| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K55.1 | Chronic vascular disorders of intestine | Use when chronic symptoms and imaging confirm SMA stenosis. |
|
| I77.1 | Stenosis of superior mesenteric artery | Use to specify the vascular cause of mesenteric ischemia. |

K55.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Superior Mesenteric Artery Stenosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K55.1.
Impact
Clinical: Misdiagnosis of chronic vs. acute conditions., Regulatory: Non-compliance with coding guidelines., Financial: Potential claim denials.
Mitigation Strategy
Ensure imaging is reviewed and documented., Use templates to prompt for imaging details.
Impact
Reimbursement: May lead to denied claims due to lack of specificity., Compliance: Risk of audit failure due to insufficient documentation., Data Quality: Inaccurate data on chronic conditions.
Mitigation Strategy
Ensure documentation includes chronicity and imaging findings.
Impact
Failure to document chronic symptoms may trigger audits.
Mitigation Strategy
Use templates to ensure chronicity is documented.
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.
