Current wording:

"This implementation guide (IG) defines an exchange mechanism for providers to request and receive cost information from a payer regarding a service or item."

Doesn't this IG really cover coverage/benefit information rather than cost? Cost is defined by the provider. The payer specifies how much of that is covered as well as any cost sharing information.

Consider changing to:

"This implementation guide (IG) defines an exchange mechanism for providers to request and receive coverage information from a payer regarding a service or item."

This first paragraph also seems to read backward. The starting event is the creation and transmission of the GFE by the provide which in turn results in an AEOB. The paragraph reads as though the GFE is an afterthought that happens to also be included in the AEOB, but not as the request itself. Also, the profile does not specify that the GFE is returned in the AEOB bundle. Is that the expectation? If so, it needs to be included in the profile. (is this the gfeReference extension in AEOB?)
