MEDICAL & INJURIES
10 legal terms in this category, with plain-English definitions and real-world car accident examples.
Aggravation of Pre-Existing Condition
When a car accident makes an existing injury or medical condition worse. You can still recover damages for the worsening, even though you had the condition before the crash.
You had mild back pain from an old sports injury, but the rear-end collision turned it into a herniated disc requiring surgery. The at-fault driver is responsible for the aggravation.
Independent Medical Examination (IME)
A medical exam requested (and paid for) by the insurance company to get a second opinion on your injuries. Despite the name, the doctor is chosen by the insurer.
The insurance company sends you to their doctor who concludes your injuries are 'minor' and you've reached maximum recovery, directly contradicting your own doctor's findings.
Letter of Protection
A document from your attorney to a medical provider guaranteeing that the provider will be paid from your settlement. This lets you get treatment even if you can't afford it now.
You need an MRI but can't pay the $2,500 out of pocket. Your lawyer sends the imaging center a letter of protection, and they perform the MRI knowing they'll be paid when your case settles.
Lien
A legal claim against your settlement by a healthcare provider, health insurer, or government program that paid for your accident-related medical treatment.
Your health insurance paid $40,000 for your accident surgeries. When you settle for $150,000, your insurer places a lien to recoup that $40,000 from your proceeds.
Maximum Medical Improvement (MMI)
The point at which your doctor determines your condition has stabilized and further treatment won't significantly improve it. This is often when your case value is calculated.
After 8 months of physical therapy for your whiplash, your doctor says you've reached MMI. Your neck will always have some stiffness, but now your attorney can calculate your full damages.
Medical Lien
A legal claim a healthcare provider places against your settlement to ensure they get paid for treatment they provided on credit while your case was pending.
The hospital treated your broken leg and placed a $25,000 medical lien on your case. When you settle for $100,000, the hospital gets their $25,000 off the top.
Pre-Existing Condition
A medical condition you had before the car accident. Insurance companies often try to blame your injuries on pre-existing conditions to reduce your payout.
The insurer argues your back pain is from your old disc bulge, not the crash. Your doctor's records show the bulge was asymptomatic before the accident and now requires surgery.
Soft Tissue Injury
Damage to muscles, ligaments, or tendons rather than bones. These injuries (like sprains, strains, and whiplash) don't show up on X-rays and insurers often undervalue them.
After a fender bender, you develop severe neck and shoulder pain from ligament damage. The insurer offers a lowball settlement because there's no 'visible' injury on imaging.
Traumatic Brain Injury (TBI)
Brain damage caused by a violent blow or jolt to the head during a collision. TBIs range from mild concussions to severe injuries causing permanent cognitive impairment.
Your head strikes the steering wheel during a head-on collision, causing a TBI that leaves you with memory problems, personality changes, and difficulty concentrating at work.
Whiplash
A neck injury caused by a sudden back-and-forth motion of the head, extremely common in rear-end collisions. Symptoms may not appear until days after the crash.
You feel fine after being rear-ended, but two days later you wake up with severe neck stiffness, headaches, and shooting pain down your arm. These are classic whiplash symptoms.
