Diagnosis is hard, and medicine does not promise certainty. Many conditions look like others at first, and a physician can act carefully and still not reach the right answer on the first visit. When families ask us about a missed diagnosis, the review usually comes down to three questions: were the signs there, would a careful provider have acted on them, and did the delay change what happened to the patient.
These cases tend to follow recognizable patterns. A breast, lung, or colon cancer is visible on imaging but not reported, or a suspicious result is reported and never followed up. Chest pain is labeled indigestion or anxiety and the patient is later found to have had a heart attack. Sudden weakness, slurred speech, or a severe headache is treated as a migraine when it was a stroke or a bleed. An infection progresses to sepsis after repeated visits for fever and worsening symptoms. A lab result showing a serious problem sits in the chart without anyone calling the patient. A referral to another physician is ordered but never scheduled.
The common thread is time. These claims usually turn on what was known, when it was known, and what difference earlier action would have made.
1. Get the right care now
Whatever happened before, focus first on current treatment. Ask your new physicians to explain the diagnosis, when the condition likely began, and how it is being treated. Their notes often describe the stage or severity at diagnosis, which matters later.
2. Build a timeline of every visit and symptom
Write down each appointment, urgent care visit, emergency room trip, call, and portal message from the first symptom forward. For each, note the date, the provider, what you reported, what tests were done, and what you were told. Use calendars, phone logs, pharmacy receipts, and insurance statements to fill in dates you do not remember.
3. Request records from every provider, not just the last one
A delayed diagnosis often involves several providers: a primary care office, an imaging center, a laboratory, an urgent care, and a hospital. Request the complete records from each. Physicians must provide records "in a timely manner," and release may not be conditioned on payment for services (§ 456.057(6), (17), Fla. Stat.). Licensed hospitals must furnish copies after discharge on written request "in a timely manner, without delays for legal review" (§ 395.3025(1)).

§ 456.057(6), Florida Statutes
4. Ask for the actual images and test results
For imaging, ask for the radiology reports and a disc or download of the images themselves. For lab work and pathology, ask for the full results, including reference ranges and any slides or tissue held by the laboratory. A later reviewer may need to look at the original study, not just the report.
5. Save portal messages and referral records
Take screenshots of patient portal messages, test result notices, and appointment requests, with dates showing. Keep referral letters, prior authorization denials, and scheduling messages. These often show where a result or referral stalled.
6. Note when you first learned something was missed
Florida's deadline can run from when an incident was discovered or should have been discovered. Write down the date and circumstances when you first learned, or had reason to suspect, that an earlier result or symptom was not acted on, and who told you.
Florida deadlines and the presuit process
A diagnosis claim is judged against the standard of care: "that level of care, skill, and treatment which, in light of all relevant surrounding circumstances, is recognized as acceptable and appropriate by reasonably prudent similar health care providers" (§ 766.102(1)). A missed diagnosis, by itself, does not establish a breach. Reviewers also look closely at whether earlier action would have changed the outcome.

§ 766.102(1), Florida Statutes
Under § 95.11(5)(c), a claim generally must be brought within 2 years from the incident or from when it was discovered or should have been discovered with due diligence, and no later than 4 years from the incident. That outer limit can extend up to 7 years where fraud, concealment, or intentional misrepresentation prevented discovery. For a child, the 4-year limit does not bar a claim brought on or before the child's eighth birthday. Because delayed diagnosis cases often span many visits over months or years, identifying the right dates is one of the first things we do.
Before filing suit, the claimant must obtain a verified written medical opinion from a qualified physician supporting the claim (§ 766.203(2)) and serve a notice of intent on each prospective defendant, starting a 90-day presuit period during which the limitations period is tolled (§ 766.106). An automatic 90-day extension is available by petition to the clerk (§ 766.104(2)). Where the defendant practices in a particular field, the reviewing physician generally must practice in the same field (§ 766.102(5)). The rule barring recovery by a plaintiff more than 50 percent at fault does not apply in medical negligence cases (§ 768.81(6)), and § 768.21(8) limits certain wrongful death damages for adult children and the parents of an adult child.

Your checklist
- Focus on current treatment and ask when the condition likely began.
- Write a timeline of every visit, call, and portal message since the first symptom.
- Request complete records from every office, lab, imaging center, and hospital.
- Ask for the actual images and full test results, not only reports.
- Screenshot portal messages and keep referral and scheduling records.
- Write down when you first learned something was missed.
- Speak with a lawyer well before 2 years from that date.
How we review these cases
Delayed diagnosis cases are built on timelines. We gather records from every provider, line up each visit, test, and result in order, and identify the points where a different decision might have changed the outcome. Where the facts support it, we arrange a review by a qualified physician who practices in the relevant field, and we explain what the review shows in plain terms. Meetings are by appointment only. Call 305-748-3789 to schedule a time to talk.
