The primary posting is for elevated liver enzyme(function) tests.
This term actually could refer to any one of a number of conditions, and does not necessarily indicate any specific disease.
Alanine transaminase, Aspartate transaminase (AST) Alkaline phosphatase, Lactate dehydrogenase (LDH) are the elevated Liver enzymes, indicating the liver is getting into damage. The transaminases group are the most commonest which are looked for as indicators of liver damage.
The most ideal and with more specificity would be ICD code is 790.4 and/790.5 as they depict the elevated liver enzyme status . The code 790.6 talks more of the metallic levels and minerals level which are not the indicators of liver damage.
It does not say about enzyme levels, where as, at least the codes 790.4 and 790.5 are dealing with elevated enzyme levels AST ALT LDH , alkaline phosphatase Phosphatase and pancreatic enzymes amylase and lipase.
I understand why you code the 790.6 because in the index 790.6 is given for LFT.
i feel some gray area in coding so.
elevated Liver enzymes are very important not only for Liver damage ,they are important to indicate other conditions like HELLP SYNDROME,infectious mononucleosis, fatty degenerations, certain medications, some coagulopathies, Liver and biliary dysfunctions and so on.
So the ELEVATED LIVER ENZYME STATUS is important hall mark for a variety of conditions think it need some more specification in diagnoses coding placement.
