Most insurers have a website where you can estimate costs and find providers. If you want to know about costs, ask the provider to estimate the cost as they will know the codes to bill it as.

The main problems are the incentives. Providers and insurance are fighting each other and the customers to cut their own costs and retain/recover as much money as possible. But yes, if you could overcome these fights while improving the billing and reimbursement efficiency then it would save a ton of money.
