Frequently Asked Questions
Is there any insurance coverage for your services?
We are not contracted with any insurance companies.
What past medical history and documentation is required before I schedule an appointment?
The New Patient Intake Form is the only required document. Past medical records and labs are not mandatory, though you are welcome to bring any documentation or have it sent to our office prior to your first visit. During your initial visit, we will discuss which past medical workup may be most helpful.
I have not been able to establish a diagnosis with my past providers. How can Dr. Mitchell help me?
The absence of a concrete diagnosis does not limit access to treatment, especially when you are symptomatic. Many treatments for autoimmune diseases overlap. For example, medications like hydroxychloroquine or methotrexateare often used for multiple autoimmune conditions. Often, treating comorbidities outside of the primary autoimmune disease reduces inflammation enough to improve your primary concern. See the FAQ on holistic approach.
Will my case require medications?
Most patients do require prescription medications to make progress. Your care plan, however, is not limited to medications only. For some patients, if minimal disease activity is achieved and maintained for 6–12 months, guidance is provided for tapering or discontinuing medicines.
Should I continue care with my present rheumatologist?
In some cases, continued care with your current rheumatologist is strongly advised, especially if you have: Autoimmune-associated organ-threatening disease (e.g., interstitial lung disease, lupus nephritis) History of multiple blood clots, heart attacks, or strokes. In other cases, your care plan will be discussed during your first visit.
How often do I need to be seen?
Initial visits: Every 4 to 12 weeks Once stable: Every 6 to 12 months
What about continuing care with other specialists or naturopaths?
This is encouraged. Dr. Mitchell collaborates with other providers and frequently refers patients to non-rheumatology specialists when appropriate.
What is the extent of the holistic approach Dr. Mitchell takes?
Dr. Mitchell’s philosophy considers the body as a whole, not just the primary disease. It is common for patients with rheumatologic conditions to have multiple comorbidities, such as: Autoimmune thyroid disease Polycystic ovarian syndrome Allergies / MCAS Weight gain Vitamin deficiencies Post-COVID-related issues Addressing all relevant comorbidities helps optimize care for the patient’s primary concern.
