Proving past medical expenses in a Texas injury case takes more than adding the amounts printed on bills. The evidence should connect each service to the injury, establish that the care was necessary and the charge reasonable, and identify what amount the law permits the claimant to recover. Under Texas Civil Practice and Remedies Code § 41.0105, recovery of medical or health care expenses incurred is limited to amounts actually paid or incurred by or for the claimant. The provider’s legal right to payment matters; the face amount alone does not settle the issue.
Build the record service by service
Start with an itemized statement for each provider. Identify the date, service, code, units, original charge, contractual adjustment, payment, credit, current balance, and any amount still legally owed. Reconcile those figures to explanation-of-benefits records, remittance advices, patient ledgers, receipts, and provider statements. If the account was transferred, adjusted, assigned, or placed with a collection agency, obtain records showing what happened and who holds the right to collect.
Keep four numbers separate: the amount billed, the amount paid, the amount written off or adjusted, and the amount for which the claimant remains legally responsible. An adjustment is not itself a payment. Nor does a balance on a statement automatically prove the patient owes it. Look at the governing contract, benefit rules, provider agreement, lien or letter-of-protection documents, and any later payment or adjustment. The objective is a traceable ledger, not a large total.
Connect the treatment to the collision
For each service, explain why it belongs in the injury claim. Match the treatment date and body part to the medical history, diagnostic findings, referral, and treating provider’s explanation. Address prior symptoms, later events, gaps in care, and treatment for unrelated conditions where they appear in the record. A billing affidavit does not prove that a collision caused an injury or that a particular service was related to it.
Medical records, imaging, operative reports, prescriptions, therapy notes, and provider testimony can supply different parts of that explanation. The person who can explain why a procedure was medically indicated may not be the person who can establish how the amount was calculated or what the provider remains entitled to collect. Match each witness to the proposition.
Reasonableness and necessity require a foundation
Texas Civil Practice and Remedies Code § 18.001 provides a way to offer evidence about whether a service was necessary and whether its charge was reasonable at the time and place it was provided. The statute requires an itemized statement and an affidavit from the provider or the person in charge of records showing the services and charges. A compliant, uncontroverted affidavit is sufficient evidence to support a finding on those issues, but it is not conclusive and is not evidence of causation.
The statute also permits a qualified counteraffiant to state the basis for controverting the reasonableness or necessity of the charges. In re Allstate Indemnity Co. explains that the procedure does not automatically prevent a party from challenging those issues at trial. Check the current statute and applicable court rules for service requirements and deadlines in the particular case; do not rely on a generic calendar or an old checklist.
Section 18.001 is not a shortcut around § 41.0105. In Haygood v. De Escabedo, the Supreme Court of Texas explained that § 41.0105 limits recovery, and the evidence supporting that recovery, to expenses the provider has a legal right to be paid. The analysis may differ depending on the payment source, provider agreements, liens, and other obligations. Trace the actual account rather than assuming every write-off or unpaid balance has the same legal effect.
Test alternative figures, not just totals
If an opposing expert or auditor offers a lower amount, ask for the records, codes, units, time period, and geographic market behind each adjustment. Does the comparison use the same service and setting? Does it account for the provider’s specialty, acuity, and locality? Can the witness explain the data and methodology, and is that witness qualified to offer the opinion? A spreadsheet total without its inputs is difficult to evaluate.
For example, if a hospital lists a $100,000 charge, a $60,000 contractual adjustment, and a $40,000 payment, those entries should not be presented as if the claimant simply paid or owes $100,000. The ledger must show the source and effect of each entry and whether any amount remains enforceably due. The illustration is not a universal formula: the controlling contracts and payment records determine what those numbers mean.
A practical records checklist
- Itemized bills with service dates, descriptions, codes, units, and provider identity.
- Patient ledgers, payment histories, receipts, credits, refunds, and current balances.
- Insurance explanations of benefits, remittance records, contractual adjustments, and benefit documents.
- Provider contracts, assignments, liens, letters of protection, and documents identifying any right to collect.
- Records supporting the medical reason for each disputed service and its relationship to the claimed injury.
- Any § 18.001 affidavit and counteraffidavit, together with proof of service and the current scheduling order.
- The sources, comparisons, codes, units, and qualifications underlying any alternative valuation.
Organize the material so another person can reproduce the total from the source records. Flag unexplained balances, duplicate entries, conflicting codes, and services that need a causation witness. That work makes the claim easier to evaluate and exposes disputes that need medical or billing testimony before a hearing or trial.
Questions people often ask
Is the amount printed on a bill the recoverable amount? No. The billed charge alone does not establish what was paid, legally incurred, reasonable, necessary, or caused by the event.
Does an affidavit under § 18.001 prove the accident caused the treatment? No. The statute expressly says the affidavit does not prove causation.
Does an uncontroverted affidavit conclusively establish the charge? No. It is sufficient evidence to support a finding on reasonableness and necessity, but it is not conclusive.
What if a provider still shows a balance? Determine whether the claimant is legally responsible for it and what agreements or payment rules govern the account. The balance entry alone does not answer that question.
