Covered entities are required to apply the minimum necessary standard to their own requests for protected health information. One covered entity may reasonably rely on another covered entity’s request as the minimum necessary, and then does not need to engage in a separate minimum necessary determination. See 45 CFR 164.514(d)(3)(iii).

However, if a covered entity does not agree that the amount of information requested by another covered entity is reasonably necessary for the purpose, it is up to both covered entities to negotiate a resolution of the dispute as to the amount of information needed. Nothing in the Privacy Rule prevents a covered entity from discussing its concerns with another covered entity making a request, and negotiating an information exchange that meets the needs of both parties. Such discussions occur today and may continue after the compliance date of the Privacy Rule.
