicitly states 'atherosclerotic stenosis'
- Imaging/lab confirmation (e.g., LDL >130 mg/dL)
Coding Notes
Ensure atherosclerotic nature is documented.
Ancillary Codes

G45.8Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Subclavian Artery Stenosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I77.1.
Impact
Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Fails to meet documentation standards., Financial: Potential for denied claims due to insufficient documentation.
Mitigation Strategy
Use specific clinical terms, Include detailed symptom descriptions
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data on patient records.
Mitigation Strategy
Query provider for etiology and provide LDL results.
Impact
Reimbursement: May affect DRG assignment and reimbursement., Compliance: Non-compliance with coding specificity requirements., Data Quality: Incomplete patient data.
Mitigation Strategy
Always document left/right for accurate coding.
Impact
Using I70.8 without confirming atherosclerotic etiology.
Mitigation Strategy
Require documentation of LDL levels and imaging confirmation.
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.
