39-71-1101. Choice of physician by worker -- change of physician -- receipt of care from managed care organization. (1) Subject to subsection (3), a worker may choose the initial treating physician within the state of Montana.
     (2) Authorization by the insurer is required to change treating physicians. If authorization is not granted, the insurer shall direct the worker to a managed care organization, if any, or to a medical service provider who qualifies as a treating physician, who shall then serve as the worker's treating physician.
     (3) A medical service provider who otherwise qualifies as a treating physician but who is not a member of a managed care organization may not provide treatment unless authorized by the insurer, if:
     (a) the injury results in a total loss of wages for any duration;
     (b) the injury will result in permanent impairment;
     (c) the injury results in the need for a referral to another medical provider for specialized evaluation or treatment; or
     (d) specialized diagnostic tests, including but not limited to magnetic resonance imaging, computerized axial tomography, or electromyography, are required.
     (4) A worker whose injury is subject to the provisions of subsection (3) shall, unless otherwise authorized by the insurer, receive medical services from the managed care organization designated by the insurer, in accordance with 39-71-1104. The designated treating physician in the managed care organization then becomes the worker's treating physician. The insurer is not liable for medical services obtained otherwise, except that a worker may receive immediate emergency medical treatment for a compensable injury from a medical service provider who is not a member of a managed care organization.
