Chronic Renal Failure is coded for any patient who is on chronic dialysis due to kidney failure. This code can only be used for comorbids. For newly dialyzed patients use the ARF - Acute Renal Failure codes.
Data Integrity Rules
See the data integrity check related to this code at "CRF vs ARF, ARI, Renal Transplant".
- 1 and 2.) If Code 351 (CRF) in Comorbid then Code 350 (ARF newly dialyzed), 364(ARF) should not appear in Admit/ Acquired codes.
unless If Code 805 (Renal Transplant) appeared in Comorbid along with code 351 then Code 350 can appear in Admit/ Acquired. i.e. find any for whom ARF and CRF appear together, except if there is 805; Since B is a subset of A that invalidates the difference between the two I only generated B
- 3.) If having more than 1 encounter (i.e.: continuous or same hospital admission), then Codes 350 and 351 should not appear together in at least one of the encounters. Why should they occur together in any? That happens and definitely that is encoding error. Ideally, should be all 350 in all encounters or all 351 in all encounters. Umm… ideally? So, flag it or not? Flag it
So, if during the same hospital or even ward stay, someone goes from ARF to CRF, that should be acceptable, right. (Unless we don’t code a brand new como as a como…). However, should a CRF patient ever become ARF again? I guess they would have to loose their CRF status, right? Now, I guess that could happen with a kidney transplant… are there other reasons one would loose CRF? How about this: List anyone who has (a como 350-CRF with the same or greater encounter ID as a adm/compl 351-ARF) more often than (dx 805 - kidney transplants +1) across all PHIN occurrences. Query Not Yet Generated – will do with other multiple encounter ones.
