Rush Prudential HMO, Inc. v. Moran

2002-06-20

Headline: Illinois law requiring independent physician review of some HMO benefit denials is upheld, allowing state review rules to apply to ERISA-covered health plans and affecting patients and insurers nationwide.

Holding: The Court held that Illinois’s independent medical-review law for certain HMO benefit denials is not preempted by ERISA, so the state review requirement can be applied to ERISA-covered health plans.

Real World Impact:

Allows states to require independent external medical review of HMO benefit denials.
Some denied treatments may become covered after a state reviewer finds them medically necessary.
Could raise costs for HMOs and affect employer plan design.

Summary

Background

Debra Moran, a woman covered by her husband's employer health plan, sought reimbursement after an HMO (Rush Prudential) refused to pay for an unconventional surgery. Rush’s certificate promised coverage for “medically necessary” care but gave Rush broad discretion to decide that term. When Moran’s primary doctor and Rush disagreed, she demanded the independent review the Illinois HMO law (§4-10) guarantees. An unaffiliated reviewer found the surgery medically necessary, Rush still denied payment, and the parties litigated whether the state review law is preempted by federal ERISA rules.

Reasoning

The Court framed the question as whether ERISA, which can override state laws, blocks Illinois’s review rule. The majority concluded §4-10 is a law that “regulates insurance” and so is saved from ERISA preemption because HMOs perform insurance functions and the statute targets insurance practices. The Court distinguished prior cases that struck down state remedies by noting §4-10 does not create a new cause of action or a new form of final relief. Instead, it operates like an independent medical opinion focused on the contract term “medical necessity,” carried out by a physician with similar credentials to the patient’s doctor, and therefore does not conflict with ERISA’s federal enforcement scheme.

Real world impact

As a result, state independent external review rules can apply to HMOs that serve ERISA plans. Some denied treatments may be reversed after a state reviewer finds them necessary, and HMOs and employers may need to adjust procedures. The decision leaves ERISA’s federal remedies intact while allowing state insurance regulation to affect how benefit disputes are resolved.

Dissents or concurrances

Justice Thomas dissented, warning that allowing different state review schemes undermines ERISA’s goal of uniform national rules and could produce inconsistent remedies and higher costs.
