Three mechanics that make a moderate injury look like a serious one on paper.
Soft tissue claims in private passenger auto no longer behave like small claims. Three mechanics drive the change: letters of protection, treatment stacking, and the widening gap between billed and paid medical expenses.
The soft tissue claim stopped being a small claim
A rear-end collision at 12 mph used to produce a predictable file. Emergency room visit, a cervical strain diagnosis, six weeks of physical therapy, a demand around four figures. That file still exists. It is no longer the file that drives the loss ratio.
Private passenger auto bodily injury severity has moved faster than the treatment that supposedly explains it. Bodily injury claims reached one in four auto physical damage claims by 2025. They also accounted for 52.3 percent of the combined dollars paid across the two claim categories, up from 44.4 percent in 2022. The average personal bodily injury payout rose 21 percent over two years and passed $30,000 per claim. Over the same stretch, physical damage claim frequency fell 12.6 percent. Bodily injury frequency rose 4 percent.
Fewer crashes. More injury claims. Much larger injury claims.
The gap is not medical inflation. Average third-party medical expenses recorded during claim evaluation rose to $32,300 in the first quarter of 2026, from $24,300 in the first quarter of 2023. That is roughly a third in three years. General medical care costs did not move anywhere near that fast over the same period. Something is adding cost to the file that is not care.
Three mechanics explain most of it. Letters of protection. Treatment stacking. The distance between billed and paid. They interact. A file with all three looks, on paper, like a serious injury. It is often a moderate injury wrapped in financial structure.
Mechanic one: the letter of protection
A letter of protection is an agreement in which a provider treats a claimant now and defers billing until the case resolves. Florida's statute defines it as any arrangement by which a provider renders treatment in exchange for a promise of payment from a judgment or settlement. The definition covers the arrangement whatever the document is called. The name on the paper does not matter. The economics do.
Why the price changes when nobody pays at the time of service
Under a health plan, a provider bills a chargemaster rate. That is the provider's list price, before any discount. The provider then accepts a lower contracted rate. The contracted rate is the real price.
Under a letter of protection, no contract sets the price. The provider bills the chargemaster rate, or more, and waits.
That receivable is an asset. Providers frequently sell it. A factoring company buys the account for cash now, at a discount below face value, and waits for settlement. The discount is the market speaking. If a provider sells a $40,000 receivable for $14,000, the market has priced the care at $14,000. The demand package still says $40,000.
What an adjuster should be able to see
Two states now make that visibility a legal entitlement rather than a negotiating win.
Florida requires a claimant asserting letter of protection medical expenses to disclose five things. The letter itself. Itemized bills coded to CPT or HCPCS. Whether the claimant had health coverage at the time of treatment. The identity of whoever referred the claimant to the provider. And, if the receivable was sold, the name of the factoring company and the dollar amount it paid.
Georgia followed in 2025. Senate Bill 68 makes the same category of information relevant and discoverable. That covers the agreement, the itemized services with charges and billing codes, the amount of any receivable sold to a third party, and the identity of the referring individual.
The referral question is the one adjusters underuse. A claimant who found a surgeon through their primary care physician is on a medical pathway. Compare that with a claimant referred to a surgeon by counsel, treated under a letter of protection, whose receivable then sold at a steep discount. That claimant is on a financial pathway. Both files may contain the same MRI. They do not carry the same value.
Mechanic two: treatment stacking
Treatment stacking is the accumulation of overlapping modalities on a single soft tissue diagnosis. Each new modality adds billing without changing the clinical picture.
The pattern has shifted. A soft tissue file once ran eight to twelve weeks of physical therapy. Files now move toward steroid injections, platelet-rich plasma therapy and shockwave therapy.
Those additions raise the billed total sharply. They rarely come with documented functional change.
The three signatures of a stacked file
Parallel rather than sequential care. Legitimate escalation follows failure. Therapy runs, the patient plateaus, the record says so, and the next step follows. In a stacked file, chiropractic, physical therapy and pain management run at the same time. They often share one referral source, with no documented plateau between them.
Static findings under escalating treatment. Compare the range of motion measurements and pain scores at week two against week sixteen. Unchanged or absent numbers, alongside a growing modality list, mean the record is describing billing rather than a clinical course.
Gaps that reopen. A claimant treats for three weeks, disappears for four months, then resumes an intensive course shortly before the demand. The gap is evidence. It usually means symptoms resolved. Resumed treatment after a long silence deserves a specific explanation in the records, particularly under a letter of protection.
The part that is easy to get wrong
Stacking is a pattern, not a verdict. Some claimants genuinely need escalating care. Some gaps reflect transport problems, caregiving duties or cost, not recovery.
The point is not to score the file against a template. The point is to make the treatment timeline visible enough that the adjuster can see what the record supports. Then the adjuster can say so in a demand response, page by page, with a citation attached.
Mechanic three: billed versus paid
The third mechanic decides what the first two are worth.
If the venue admits only amounts actually paid, a $40,000 letter of protection bill sold for $14,000 is worth arguing about. If the venue admits the billed amount, the same file carries $40,000 of hard specials into every general damages multiplier the plaintiff applies.
The rules are moving, and they are not moving together
- Florida. What the jury may consider: Past medical expenses: amount actually paid only, regardless of payment source. Applies to: Actions under Fla. Stat. s. 768.0427.
