0.450ESRDHCC 107 — Vascular Disease with Complications
0.000What This Code Means
Reduced blood flow to the kidney or death of kidney tissue due to blocked blood vessels, which can cause sudden loss of kidney function.
Coding Tips
- •Document the cause of ischemia (thrombosis, embolism, stenosis) when available for more complete coding
- •Distinguish between acute infarction and chronic ischemic changes based on clinical presentation and timing
Clinical Significance
Renal ischemia and infarction represents acute vascular compromise that can lead to permanent kidney damage and chronic kidney disease. This condition requires immediate intervention and carries significant morbidity risk, making it important for risk stratification and care planning.
Documentation Requirements
- ✓Evidence of acute or chronic renal artery occlusion
- ✓Imaging confirmation of renal infarction or ischemia
- ✓Laboratory evidence of acute kidney injury or dysfunction
- ✓Documentation of underlying vascular disease or embolic source
- ✓Assessment of bilateral vs unilateral involvement
- ✓Exclusion of other causes of acute kidney injury
- ✓Clinical presentation consistent with renal infarction
- ✓Treatment plan addressing vascular compromise
Excludes 1 — Do NOT code together
