0.000What This Code Means
A tear in the inner lining of the renal artery that supplies the kidney, which can cause flank pain and potentially affect kidney function.
Coding Tips
- •Specify laterality (right or left) when documented
- •May present with hypertension or flank pain; often discovered on imaging
Clinical Significance
Dissection of the renal artery is a critical vascular condition that can compromise kidney perfusion and lead to renal ischemia, renovascular hypertension, or renal failure. This condition may occur spontaneously, from trauma, or as a complication of fibromuscular dysplasia. It requires urgent evaluation and management to preserve renal function, reflecting significant clinical complexity.
Documentation Requirements
- ✓Imaging confirmation of renal artery dissection (CT angiography, magnetic resonance angiography, or renal arteriography)
- ✓Laterality — right, left, or bilateral renal artery involvement
- ✓Impact on renal function including creatinine levels and glomerular filtration rate
- ✓Etiology — spontaneous, traumatic, fibromuscular dysplasia, or iatrogenic
- ✓Treatment plan including anticoagulation, endovascular stenting, or surgical repair
- ✓Blood pressure monitoring and management of renovascular hypertension if present
Commonly Confused Codes
I77.70 — Dissection of unspecified artery: less specific; use I77.73 when renal artery is documentedI70.1 — Atherosclerosis of renal artery: chronic atherosclerotic disease, not acute dissectionN28.0 — Ischemia and infarction of kidney: use for established renal ischemia as a sequelaI15.0 — Renovascular hypertension: may be secondary to the dissection, code additionally
