Settle direct with the adjuster, sign with a contingency firm, or file it yourself in small claims and keep the whole number

A $40,000 settlement is not $40,000, and the gap between the two numbers is where most of the arguing happens. Four things come out of the gross figure before anything reaches you: the contingency fee, the costs the office advanced on your behalf, any hospital lien filed against the recovery, and any repayment claim from the health plan or government program that paid your bills. The order in which those come out changes the arithmetic. So take a hypothetical Oklahoma case, settled before a lawsuit was filed, and work down the page.
The gross is $40,000, paid by the at-fault driver's liability carrier. The fee agreement says one third before suit is filed and forty percent after, which is the common Oklahoma structure, and this case settled after a demand letter, so the fee is $13,333. What a careful reader checks here is not the percentage but the base: whether the fee is calculated on the gross number or on the gross minus advanced costs. On $40,000 with $1,410 in costs, that difference is about $470. It should be spelled out in the contract, and if it isn't, ask before signing.
Case costs in this file come to $1,410: certified medical records from three providers, the crash report, a records retrieval service fee, postage and courier charges, and a $600 narrative report from the treating physician to support the demand. Costs are reimbursements, not compensation to the office, and a closing statement should list each one with a date and an amount you can match to an invoice. Look for two things that shouldn't be there: charges for ordinary overhead like phone lines or office staff time, and interest added to advanced costs. Running total after fee and costs: $25,257.
The emergency room billed $11,200 and filed a hospital lien with the county clerk under Oklahoma's hospital lien statute, 42 O.S. Section 43, which requires the filing and written notice within the window the statute sets after discharge. A lien filed late, filed in the wrong county, or unsupported by notice is vulnerable, and that is the first thing worth checking rather than the balance. Here the lien was valid, and the hospital reduced to $6,000 in exchange for prompt payment out of the settlement. Follow-up orthopedic care and physical therapy were paid by an employer health plan, which asserted a reimbursement claim of $6,400.
Employer plans governed by ERISA can enforce their plan language aggressively, and Medicare's repayment right under the Medicare Secondary Payer Act is stronger still; the Centers for Medicare and Medicaid Services is the federal agency responsible for administering that recovery process. Oklahoma Medicaid, run through the Oklahoma Health Care Authority, has its own statutory claim at 63 O.S. Section 5051.1, with a formula that reduces the state's share to account for the fees and costs of obtaining the money. In this file the plan accepted $4,200, a common-fund reduction reflecting that it recovered nothing on its own. That leaves $15,057.
Before you endorse anything, ask for a written closing statement that shows the gross, each deduction with a payee name, and the net, and ask for copies of the lien reduction letters. Every reduced lien should be confirmed in writing by the lienholder, not summarized over the phone, because a hospital that later says it never agreed to $6,000 can pursue you personally. Confirm the release covers only the parties you intend to release. Confirm that any uninsured motorist claim against your own carrier under 36 O.S. Section 3636 survives, if you have one.
The comparison that matters is not $40,000 with a lawyer against $40,000 without one. Unrepresented, this claim would more likely have drawn an offer somewhere in the high teens, with the $11,200 hospital lien and the $6,400 plan claim both payable at full face value, because nobody would have written the letters that cut them to $10,200 combined. Fifteen thousand dollars in hand, with every medical bill closed out and no lien waiting to surface, is a different outcome from a larger check that quietly owes most of itself to somebody else.
Run your own file the same way. Write the gross at the top, subtract in order, and make each line prove itself.
