Frequently Asked Questions

Functional medicine is an approach to healthcare that seeks to restore the proper functioning of the body by removing obstacles to health, replacing what the body needs, and balancing physiological pathways where necessary. Ideas like "root-cause resolution" communicate that functional practitioners "go deeper" into their patients' health history and attempt to incorporate more comprehensive data analysis. While traditional medical approaches use medications and procedures to stop something bad from happening, functional medicine looks for ways to promote health.

We work with all patients. As a family medicine physician, Dr. Coller is trained to provide care for all age groups, men, women, and children. 

Dr. Coller has had years of experience treating both acute and chronic illnesses. He has worked in the family practice setting, as well as in urgent care - online and in person. These experiences have provided a broad knowledge base for him to use as he cares for his patients. Even if he is not equipped to address an issue himself, Dr. Coller can guide his patients to where they can best receive the care they need.

As a functionally trained doctor, Dr. Coller has helped many patients with chronic conditions such as diabetes, heart disease, chronic fatigue, autoimmune issues, irritable bowel syndrome, SIBO, and other GI problems. He balances hormones, restores nutrient deficiencies, optimizes detox pathways, and more. 

Truly, the functional medicine approach provides a framework for empowering each person's body to find a path to healing and wellness. The 'disease' or 'diagnosis' that people carry is often simply the normal physiologic response to the underlying imbalances. When we correct those imbalances, the 'diseases' often resolve or go into remission. 

Precision Functional Medicine partners with Functional Health Professionals, LLC to provide Care Manager support for its patients. These Care Managers assist Dr. Coller's patients with a variety of things including understanding test pricing, troubleshooting lab and pharmacy issues, and helping patients have a smoother all-around patient experience. 

When asked to describe their doctors, most patients' first thoughts are rushed and distracted. 

At Precision Functional Medicine, we want our patients to think the opposite: present and focused. 

For this reason, we hold longer visits with our patients. Paradoxically, we find that having more time to think through our patients' cases results in more accurate diagnosing, more comprehensive treatment plans, and overall reduced healthcare costs for our patients!

Every patient is different, but functional medicine generally works best as an ongoing process rather than a single consultation.

New patients typically begin with two 60-minute visits to establish their history, baseline testing, and initial treatment plan.

After that, the frequency of follow-up depends on your goals, health concerns, and progress. Some patients prefer occasional individual visits, while others choose Continuing Care, which includes up to five flexible follow-up visits over 12 months.

Yes, of course! I am happy to incorporate the data that you have already collected into your treatment plan. 

An important thing to keep in mind, however, is that initial visits are not intended for extensive test review/interpretation. 

Although there may be time for reviewing some test results, first visits are a critical opportunity for Dr. Coller to get to know you and to do a proper intake & interview. As we say, "functional medicine physicians treat people, not test results." Therefore, it is important to understand that a proper interpretation and treatment plan can only be achieved after having taken the time to thoroughly understand your story. The results make much more sense in the context of your health history and timeline. 

New patients need enough time for a thorough history and initial assessment, so the first visit is 60 minutes.

New patients may either begin with the New Patient Starter, which includes two 60-minute visits, or schedule the initial 60-minute visit individually.

Once you are established, follow-up visits are generally 30 minutes. Shorter focused visits may occasionally be used when clinically appropriate.

"Primary Care" is a poorly defined phrase that requires some clarification.

Like other primary care offices, Precision Functional Medicine can be a 'first-line access point' into the medical system. We provide direct patient care, order labs, send prescriptions, provide referrals to specialists, and help you make sense of your overall health journey. 

As a mostly telemedicine practice, however, we do not offer things such as immunizations, in-house labs/ testing/imaging, screening exams, or procedures. We do not provide urgent or emergency care. 

We have on-site strep, Covid and influenza testing available.

We do not perform on-site blood draws, but we can provide the necessary lab requisitions and referral forms so that you can get your testing at your local facilities. Many of the 'specialty' or functional tests that we recommend can be drop-shipped to your home. You may then complete the test at home and mail it back to the lab directly. This provides an added convenience that many patients appreciate. 

Messaging is a great way to communicate with Dr. Coller for brief updates, simple questions, or clarification of your existing treatment plan.

More complex concerns—such as new symptoms, reviewing test results, changing a treatment plan, or questions that require a detailed response—are better addressed during an appointment. If Dr. Coller thinks that you would be better served by an appointment, he may encourage you to schedule a visit.

As a general guide, messages should be brief enough to fit within the portal's character limit. If your question or update requires multiple messages to explain, it's probably better suited for an appointment.

Since we prioritize what you need above what 3rd parties are willing to pay for, we are a cash-based practice. We do not participate with any insurance plans, including Medicare or Medicaid. 

With private or commercial insurance plans, patients may receive out-of-network reimbursement for our services if they submit their superbill/invoice to their insurer. However, since Dr. Coller is not enrolled in Medicare or Medicaid, government plans such as Medicare and Medicaid cannot be submitted for reimbursement. 

Sometimes insurance can be billed for certain labs and other tests. Specialty tests are often not covered. 

Since each plan is unique to the patient, we cannot ensure coverage or reimbursement from any insurance plan. 

Ultimately, although we will offer support where we can, it is each patient's responsibility to understand their insurance plan and negotiate with them for payment or reimbursement.

Please see the Pricing page for information about services and fees. 

We do not have any additional fees as pertain to Dr. Coller's involvement in your case. As outlined in the visit descriptions on the Pricing page, Dr. Coller will dedicate time to your case outside of visits. However, we do not charge additional fees for this. Instead, we have built this time into your PFM care fees. 

Labs, specialty tests, medications, and supplements are separate from Precision's services and will have costs of their own. These costs will vary by patient depending on what is recommended and your health insurance coverage. Dr. Coller and his team will do their best to help you navigate these things with as much transparency as possible. 

Yes.

Our Continuing Care Membership has its own monthly payment option of $135/month for 12 months and is separate from the interest-free payment plan.

Please note: we do not provide itemized superbills for prepaid packages or membership plans.

Interest-free payment arrangements may be available when needed, typically at $200/month until the applicable balance is paid.

This is simply a way to spread out the cost of care and is separate from the Continuing Care Membership.

Yes. As a physician, Dr. Coller's services should qualify you to be reimbursed with your FSA or HSA funds. Supplements and testing can sometimes qualify as well. If your program requires a letter of medical necessity, we will be happy to supply that for you.
