Renal Coding Considerations (old)

Data Integrity Rules

• If CRF (351 00) is coded as comorbid then ARF (350 **) must not be coded as Admit/Acquired.

• • Exception: if Renal Transplant (805 00) is also coded as a comorbid
    • So how do you check for patients with renal transplant in comorbid, done many years ago, but patient has been receiving outpatient dialysis for some time because of transplant failure prior to admission? TOstryzniuk 16:22, 8 October 2008 (CDT)

Template:Discussion

• • discussion Tina/Julie: 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
    • Tina is correct, code is either 351 or 350 in all if continuous admission.TOstryzniuk 16:22, 8 October 2008 (CDT)
  • If a patient is newly admitted to the hospital with ARF (350 00 first time dialysis ever) and moves between units (continuous admission) and he is still requiring dialysis , he remains as ARF (350 -00) until he is discharged from from the hospital.
  • If this same patient is readmitted back to the hospital from the community, and was on outpatient dialysis, then new encounter to the hospital system, comorbid code is not CRF (351 00). TOstryzniuk 16:22, 8 October 2008 (CDT)

• If CRF (351 00) is coded as comorbid then Acute Renal Insufficiency (364 00) must not appear in Admit/Acquired codes

Both of these rules are currently checked at the main office and result in calls for clarification from Pagasa if broken.
