Payors may be insurance companies or other groups such as self-insured employers, trusts or governments. Usually, benefits for medical services or supplies that are payable under the terms of a benefit plan are paid directly by the payor. For some payors, HealthLink may make benefit recommendations and payments on behalf of the payor using payor funds.<br><br>Utilization management services provided by HealthLink are available to a payor. Not all payors purchase such services for the benefit plans they sponsor. For payors who have purchased such services, utilization management is the process by which HealthLink reviews medical services or supplies, provided or to be provided to a benefit plan member, for the purpose of making a recommendation to the payor regarding the medical necessity of such services or supplies. HealthLink's medical necessity recommendations are used by the payor to make benefit determinations. <br><br>The administrator of the benefit plan retains authority with respect to eligibility, coverage and the benefits under the benefit plan. Members should contact their local customer services representative for specific coverage information, and to determine whether their benefit plan has purchased HealthLink’s utilization management services.  Coverage recommendations are subject to all terms and conditions of the applicable benefit plan, including specific exclusions and limitations, and to applicable state and/or federal law. Medical policy does not constitute plan authorization, nor is it an explanation of benefits. <br><br>HealthLink has developed medical policies that serve as one of the sets of guidelines for coverage recommendations when it performs utilization management on behalf of a payor.  Benefit plans vary in coverage and some plans may not provide coverage for certain services discussed in the medical policies. <br><br>Medical policies can be highly technical and complex and are provided here for informational purposes. The medical policies do not constitute medical advice or medical care. Treating health care providers are solely responsible for diagnosis, treatment and medical advice.

This may include but is not limited to decisions involving pre-certification, inpatient review, level of care, discharge planning and retrospective review. The Milliman Care Guidelines&reg; licensed include (1) Inpatient and Surgical Care Guidelines, and (2) General Recovery Guidelines.  HealthLink also has the right to customize Milliman Care Guidelines® based on determinations by its Medical Policy & Technology Assessment Committee (MPTAC). <br><br>Benefit plans vary in coverage and some plans may not provide coverage for certain services discussed in the clinical UM guidelines.
