Two Different Charge Masters
I think you are talking about different chargemasters. Laq, I think you are talking about an ED physician fee schedule. And you are right that supplies are not separately billible. There are different approaches to ED physician fee schedules. Many use RBRVS values with a conversion factor that is at some multiple of the CMS CF. Others will look at various payer payments, competitior info etc to come up with fees.
Val. Developing a hospital CDM is a very specialized field. But I believe many of the supplies etc are set at cost plus. The key to the ED facility CDM is that all billible services, procedures, infusions, injections, meds etc are in the CDM and priced out so they are billed when appropraitte. As to the Levels, the CMS fee schedule is sometimes used as a basis, with fees set at a percentage above Medicare reimbursement. But as I said hospital cdms are a specialized field and there should be someone at your facility that can help you.
