Most acute care hospitals take part in the CMS Promoting Interoperability (PI) Program. You can reach out to the person(s) in charge of quality reporting for your hospital. Critical access hospitals (CAHs) are also eligible to participate in the CMS PI Program. Other types of hospitals that provide inpatient care are not included in the CMS PI Program. This includes, but is not limited to, Inpatient Rehabilitation Facilities (IRFs), Inpatient Psychiatric Facilities (IPFs), and Long Term Care Hospitals (LTCHs/LTACs/LTACHs).
