What does the provider want to supply as DME? Sleep apnea machines, for instance? You do not bill CPT codes to DME, you bill the appropriate HCPCS code, with any necessary modifiers, for the supply/equipment that is being dispensed, using POS 12, for Home. Any related office visit would go to regular Medicare for that date of service, with POS 11, for office.
What do you mean by DME facility? Will the provider not be dispensing the items directly from his primary practice location?
My provider is a podiatrist, and is also a DME supplier, for splints, braces, etc. We have a group NPI for our practice, and she has an individual NPI. When we applied to be a supplier, we used the group NPI. Her individual NPI goes on the claims as the rendering provider/ordering provider, and the group NPI is used for service location and billing location.
