Medical Policies and Clinical UM Guidelines

There are several factors that impact whether a service or procedure is covered under a member’s beneļ¬t plan. Medical policies and clinical utilization management (UM) guidelines are two resources that help us determine if a procedure is medically necessary. These guidelines are available to you as a reference when interpreting claim decisions.

Medical Policies

Medical Policies are used by all plans and lines of business unless Federal or State law—as well as contract language, including definitions and specific contract provisions or exclusions—take precedence over a medical policy. Those provisions will be considered first in determining eligibility for coverage before the medical policy is used to determine medical necessity.

Clinical UM Guidelines

The Clinical UM guidelines published on this website are not always used by all plans or lines of business. Clinical UM guidelines are available for adoption to review the medical necessity of services related to the guideline when the Plan performs a utilization review for the subject. Because practice patterns, claims systems and benefit designs vary, a local plan may choose whether to adopt a particular clinical UM guideline.
Health plans or lines of business which determine there is not a need to adopt a clinical utilization management guideline may instead use the guideline for educational purposes or to review the medical necessity of services for any provider who has been notified that his or her claims will be reviewed due to billing practices or claims that are inconsistent with other providers.
To determine which clinical utilization management guidelines have been adopted by your plan, or to determine if there are applicable other criteria, you can use the guideline adoption link provided below.

In addition to the documents we develop and maintain for coverage decisions, we may adopt criteria developed and maintained by other organizations. Note that where we have developed a medical policy that addresses a service also described in one of these other sets of criteria, the plan’s medical policy supersedes.
