Acute Renal Failure

Guideline

• newly dialyzed - which means new dialysis started during this hospital admission for a patient that was not on out patient dialysis prior to current hospital admission.

• Patient does not have CRF - Chronic Renal Failure

• The ARF diagnosis only applies if patients actually receive dialysis or CRRT at that location. If a pt does not receive dialysis you can code ARI or ATN instead. See Renal Coding Considerations
• Acute renal failure can have a pre-renal source or a post-renal source. Pre-renal sources are most common like shock states, low perfusion, toxic causes, etc. Post-renal causes refer to obstructive causes of renal failure like obstructive nephropathy from blocked ureter for example.
