Indiana
Indiana became the 19th state to pass legislation (SB 303) on 04/21/17 now found in Indiana Code TITLE 25. Professions and Occupations ARTICLE 1. GENERAL PROVISIONS CHAPTER 10. Direct Primary Care Agreements defining direct primary care as outside of insurance (the measure can be tracked here). DPC practices are already operational within the state. It is still wise to review the Indiana Insurance Code when planning your DPC practice.
Physician and mid-level dispensing are permitted in Indiana. Please see Indiana Pharmacy Laws. IC 35-48-7-5.8 a practitioner is defined as, “…a Physician, Dentist, Veterinarians, Podiatrists, Nurse Practitioners, Scientific Investigators, Pharmacists, Hospital, or any other institution or individual licensed, registered, or otherwise permitted to distribute, dispense or conduct research with respect to, or administer a controlled substance in the course of professional practice or research in the United States.”
The Medical Licensing Board of Indiana does not appear to have a formal dispensing physician enrollment process, but contacting them to confirm this may be wise. I do not recommend contacting the Indiana Board of Pharmacy since questioners have reported inconsistent answers from their office.
IC 16-42-3-6 Drugs Dispensed on Prescription appears to be the most relevant section of the Indiana Code to physician dispensing questions and Northwind Pharmaceuticals offers a helpful discussion as well.
