What Is Step Therapy (Fail-First) and How Do I Fight It?

Step therapy — also called "fail-first" — is a cost-management strategy used by health insurers that requires patients to try and fail at least one (often cheaper) treatment before the insurer will approve coverage for the treatment their physician originally prescribed. It is one of the most controversial practices in managed care and a frequent source of insurance denials.

How Step Therapy Works

Imagine your doctor prescribes a biologic medication for your rheumatoid arthritis. Instead of covering it right away, your insurer may require you to first try:

1. A generic DMARD (disease-modifying antirheumatic drug) for 3–6 months
2. If that fails, a second-line agent for another period
3. Only then — if both fail — will the insurer approve the biologic your doctor originally recommended

The insurer frames this as "evidence-based" protocol. Critics — including most patient advocacy groups — argue it puts administrative barriers above physician judgment, causes delays in effective treatment, allows conditions to worsen, and increases total costs when untreated conditions deteriorate.

Common Conditions Targeted by Step Therapy

Step therapy requirements are most common in:

• Rheumatoid arthritis and inflammatory conditions (biologics and JAK inhibitors)
• Mental health medications (antidepressants, antipsychotics)
• Asthma and COPD (inhaled corticosteroids, bronchodilators)
• Gastrointestinal conditions (IBS, IBD)
• Diabetes medications
• Migraine treatments

Why Step Therapy Denials Are Appealable

Step therapy requirements are not absolute. Most insurers — and many states — allow for step therapy exceptions when:

• The patient has already tried and failed the required prior-step treatment (with documentation)
• The required prior-step treatment is contraindicated for the patient (allergy, drug interaction, comorbidity)
• The required prior-step treatment is expected to be clinically ineffective based on the patient's diagnosis or genetic factors
• Starting the prior-step treatment would cause irreversible harm or delay clinically urgent care

How to Request a Step Therapy Exception

Document prior failures: If you have previously tried the required medication — even with a different insurer or years ago — gather records proving the trial and the failure (adverse effect, lack of efficacy, discontinuation reason).

Get a contraindication letter: Your physician should write a letter explaining why the required step-therapy drug is inappropriate for you specifically, citing clinical reasons.

Cite published guidelines: If major specialty guidelines (ACR, AHA, NCCN, etc.) recommend starting with the prescribed drug for your condition, include that documentation.

Submit a formal exception request: Most insurers have a specific step therapy exception form. Submit it through your insurer's Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization channel with all supporting documents.

State Step Therapy Laws

More than 30 states have enacted step therapy reform laws that standardize exception criteria and timelines. If you are in one of these states, the insurer must grant an exception within a defined timeframe (often 72 hours for urgent cases) if the clinical criteria are met. If the insurer fails to respond in time, many state laws deem the exception automatically approved.

The NCSL (National Conference of State Legislatures) maintains a tracker of state step therapy laws.
