On an annual basis, CareSource completes an assessment of satisfaction with the UM process and identifies any areas for improvement opportunities.

Prior Authorization

CareSource understands that you may have questions about prior authorization. Access the Prior Authorization webpage for detailed information.

Medical Necessity Criteria

CareSource utilizes nationally recognized criteria to determine medical necessity and appropriateness of inpatient hospital, rehabilitation and skilled nursing facility admissions. These criteria are designed to assist health care partners in identifying the most efficient quality care practices in use today. They are not intended to serve as a set of rules or as a replacement for a physician’s medical judgment about individual patients. CareSource defaults to all applicable state and federal guidelines regarding criteria for authorization of covered services. CareSource also has policies developed to supplement nationally recognized criteria. If a patient’s clinical information does not meet the criteria, the case is forwarded to a CareSource Medical Director for further review and determination. Physician reviewers from CareSource are available to discuss individual cases with attending physicians upon request.

Utilization review determinations are based only on appropriateness of care and service and existence of coverage. CareSource does not reward health care partners or our own staff for denying coverage or services. There are no financial incentives for our staff members that encourage them to make decisions that result in underutilization.

Our members’ health is always our number one priority. Upon request, CareSource will provide the clinical rationale or criteria used in making medical necessity determinations. You may request the information by calling or faxing the CareSource Medical Management Department. If you would like to discuss an adverse decision with physician reviewer, please call the Medical Management department at 1-833-230-2101 within five business days of the determination.
