Hi, I'm trying to bill for 3 separate psychotherapy services for one patient on one DOS:
90791
90846
90834
Each were at separate times (which I know isn't able to be marked on a HCFA!) by a licensed psychologist (so not an MD, no medication-related services).
90791 was accepted, but the other 2 claims came back as denied, with error messages stating that the codes have a unbundled relationship with one another.
All 3 services were medically necessary.
The insurance company didn't know what to tell me, other than I could try to add "modifiers." This is all new to me, and I can't figure out what modifiers to use.
Anyone have any suggestions?
Thanks in advance!
