This is certainly true to an extent, but it ignores some big problems with fee for service. The biggest one is that incentives between patients and providers are not aligned, which means more than 10% of healthcare provided in the US is wasteful stuff the provider knows is unnecessary but prescribes anyway because it makes them money. There are real opportunities to save money without making outcomes worse, in fact, if we stop doing useless stuff that leaves more time to treat people with real issues.
