 Trustindex verifies that the original source of the review is Google. In short, I found the group … terrific. Comfortable. Caring. And knowledgeable. Far exceeding any medical group I have dealt with in years.

 Trustindex verifies that the original source of the review is Google. Philadelphia Integrative Medicine has been a lifesaver for me. When I first went, a year ago,, I felt like I was 85 and aging fast. Now I feel, if anything, younger than my actual 64, and getting better all the time. Three people this week told me they thought I was 55! PIM's comprehensive, detailed approach is based in extensive testing, so there's a whole lot less guesswork and a whole lot more success. I have seen both Dr. Tetlow and Dr. Patterson and am a huge fan of both. Cannot recommend highly enough. Pricey, but worth every penny if you can swing it.

 Trustindex verifies that the original source of the review is Google. I am a relatively new but, so far, a very satisfied PIM customer. After 10 months of looking for a health care provider who would listen to, collaborate with and communicate with me to treat ongoing GI issues, I found Amy Nutter (NP) and Jennifer Patterson (DO). Both women are smart, thorough, compassionate, and very responsive to the follow-up questions I ask between appointments. To a person, everyone with whom I have interacted in the office is exceptionally professional and kind. Thank you for being there, PIM!

 Trustindex verifies that the original source of the review is Google. I have pursued many avenues to get a resolution to my health issues - which included at times debilitating fatigue, headaches, and GI issues - and through comprehensive labwork and a holistic approach I not only have answers to the underlying causes, but am feeling better in the first time in ~4 years of trying to find an answer to my health issues thanks to the team at Philadelphia Integrative Medicine.

 Trustindex verifies that the original source of the review is Google. PIM is life changing. My wife was treated about five years ago to resolve some long standing issues no regular primary care doc nor specialists she saw could get to the bottom of. Years later I signed up and am receiving the same exceptional care and attention you would want from your Doctor. If all medical care could be done this way, our world would just be better. All members of PIM from Dr. Tetlow to her scribe give me (and gave my wife) the utmost care, compassion and competence. We recommend this practice to EVERYONE, including other practitioners as the model of what healthcare should be.

 Trustindex verifies that the original source of the review is Google. My Dr. is Dr. Patterson. My experience is that she is smart, thoughtful, thorough and engages me in my own health journey. Exactly what I want in a doctor. I enjoy consulting with her and respect and appreciate her advice and opinion.

What are the appointment costs?

We offer individual appointments or an appointment package. Please see our pricing page for more information including pricing and appointment lengths.

What are the costs of testing and supplements?

Your PIM provider may recommend personalized testing and supplements during your initial and follow-up visits. Costs vary based on your health goals. Testing fees are separate from appointment fees. On average, patients spend around $150/month on supplements, though this may be higher initially and decrease as you progress.

I received an EOB from my insurance company, what should I do?

We are aware that some patients receive an Explanation of Benefits (EOB) from their insurance company and this resembles a bill or notes that you (the patient) may be responsible for a certain amount and this can be alarming. Rest assured that an EOB is NOT a bill. We are able to provide upfront amounts for all specialty testing in order to avoid surprise bills.

LabCorp and Quest testing costs vary depending on your coverage and we always suggest calling your insurance company to inquire about costs before completing your test.

Please wait until you receive a bill. If you do receive an unexpected bill from a testing company, please always email a copy of the bill to info@philly-im.com and we are happy to do everything we can to possible reduce or eliminate the bill for you.
