What Is Step Therapy?

Step therapy is a requirement that patients try lower-cost treatments before an insurer will approve a more expensive or preferred option. For example, a plan may require trying two generic medications before approving a brand-name drug.

Step therapy requirements are the most common unmet criteria in prior authorization denials. If you have already completed these steps — even years ago with a different provider — that history must be documented and submitted.

What Are Step Therapy Override Laws?

Step therapy override laws require insurers to allow patients to bypass step therapy requirements under specific circumstances. More than 29 states have enacted these protections. However, these laws apply only to state-regulated (fully insured) commercial plans — they do not apply to self-insured ERISA plans, which are governed by federal law.

Common Override Criteria

Most state override laws require exceptions under one or more of the following circumstances:

The required step therapy drug is contraindicated for the patient
The patient previously tried and failed the required drug
The patient previously tried the required drug at a different dose and it was inadequate
The required drug would cause an adverse reaction based on the patient's other medications
The patient is stable on the requested drug and a change would cause harm
The required drug is not clinically appropriate for the patient's condition
How to Invoke a Step Therapy Override
STEP 01
Confirm Your Plan Type
Is your insurance fully insured (state-regulated) or self-insured (ERISA)? Check your Summary of Benefits and Coverage or ask your employer's HR department. This determines whether state override laws apply.
STEP 02
Check If Your State Has an Override Law
States with step therapy override laws include but are not limited to: Arkansas, Colorado, Connecticut, Delaware, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maine, Maryland, Michigan, Minnesota, Mississippi, Montana, Nebraska, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Oklahoma, Oregon, Pennsylvania, Tennessee, Texas, Utah, Virginia, Washington, and West Virginia. Verify current status with your state Department of Insurance as laws change.
STEP 03
Request the Exception in Writing
Your provider must submit a written exception request citing the applicable state law, the clinical reason the required step therapy is inappropriate, and documentation supporting the exception criteria.
STEP 04
Escalate If Denied
If the exception is denied, file a complaint with your state Department of Insurance citing the specific override law. Most states require insurers to respond to exception requests within defined timeframes.
The exception request must be submitted by your provider, not by you directly. Give your provider a copy of this guide and ask them to cite your state's specific step therapy override statute.
