CPT Q Codes for Ventricular Assist Device

We are having problems with getting claims denied with the Q codes.

I am copying and pasting what I had seen on an earlier submission - Q codes are for Medicare claims only. These codes are used to identify professional healthcare procedures and services that would otherwise be coded in CPT but for which there are no CPT codes. These are temporary codes.

Are the Q codes still listed as temporary? Specifically Q0481, 0484, 0489, 0496, 0497, 0505 and there may be a few more that I am not listing but ANY help with this would be appreciated!

If you need additional information, please let me know.
