Initial consultation 

The practice is currently on a wait-list, new consultations are limited to direct referrals by collaborating physicians or existing patients of the practice.  

 To be added to the wait list, please call or text Dr Johnson directly at 312-343-4342 and include your full name, address, email, phone number and date of birth (serious inquiries only). These demographic details are essential to creating your electronic health record/chart. Once your chart is created, you will receive an email invitation from the practice portal to log in and complete an extensive health questionnaire which will address your health goals, past medical history and lifestyle.  

When there is opening for a new appointment, this is the process of establishing your consultation: 

1.  Dr Johnson will submit your lab order to Quest and call you to confirm your appointments. 

2. You will schedule a lab draw at Quest Labs, a morning appointment before 9am. You will need to fast (no food, but drink plenty of water) for 12 hours prior to the lab draw. You can schedule the appointment at http://www.questdiagnostics.com. The lab order will be on the portal and is submitted to Quest directly, please print a copy of the lab order and bring the order to your appointment at Quest. The labs are included with the consultation.

3. All previous medical records can be sent to the office by secure fax (312-736-9556),   or messaging Dr Johnson on the portal which allows PDF attachments. You can also send Dr Johnson your username/password for other health portals, she will  review your previous labs and include the data in your biomarker panel reports.  
                                                        
4. You will meet Dr Johnson at the Chicago area or Naples, FL office for a 2 hour + consultation to review labs and collect your body composition data.   At the time of consultation,  a personalized “Precision Plan” is created with each patient. 
5. The fee for the consultation is $2k, payable at the time of the lab draw. HSA or FSA funds can be used towards the consultation fee. The date of the consultation is usually about two weeks after the date of your lab draw.
6. After the initial consultation, you may opt to join the monthly membership practice which includes all follow-up office visits, texting/emailing/coaching support, prescription services and quarterly labs. The monthly membership fee is $400, payable on a month-month basis. Alternatively, you can follow-up  “as needed” to track your progress on the plan, these appointments are usually booked with 4-6 week advance notice. These appointments are  billed at an hourly rate of $250 and follow-up labs are billed to insurance.

Frequently Asked Questions

Who are typical clients of the program? Do I have to be a certain age? Do I have to live in the Chicago area?

Typical clients are highly motivated to look and feel their very best, at EVERY age. Dr Johnson has clients that live on each coast of the United States since there are so few physicians who offer consultations with a focus on precision medical care. Lab tests are coordinated with partner lab testing sites that are located all over the country. Clients usually visit the office annually and often quarterly, depending on schedules and client preference. Dr Johnson is reached directly by her clients, direct messaging via cellphone, email or the patient portal.

 

    How do I get started?
    Consultations start with an inquiry to the office. Send a text, email or make a phone call directly to Dr Johnson. She can be reached at 312-343-4342 and by email at catherinejohnsonmd@yahoo.com. She will review your concerns and objectives for a precision health analysis.

    You will complete a comprehensive personal health and lifestyle survey with a detailed review of your family and medical history. Appointments and laboratory testing will be arranged based on your availability. Scheduling is very flexible and based on mutually agreeable times between Dr Johnson and her clients. The lifestyle of busy professionals and the needs of a busy family are understood. Early mornings, evenings and weekend appointments are all options for your visits with Dr Johnson.

    Is Medical Insurance accepted?

    No, Precision Medical Care LLC is not credentialed as an in-network provider with private health insurers, Medicare or Medicaid. When working in the emergency department, Dr Johnson sees all patients regardless of their health insurance status. In private practice, Dr. Johnson chooses to spend her time directly with patients as much as possible. For this reason, there is no administrative time designated for insurance paperwork. The private practice is a cash-based practice. Credit cards are accepted for payment. Health Savings Accounts and funds should be used for payments to maximize tax savings, when applicable.

    For all other questions, please call, text or email Dr Johnson directly. 312-343-4342 (cell) catherinejohnsonmd@yahoo.com (email)
