CMS, on November 16, 2010, issued new rules for Medicare- and Medicaid-participating hospitals that protect patients' rights to choose their own visitors during a hospital stay, including a visitor who is a same-sex domestic partner. The new rules follow from an April 15, 2010, Presidential Memorandum on the subject and update the Conditions of Participation, which are the health and safety standards all Medicare- and Medicaid-participating hospitals and critical access hospitals must meet and are applicable to all patients of those hospitals regardless of payer source. The rules require hospitals to have written policies and procedures detailing patients' visitation rights, as well as the circumstances under which the hospitals may restrict patient access to visitors based on reasonable clinical needs. Among other things, the rules impose new requirements on hospitals to explain to all patients their right to choose who may visit them during their inpatient stay, regardless of whether the visitor is a family member, a spouse, a domestic partner (including a same-sex domestic partner) or other type of visitor, as well as their right to withdraw such consent to visitation at any time.
