Best for: Missed fetal distress claims
In a case published by Miller Weisbrod Olesky, Attorneys At Law, a failure to diagnose fetal distress resulted in brain damage. For a birth injury involving blood-pressure monitoring during delivery, the firm also reports a $13.75 million settlement. Because those cases involve diagnostic and monitoring failures, they support its position here.

Best for: Malpractice-focused representation
Van Wey & Metzler's listed practice centers on medical malpractice and birth injury rather than a broad range of accident claims. Its site shows misdiagnosis work. It also publishes a jury verdict involving failure to manage critically high blood glucose, which resulted in a heart attack and brain damage.

When reviewing treatment dates, a lawyer checks Texas's filing rule: generally 2 years from the breach or completion of treatment or hospitalization. These claims don't have a general discovery rule. Before waiting for more records, ask how that rule affects your claim.
Review the diagnostic history
After describing your symptoms and test results to the lawyer, discuss the later diagnosis. Which records and medical opinions would the firm need to evaluate your claim? Who would handle your file, and how would you pay expenses?
File the complaint
If the firm accepts your claim and moves ahead, find out which defendants it would name in the complaint, then ask how it would meet the filing deadline. For children's claims, some circumstances can change the timing rules. Ask the lawyer to check the relevant dates against your child's age.
Serve the expert reports
After a defendant files an answer (the response to the complaint), Texas requires an expert report and CV for that defendant within 120 days. Your claim faces dismissal with prejudice and fees if you don't meet the report requirement.
Consider resolution
When a settlement is proposed as your claim moves forward, ask the lawyer to explain it and what pursuing a verdict would involve. Non-economic damages in health care liability claims face Texas caps. If the case involves a death, a separate inflation-indexed cap also limits total damages.

A written agreementThe share the lawyer takes, set out before work starts.
If you recover moneyThe agreed share and the case costs come out of it.
If the claim failsNo legal fee on a contingency agreement. Ask about costs.
According to six listed firms, they work on contingency: if the claim fails, there's no attorney fee; otherwise, the lawyer receives a share of a recovery. Don't confuse costs with fees. You'll see costs for medical records and medical opinions, with court fees separate from those. Although Miller Weisbrod Olesky, Attorneys At Law publishes examples of litigation expenses reimbursed from settlements, don't assume every agreement handles those expenses the same way. Before you sign, find out who advances expenses and when they're deducted. If the claim fails, could you owe them? Ask for the fee calculation in writing so you know whether costs are deducted before or after the attorney's share.
Six of the seven listed firms say consultations are free; six also say they take cases on contingency.

