What Is the Serious Injury Threshold to Sue After a Car Accident in Massachusetts?

Massachusetts is a no-fault car insurance state. That means your own Personal Injury Protection (PIP) coverage pays your initial medical bills and a portion of lost wages regardless of who caused the crash. To step outside the no-fault system and sue the at-fault driver for full pain-and-suffering damages, your injuries must meet a statutory “serious injury” threshold defined in M.G.L. c. 231, sec. 6D. If your injuries cross that threshold, you can file a tort claim against the responsible driver. If they do not, your recovery is generally limited to PIP benefits.

What the Massachusetts No-Fault System Means for Injury Victims

One large exception belongs up front. The threshold described in this article is a feature of the PIP system, and motorcycles sit outside that system, so a motorcycle rider’s claim is not gated by it in the same way. What that changes for an injured rider is set out in Massachusetts motorcycle accident law.

When you are hurt in a Massachusetts car accident, the no-fault system is the first layer of coverage. Your own auto insurance must include Personal Injury Protection (PIP) of at least $8,000. PIP pays 80 percent of your reasonable medical expenses and 75 percent of lost wages up to the $8,000 cap, without any showing of fault.

PIP is fast but limited. An $8,000 cap does not begin to cover the cost of a serious orthopedic injury, a traumatic brain injury, or a spinal injury requiring surgery. The tort threshold exists to let seriously injured people pursue full compensation from the at-fault driver’s liability insurance, including damages for pain and suffering that PIP never covers.

Answer Capsule

To sue the at-fault driver for pain and suffering after a Massachusetts car accident, you must clear the “serious injury” tort threshold set by M.G.L. c. 231, sec. 6D. The threshold is met in one of two ways. First, your medical expenses (net of PIP reimbursement) exceed $2,000. Second, your injury falls into one of the five categories the statute enumerates, regardless of the dollar amount: death, loss of a body member, permanent and serious disfigurement, a loss of sight or hearing of the kind described in paragraphs (a) to (g) of M.G.L. c. 152, sec. 36, or a fracture. If either prong is satisfied, you may pursue a tort claim for full compensatory damages, including pain and suffering. If neither prong is met, your recovery is limited to PIP and property-damage benefits.

The Two-Prong Threshold Under M.G.L. c. 231, sec. 6D

Prong One: The Medical Expense Dollar Threshold

The most commonly triggered prong in everyday car accident cases is the dollar threshold. If your reasonable and necessary medical expenses, after subtracting amounts paid by PIP, exceed the statutory minimum, you have the right to bring a tort claim.

What counts toward the threshold:

• Emergency room charges
• Diagnostic imaging (X-rays, MRI, CT scans)
• Specialist consultations and follow-up visits
• Physical therapy and chiropractic treatment (if medically necessary)
• Surgery and hospitalization
• Prescription medications directly related to the injury

What generally does not count toward the threshold:

• Amounts paid by PIP
• Expenses not causally related to the accident
• Treatment the insurer can show was unnecessary

In practice, many moderate car accident injuries involving emergency care, imaging, and a course of physical therapy cross the $2,000 net threshold relatively quickly. The challenge is often documentation, not the dollar amount itself.

Prong Two: Enumerated Serious Injury Categories

Even if medical expenses are below the dollar threshold (for example, where PIP covered most costs), you can still bring a tort claim if your injury falls within the statute’s enumerated categories:

• Death resulting from the accident
• Fracture of a bone, including fractures that heal without surgery
• Loss of a body member
• Permanent and serious disfigurement, such as significant facial scarring
• Loss of sight or hearing of the kind described in paragraphs (a) to (g) of M.G.L. c. 152, sec. 36

That list is complete. Section 6D allows pain and suffering damages “only if” the expenses exceed two thousand dollars “unless such injury, sickness or disease (1) causes death, or (2) consists in whole or in part of loss of a body member, or (3) consists in whole or in part of permanent and serious disfigurement, or (4) results in such loss of sight or hearing as is described in paragraphs (a), (b), (c), (d), (e), (f) and (g) of section thirty-six of chapter one hundred and fifty-two or (5) consists of a fracture.” Loss of a bodily function is not on it. That phrase belongs to the workers compensation schedule in M.G.L. c. 152, sec. 36, and treating it as a sixth exception to the motor vehicle threshold is a common error rather than the law.

The enumerated-injury prong is particularly important for accident victims whose PIP absorbed most of the medical costs but who suffered a fracture, significant scarring, or other lasting physical consequence. In those cases, the value of the tort claim, particularly the pain-and-suffering component, can substantially exceed what PIP provided.

What You Can Recover Once You Cross the Threshold

Once the serious injury threshold is met, you may pursue a full tort claim against the at-fault driver. Recoverable damages include:

Economic damages:

• All past and future medical expenses related to the injury, beyond what PIP covered
• Past and future lost wages and loss of earning capacity
• Out-of-pocket expenses (transportation to medical appointments, home care, assistive equipment)

Non-economic damages:

• Pain and suffering, past and future
• Loss of enjoyment of life
• Emotional distress
• Loss of consortium for a spouse

Non-economic damages are uncapped in Massachusetts personal injury tort cases. This is a critical distinction from the PIP-only track: PIP never pays pain and suffering at all.

The PIP Coverage Minimum and How It Relates to the Threshold

Massachusetts requires every registered vehicle to carry PIP coverage of at least $8,000 under M.G.L. c. 90, sec. 34A. PIP is “first-party” coverage, meaning it comes from your own insurer, not the at-fault driver’s insurer.

