Internal Injuries Settlement Calculator

Two crash victims can both be told they have a "lacerated spleen" and end up with claims worth twenty times apart. The difference is what the trauma team had to do. Internal injury value tracks the treatment ladder: observation, then intervention that saves the organ, then removal of the organ, then multi-organ damage with intensive care. Each rung roughly triples the claim.

Reported ruptured spleen averages run $150,000 to $200,000; reported splenectomy results include $375,000, $645,000, and $1,400,000, and a New York multi-organ verdict reached $2,015,000.

Trauma surgeons grade solid organ injuries I through V on the American Association for the Surgery of Trauma (AAST) Organ Injury Scale, from a small subcapsular hematoma to a shattered organ. That grade appears in your CT report and operative notes, and it is the single most useful number for predicting both treatment and claim value. Here is how the commonly injured organs break down.

Spleen: The Most Commonly Ruptured Organ

The spleen sits under the left ribs, bleeds heavily when torn, and is the classic steering wheel and seatbelt injury. Most low-grade splenic injuries are now managed without surgery, which places them in the $30,000 to $100,000 observation tier. When embolization or repair is needed, cases move to roughly $150,000 to $500,000. A full splenectomy changes the claim category entirely: reported averages for ruptured spleen cases run $150,000 to $200,000, but splenectomy results commonly reach $300,000 to $1,000,000 or more because the loss is permanent. Living without a spleen means elevated lifelong infection risk and a permanent vaccination protocol, and insurers pay for permanence.

Liver: The Largest Target in the Abdomen

The liver is the largest solid organ and the other frequent casualty of blunt abdominal trauma. Low-grade lacerations are typically observed; higher grades bleed dangerously and need embolization or operative repair. Reported liver laceration settlements combined with moderate orthopedic injuries have resolved in the $115,000 to $135,000 range, with surgical and high-grade cases climbing well beyond that alongside the treatment tiers above.

Lungs: Pneumothorax and Hemothorax

A punctured lung (pneumothorax) lets air into the chest cavity; a hemothorax fills it with blood. Both usually arrive with rib fractures. A small pneumothorax that resolves under observation sits at the bottom of the range, a chest tube moves the claim to roughly $75,000 to $250,000, and cases involving ventilators, flail chest, or lasting respiratory impairment go higher. The chest tube itself matters to adjusters: it is objective proof the injury was severe enough to require an invasive emergency procedure.

Kidneys, Bowel, and Mesentery

Kidney injuries follow the same observation-to-removal ladder as the spleen, with nephrectomy (kidney removal) cases valued like splenectomies because the loss is permanent and measurable. Bowel and mesenteric injuries are different: they are almost always surgical, because a perforated intestine leaks into the abdomen and becomes life-threatening peritonitis. They are also the signature injury of seatbelt loading, covered next, and their frequent delayed diagnosis is both a medical danger and a claims battleground.

The seatbelt saves your life by stopping your body with the crash instead of the windshield. In a violent enough collision, the belt itself becomes the loading surface, compressing the abdomen against the spine during deceleration. The result is a recognized injury pattern called seatbelt syndrome: a belt-shaped bruise across the abdomen (the "seatbelt sign") with bowel perforation, mesenteric tearing, or solid organ damage underneath.

The numbers are striking. In a published study of crash victims with a seatbelt sign who needed abdominal surgery, 58 percent had small bowel injuries, 39 percent had large bowel injuries, and 39 percent had splenic injuries. That is why trauma protocols treat a belt bruise as a red flag demanding a CT scan rather than a cosmetic finding.

For your claim, delayed diagnosis cuts both ways. It is medically expected, so a diagnosis a day or two after the crash does not break causation, provided the return visit documents the collision. But a victim who never got checked out, then surfaces at the ER a week later with no recorded link to the crash, hands the insurer its causation defense. The pattern to follow is simple: same-day evaluation after any significant collision, and an immediate return the moment symptoms change.

Internal injury claims are unusually evidence-rich: everything that matters is in the hospital record. These are the factors that move the number, roughly in order of weight.

Internal injury claims rarely lose on severity; they lose on gaps. Follow these steps from the day of the crash.

Here is how the treatment tiers play out in practice. These examples are modeled on patterns in actual settlement and verdict data.

The tiers above are the framework. Your specific value depends on which organ was injured, the AAST grade, what the trauma team did, what you permanently lost, your hospital course, and your state.
