Just curious how other people are assiging the diagnosis code for elevated liver functions? There are two codes 790.6 and 794.8; I don't know what the difference is in these two diagnosis, however, 794.8 meets medical necessity for Medicare, 790.6 does not. So I am curious what other coders are doing. We see this diagnosis frequently.

Thanks!

Oh this has been such a peave of mine I have always been told to use 790.6 but I have used 794.8 because it says abnormal function study of the liver. I understand your pain because no one wants to pay for 790.6.

So you all have been told not to use 794.8? This is what my supervisor told me to use -- and so I have been using 794.8 ever since. :confused:

794.8 is specific to liver function SCANS, not metabolic liver function (which test results will demonstrate). That being the case, unless you're doing nuclear medicine scans, you shouldn't be using 794.8.
