If you have an Advance Directive or living will, we will make a copy of that. You will be given a copy of our Privacy Practices. If you have pre-registered, you will be given a copy of your demographic and insurance information to review and approve.

Medicare Patients

We are required by federal law to ask you questions regarding other payment sources. Although you may have answered these in the past on other visits, we have to ask the questions each time you come for treatment except for recurring treatments 90 days. For patients spending the night, you will also be given a copy of your Medicare Rights.
