Montana Independent Medical Review Form is a document used by the Montana Department of Public Health and Human Services (DP HHS) to evaluate medical claims submitted by health care providers. It is used to determine the appropriateness of proposed medical treatments and to ensure that quality medical care is provided. There are two types of Montana Independent Medical Review Form: the Pre-Approval Request form and the Post-Approval Request form. The Pre-Approval Request form is used by health care providers to seek approval for medical treatments before they are performed. The Post-Approval Request form is used by health care providers to request reimbursement for medical treatments after they have been provided. Both forms require detailed information about the proposed treatments and the patient's medical history.
