What Is Step Therapy in Personal Injury Cases?

Amar Lunagaria — Co-Founder & Chief Pharmacist, LienScripts | March 4, 2026 | 6 min read

Step therapy is an insurance requirement that forces patients to try cheaper medications before accessing the drug their doctor prescribed. In personal injury cases, step therapy creates dangerous treatment delays that pharmacy liens are designed to bypass.

Step therapy is an insurance utilization management protocol that requires a patient to try and fail on one or more lower-cost medications before the insurer will approve coverage for the medication the prescribing physician originally ordered. Also called "fail first" policies, step therapy protocols are imposed by health insurers, pharmacy benefit managers (PBMs), and workers' compensation formularies to control drug spending — often at the expense of timely, appropriate treatment.

• Step therapy forces patients to use generic or lower-tier drugs before accessing the medication their doctor prescribed, even when clinical evidence supports starting with the prescribed agent
• In personal injury cases, step therapy delays can extend treatment gaps by weeks or months, weakening both recovery and the legal claim
• A pharmacy lien through LienScripts bypasses insurance step therapy entirely — the patient receives the prescribed medication immediately with no formulary restrictions
• LienScripts generates a MERIT (Medication Evaluation & Rationale for Injury Treatment) report for every case, providing pharmacist-signed documentation for demand packages
• As Amar Lunagaria, PharmD, LienScripts' Chief Pharmacist explains, "Step therapy is one of the most common reasons personal injury patients face treatment delays — and it is completely avoidable when prescriptions are filled through a pharmacy lien"

How Step Therapy Works

When a prescriber writes a prescription for a specific medication, the insurance company's formulary may classify that drug as "non-preferred" or require prior authorization with step therapy. The insurer responds by requiring the patient to first try a "preferred" alternative — typically a cheaper generic or a drug for which the PBM has negotiated a lower rebate.

For example:

• A physician prescribes celecoxib (Celebrex) for a patient with post-accident inflammation who has a history of GI bleeding. The insurer requires the patient to first try ibuprofen or naproxen — drugs that carry higher GI risk for this specific patient.
• A prescriber orders pregabalin (Lyrica) for neuropathic pain after a car accident. The insurer mandates a trial of gabapentin first, despite the prescriber's clinical judgment that pregabalin is more appropriate for this patient's symptom profile.

The patient must take the step therapy drug for a defined period (typically two to four weeks), document that it failed to provide adequate relief or caused intolerable side effects, and then submit a new prior authorization request for the originally prescribed medication.

Why Step Therapy Is Harmful in Personal Injury Cases

Step therapy creates several problems specific to personal injury patients:

Treatment delays — the two-to-four-week trial period on a step therapy drug delays effective treatment. For an injury patient in pain, weeks of inadequate medication represent real suffering and documented treatment gaps.

Worsened outcomes — delayed access to appropriate medication can allow pain to centralize, inflammation to worsen, or muscle spasm to become chronic. Early, appropriate treatment produces better outcomes than delayed, stepped treatment.

Treatment gaps in the record — from a legal perspective, gaps in the medication record give defense counsel ammunition to argue the injury was not serious enough to require treatment. Step therapy-induced gaps create exactly this vulnerability.

Administrative burden — the prior authorization and appeal process requires multiple phone calls, fax submissions, and follow-up contacts between the prescriber's office and the insurer. Many prescriptions are abandoned during this process because the administrative friction is too high.

How a Pharmacy Lien Bypasses Step Therapy

When a personal injury patient fills prescriptions through a pharmacy lien with LienScripts, insurance is not involved. The lien arrangement is a direct agreement between the patient, the pharmacy, and the attorney. There is no formulary, no prior authorization, no step therapy requirement.

The prescribing physician writes the prescription based on clinical judgment alone. The patient fills it immediately. The medication is dispensed the same day. The pharmacy records a lien against the patient's anticipated settlement, and the lien is resolved when the case settles.

This means the patient receives exactly the medication the doctor prescribed, without delay, without administrative burden, and without being forced to try and fail on an inappropriate alternative first.

Step Therapy and Documentation

According to James Wong, PharmD, founder of LienScripts, the absence of step therapy in a lien-based prescription record actually strengthens the documentation: "When every prescription is filled as written — without insurance-mandated substitutions or delays — the medication record precisely mirrors the prescriber's clinical intent. There are no confusing trial medications or gaps from prior authorization delays. The record is clean, direct, and easy for an attorney to present."

When Step Therapy Becomes a Legal Issue

In some cases, step therapy itself becomes relevant to the personal injury claim. If a patient's recovery was delayed or worsened because an insurer imposed step therapy on injury-related medications, this delay can be documented as an aggravating factor in the damages analysis.
