You can, designate the Healthcare Business Monthly magazines, to go toward a specific credential. You would select the "Edit" link for each CEU you want to change, click 'Save' on the next screen, and then scroll down and switch the designation on the final screen and click 'Save' again.I signed up for the yearly webinar subscription from AAPC. The good news is they have a wealth of webinars that will get you your CEU's in no time, and they're great material.
The bad news is that I keep adding them to my CEU tracker, and for some reason they are counting towards my CPC but not my CPMA. Not sure why. Even the ones that say specifically that they are certified for CPMA CEU's. Got my CEMC ones without an issue and my CPC ones no problem.... but still says 0 for my CPMA.
I just learned weeks ago that to be able to distribute your earned CEU to your correct credential/s, you can hit the edit button, hit save, then it will let you post your CEU to the CPC core or to the specialty, CPMA etc. Hope this helps.
