'''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.

* 1 and 2.) If Code 351 (CRF) in Comorbid then Code 350 (ARF newly dialyzed), 364(ARF) should not appear in Admit/ Acquired codes.
* A patient who has been receiving outpatient dialysis treatments '''recently''' prior to hospitalization is considered to be in CRF.
'''unless'''
* A patient who is '''not currently''' in a dialysis treatment program should '''not''' be considered to be in CRF.
If Code 805 (Renal Transplant) appeared in Comorbid along with code 351 then Code 350 can appear in Admit/ Acquired.
* A patient with an intact kidney transplant who is not being dialyzed should '''not''' be coded as CRF
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.


See '''[[Renal Coding Considerations (old)]] and [[ICD10 Guideline for Renal Coding]]''' because there are a number of coding rules related to renal diagnoses.

  • A patient who has been receiving outpatient dialysis treatments recently prior to hospitalization is considered to be in CRF.
  • A patient who is not currently in a dialysis treatment program should not be considered to be in CRF.
  • A patient with an intact kidney transplant who is not being dialyzed should not be coded as CRF

See Renal Coding Considerations (old) and ICD10 Guideline for Renal Coding because there are a number of coding rules related to renal diagnoses.
