Employer insurance "member services" moving from Anthem to Included Health (Grand Rounds). What is this? Should I be worried?

I work at a large multinational who historically its employees well. We have awesome Anthem insurance (BlueCard PPO network with HDHP and non-HDHP options). We’re self-insured, if it matters.

We see claims and EOBs through an Anthem insurance portal, for the most part things just work. When I have questions about coverage or want to dispute something, I can use Anthem’s 24/7 live chat support and the quality of my interactions has always been high.

My employer just told us that as of next year, all member services are moving from Anthem to something named Included Health (formerly Grand Rounds): https://includedhealth.com/employers/. They say this includes clinical and non-clinical support, but it seems Anthem is still involved on the backend.

It seems like IH tries to offer sort of quasi health care concierge + “we will help you review/wrangle your claims and deal with providers, so you don’t have to” type deal. This sounds nice in theory, but I have no idea what it means in practice or whether it’s just marketing bluster and a well-disguised cost cutting move, e.g. replacing higher-quality Anthem member support with some “we use automation and machine learning to reduce the employer’s costs” third party vendor who may be limited in their abilities, or have an alternate agenda.

Has anyone used Included Health/Grand Rounds in this capacity, or had health insurance with similar separation between the member services and the insurer themselves? Is this normal, and what should I expect?

I would love to better understand the nature of the relationship between Anthem and Included Health (and my employer) and, if this sort of relationship is common, how I can learn more about the roles and obligations of each.

Thanks!
