Acute Renal Failure

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.

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.

There are a number of coding rules related to renal diagnoses, centralized info about them is in Renal Coding Considerations.
