What Is Mitigation of Damages in Personal Injury Cases?

James Wong — Founder & CEO, LienScripts | March 4, 2026 | 6 min read

Mitigation of damages is the legal duty of an injured plaintiff to take reasonable steps to minimize the harm caused by the defendant's negligence. Failure to mitigate — including failure to take prescribed medications — can reduce the plaintiff's recovery.

Mitigation of damages is a legal doctrine requiring an injured plaintiff to take reasonable steps to minimize the losses and harm caused by the defendant's wrongful conduct. In personal injury cases, the duty to mitigate means the plaintiff must seek appropriate medical treatment, follow prescribed treatment plans, and avoid conduct that would worsen the injury — and if the plaintiff fails to do so, the defendant may argue that damages should be reduced by the amount that could have been avoided through reasonable mitigation efforts.

• The duty to mitigate does not require the plaintiff to undergo unreasonable, risky, or excessively expensive treatment — only reasonable steps
• Failure to fill prescribed medications is one of the most common mitigation-of-damages arguments raised by defense counsel
• A pharmacy lien through LienScripts eliminates the most common barrier to medication compliance — cost — ensuring the plaintiff can demonstrate full mitigation
• LienScripts generates a MERIT (Medication Evaluation & Rationale for Injury Treatment) report for every case, providing pharmacist-signed documentation for demand packages
• According to James Wong, PharmD, founder of LienScripts, "The mitigation defense is one of the strongest arguments defense counsel has — and it is entirely preventable when patients have access to a pharmacy lien that removes the financial barrier to filling prescriptions"

The Legal Standard

The mitigation doctrine operates as a limitation on recoverable damages, not as an affirmative defense that bars the claim entirely. The defendant must prove:

1. The plaintiff failed to take reasonable steps to reduce harm after the injury
2. The failure increased the plaintiff's damages beyond what they would have been with reasonable mitigation
3. The steps the plaintiff should have taken were reasonable under the circumstances

The burden of proof is on the defendant to establish all three elements. The plaintiff is not required to prove that mitigation efforts were undertaken — but practically, demonstrating active treatment compliance strengthens the case significantly.

Mitigation and Medication Compliance

The most common mitigation argument in personal injury cases involving pharmacy liens is failure to fill or take prescribed medications. Defense counsel points to gaps in the prescription record and argues:

• The plaintiff was prescribed pain medication but did not fill it — therefore the pain was not as severe as claimed
• The plaintiff was prescribed anti-inflammatory medication but stopped filling it — therefore the inflammation resolved on its own
• The plaintiff was prescribed neuropathic medication but never started it — therefore the nerve pain was not disabling

Each of these arguments directly attacks both the credibility of the plaintiff and the extent of recoverable damages.

How a Pharmacy Lien Eliminates the Mitigation Problem

When a plaintiff cannot afford to fill prescriptions, the mitigation defense becomes particularly powerful — and particularly unfair. The plaintiff is caught between financial reality (inability to pay for medications) and legal exposure (being penalized for not filling them).

A pharmacy lien through LienScripts eliminates this problem entirely. The lien arrangement provides all prescribed medications at zero upfront cost. The plaintiff has no financial barrier to compliance. Every prescription is filled, every fill is documented, and the complete medication record demonstrates full mitigation of damages.

This means:

• No gaps from cost barriers — the most common reason for unfilled prescriptions is eliminated
• Complete documentation — every filled prescription is timestamped and recorded
• Prescriber intent preserved — every medication the doctor ordered was dispensed and available to the patient
• Defense argument neutralized — there is no basis for arguing failure to mitigate through medication non-compliance

What "Reasonable" Mitigation Requires

The mitigation duty has limits. A plaintiff is not required to:

• Undergo surgery if reasonable minds could disagree about its necessity or risks
• Accept experimental treatment that is not widely accepted in the medical community
• Incur unreasonable expense to pursue treatment — although this argument weakens when a lien removes the cost barrier
• Follow every recommendation perfectly — isolated instances of non-compliance do not establish failure to mitigate unless they demonstrably worsened outcomes

Courts apply an objective reasonableness standard: would a reasonable person in the plaintiff's position have taken the mitigation steps the defendant says should have been taken?

Strategic Implications for Attorneys

Personal injury attorneys should address mitigation proactively:

• Establish the pharmacy lien early — the sooner medications are covered by the lien, the fewer gaps appear in the record
• Document the reason for any gaps — if a patient had a period without medications before the lien was established, document why (cost, insurance denial, provider delay)
• Use the MERIT report — LienScripts' Medication Evaluation & Rationale for Injury Treatment (MERIT) report provides a pharmacist-signed timeline of all medication fills, which directly demonstrates mitigation compliance

As Amar Lunagaria, PharmD, LienScripts' Chief Pharmacist explains, "The MERIT report is essentially a mitigation compliance document — it shows that the patient filled every prescription, followed the treatment plan, and took reasonable steps to recover."
