Preparing for Depositions Involving Pharmacy Records in PI Cases

Defense attorneys follow a predictable playbook when questioning pharmacy records in depositions. Knowing their strategy — and preparing your witness and exhibits in advance — prevents damaging concessions and strengthens the medication damages narrative.

Preparing for Depositions Involving Pharmacy Records in PI Cases

Defense attorneys follow a predictable playbook when deposing plaintiffs and treating providers about pharmacy records in personal injury cases. The questions target causation, necessity, pricing, and compliance — and an unprepared witness can make concessions that undermine the entire pharmacy lien balance. Proper preparation neutralizes these attacks before they begin.

• Depositions involving pharmacy records focus on four areas: causation, medical necessity, pricing reasonableness, and medication compliance
• Defense counsel will attempt to establish pre-existing medication use, gaps in adherence, and alternative cheaper therapies
• LienScripts provides MERIT (Medication Evaluation & Rationale for Injury Treatment) documentation that directly addresses the most common deposition attack lines
• Preparing your client and treating providers with specific pharmacy record exhibits prevents damaging admissions

[!KEY] The single most damaging deposition moment for pharmacy liens occurs when a plaintiff admits they "don't know" why a specific medication was prescribed or how it relates to the accident — preparation must ensure every plaintiff can articulate the connection between each medication and their injuries.

The Four Deposition Attack Vectors

Defense attorneys target pharmacy records through four predictable lines of questioning. Understanding each one allows you to prepare witnesses who can respond confidently rather than defensively.

1. Causation: "Were You Taking This Before the Accident?"

The defense will obtain pharmacy fill history going back years. They are looking for any medication that appears both before and after the accident date. If your client took gabapentin for any reason before the collision, defense counsel will argue the post-accident gabapentin prescription is simply a continuation of pre-existing treatment.

Preparation strategy: Review the complete pharmacy fill history with your client before the deposition. For any medication that appears in both pre- and post-accident records, prepare the client to explain the difference — different dosage, different indication, or new prescriber. According to James Wong, PharmD, founder of LienScripts, "A medication name appearing before and after an accident date tells you nothing about causation — the dose, frequency, prescribing diagnosis, and clinical context are what matter."

2. Medical Necessity: "Did Your Doctor Explain Why This Drug?"

Defense counsel will ask plaintiffs whether their doctor explained each medication, whether they understood the purpose, and whether they questioned the necessity. The goal is to establish that the plaintiff passively accepted prescriptions without understanding their clinical basis — implying the medications may have been unnecessary or provider-driven rather than clinically indicated.

Preparation strategy: Walk your client through each medication on the lien. Ensure they can state, in plain language, what the medication does and which injury symptom it addresses. They do not need to know pharmacology — they need to say "this is for the nerve pain in my left leg from the herniated disc" rather than "I don't really know, my doctor just prescribed it."

3. Pricing: "Do You Know How Much These Medications Cost?"

This line of questioning establishes that the plaintiff has no knowledge of medication pricing, creating an opening for the defense to argue that the lien amounts are unreasonable and the plaintiff had no role in controlling costs. The subtext is that someone else — the pharmacy or the attorney — is driving the billing.

Preparation strategy: Your client should understand the basic framework: medications are dispensed on a lien basis, meaning no upfront payment is required, and the lien balance is resolved at settlement. The client does not need to justify pricing — that is the pharmacy's role — but they should not appear ignorant of the arrangement.

[!TIP] Prepare a one-page medication summary for each deposition witness that lists each medication, the prescribing diagnosis, the date first prescribed, and the prescribing physician. This document serves as both a preparation aid and a potential exhibit.

4. Compliance: "Did You Take Every Dose as Prescribed?"

Defense attorneys love compliance gaps. If fill records show a 45-day gap between refills on a medication prescribed for daily use, the defense argues the medication was not truly necessary — if it were, the plaintiff would not have gone without it.

Preparation strategy: Review fill records for gaps and prepare explanations. Common legitimate reasons include: insurance transitions, pharmacy changes, temporary symptom improvement that the prescriber acknowledged, and financial barriers that the lien arrangement resolved. LienScripts generates a MERIT (Medication Evaluation & Rationale for Injury Treatment) report for every case, providing pharmacist-signed documentation for demand packages that also addresses compliance patterns.

Preparing the Treating Provider

When the prescribing physician or nurse practitioner is deposed, defense counsel will probe whether the provider independently determined medical necessity or simply continued prescriptions requested by the patient or suggested by the attorney's office.

Key preparation points for the provider:

• Independent clinical judgment: The provider should be prepared to testify that each prescription was based on their clinical assessment, documented in the medical record at each visit
• Dosage escalation rationale: If dosages increased over time, the provider should explain the clinical basis — worsening symptoms, inadequate pain control at lower doses, or progression of the underlying injury
• Brand vs. generic decisions: If brand-name medications were prescribed, the provider should articulate why — formulary limitations, clinical non-interchangeability, or patient-specific factors

Using MERIT Documentation in Deposition Preparation

The LienScripts MERIT report serves as a comprehensive deposition preparation document because it addresses each attack vector in a single pharmacist-authored narrative:

1. Causation — MERIT ties each medication to specific accident-related diagnoses documented in treating physician records
2. Medical necessity — Clinical rationale for each medication, including mechanism of action and standard-of-care references
3. Compliance context — Dispensing timeline with clinical notes explaining any gaps or changes
4. Pricing framework — Professional pharmacy services documentation supporting the lien balance

As Amar Lunagaria, PharmD, LienScripts' Chief Pharmacist explains, "The MERIT report is designed to be the single document that answers every question defense counsel will ask about pharmacy records — if your witness has reviewed the MERIT before deposition, they are prepared for 90% of the pharmacy-related questioning."

[!KEY] Request MERIT documentation from LienScripts before any deposition involving pharmacy records — it provides the clinical narrative framework that both plaintiff and treating provider witnesses need to testify confidently.

Pre-Deposition Checklist for Pharmacy Records

1. Obtain complete pharmacy fill history (all pharmacies, not just lien pharmacy) going back 24 months pre-accident
2. Identify any medications appearing in both pre- and post-accident periods and prepare causation explanations
3. Review fill dates for compliance gaps and prepare explanations for each gap
4. Ensure your client can articulate, in plain language, what each medication treats and which injury it addresses
5. Request MERIT documentation from LienScripts and review it with your client
6. Prepare a medication timeline exhibit showing accident date, first prescription dates, and dosage changes
7. Coordinate with the treating provider to ensure their deposition testimony aligns with the medical record documentation

Common Defense Exhibits to Anticipate

Defense counsel will typically prepare these pharmacy-related exhibits for deposition:

• Pre-accident pharmacy printout — highlighting any medication overlap
• Fill gap timeline — showing periods without refills
• Generic equivalent pricing — comparing brand costs to generic alternatives
• Pharmacy benefit explanation — showing the plaintiff had insurance coverage available

Prepare counter-exhibits or counter-testimony for each of these. The pharmacy fill history is a factual document — its interpretation is where preparation matters.
