What Is a Demand Letter in Personal Injury?

James Wong — Founder & Pharmacist, LienScripts | March 6, 2024 | 6 min read

A demand letter is the formal written communication from a PI attorney to the at-fault party's insurer that opens settlement negotiations. It presents the facts, the injuries, and a damages calculation. Pharmacy records are a critical component of a credible, well-supported demand.

The Opening Move in Settlement Negotiations

Before a personal injury case goes to trial — and before most cases even get to a lawsuit — the plaintiff's attorney sends a demand letter to the defendant's insurance carrier. The demand letter is a formal written communication that presents the case, documents the injuries and damages, and states a specific dollar amount the plaintiff is willing to accept to settle the claim.

A well-written demand letter does more than state a number. It tells a story: the defendant's liability, the plaintiff's injuries, the treatment required, and the full measure of damages the plaintiff suffered. The quality of the demand letter — and the documentation supporting it — directly affects the settlement offer that comes back.

[!KEY] A demand letter is only as strong as its supporting documentation — an LSR and MERIT report attached as exhibits transform pharmacy costs from a bare figure into an undisputable line item in the special damages calculation.

What a Demand Letter Contains

A standard PI demand letter includes the following sections:

Introduction and facts of the incident. A narrative of how the accident occurred — the date, location, circumstances, and the defendant's negligent conduct. This section establishes liability and connects the accident to the plaintiff's injuries.

Injury description. A detailed account of the plaintiff's injuries — the diagnosis, how they have affected daily life, functional limitations, and the severity and duration of pain. This section draws directly from medical records, treating physician notes, and the client's own account.

Treatment narrative. A summary of all treatment received — emergency care, specialist visits, physical therapy, chiropractic, and medication management. For medication-heavy cases, this section is supported by pharmacy records documenting the prescription fill history.

Damages summary. A table or list of all economic damages (medical bills, pharmacy costs, lost wages, future care) and an estimate of non-economic damages (pain and suffering). This is where the pharmacy lien balance appears as a line item.

Settlement demand. The specific dollar amount the plaintiff is demanding to resolve the case, with a deadline for response.

Why Pharmacy Records Belong in the Demand

A demand letter without supporting documentation is an assertion. A demand letter with supporting documentation is a case.

For any case involving prescription medications — which includes most serious PI cases — the pharmacy record is essential supporting evidence for the demand:

It quantifies a specific line item. The pharmacy lien balance from an LSR (Lien Summary Report) gives the demand a specific, verifiable number for pharmaceutical damages. This is far more credible than an estimate or a general reference to "medication costs."

It documents treatment duration. A pharmacy record spanning 14 months of treatment is objective evidence that the injury required 14 months of pharmaceutical management. This duration supports both the special damages figure and the pain and suffering narrative.

It establishes medical necessity. Prescriptions written by treating physicians, with diagnosis codes tied to the injury, demonstrate that each medication was clinically justified — not speculative. This preemptively addresses the adjuster's most common defense.

The MERIT report adds clinical depth. A MERIT report from LienScripts goes beyond the LSR to explain why each medication was prescribed, what it treated, and what clinical outcomes were observed. Attaching a MERIT report as a demand exhibit transforms a list of drug names into a clinical narrative that is difficult to dismiss.

Structuring Pharmacy Costs in the Demand

Pharmacy costs belong in the special damages section of the demand. A clear, professional presentation:

SPECIAL DAMAGES

Emergency/Hospital: $XX,XXX
Physician and Specialist Fees: $XX,XXX
Physical Therapy: $XX,XXX
Pharmacy Lien (see attached LSR, Exhibit A): $XX,XXX
Lost Wages: $XX,XXX
Total Special Damages: $XXX,XXX

GENERAL DAMAGES (Pain and Suffering)

Based on [X] months of treatment requiring the above medications
and ongoing limitations, we demand general damages of $XXX,XXX.

TOTAL DEMAND: $XXX,XXX

What Happens After the Demand Is Sent

The insurance carrier reviews the demand, evaluates the supporting documentation, and responds with either:

• A counteroffer (most common) — a lower amount that opens negotiation.
• An acceptance — the full demand is accepted (rare in complex cases).
• A rejection — the carrier declines to offer anything, or offers nominal amounts.
• A request for additional information — the carrier asks for more documentation before responding.

The demand letter sets the ceiling for negotiations. An adjuster who receives a demand without pharmacy documentation may challenge whether the medication costs are legitimate. An adjuster who receives an LSR and MERIT report attached as exhibits has a much harder time disputing those costs.

[!KEY] The demand letter sets the negotiating ceiling — a poorly supported demand invites a lowball counter, while a demand backed by an LSR and MERIT report forces the adjuster to engage with each documented item rather than challenging the whole.

[!TIP] For Attorneys: Send the demand only after requesting a final LSR from LienScripts confirming the total lien balance through the last dispense date — an incomplete pharmacy record leaves money on the table in the special damages calculation.

Demand Letter Timing

Attorneys typically send demand letters after the client has reached Maximum Medical Improvement (MMI) — the point at which the full extent of damages can be accurately assessed. Sending a demand before treatment is complete risks undervaluing future care needs and may result in a settlement that doesn't fully compensate the client.

For pharmacy-heavy cases, the demand should be sent after requesting a final LSR from LienScripts confirming the total lien balance through the last dispense date.

[!KEY] Sending the demand after MMI and after receiving a final LSR ensures the pharmacy costs in the special damages section are complete and final — a demand that undercounts pharmacy costs because it was sent before the last fill cannot easily be supplemented without weakening the attorney's negotiating posture.

Key Takeaway

A demand letter is the attorney's formal written presentation of the client's case to the insurer. It sets the negotiating ceiling and must be supported by comprehensive documentation — including pharmacy records — to be taken seriously. An LSR and MERIT report from LienScripts provide exactly the documentation needed to make pharmacy costs an undisputable component of the demand.
