according to the privacy rule, what must a business associate and covered entity have in order to do a business?

In order to do business, both a business associate and a covered entity must have a valid business associate agreement or contract. The business associate agreement/contract must detail the services they will provide and their respective responsibilities to protect individuals' protected health information (PHI). The agreement/contract should also specify the extent to which the business associate or covered entity may use or disclose PHI, and the business associate must agree to abide by the HIPAA Privacy Rule. Additionally, the agreement/contract should include provisions that address indemnification for violations of the Privacy Rule, termination of the agreement/contract, and other relevant provisions.
