External medical review

Humana Healthy Horizons uses the following criteria to determine medical necessity:

Louisiana state regulations

Milliman Care Guidelines (MCG)

American Society of Addiction Medicine (ASAM) criteria, which are nationally recognized, evidence-based clinical utilization management (UM) guidelines

Humana coverage policies

These guidelines are intended to allow Humana Healthy Horizons to provide all members with care that is consistent with national quality standards and evidence-based guidelines. These guidelines are not intended as a replacement for a physician’s medical expertise; they are to provide guidance to our physician providers related to medically appropriate care and treatment.
