(1) The department adopts and incorporates by reference the Medicaid Adult Mental Health and the Adult Mental Health Services Plan fee schedule as provided in ARM 37.85.105(5). A copy of the department's fee schedule is posted at the Montana Medicaid provider web site at www.dphhs.mt.gov/amdd/services/index/shtml. A copy may be obtained from the Department of Public Health and Human Services, Addictive and Mental Disorders Division, PO Box 202905, Helena, MT 59620-2905. Medicaid reimbursement for mental health center services will be the lowest of:

(a) the provider's actual (submitted) charge for the service; or

(b) the department's fee for the service as specified in the department's fee schedules.

(2) The provider reimbursement rate for a covered service for mental health centers is stated in the department's fee schedule adopted and effective at ARM 37.85.105(5). These fees are calculated based on:

(a) the biennial legislative appropriation; and

(b) the estimated demand for covered services during the biennium.

(3) For day treatment, program of assertive community treatment, and crisis intervention services, Medicaid will not reimburse a mental health center provider for more than one fee per treatment day per individual. This does not apply to practitioner services to the extent such services are separately billed in accordance with these rules.

(4) For purposes of Medicaid billing and reimbursement of day treatment services, a "half day" means that the individual has attended the day treatment program for a minimum of two hours during the treatment day.

(5) For purposes of meeting the minimum hours required in (3), the provider may not include time during which the individual is receiving practitioner services that are billed separately as practitioner services under ARM 37.88.906, up to a maximum of four hours during the treatment day.

(6) Services billed as community-based psychiatric rehabilitation and support may not be counted toward the time requirements for any other service or billed by the provider as any other type or category of service.

(7) Reimbursement will be made to a provider for reserving an adult foster care or mental health adult group home bed only if:

(a) the individual's plan of care documents the medical need for a therapeutic visit as part of a therapeutic plan;

(b) the individual is temporarily absent on a therapeutic visit;

(c) the provider clearly documents staff contact and individual achievements or regressions during and following the therapeutic visit; and

(d) no more than 14 patient days per individual in each rate year will be reimbursed for therapeutic visits.
