Could someone please help me here. A patient is on a statin for hyperlipidemia. Because of this he will need his liver function test monitored. How should the diagnosis for LFT's be coded? I would have used V58.69, 272.2 but now see that V58.69 is secondary only code. Some other articles state to use V58.83 as prim but this is not a medicare covered code for LFT's in NY state. Thanks
