Medical Malpractice Insurance and Understanding Defendants

Part of the Medical Malpractice investigation

The short answer

Medical malpractice insurance is the practical mechanism through which malpractice claims are resolved. Understanding policy types (claims-made vs. occurrence), typical coverage limits, and which defendants carry what insurance is essential for evaluating the realistic recovery potential of a malpractice case.

Policy limits directly influence settlement strategy.

Claims-Made vs. Occurrence Policies

Most physician malpractice insurance is written on a claims-made basis — coverage applies only if the policy was in force both when the negligent act occurred and when the claim is made. If a physician lets their claims-made policy lapse, they have no coverage for prior acts unless they purchase 'tail coverage' (an extended reporting period endorsement). Occurrence policies — less common and more expensive — cover any act that occurred during the policy period regardless of when the claim is filed. Understanding which type of policy the defendant carries determines whether coverage exists for historical claims.

Typical Coverage Limits

Individual physicians typically carry malpractice coverage of $1M per claim / $3M annual aggregate, though coverage amounts vary significantly by specialty and state. Neurosurgeons, obstetricians, and cardiovascular surgeons — the highest-risk specialties — often carry $2M-$5M per claim. Hospitals carry significantly larger policies — $10M to $50M or more per occurrence — making them critical defendants in high-value cases. In states without damage caps, cases where damages clearly exceed policy limits create opportunities for excess verdicts and bad faith claims against the insurer for failing to settle within policy limits. In those situations, the insurer — not the physician — can bear the risk of an over-policy verdict.

Who Are the Potential Defendants?

A thorough malpractice case identifies all potentially liable defendants: the treating physician(s); the hospital or healthcare system; nursing staff (through the hospital's vicarious liability); subspecialists who were consulted or who rendered specific care; anesthesiologists or CRNAs; radiologists who misread imaging; pathologists who misread specimens; and, in medication error cases, the dispensing pharmacy. Each defendant carries their own insurance policy, and each policy provides a potential source of recovery. In complex cases involving multiple providers across multiple visits, all defendants are named in the complaint, with liability apportioned by the jury.

Frequently Asked Questions

12 QUESTIONS

Medical malpractice occurs when a healthcare provider — physician, surgeon, nurse, hospital, or other licensed provider — deviates from the accepted standard of care and that deviation causes preventable harm to a patient. The standard of care is defined as what a reasonably competent provider in the same specialty would have done under the same or similar circumstances. Malpractice is not simply a bad outcome — medicine involves inherent risks, and a patient can suffer a serious complication even with perfectly delivered care. To be malpractice, the provider must have acted negligently: doing something a competent provider would not have done, or failing to do something a competent provider would have done.
