Misdiagnosis in Massachusetts
Average Settlement: $300,000 - $900,000 | Statute: 3 years from the date the cause of action accrues
About Misdiagnosis
Misdiagnosis occurs when a healthcare provider incorrectly identifies a patient's condition, leading to inappropriate treatment or no treatment at all. This is one of the most common forms of medical malpractice and can result in disease progression, unnecessary procedures, or harmful medications. Cancer misdiagnosis is particularly devastating, as delayed treatment can mean the difference between a curable and terminal prognosis.
Massachusetts Medical Malpractice Laws
Statute of Limitations
3 years from the date the cause of action accrues
Damage Cap
$500,000 non-economic damages (with exceptions: the cap does not apply if there is a substantial or permanent loss of bodily function, disfigurement, or other special circumstances)

Pre-Filing Requirements
Claims must be reviewed by a tribunal (judge, physician, attorney) that determines if the evidence is sufficient to raise a legitimate question of liability.
Common Examples of Misdiagnosis
- •Diagnosing a malignant tumor as benign
- •Misidentifying a heart attack as acid reflux or anxiety

Key Facts
- ✓Studies indicate that diagnostic errors affect approximately 12 million adults in the United States each year in outpatient settings
- ✓To prove misdiagnosis, the plaintiff must show that a competent physician in the same specialty would have correctly identified the condition under the same circumstances
- ✓Medical records documenting the patient's reported symptoms, test results, and the physician's reasoning are essential to building a misdiagnosis case
- ✓Misdiagnosis claims often require demonstrating that the correct diagnosis was on the physician's differential diagnosis list but was improperly ruled out
- ✓The damages in misdiagnosis cases are measured by the difference in outcome between what occurred and what would have happened with a timely, correct diagnosis
- ✓Radiology and pathology misreads are among the most clear-cut misdiagnosis cases because the evidence is preserved in images and slides
- ✓Massachusetts requires a medical malpractice tribunal hearing to assess whether the case has sufficient merit before it can proceed.
- ✓If the tribunal finds insufficient evidence, the plaintiff may still proceed by posting a bond (typically $6,000).
