Yes. The Privacy Rule permits a covered entity, or a business associate acting on behalf of a covered entity (e.g., a collection agency), to disclose protected health information as necessary to obtain payment for health care, and does not limit to whom such a disclosure may be made.
Therefore, a covered entity, or its business associate, may contact persons other than the individual as necessary to obtain payment for health care services. See 45 CFR 164.506(c) and the definition of “payment” at 45 CFR 164.501. However, the Privacy Rule requires a covered entity, or its business associate, to reasonably limit the amount of information disclosed for such purposes to the minimum necessary, as well as to abide by any reasonable requests for confidential communications and any agreed-to restrictions on the use or disclosure of protected health information. See 45 CFR 164.502(b), 164.514(d), and 164.522.
