I have similar support issue with ACPM. I contacted AC general support and was told that I should direct my ACPM questions to ACPM team. However I have not heard any response from ACPM team for more than 2 weeks despite my multiple emails and phone calls.

The critical issues I am experiencing are as follows:

1. ACPM apparently does not receive all ERA/EOB from clearing house ClaimRemedi. Therefor A/R management monitor function such as aging A/R report and Unpaid Claims are not very useful. ACPM recommends user to run this report periodically. We have not received any Harvard Pilgrim ERAs despite getting HP electronic deposit in bank. Therefore it is important to reconcile your ERA in ACPM with your check/bank payment received.
2. Unable to submit the claim which requires prior authorization number in HCFA 1500 box 23. It seems at this point we don't have good way to input the PA number. We have claims sitting there and wait to be submitted.
3. Unable to add referral number to the HCFA claim form. At this point, we are not able to submit the claims which require referral number.

I wonder anyone else has similar issue, anyway to work around?

Any inputs/suggestions are greatly appreciated.
