90 Degree Benefits

Are any of you billing 90 Degree Benefits for your clients? On the 90 Degree website it says "If you send EDI claims to Change Healthcare, please update the platform to Optum Healthcare." We reached out to Procentive who told us they only use Availity for electronic submissions and there is not an option to use a different clearing house. What are others doing in this situation? It seems to me like we shouldn't have to submit paper claims.
