Its a good question focusing on Facets functionality.
To reply to that, we have seen a lot of modifications to Facets application off late with “real-time” updates being main focus. For instance, having the real time accumulator synchronization implemented as part of the previous build.
However, the latest build(version 5.40) do not handle Pharmacy claims adjudication as such and as far as shadow accumulator functionality, the application do provide a place holder for Shadow accumulator processed by any external vendor. But this value is not applied in any Facets logic.
So I believe there is lot of scope in implementing the Pharmacy Claims adjudication process in Facets. Currently this is being taken care by TPA. Facets will receive files from TPA and only the accumulator value is being loaded into Facets.
Hope this was helpful. Will keep you posted once we come across any information.
