What Is Step Therapy in Health Insurance?
Your doctor prescribes a medication, you take it to the pharmacy, and the pharmacist tells you your insurance will not cover it until you try a different drug first. This frustrating scenario is the result of step therapy, a cost-management tool used by health insurers and pharmacy benefit managers. Also known as “fail first” protocols, step therapy requires you to try one or more lower-cost medications before your plan will approve coverage for the drug your doctor originally prescribed.
According to the American Medical Association, step therapy policies affect millions of prescriptions annually and are one of the most common sources of friction between patients, doctors, and insurance companies. Understanding how step therapy works, and how to navigate around it when necessary, puts you in a stronger position to get the treatment you need.
How Step Therapy Works
Step therapy follows a tiered approach. Your insurer establishes a sequence of medications for a given condition, starting with the least expensive option and progressing to more costly alternatives. You must try each “step” and demonstrate that it is ineffective or causes unacceptable side effects before your plan will cover the next option.
For example, if your doctor prescribes a brand-name anti-inflammatory, your insurer might require you to first try ibuprofen or naproxen, which are available as generics. If those do not adequately manage your condition, you would document the failure and move to the next step, which might be a prescription-strength NSAID. Only after that step also fails would the brand-name medication be approved for coverage.
The number of required steps varies by condition and insurer. Some protocols have two steps, while complex treatment areas like autoimmune diseases or mental health conditions may have three or more.
Why Insurers Use Step Therapy
Insurance companies implement step therapy primarily to control prescription drug costs. Generic and lower-tier medications are significantly cheaper than brand-name or specialty drugs. By requiring patients to start with less expensive options, insurers reduce spending on high-cost prescriptions when a cheaper alternative might work just as well.
From a clinical perspective, step therapy can align with evidence-based medicine. For many conditions, first-line treatments recommended by medical guidelines are also the less expensive options. Starting with these medications makes medical sense independent of cost considerations.
However, critics argue that step therapy prioritizes cost savings over individual patient needs. A drug that works well for most patients may not work for a specific patient due to genetic factors, drug interactions, or comorbidities. The “fail first” requirement can delay effective treatment and cause unnecessary suffering. For more on how insurers manage coverage decisions, see our article on prior authorization.
Step Therapy vs. Prior Authorization
Step therapy and prior authorization are related but distinct processes. Prior authorization requires your doctor to get approval from your insurer before a specific treatment is covered. Step therapy is a specific type of prior authorization that mandates trying alternative treatments first.
A medication might require prior authorization without step therapy. In that case, your doctor submits documentation supporting the prescription, and the insurer decides whether to approve it based on medical necessity. With step therapy, the insurer adds the additional requirement that you must have tried and failed on specific alternative medications before approval is granted.
Conditions Commonly Subject to Step Therapy
Step therapy protocols are most prevalent in therapeutic areas where multiple treatment options exist. These include high cholesterol, where statins have several generic options; depression and anxiety, with numerous generic antidepressants available; chronic pain management; rheumatoid arthritis and other autoimmune conditions; diabetes, particularly for newer injectable medications; and high blood pressure.
Specialty medications, which can cost thousands of dollars per month, are especially likely to have step therapy requirements. Biologic drugs for conditions like psoriasis, Crohn’s disease, and multiple sclerosis often sit at the final step, requiring patients to try several conventional treatments first.
How to Request a Step Therapy Exception
If you or your doctor believe that step therapy is inappropriate for your situation, you can request an exception. Grounds for an exception typically include having already tried and failed the required medications before enrolling in your current plan, medical contraindications that make the lower-step drugs unsafe for you, a condition that could worsen during the time needed to try alternative medications, or the required drug being clinically inappropriate due to drug interactions.
To request an exception, your doctor submits a request to your insurer with supporting clinical documentation. This should include your medical history, the medications you have previously tried, the reasons those medications were ineffective or inappropriate, and clinical evidence supporting the prescribed treatment.
Many states have enacted step therapy reform laws that require insurers to grant exceptions under certain circumstances. According to the National Conference of State Legislatures, over 30 states have adopted some form of step therapy protections.
What to Do If Your Step Therapy Exception Is Denied
If your exception request is denied, you have the right to appeal. The appeals process is similar to appealing any claim denial. Start with an internal appeal, where a different reviewer at your insurance company reconsiders the decision. If the internal appeal fails, request an external review by an independent third party.
During the appeals process, gather comprehensive documentation. A strong appeal includes your doctor’s letter explaining why the specific medication is necessary, records of prior medication trials and their outcomes, relevant clinical guidelines or medical literature, and a detailed account of how the condition affects your daily life.
Your doctor’s involvement is critical. Physicians who provide detailed, condition-specific documentation significantly increase the chances of a successful appeal. Ask your doctor to write a letter of medical necessity specifically addressing the step therapy requirement.
The Impact of Step Therapy on Treatment
Research on step therapy outcomes is mixed. Some studies show that step therapy protocols reduce healthcare spending without significantly affecting clinical outcomes. Others find that mandatory step therapy delays effective treatment, leading to disease progression, emergency room visits, and higher long-term costs.
A 2019 study published in the Journal of Managed Care and Specialty Pharmacy found that step therapy for rheumatoid arthritis was associated with higher rates of hospitalization and emergency department use compared to patients who received their doctor’s first-choice medication. This suggests that for some conditions, the short-term savings from step therapy may be offset by higher costs elsewhere in the system.
For patients, the practical impact depends on the specific condition and how quickly alternative medications are tried and evaluated. For conditions that progress rapidly, delays of weeks or months can have meaningful clinical consequences. For stable conditions with multiple well-established treatment options, step therapy may cause minimal disruption.
Frequently Asked Questions
Can my doctor override step therapy?
Your doctor can request an exception or override, but the insurer makes the final coverage decision. A well-documented exception request with clear clinical justification has a higher chance of approval. If denied, you can appeal the decision.
How long does step therapy take?
Each step typically requires trying the medication for a specified period, often 30 to 90 days, before it can be considered a failure. A three-step protocol could take three to nine months to complete before the originally prescribed medication is covered.
Does step therapy apply if I switch insurance plans?
Generally, yes. Your new insurer may not recognize medication trials completed under a previous plan unless you can provide documentation. This is one of the most common reasons for requesting a step therapy exception when changing insurance.
Is step therapy legal?
Yes, step therapy is legal, though many states have passed laws requiring insurers to provide exception processes and respond to exception requests within specific timeframes. Federal rules under the ACA also require insurers to have internal and external appeals processes for coverage denials.
Key Takeaway
Step therapy requires you to try lower-cost medications before your insurer will cover the drug your doctor prescribed. While it can reduce costs when a generic alternative works, it can also delay effective treatment. Know your rights: you can request an exception with proper medical documentation, and you can appeal a denial. Work with your doctor to build a strong case, keep records of every medication trial, and be persistent in advocating for the treatment that is right for your condition.
