services done by ARNP/MD pcodes 97530,97012,97032 no attached modifer billed to mcare replacement= AARP medicare complete UHC.. they denied the codes due to icd9 not supportive, rep asked me to rebill with a supportive icd9 code in re LCD's.. (I am new learning LCD's) .. I researched the LCD's, it shows payable dx 457.0, 457.1, 757.0. Now, I am really confused.. I have billed the above mentioned codes directly to medicare by the ARNP with GP modifer with dx's like 724.4, 724.4,722.52 and they have paid.
When I bill a medicare replacement should I use the GP modifer as well? need help