Questions to ask a lawyer
1For a diagnostic delay like mine, how many claims have you handled?
2Who would take responsibility for my file?
3Under Texas law, when must I file my claim?
4What's your plan for getting the required expert reports?
5When I have questions, how would you respond and provide updates?
6What's your calculation for the contingency fee and case expenses?
7If there's no recovery, could I still owe case expenses?
8If you decline my case, will you tell me why?
Choosing a misdiagnosis lawyer in Dallas
Rather than starting with a firm's large published verdict, focus on what went wrong with the diagnosis. After explaining the symptoms you reported and when testing happened, give the date you received the diagnosis. Have they handled similar delays? Although a birth injury result can show malpractice work, it won't tell you whether the attorney has handled the medical condition involved in your claim.
Ask who will read your records
When someone answers your intake call, don't assume they're the lawyer who would handle your claim. Who is that lawyer? How would your questions reach them directly? Although several firms here receive praise for updates, some also draw complaints about unanswered calls or cases declined without explanation. Rather than treating a star rating as proof of malpractice experience, use the feedback to shape specific questions.
How would the firm investigate the missed diagnosis and obtain the medical opinions needed for your claim?
Instead of relying on unrelated injury results, request examples of cases involving a similar diagnostic delay.
Where would you meet? While the other listed firms have Dallas offices, Hastings Law Firm's office is in Austin.
If the firm declined your case, would it explain why, and what would happen after that decision?
Filing on time isn't the only procedural hurdle you'll face. After each defendant files an answer, Texas requires an expert report and CV for that defendant within 120 days. If you miss that requirement, dismissal with prejudice and fees follow. How would the firm obtain the report and keep track of each defendant's deadline? For these rules, see the Texas guide.
Read the payment agreement
If a consultation is free, you won't pay for that discussion. Don't take that to mean the firm has accepted your case. If the claim fails under a contingency fee agreement, there's no attorney fee; otherwise, the lawyer receives a share of a recovery. Because expenses are separate, ask who pays for records and medical opinions, then check whether you'd owe those expenses even if there isn't a recovery.
If someone promises you a payout or pushes you to sign before you understand the fee terms, be wary. Don't use published recoveries to predict yours; they describe past cases. Treat this as general information, not legal advice. To understand how the rules apply to your family, speak with a Texas lawyer.
Questions people ask
Which firm leads this Dallas misdiagnosis lawyer list?
Although it's listed here, its office is in Austin, not Dallas; don't use a past settlement to predict your result. Before choosing the firm for your family, find out which lawyer would evaluate what went wrong with the diagnosis. How would you meet with them?
How long do I have to file a misdiagnosis claim in Texas?
You generally must file in Texas within 2 years of the breach, or when treatment or hospitalization ended. No general discovery rule applies to these claims. Although the statute sets a 10-year outer limit, you can't treat that as permission to wait past the ordinary deadline. Which dates control your claim is a question for a Texas lawyer.
Does finding out about the misdiagnosis later restart the deadline?
For health care liability claims, Texas doesn't have a general discovery rule. If you discover a missed condition after treatment ends, that matters: a later diagnosis generally doesn't restart the clock for filing your claim. When speaking with a Texas lawyer, give the original treatment dates and the later diagnosis date. How does that rule affect your claim?
What does a Texas malpractice claim need besides a complaint?
After each defendant files an answer, Texas requires an expert report and the expert's CV for that defendant within 120 days. If you miss that requirement, your claim faces dismissal with prejudice and fees. You can't stop at filing the complaint. How would the lawyer's firm get the medical opinions and reports needed to move your claim forward?
Can I speak with a Dallas malpractice lawyer without paying upfront?
According to the listed firms, six offer a free consultation; six also say they work on contingency. Don't confuse those arrangements. While a free consultation covers the first discussion, contingency fees tie the attorney's payment to a recovery. Because expenses may be handled differently from attorney fees, ask about records and medical opinions, then check how the firm treats court fees.
How long will a misdiagnosis case take?
You won't find a single case length in the firms' published information. What steps would your claim need, and what might slow it down or otherwise affect its progress? Although Texas sets firm procedural clocks for filing and expert reports, those deadlines don't tell you when you might reach a settlement or get a verdict.
What deadline applies if my child was misdiagnosed?
If a child is under 12, the Texas rule allows filing until the fourteenth birthday. Regardless of age, the 2-year rule applies otherwise. Your child's claim shouldn't be assumed to wait until adulthood. After giving a Texas lawyer your child's birth date and treatment dates, have them explain which deadline applies to the claim you're considering.
What changes if a loved one died after a missed diagnosis?
Alongside its caps on non-economic damages in health care liability claims, Texas limits total damages in death cases with a separate inflation-indexed cap. On several listed firms' sites, you'll find wrongful-death work. Don't treat a past recovery as what your claim could recover. How the death-case rules and filing deadline apply to your family is something to discuss with a Texas lawyer.
What should I do before calling a lawyer about a missed diagnosis?
After writing down the symptoms you reported and your appointment dates, note when you finally received the diagnosis. Bring together whatever records and bills you have. Even without a complete chart, you can ask about the filing deadline. When you call, find out who would review those records, then ask whether the firm has handled a diagnostic delay like yours.