- Georgia. What the jury may consider: Both amounts charged and amounts actually necessary to satisfy those charges. Applies to: Causes of action arising on or after the SB 68 effective date.
- Illinois. What the jury may consider: Full billed amount, under the collateral source rule. Applies to: Current practice; no comparable statutory reform.
Florida limits past medical expense evidence to the amount actually paid. For future expenses and unpaid charges, the statute sets reference points. For an uninsured claimant, that is 120 percent of the Medicare reimbursement rate. Where no Medicare rate exists, it is 170 percent of the applicable state Medicaid rate.
Georgia's Senate Bill 68 lets juries consider both the amounts charged and the amounts actually necessary to satisfy those charges. The medical damages provision applies to causes of action arising on or after the effective date. A carrier's Georgia inventory is therefore split by accrual date for years.
Other states still let the full billed amount reach the jury. Practice varies widely by state, and Illinois remains a billed jurisdiction. A plaintiff there may present the full billed amount even where a payer settled the account for far less.
For a regional carrier writing across five or six states, the consequence is direct. The same medical record produces materially different exposure depending on where suit is filed. A single national evaluation template will misprice files at both ends. It overvalues in paid states and undervalues in billed states. The undervaluation is the one that turns into a trial.
What the file has to prove before you can argue value
Evaluation arguments fail on evidence, not on theory. Three questions decide whether an adjuster can hold a number.
- Is the billing traceable to a coded service on a dated page? A demand summary total is not evidence. An itemized, coded bill matched to a treatment note on a specific date is. Where a statute already entitles you to the coded itemization, ask for it in writing. Note the absence if it does not arrive.
- Does the clinical record show change? Escalation without documented functional change is the strongest argument against a stacked total. It requires someone to read the measurements across the full chronology, not the first and last visit.
- Who arranged the care, and who owns the receivable? In Florida and Georgia, both answers are discoverable. Everywhere else, they are still worth asking for. The refusal itself tells you something.
None of this is new to an experienced bodily injury adjuster. The constraint is volume. A contested soft tissue file now runs several hundred pages across multiple providers, and the answers are scattered across them. An adjuster with 90 seconds per document reads the demand summary and the final bill, because that is what fits.
Building the discipline at mid-market scale
The largest carriers are addressing this with internal engineering teams. That route needs a data science function, a document platform and several years. Most regional carriers do not have that, and do not need it.
A mid-market program needs something narrower:
- A reliable treatment chronology built from the raw file, not from the demand summary.
- A flag when modalities overlap without a documented plateau.
- A flag when a treatment gap reopens close to the demand.
- The letter of protection and referral evidence pulled to the front of the file.
- Every one of those outputs linked to its source page, so the adjuster verifies it before using it in a negotiation.
The file should read the same way across the desk, so two adjusters value it the same way. That consistency is the point of automated bodily injury claim file review, and it is what amaise builds toward.
Two constraints matter more than the feature list. The output must be checkable. An unsourced conclusion is not usable in a demand response, and it carries risk in litigation. And the decision stays with the adjuster. A tool that ranks a file without showing its work moves risk rather than removing it.
That argument applies upstream of trial as well. Soft tissue files rarely produce the headline awards. They feed the same dynamic: an inflated specials figure, an unchallenged record, and a defense position built too late. Preparation, not posture, is what changes the number, as the CLM Focus conference panel on stopping nuclear verdicts before trial set out. The same logic applies to the ordinary file. Get the medical chronology right early, and the negotiation starts from evidence rather than from the demand package's arithmetic.
The cost of treating these as small claims
Legal system abuse and inflation together added between $91.6 billion and $102.3 billion to personal auto liability losses and defense costs over the past decade. That is 8.7 to 9.7 percent of booked losses, according to a Triple-I and Casualty Actuarial Society analysis published in October 2025. Across liability lines the range reaches $231.6 billion to $281.2 billion. The analysis is blunt about the driver. Severity, not frequency, is moving losses, and average cost per claim has far outrun economic inflation.
Very little of that total came from catastrophic injuries. It came from a large volume of ordinary files. The specials figure went unexamined. The treatment timeline went unread. The gap between billed and paid went unargued. Soft tissue claims are where severity is manufactured, one moderate file at a time.
The carriers that price these correctly are not the ones with the most aggressive reserving posture. They are the ones whose adjusters can see the whole treatment history. Those adjusters know who arranged the care, know what the receivable actually sold for, and know which of those facts their venue will let them use. Across motor liability claim files, that work starts with the chronology and moves outward from there.
Key takeaways
- Bodily injury claims reached one in four auto physical damage claims by 2025 and 52.3% of the combined dollars paid, up from 44.4% in 2022, while physical damage frequency fell 12.6%.
- A letter of protection removes the contracted rate that normally sets a medical price, so the billed total reflects list price rather than market price. The discount a factoring company pays for the receivable is the market price.
- Treatment stacking shows three signatures: parallel rather than sequential care, static clinical findings under escalating treatment, and treatment gaps that reopen shortly before the demand.
- Whether the venue admits billed or paid amounts decides what the first two mechanics are worth. Florida, Georgia and Illinois now sit in three different positions, so a single national evaluation template will misprice files.
- Severity in private passenger auto is built from a large volume of ordinary files where the specials figure went unexamined, not from catastrophic injuries.
