No. You get to be in control of your medical care - you have many options with DPC; if your schedule is busy you can talk to me about your issue on the phone, by text, or even email.
Gone are the days of your doctor "requiring" you to come in for an office visit just so the doctor could get adequately paid by the insurance company or Medicare.
If, however, you want an office visit, I can often schedule you for the same day or the next, and usually provide enough time to resolve the problem in one visit.  If it requires more visits, no problem - there is no extra fee, and no restrictions from insurance companies or Medicare on duration of visits or how many visits you can have to address a particular issue.
