I work in a multiple MD practice which is not a corporation. How do I handle billings with regards to a Tax ID as each physician uses its own?
The answer is different based on whether you are a salaried employee (W-2) or whether you are an independent contractor. If you are a W-2 employee, and you work with all three physicians, you would use the appropriate physician’s tax ID when you work with them and they each would need to be listed as your supervising physician. You should have your own Medicare Number, which you can get by contacting Blue Cross/Blue Shield of South Dakota 800-326-0238. If you are an independent contractor, then you need your own tax ID (W-9). Some insurance carriers require that you have your own number. Have your office check. See if they credential PAs; if so, get your own number . You should have your own Medicare Number, which you can get by contacting Blue Cross/Blue Shield of South Dakota 800-326-0238.
