The price transparency requirement I linked above applies to health plans, not providers. (There's a separate price transparency requirement for hospitals but it's less useful to consumers with health plan coverage.)
I'm not sure what you mean about different codes for the same thing. The health plan MRFs all use the same CPT/HCPCS codes. Each code has a unique meaning.
Health plan member portals also have online shopping tools where you can do price comparisons for every network provider within a certain distance. So what you're asking for pretty much already exists, although many consumers aren't aware of this.
