Professional Liability (E&O) and Malpractice Insurance Claim Denied: Wrongful Acts, Retroactive Dates, and Reporting Requirements

Professional liability insurance — also called errors and omissions (E&O) insurance or malpractice insurance — protects professionals from claims arising out of their professional services. Doctors, attorneys, accountants, architects, engineers, consultants, technology service providers, and countless other professionals rely on these policies. When a claim is made and the carrier denies coverage, understanding the specific mechanics of professional liability policies is essential to fighting back.

How Professional Liability Policies Work

Unlike CGL policies, almost all professional liability policies are claims-made policies. This means two things:

1. The claim must be made during the policy period (or an extended reporting period)
2. The wrongful act must have occurred after the retroactive date specified in the policy

Both requirements must be satisfied. This structure is fundamentally different from occurrence-based CGL policies and creates specific pitfalls that lead to many coverage denials.

The "Wrongful Act" Requirement

Professional liability policies cover claims arising from a "wrongful act" — typically defined as a negligent act, error, or omission in the performance of professional services. This definition has specific components that carriers dispute:

Negligent act, error, or omission. The threshold question is whether the claimed conduct falls within the policy definition. If the client is alleging intentional fraud, intentional misconduct, or conduct unrelated to professional services, the carrier may argue the wrongful act definition is not met.

In the performance of professional services. The policy specifies what "professional services" means — usually the specific profession listed in the Declarations. Services rendered outside that scope, side businesses, or advice given informally may fall outside coverage.

As defined in the policy. Some E&O policies define wrongful act more narrowly for specific professions. Technology E&O policies, for example, may define the covered professional services as specific listed activities. Read the definition carefully — if the alleged conduct does not match, the carrier will deny coverage.

Retroactive Date Disputes

The retroactive date is the earliest date from which covered wrongful acts can arise. A wrongful act that predates the retroactive date is not covered, even if the claim is made during the policy period.

Retroactive dates become a coverage issue when:

• You switched carriers and the new carrier assigned a retroactive date that is more recent than your prior policy's inception
• Your policy lapsed and was renewed with a new retroactive date
• You purchase a new policy without "prior acts" coverage from your previous carrier

Common retroactive date problems arise in physician group practices when coverage arrangements change, in law firm lateral hiring situations, and in business acquisitions where the acquired company's prior professional conduct is not covered by the acquirer's policy.

If the carrier is denying coverage because the wrongful act predates the retroactive date, examine:

• Whether the retroactive date in your current policy was correctly set to provide continuous coverage
• Whether a prior acts tail endorsement should have been purchased
• Whether there was broker error in placing the coverage

Claims-Made Timing and the Reporting Requirement

Professional liability coverage is triggered when a claim is "made" — meaning the first communication to the insured that a professional error has caused harm or that a lawsuit is threatened. The definition of "claim" in your policy matters.

Key timing rules:

• The claim must be reported to the carrier during the policy period or within the extended reporting period (ERP/tail coverage)
• Many policies require reporting of "circumstances that might give rise to a claim" even before a formal claim is made — early notice of potential problems triggers the policy

Carriers frequently deny coverage based on:

Late reporting. If you received notice of a professional error or lawsuit threat during one policy period but did not report it to the carrier until the next period, the claim may fall between the cracks — not reported under the old policy, not a "claim made" under the new one.

Prior knowledge exclusion. Most E&O policies exclude claims arising from wrongful acts the insured knew about before the policy period. If you were aware of the potential claim before the policy incepted, coverage may be denied. Disputes arise over what "knowledge" requires — was awareness of a client's dissatisfaction enough to constitute prior knowledge?

Failure to report circumstances. If you knew of circumstances that might give rise to a claim and failed to report them during the policy period, some policies allow the carrier to deny coverage when the claim materializes in a later policy period.

Intentional Act and Criminal Act Exclusions

Professional liability policies exclude coverage for:

• Intentional fraud or dishonest acts
• Criminal acts or violations of criminal law
• Gaining personal profit or advantage to which you were not entitled

These exclusions are commonly invoked when a client claims intentional misconduct or fraud. The key question is whether the conduct was truly intentional or whether it was negligence characterized as intentional in the plaintiff's complaint.

In most states, the duty to defend based on the pleadings means the carrier must defend even if the complaint alleges intentional acts, as long as the underlying facts could support a covered negligence theory. If the carrier is refusing a defense based on the intentional act exclusion alone, that may be premature.

Challenging a Professional Liability Denial

1. Obtain the complete denial letter and identify the specific policy provisions cited
2. Compare the policy definitions (wrongful act, professional services, claim) to the facts of the underlying matter
3. Research the retroactive date history and any prior acts issues
4. Examine the timing of when you became aware of the claim or circumstances and when you reported
5. If the denial involves an intentional act exclusion, analyze whether the underlying complaint states a potentially covered negligence theory
6. Consult with coverage counsel — professional liability denials often involve subtle policy interpretation questions

Fight Back With ClaimBack

E&O and professional liability denials often hinge on complex policy language and timing issues. ClaimBack helps professionals organize the relevant documentation, trace the claims-made timeline, and build a compelling appeal to the carrier or through the formal dispute process.
