A delayed diagnosis claim is not an argument about what the condition was. Everyone agrees on that by the time a family comes to us. The argument is about time: how much was lost, whether it should have been lost, and what difference it made.
That last question is where these claims are decided, and where Maryland is harder on patients than many states.
How the time actually gets lost
Delay is rarely one dramatic error. It is usually a handoff that did not happen:
- A result that came back abnormal and was never communicated to the patient or the treating doctor — the most common single failure we see.
- A referral made and never followed up, or an appointment that was never actually booked.
- "Come back if it gets worse" offered repeatedly instead of investigation, across three or four visits for the same complaint.
- A scan reported days or weeks after it was performed, or reported and not escalated.
- Routine screening not offered where the patient’s age, history or risk factors called for it.
- Symptoms attributed to an existing condition, so a new problem was folded into an old explanation.
- Care split between providers, where each assumed the other was following it up.
Where the conclusion reached was actively wrong rather than merely late, that is a misdiagnosis claim, and it is proven differently.
The loss-of-chance problem
Here is the distinction that decides delay cases, and it is worth understanding before you call anyone.
Some states allow a claim for a lost chance of a better outcome: if a delay reduced someone’s survival prospects from, say, 45% to 20%, those states let a patient recover for the chance that was taken away. Maryland does not follow that approach. Maryland requires proof that the delay more likely than not caused the harm — that with timely diagnosis the outcome probably would have been different.
The practical consequence is blunt: where a condition was already likely to end badly, a delay that made it worse may still not support a claim here, even though the delay was plainly negligent. Where timely diagnosis probably would have changed things — an earlier stage, a treatable infection, an operable condition — the claim is strong.
We would rather explain that at the first conversation than take a family through two years of litigation to reach it.
The conditions where time changes everything
- Cancer, where delay is measured against stage at diagnosis. A condition caught at an early stage and one caught late are different diseases in treatment terms, which is what makes staging evidence central.
- Sepsis, where the window is hours and the deterioration is documented in observations that were recorded and not acted on.
- Stroke, where the treatment window is short and rigidly defined, making the timeline unusually easy to reconstruct.
- Heart attack, particularly where an atypical presentation was sent home.
- [Cauda equina syndrome](/medical-malpractice-lawyer/cauda-equina-syndrome/), the clearest example there is of a condition where hours decide permanence.
- Infections, including post-surgical infections allowed to spread.
- Conditions in pregnancy and at birth, handled as birth injury claims.
These cases are built as a timeline
- Every contact, in order. Each visit, call and message where the symptom was raised, with dates — this is what turns "they kept dismissing me" into a documented pattern.
- What was ordered, when it was performed, and when it was reported. The gaps between those three are frequently where the claim lives.
- What the results showed, and who saw them.
- When the diagnosis was finally made, and what the condition looked like by then.
- What it would have looked like at the earlier point — the stage, the spread, the treatability. This is the expert question and the one that decides value.
- What that difference means for treatment, prognosis and life expectancy.
Maryland requires a certificate from a qualifying expert before the claim proceeds, and it is filed with the state health care dispute office first, like any medical malpractice claim.
Deadlines, and the discovery question
Maryland malpractice claims generally run five years from the injury or three years from when the injury was discovered, whichever comes first, with different rules for children.
Delay cases are the ones where those two dates most often diverge, because patients usually learn that a delay occurred long after the visits that caused it — frequently only when a new doctor looks back through the file and says something should have been caught earlier. If that has just happened to you, ask now rather than assuming the time has gone.
