Hi Mustang,
Oh you asked that dreaded question about how they arrived at the number. It is a very complex system which has been in place for many years now.
Medicare uses the RBRVS or resource-based relative value scale. For each procedure performed an RBRVS is assigned and takes into account the actual physician work, expense of the practice, and malpractice expense. These expenses are not physician specific, but are general expenses determined by HCFA, Healthcare Financing Administration or CMS.
The RBRVS is adjusted by the value of the procedures for various geographic regions. Say the same work performed in D.C. would have a higher value as if it were performed in S.C. where the cost of living is lower in S.C. vs D.C. A conversion factor that is adjusted annually is applied to the RBRVS to arrive at the amount of payment for the procedure.
What it boils down to is that Medicare's determination of the value of a procedure code is the Holy Grail for reimbursement throughout our healthcare system. Major insurance carriers base their reimbursement on the rates that Medicare sets. As I noted, the conversion factor is updated annually and therefore drives the change in the value of the procedure codes annually too. Medicare publishes the adjusted rates annually.
The fact that the Medicare rates are the Holy Grail of reimbursement is one of the many flaws in our healthcare system. The Medicare rates are extreemly low in comparison to the actual cost of operating a practice and when an insurance company negotiates their contracted rates based on the Medicare rates, the insurance companies normally are getting away with grand theft! But they do get away with it because they hide behind what Medicare has established.
Sorry if I go on and on. I used to have to deal with reimbursement in my former job and it still hits a nerve with me.
I hope that I have explained it in a nutshell. There is so much more to it though.
