42 CFR §483.112

1. (a)Determination of need for NF services. For each NF applicant with MI or IID, the State mental health or intellectual disability authority (as appropriate) must determine, in accordance with § 483.130, whether, because of the resident's physical and mental condition, the individual requires the level of services provided by a NF.
2. (b)Determination of need for specialized services. If the individual with mental illness or intellectual disability is determined to require a NF level of care, the State mental health or intellectual disability authority (as appropriate) must also determine, in accordance with § 483.130, whether the individual requires specialized services for the mental illness or intellectual disability, as defined in § 483.120.
3. (c)Timeliness—(1) Except as specified in paragraph (c)(4) of this section, a preadmission screening determination must be made in writing within an annual average of 7 to 9 working days of referral of the individual with MI or IID by whatever agent performs the Level I identification, under § 483.128(a) of this part, to the State mental health or intellectual disability authority for screening. (See § 483.128(a) for discussion of Level I evaluation.)
   1. (2)The State may convey determinations verbally to nursing facilities and the individual and confirm them in writing.
   2. (3)The State may compute separate annual averages for the mentally ill and individuals with intellectual disabilities/developmentally disabled populations.
   3. (4)The Secretary may grant an exception to the timeliness standard in paragraph (c)(1) of this section when the State—
      1. (i)Exceeds the annual average; and
      2. (ii)Provides justification satisfactory to the Secretary that a longer time period was necessary.
