I don't have such a contract, but I would recommend you hire an attorney to craft a contract for you. You're going to be dealing with HIPAA and patient protected information, federal dollars, provider income and your own interests (salary, non-compete, contract parameters, etc.), not to mention you're contracting with a physician who isn't employing or protecting you, so don't take a chance with a canned document that may not cover all the bases for your interests. A single lawsuit based on an honest mistake, a software glitch or even an unintended breach could impact your personal and financial life. This is not easy work, and the list of things that can go wrong with an informal agreement or a poorly written contract could be disasterous. Also, you'll also need a BAA. A few hundred dollars for a contract is a better business decision than a six figure lawsuit.
