(2) The following definitions and abbreviations and those found in WAC 182-550-1050 apply to this section (where there is any discrepancy, this section prevails):

The certification process occurs concurrently with the prior authorization process.

(c) "IMD" See "institution for mental diseases."

(d) "Institution for mental diseases (IMD)" means a hospital, nursing facility, or other institution of more than sixteen beds that is primarily engaged in providing diagnosis, treatment, or care of people with mental diseases, including medical attention, nursing care, and related services. The MHD designates whether a facility meets the definition for an IMD.

(k) "Regional support network (RSN)" see WAC 388-865-0200.

(l) "Retrospective authorization" means a process by which hospital providers and hospital unit providers must obtain an MHD designee's certification after services have been initiated for a Washington apple health client. Retrospective authorization can be before discharge or after discharge. This process is allowed only when circumstances beyond the control of the hospital or hospital unit provider prevented a prior authorization request, or when the client has been determined to be eligible for Washington apple health after discharge.

(m) "RSN" see "regional support network."

(n) "Voluntary admission" refer to chapters 71.05 and 71.34 RCW.

(3) The following department of health (DOH)-licensed hospitals and hospital units are eligible to be paid for providing inpatient psychiatric services to eligible Washington apple health clients, subject to the limitations listed:

(a) Medicare-certified distinct part psychiatric units;

(4) An MHD designee has the authority to approve or deny a request for initial certification for a client's voluntary inpatient psychiatric admission and will respond to the hospital's or hospital unit's request for initial certification within two hours of the request. An MHD designee's certification and authorization, or a denial, will be provided within twelve hours of the request. Authorization must be requested before admission. If the hospital chooses to admit the client without prior authorization due to staff shortages, the request for an initial certification must be submitted the same calendar day (which begins at midnight) as the admission. In this case, the hospital assumes the risk for denial as the MHD designee may or may not authorize the care for that day.

The MHD designee provides a response within thirty days of the receipt of the required clinical documentation. All retrospective certifications must meet the requirements in this section.
