What Is a Grid Settlement and How Does It Work?

A grid settlement is a preset payment table used to resolve mass litigation: instead of negotiating each claim individually, a matrix assigns dollar amounts based on fixed variables like injury type, severity, and length of exposure. If your case falls into a particular row and column, that cell tells you what the settlement will pay. Grid settlements are how thousands of claims in pharmaceutical, product liability, and environmental contamination cases get resolved without individual trials.

What the Grid Actually Looks Like

The structure is literal. One axis tracks how badly you were harmed. The other tracks something that ties your harm to the defendant, usually duration or extent of exposure. Where the two meet, a number is already written.

The Camp Lejeune water contamination settlement is a clean illustration. The Department of Justice published an Elective Option Grid with two axes: injury tier and exposure duration. Tier 1 covers diseases where federal researchers found “sufficient” evidence of a causal link to the contaminated water — kidney cancer, liver cancer, non-Hodgkin lymphoma, leukemia, and bladder cancer. Tier 2 covers diseases with weaker but still meaningful evidence, including Parkinson’s disease and multiple myeloma. Exposure is split into three columns: 30 to 364 days, one to five years, and more than five years.

The resulting payments:

  • Tier 1, 30–364 days: $150,000
  • Tier 1, 1–5 years: $300,000
  • Tier 1, more than 5 years: $450,000
  • Tier 2, 30–364 days: $100,000
  • Tier 2, 1–5 years: $250,000
  • Tier 2, more than 5 years: $400,000

Claims involving a qualifying injury that resulted in death receive an additional $100,000, making the maximum payout $550,000.1U.S. Department of Justice. Public Guidance on Elective Option for Camp Lejeune Justice Act A claimant diagnosed with bladder cancer who lived at Camp Lejeune for three years lands on the Tier 1 row, the one-to-five-year column, and receives a $300,000 offer. No haggling. No subjective valuation of pain and suffering. The grid does the work.

What Determines Where You Land on the Grid

Every grid is tailored to its litigation, but the same variables show up again and again. Knowing what drives placement tells you what documentation matters most.

  • Injury type or diagnosis. The biggest single driver of value. A pharmaceutical grid might distinguish liver damage from kidney failure from cardiac events. The Roundup herbicide settlement sorted claimants into nine tiers partly based on whether their non-Hodgkin lymphoma was fast-growing or slow-growing.
  • Injury severity. Some grids split the same diagnosis into mild, moderate, and severe categories. The 3M military earplug settlement created separate payment levels for slight hearing loss (15 dB loss in at least one frequency), mild hearing loss (20–35 dB), and moderate or greater hearing loss (40+ dB).
  • Duration or extent of exposure. How long you used the product, lived near a contamination site, or took the medication. Longer exposure generally pushes you into higher-value cells.
  • Age at diagnosis. Younger claimants sometimes receive higher valuations because they face more years of living with the condition and greater lifetime economic losses.
  • Strength of documentation. Medical records, purchase receipts, employment records, and similar evidence tying your injury to the defendant’s product. Some grids build in bonuses for well-documented claims and reductions for claims supported only by self-reporting.

Not every grid uses every factor. Simpler grids run on two variables. More complex ones layer additional scoring on top of initial tier placement, awarding points for treatment history, prior legal actions, and corroborating records that are then tallied into a final dollar figure.

How Your Claim Moves From Filing to Payment

Once a grid settlement is finalized and approved, a claims administrator takes over the practical work. The process has more friction than most claimants expect.

  • Registration. You or your attorney submit a claim form identifying your injury, exposure history, and basic personal information.
  • Documentation. You provide supporting evidence — medical records confirming your diagnosis, proof of exposure such as employment records or proof of residence, and sometimes pharmacy or treatment histories.
  • Review and tier placement. The claims administrator applies the grid criteria and assigns your claim to a specific tier and cell. Administrators use point-based allocation models designed to keep similarly situated claimants consistent.2Epiq Global. Mass Tort Settlement Claims Administration
  • Notice of determination. You receive a letter explaining your tier placement and the corresponding payment.
  • Reconsideration or appeal. If you believe you were placed incorrectly, most settlement agreements let you request reconsideration, submit additional records, or appeal to a special master.
  • Lien resolution and payment. Before funds are released, outstanding liens from Medicare, Medicaid, or private insurers must be addressed. Only then does the administrator issue payment.

Timelines vary widely. Simple settlements with strong documentation can pay out in months. Complex mass torts with hundreds of thousands of claims, disputed medical records, and lien work can stretch past a year. The 3M earplug and Roundup settlements both involved extended processing periods as administrators worked through enormous claim volumes.

Should You Opt Out

Participating in a grid settlement is usually voluntary. Most mass tort agreements include an opt-out window during which you can reject the grid and preserve your right to pursue individual litigation. This is the most consequential decision in the process.

If you opt out, you keep the ability to argue your case is worth more than the grid assigns. Your injuries may be unusually severe, your economic losses may dwarf the grid amount, or you may have evidence that would play powerfully to a jury. The cost is time, expense, and risk. Trials take years, require significant legal fees, and carry the possibility of losing outright.

