Cash Clinic

“I am in practice and would like to figure out a different way to contain and manage my routine foot care. It is approximately 15% of my practice. I would like to designate one morning a week as a routine foot care clinic. I am considering making this a cash only clinic: $50 for toenails and $50 for calluses. Is this possible? I am a Medicare provider and have contracts with most insurance companies. I was hoping to model my cash clinic on what some nurses in the area have done. They visit a nursing home and offer residents $25 for routine foot care and do not work with any insurance companies or Medicare. Any thoughts on this cash model, routine foot care clinic would be appreciated.”
