NPs are considered providers, so they can bill insurance for services like MDs. I honestly have no idea how NPs are compensated in retail chains.
I doubt even if pharmacists got classified as providers that chains would give us a portion. We already bill for immunizations since protocols with MDs are set up to allow us to do so, and I don't know of any chain that gives RPhs a cut of each one done. We still typically make more than an NP anyway or anyone in general, for that matter, so I can't complain too much.
The bulk of our economic benefit to chains or hospitals to justify our employment will always be dispensing meds, no matter what faculty/academics will try to say to the contrary. This stuff is just window dressing.
Pharmacy orgs would be much better served fighting for improved working conditions and doing something about dropping insurance reimbursement first rather than this stuff.
