| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I70.1 | Atherosclerosis of renal artery | Use when renal artery stenosis is due to atherosclerosis. |
|
| Q27.1 | Congenital stenosis of renal artery | Use when renal artery stenosis is due to fibromuscular dysplasia. |

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

I12.9Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Renal Artery Stenosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I70.1.
Impact
Clinical: Impacts treatment decisions and outcomes., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials or delays.
Mitigation Strategy
Always specify laterality in documentation, Use templates that prompt for laterality
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Verify the etiology of stenosis before coding.
Impact
Inadequate documentation of stenosis cause can lead to audit flags.
Mitigation Strategy
Ensure thorough documentation of diagnostic findings and etiology.
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.
