    Question Elevated GFR Level

    AAPC: Back to School
    I am hoping that someone out there can shed some light on this topic. I am seeing lab orders come through with a Diagnosis of Elev. GFR, or Low GFR. I found Coding Clinic 4th Quarter 2005 Page 77-79, that describes this but what am I to be using for a Diagnosis Code for it: 585.9 or a Abn. Lab finding unspec. 796.4?

    Any help that someone could provide would be appreciated.

    794.4? abnormal renal function test

    794.4 is correct, it is the creatinine clearance
    in ICD-9, found under findings, abnormal.
