103 CMR, § 430.29
Before placement in the DDU, an inmate shall be screened by a Qualified Mental Health Professional to determine if the inmate has a serious mental illness (SMI) or to determine if placement in the DDU is otherwise clinically contraindicated based on clinical standards adopted by the Department of Correction, with said standards adopted in consultation with the Department of Mental Health, and the Qualified Mental Health Professional's clinical judgment. Additional mental health procedures and treatment attendant to DDU placement shall comport with the requirements set forth in 103 DOC 650: Mental Health Services.
Additionally, prior to or immediately upon placement in the DDU, the inmate shall be screened by medical staff to determine whether there are any medical contraindications to placement in the DDU, including the existence of a permanent physical disability that precludes placement in the DDU. In such case, the inmate shall not be placed in the DDU. This screening shall be documented and placed in the inmate's medical record.
