Treatment Gap Documentation: How to Identify and Record Medication Gaps in PI Cases

James Wong — Founder & Pharmacist, LienScripts | December 16, 2025 | 8 min read

Insurance adjusters use treatment gaps to argue that a client's injuries were not as serious as claimed. When those gaps involve prescription medications, the impact on settlement value is compounded. This guide explains how to identify, explain, and document medication treatment gaps to protect your client's case.

Why Treatment Gaps Are a Defense Weapon

A treatment gap — a period during which a client stops receiving medical or pharmaceutical care — is one of the most commonly cited bases for reducing PI settlement valuations. The argument from the defense is simple: if the injury were really as severe as the client claims, they would have continued treatment without interruption.

For prescription medications specifically, gaps are even more visible than gaps in other treatment categories. Every fill is timestamped in a pharmacy record. A period of 60, 90, or 120 days without fills stands out clearly on the pharmacy record and will not go unnoticed by an experienced adjuster or defense attorney.

The solution is not to pretend gaps don't exist — it is to document the reason for every gap and provide that documentation alongside the pharmacy records.

[!KEY] A timestamped pharmacy record makes medication gaps impossible to hide — every 30-, 60-, or 90-day gap will be found by the adjuster, so proactive documentation and explanation in the demand narrative is the only effective strategy.

Types of Treatment Gaps and Their Causes

Gaps in prescription medication fills are rarely evidence of recovery. They most commonly result from:

Prior authorization delays. Many medications — particularly specialty drugs like CGRP inhibitors, Spravato, or compound preparations — require prior authorization from an insurer before they can be dispensed. The prior auth process can take days to weeks. During that time, no fills occur, creating a gap in the pharmacy record.

Prescription lapses. Prescriptions expire. If a client runs out of a prescription without a scheduled follow-up, there may be a gap while they wait for a new appointment and a new script. This is particularly common for patients who are difficult to schedule or who have transportation challenges.

Insurance transitions. When a client loses health insurance (e.g., job change, divorce, aging off a parent's plan), prior prescription coverage may stop and a lien arrangement may begin. The period of transition can create a gap.

Provider changes. When a client switches treating physicians or specialists, there is often a period without prescriptions while the new provider reviews the case, orders imaging, and determines a treatment plan.

Out-of-pocket cost barriers. Some clients on lien arrangements miss fills because they are uncertain whether the lien covers a new medication or worry about increasing the lien balance. This gap reflects financial concern, not recovery.

Actual improvement — temporarily. In some cases, a client genuinely has a period of reduced symptoms (e.g., following a cortisone injection or a successful therapy course) before pain returns. This is a legitimate gap but requires documentation to explain the later return to treatment.

Identifying Gaps in Pharmacy Records

The simplest way to identify medication gaps is to review the pharmacy dispense history chronologically. Request a complete fill history from LienScripts and organize it by medication and date.

For each medication, look for:

• Gaps greater than 30 days between consecutive fills (for daily-use medications, 30 days without a fill is notable)
• Gaps greater than 90 days (significant; will draw adjuster attention)
• Periods where one medication was discontinued and a different one started (may indicate a therapeutic change, not a recovery)
• Gaps at the beginning of the treatment record (may indicate the client was on a prior-lien source before enrollment)

Create a timeline: injury date → first prescription → any gaps and their duration → current status.

Documenting the Explanation for Each Gap

For every significant gap (30+ days), obtain documentation explaining it. Acceptable documentation includes:

Where documentation is not available, a brief declaration from the client explaining the gap can serve as supporting evidence in the demand package.

[!KEY] Each gap cause requires different supporting documentation — a prior authorization delay needs the PA timeline from LienScripts, a prescription lapse needs the prescriber's records, and a provider change needs both the discharge note and the first appointment record from the new provider. Matching the right documentation to each gap is essential.

[!TIP] For every significant gap in a client's pharmacy record, obtain documentation explaining it before building the demand — a well-documented gap explanation is far more effective than an unexplained gap that an adjuster can exploit.

Presenting Gap Documentation in Your Demand

Do not ignore gaps in your demand package — they will be found by the adjuster. Instead, address them proactively.

In the pharmaceutical narrative section of your demand:

1. Acknowledge the gap by date and duration.
2. Provide the documented explanation.
3. Explain why the gap does not indicate recovery or a break in causation.

Example narrative language:

"From [date] to [date], there is a [X]-day gap in plaintiff's pharmacy records for [medication name]. This gap reflects a prior authorization delay during which the prescribing provider, Dr. [Name], submitted an authorization request on [date], which was approved on [date]. Documentation of this delay is attached as Exhibit [X]. The gap does not reflect a break in clinical need or a period of recovery."

Coordinating with the Treating Provider

The most effective treatment gap documentation comes from the treating physician. When gaps are identified, contact the treating provider and request:

• A clinical note documenting the reason for the gap (if it resulted from a clinical decision)
• A statement confirming that the client's need for medication continued throughout the gap period
• Any prior authorization correspondence in the provider's file

Physicians who provide lien-based care are typically familiar with this documentation need and will cooperate.

Key Takeaway

Treatment gaps in pharmacy records are a predictable defense argument — and a preventable one. Identify gaps during case preparation, document the reason for each gap with supporting records, and address gaps proactively in your demand narrative. A well-documented gap explanation is far more effective than an unexplained gap that an adjuster can exploit. LienScripts can provide fill history and prior authorization records to support this process.

[!KEY] Proactively acknowledging and explaining a medication gap in the demand narrative is a stronger position than hoping the adjuster overlooks it — adjusters are trained to find gaps, and a well-explained gap with supporting documentation is far less damaging than an unexplained one.
