I'm not really sure what you are looking for. Yes, you can use mid-levels to help with inpatient consults. You just have to hire, train and pay 'em.
If you are looking to do "rehab placement" consults, there really isn't too much to it. It is literally deciding, do they need at least 2 therapy disciplines and have some medical complexity and can tolerate therapy? Which is also what the medical director does when reading the pre-admission screen.
If you are looking for someone to do peer-to-peers for IRF, I find it is mostly falling on the primary team anymore to complete. I used to get consulted after IRF denial to complete peer-to-peer, but insurance started requesting primary team only. But I am not doing consults currently.
If you are looking for "medical management" consults, then you may want to do them yourself or let the NP's do follow ups only. I agree with the above poster.
We have someone doing rehab placement consults in my group. To be honest, I never really read their notes because all they ever say is something about meeting IRF criteria and should be admitted, blah, blah, blah.
