Mont. Code Ann. § 46-1-1110

46-1-1110 . Treatment and support services. (1) As part of a diagnostic assessment, each jurisdiction shall establish a system to ensure that drug offenders are placed into a clinically approved substance abuse treatment program. To accomplish this, the program conducting the individual assessment shall make specific recommendations to the drug treatment court team regarding the type of treatment program and durations necessary so that a drug offender's individualized needs are addressed. The assessments and recommendations must be based upon objective medical diagnostic criteria. Treatment recommendations accepted by the court pursuant to this part must be considered to be reasonable and necessary.

(2) An adequate continuum of care for drug offenders must be established in response to this part.

(3) The drug treatment court shall, when practicable, ensure that one agency may not provide both assessment and treatment services for the drug treatment court to avoid potential conflicts of interest or the appearance that a diagnostic assessment agency might benefit by determining that an offender is in need of the particular form of treatment that the agency provides.

(4) A drug treatment court making a referral for substance abuse treatment shall refer the drug offender to a program that is licensed, certified, or approved by the court.

(5) The court shall determine which treatment programs are authorized to provide the recommended treatment to drug offenders. The relationship between the treatment program and the court must be governed by a memorandum of understanding, which must include the timely reporting of the drug offender's progress or lack of progress to the drug treatment court.

(6) Offenders must be provided with adequate support services and aftercare.

(7) The length of stay in treatment must be determined by the drug treatment court team based on individual needs and accepted practices.
