0.000What This Code Means
A blood clot that forms in the renal vein, which drains blood from the kidney.
Coding Tips
- •Document whether the thrombosis is acute or chronic, and specify right, left, or bilateral involvement
- •Note associated conditions such as nephrotic syndrome, malignancy, or renal infarction
Clinical Significance
Renal vein thrombosis is a serious vascular condition that can lead to kidney damage, nephrotic syndrome exacerbation, and pulmonary embolism if the clot propagates. It is often associated with underlying hypercoagulable states, malignancy, or nephrotic syndrome, making it an important marker of disease complexity. Proper documentation and coding ensure accurate risk stratification for patients requiring anticoagulation and nephrology follow-up.
Documentation Requirements
- ✓Clinical diagnosis of renal vein thrombosis documented by the treating provider
- ✓Imaging confirmation (CT venography, MR venography, or renal Doppler) showing renal vein occlusion
- ✓Documentation of laterality (right, left, or bilateral) when determinable
- ✓Documentation of acuity (acute vs. chronic presentation)
- ✓Assessment of underlying cause (nephrotic syndrome, malignancy, hypercoagulable state)
- ✓Current treatment plan including anticoagulation and nephrology follow-up
