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.

When a pt starts out in a community hospital and is given a diagnosis of ARF by the doctors, please do not code ARF unless dialysis is started there. Code ATN or ARI instead. If the pt is transferred to another center to start dialysis, the collector there will code ARF. When a pt with ARF from a tertiary hospital is transferred to a community hospital and no dialysis is needed there, the data collectors at the community hospital should not be coding ARF because the renal failure is resolving. They can code ARI. This is my understanding. Trish please let me know if this is the way you also see it. I believe the above information for integrity checks is wrong. --LKolesar 13:41, 20 July 2011 (CDT)

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