Dallas Misdiagnosis Malpractice Attorneys
Diagnostic errors can turn treatable conditions into life-threatening emergencies. If a Dallas provider missed, delayed, or misread the signs, a misdiagnosis lawyer at McMahon Dean can investigate and fight for the compensation you need to move forward.
When Does a Misdiagnosis Become Malpractice?
Not every missed diagnosis is malpractice. We must show that a competent doctor in similar circumstances would have identified the condition or
ordered appropriate tests-and that the delay or error caused harm. Example: classic cancer symptoms dismissed as a minor infection, costing months of critical treatment time.

Commonly Misdiagnosed Conditions
Cancer (including lung, breast, colorectal), heart attack (mistaken for indigestion), stroke (missed in triage), sepsis and meningitis (treated as minor illness), and fractures or ligament tears (overlooked on imaging). These errors occur in ERs, urgent care centers, and primary care offices across Dallas.
Delayed Diagnosis vs. Failure to Diagnose
A delayed diagnosis means the correct condition was eventually found-but too late to prevent additional harm. Failure to diagnose means it was never correctly identified. Both can be actionable if the delay or failure
worsened the outcome.
How We Prove a Diagnostic Error
McMahon Dean secures medical records, imaging, and lab data; interviews witnesses; and works with independent specialists to establish what should have happened-what test, referral, or differential diagnosis was required-and how the lapse caused injury. We also manage Texas's
expert-report requirement to keep your case on track.
Impact of Misdiagnosis
Late-stage cancers may require harsher treatments; missed heart attacks can leave permanent cardiac damage; untreated infections can lead to sepsis. The financial and emotional costs mount quickly-additional care, lost earnings, and reduced quality of life.
Misdiagnosis FAQs
The doctor found it later-do I still have a case?
Possibly. If an earlier diagnosis would likely have improved your outcome, we'll develop that proof with experts
Can I sue for a loved one's death due to misdiagnosis?
Yes-families may bring a wrongful death malpractice claim.
What compensation is available?
Medical costs, lost income, and non-economic damages (subject to Texas caps in med-mal cases).
Are misdiagnosis cases harder to win?
They can be. Defense often claims the disease was too aggressive anyway. We counter with credible medical testimony.
How long do I have to file?
Texas generally allows two years, with specific rules for discovery and minors. Act quickly.
