Your rights and protections against surprise medical bills

Insurance listings are subject to change without prior notice. Please call your physician's office or your health or insurance plan to verify coverage information prior to scheduling your visit or procedure. Not all members participating in contracted networks have "in network" access. In network participation may change from time to time without prior notice. Independent providers (which could include, for example only, anesthesiologists, radiologists, pathologists, emergency medicine physicians, advance practice professionals, and other independent providers of health care services) may deliver part of your care, and such providers may be considered out-of-network on your health and insurance plans even if the Facility may be considered in network. If you desire additional information as to the providers who may be involved in providing your care, you can either ask your treating provider (who may know some of the specialists or groups who could be involved) or you can request a list of Facility-based physician groups by calling the following toll free number: (877) 810-0372. This list is updated annually and is subject to change without prior notice.

Dr Theo thoroughly reviewed my case and provided the first plausible explanation for my knee pain. She asked if she could remove my PICC because she felt the IV antibiotics were not needed. Thus my need for home Healthcare was eliminated.

I am in my 70's and have had to see a great amount of Doctots through the years and can honestly say that my recent first visit with Dr. Theoktisto was the most comfortable, relaxed and very confident visit I have had with any Doctor. She quickly made me feel that she knew very well everything she needed to in order to help me recover from what I have being In her care.