PIP pays first. Once your out-of-pocket medical expenses (after PIP and any health insurance) cross the $2,000 net threshold, you can turn to the at-fault driver’s bodily injury liability coverage. For a motor vehicle liability policy issued or renewed on or after July 1, 2025, M.G.L. c. 90, sec. 34A sets that floor at “not less than $25,000 on account of injury to or death of any one person” and, subject to that per person limit, “not less than $50,000 on account of any one accident resulting in injury to or death of more than one person”. St. 2024, c. 275 raised those figures from the older twenty and forty thousand dollar minimums, which still governed policies written before that date for the remainder of their term.

In a serious injury case, the at-fault driver’s minimum limits are often inadequate. The firm reviews all available coverage sources, including the client’s own underinsured motorist (UIM) coverage, umbrella policies, and any employer or commercial policies that may apply.

Common Situations Where the Threshold Is Contested

Insurance companies have a direct financial incentive to argue that your injuries do not meet the serious injury threshold. If they succeed, they eliminate the pain-and-suffering component of your claim entirely.

Soft-tissue injuries: Sprains, strains, and muscle tears generally do not fall into the enumerated categories. For soft-tissue cases, the dollar threshold is the path to tort recovery, and the insurer will scrutinize every medical bill for necessity and causation.

Fractures the insurer disputes: Some insurers argue that a hairline fracture or a fracture confirmed only by one imaging study does not satisfy the “fracture of a bone” category.

Injuries that improved quickly: A claimant who suffered a fracture but made a full and rapid recovery still crossed the threshold at the time of injury. The defendant cannot retroactively argue the threshold was not met because the outcome was good.

Pre-existing conditions: Insurers argue that a prior back injury or pre-existing degeneration means the accident did not cause the “serious injury.” This is a causation argument, not a threshold argument, but it is often raised together.

An attorney who knows how Massachusetts courts assess these issues can advise whether your injuries meet the threshold and how to document them effectively.

Why the Threshold Makes Documentation So Important

Because the dollar threshold is the most common path, the way your medical treatment is documented in the weeks and months after the accident directly affects whether you have a tort claim at all.

Steps that protect your threshold position:

1. Seek care at an emergency room or urgent care immediately after the accident, even if you feel “okay.” Many soft-tissue and orthopedic injuries worsen in the 24 to 72 hours after impact. Delayed treatment creates a causation gap that insurers exploit.
2. Follow your doctor’s treatment plan completely. Gaps in treatment give the insurer grounds to argue your injuries resolved or were not serious.
3. Get all recommended imaging. An MRI that confirms a disc herniation, nerve impingement, or fracture can be the difference between a PIP-only claim and a full tort recovery.
4. Track every expense. Keep receipts, billing statements, and explanation-of-benefits forms from your health insurer and PIP carrier. Your attorney needs the net-of-PIP medical expense total to evaluate your threshold position.
5. Do not give a recorded statement to any insurer before speaking with an attorney. Recorded statements are used to argue that your injuries were minor and that the threshold was not met.

Frequently Asked Questions

Q: What is the serious injury threshold in Massachusetts car accident cases?

A: Under M.G.L. c. 231, sec. 6D, the threshold is met if your net medical expenses exceed $2,000 (after PIP) or if you suffered one of the five injuries the statute enumerates: death, loss of a body member, permanent and serious disfigurement, a loss of sight or hearing of the kind described in paragraphs (a) to (g) of M.G.L. c. 152, sec. 36, or a fracture. Crossing the threshold allows you to sue the at-fault driver for pain and suffering, which PIP never covers.

Q: Does my injury have to be permanent to cross the threshold?

A: Not necessarily. A bone fracture crosses the threshold whether or not it causes permanent limitation. The dollar threshold ($2,000 net of PIP) is also met based on the amount spent on necessary treatment, not on permanent impairment. Permanent impairment is relevant to the value of your damages, but it is not required to trigger the right to sue.

Q: What if my medical bills were mostly covered by PIP and I am below the $2,000 net threshold?

A: If PIP absorbed most of your costs and your injuries do not fall into the enumerated serious-injury categories, your recovery is typically limited to PIP and property-damage benefits. This is one reason the threshold matters so much: it determines whether a pain-and-suffering claim exists at all. Call Jim Glaser Law at (617) JIM-WINS to confirm your threshold position before concluding you have no further claim.

Q: Can I recover pain and suffering from PIP?

A: No. PIP covers medical expenses and a portion of lost wages only. It does not cover pain, suffering, emotional distress, or loss of enjoyment of life. Those damages are only available if you bring a tort claim against the at-fault driver, which requires crossing the serious injury threshold.

Q: What if the at-fault driver had only the minimum insurance limits and my damages are more?

A: You may have a claim against your own underinsured motorist (UIM) coverage, which covers the gap between the at-fault driver’s limits and your actual damages. The compulsory bodily injury floor for a policy issued or renewed on or after July 1, 2025 is “not less than $25,000” for one person and “not less than $50,000” for one accident involving more than one person under M.G.L. c. 90, sec. 34A, and in a serious case that is consumed quickly. Jim Glaser Law reviews all available coverage sources in every case, including UIM, umbrella policies, and employer commercial policies.

Q: The insurance adjuster told me my injuries are not serious enough to sue. Is that final?

A: No. The adjuster works for the insurance company, not for you. Their threshold assessment is a negotiating position. Call Jim Glaser Law at (617) JIM-WINS for an independent evaluation. The firm will review your medical records and billing to determine whether the threshold is met and whether the insurer’s position is accurate or is being used to suppress your claim.

Q: Is Jimmy Knows AI giving me legal advice?

A: No. This article provides general Massachusetts legal information. It is not legal advice for your specific situation. Call Jim Glaser Law at (617) JIM-WINS for advice about your particular claim.
