ICD-9 Codes

I need the list of insurance codes for blood labs. Think VitaLady had one but I can't find it now. I remember being told to make sure the insurance does NOT use "Surgical Malabsorbtion" since some policies do not cover anything related to WLS.   I have Blue Shield HMO and want to make sure its gets paid. They have paid it before but with all the talk about the insurance reforms I would like to get my PCP to use the code thats "more acceptable."  Can those of you who have great success getting your labs paid post the ICD-9 codes used for insurance coverage?