If you stay in the grid, you accept a set amount in exchange for speed and certainty. For most claimants, especially those whose injuries fall squarely in the middle tiers, that tradeoff is reasonable and the payment arrives far sooner than a trial verdict would. Missing the opt-out deadline usually locks you in permanently.

What Comes Out Before You See Your Payment

The number on the grid is not the number you take home. Several deductions come off the top, and ignoring them can create real legal problems.

Medicare and Medicaid Liens

If Medicare paid for any treatment related to your injury, federal law requires you to reimburse those payments from your settlement. Medicare treats them as “conditional payments,” meaning it covered your care on the condition it gets paid back once someone else foots the bill.3Centers for Medicare & Medicaid Services. Medicare’s Recovery Process The obligation comes from the Medicare Secondary Payer Act, which makes Medicare a secondary payer whenever a liability settlement is involved.4Centers for Medicare & Medicaid Services. Medicare Secondary Payer (MSP) Obligations and Settlements

Medicare will issue a conditional payment letter listing every covered service it believes is related to your case. Review it carefully. It sometimes includes treatments unrelated to the injury at issue, and you have the right to dispute those. Attorney fees and litigation costs factor into the final reimbursement figure before it’s calculated.3Centers for Medicare & Medicaid Services. Medicare’s Recovery Process

Private Health Insurance Liens

If your health insurance is an employer-sponsored plan governed by ERISA, that plan may also have a right to reimbursement from your settlement. Self-funded employer plans in particular have broad authority to enforce subrogation clauses requiring repayment of medical costs the plan covered, and those rights can override state laws that would otherwise limit such recoveries. Courts have recognized that equitable principles can reduce what a plan actually recovers, for example by requiring the plan to share in the attorney fees that made the recovery possible.

Attorney Fees

Most mass tort attorneys work on contingency, taking a percentage of the recovery rather than billing hourly. That percentage commonly runs around one-third, though it varies by firm and can be higher when a case required extensive litigation before settling. Some grid settlements include a court-imposed cap on attorney fees to protect claimants. Your fee agreement should spell out the exact percentage and whether litigation costs like filing fees, expert witness fees, and medical record retrieval come out of your share or the attorney’s share.

How the Payment Is Taxed

How much of your grid payment is taxable depends on what it compensates you for. The IRS draws a hard line between physical injuries and everything else.

Damages received on account of personal physical injuries or physical sickness are excluded from gross income under federal tax law. This applies whether the payment arrives from a verdict or a settlement, and whether it comes as a lump sum or in installments.5Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness Pain and suffering damages tied to a physical injury also qualify for exclusion, as does emotional distress that flows from the physical injury itself.

Several categories of settlement money are taxable regardless of physical injury:

  • Punitive damages. Always taxable. The IRS requires you to report them as “Other Income” on Schedule 1 of Form 1040, even when they arise from a personal physical injury case.6Internal Revenue Service. Settlements — Taxability
  • Interest. Any interest that accrues on your settlement while held in escrow or after judgment is taxable income.
  • Emotional distress without physical injury. Emotional distress is not treated as a physical injury or sickness for tax exclusion purposes. The only exception is that you can exclude amounts up to what you actually paid for medical care attributable to that emotional distress.5Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness
  • Previously deducted medical expenses. If you deducted medical costs in a prior year and your settlement later reimburses those same costs, the reimbursed portion becomes taxable up to the amount you deducted.

Most mass tort grid settlements involve physical injuries such as cancers, organ damage, and hearing loss, so the bulk of the payment is typically excludable. If your settlement agreement allocates any portion to punitive damages or non-physical claims, that portion will be taxed. The IRS generally respects written allocation agreements between the parties when they reflect genuine intent, which is why your attorney should push for clear allocation language during settlement.6Internal Revenue Service. Settlements — Taxability

When the Grid Helps and When It Shortchanges You

Grid settlements exist because they solve a real problem. When thousands of people have similar claims against the same defendant, trying each case individually would take decades and cost everyone involved far more in legal fees than the claims are worth. The grid trades individualized precision for scale and speed. Whether that tradeoff works in your favor depends on where you sit.

Speed is the most obvious benefit. A grid settlement can resolve your claim in months rather than the years an individual lawsuit would take. Predictability matters too. You can look at the grid, assess your documentation, and estimate your payment before you even file. There is no jury variability, no risk of a defense verdict wiping out your claim, and no need to testify or sit through a trial. For claimants with moderate injuries and solid documentation, the grid often delivers fair value with minimal hassle.

The limitations are just as real. The grid treats similar cases similarly, which means it cannot account for the full picture of any one person’s life. If your medical expenses are dramatically higher than average for your tier, the grid won’t reflect that. If you lost a career that paid well above median income, the grid’s standardized economic-loss value won’t capture your actual loss. Grids also compress the high and low ends of the value range. Claimants with the strongest cases, the ones who would likely win large verdicts at trial, tend to receive less from a grid than they would in individual litigation. Claimants with weaker cases often receive more than any jury would give them.

Documentation requirements can create their own barriers. Claimants who received treatment decades ago, or whose medical providers have closed or lost records, may struggle to prove the severity of their injuries. Some grids penalize incomplete documentation with lower tier placements, which puts the heaviest paperwork burden on people whose injuries are oldest.
