KX Modifier

Hi, I got a denial from medicare (Texas) for CPT® codes 95903,95904,95934 "The procedure code is inconsistent with the modifer used, or required modifier is missing" when called representative of medicare they told us to bill with KX modifier.I dont understand why should we use modifier kx for nerve conduction studies. Can you please explain this?
Also i got denial for CPT® code 95886 as well from medicare "The related or qualifying service was not identified on this claim".
I billed 95903(8 units),95904(10 units),95934 (mod 50) and 95886(2 units) on this claim for which i received denial. There is no office visit billed...
Diagnosis used is 724.4

Can you please explain me where i am going wrong?????

re: KX Modifier

This is correct. Training and Competency-- Trailblazers requires the KX modifier for EMG/NCS to verify that the performing physician has met all criteria eligibility to perform testing. (May 1, 2012). You must also indicate the manufacturer and model number of the equipment used.
