Wiki Elevated GFR Level

[ruthan]

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

"Glomerular filtration rate (GFR) is the best overall index of kidney function"

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