Private practices would indeed have their expenses arranged in the fashion you describe, i.e. with those qualifying expenditures counted as business expenses before pass-through. The caveat is that titling the private practice as the malpractice policy holder, so that the insurance costs become business expenses, exposes the corporation to lability, not just the individual physician. For practices involving multiple physicians, or which own/rent property to operate a clinic, this liability exposure can be undesired. Relating from a relative who is a physician, who has been a contractor and an employee, I have to stress the general point that professional expense accounting for doctors is quite unique, due to substantial involvement of insurance and regulatory concerns. It's not easily relatable to other professions. Likewise, doctors, despite making very generous compensation, are often still frequently struggling with their employers/contractees, or with 3rd parties like insurance providers, pushing costs onto them. Since telemedicine doesn't really exist in significant form, doctors don't always have the option of quitting and finding better work in the same city/state.
