The letter that arrived three years too late

Picture a family physician, hypothetical but common, who spent four years with a group in Plano and then opened her own practice in a new medical suite in Frisco. Her new claims-made policy started on day one of the new practice. The premium was surprisingly low, the paperwork was quick, and her old group’s policy simply ended when she left.

Eighteen months later, a demand letter arrives about a patient she treated at the old group. She calls her new carrier, and the answer is short: the care happened before her retroactive date. She calls the old group, and the answer is just as short: nobody bought a tail. The care was real, the claim is real, and no policy is answering for it.

That gap is what a retroactive date is about. It isn’t a technicality. It’s the line that decides whether your past work is still protected. Proverbs 22:3 (KJV) puts it this way: “A prudent man foreseeth the evil, and hideth himself; but the simple pass on, and are punished.” Looking ahead here simply means knowing your date before you change anything.

This guide is written for physicians in Frisco, Plano, McKinney, and Dallas, and for anyone in Texas building a medical practice insurance program. It covers what the retroactive date does, how it gets lost, and how to protect it. As the Texas Department of Insurance’s medical liability shopping guide explains, a claims-made policy covers claims reported during the policy term only if the event occurred after the effective date of the first policy issued, unless a retroactive date extends coverage further back.

What a retroactive date actually is

A retroactive date is the earliest date of care, or the earliest act, that a claims-made policy will cover. The industry reference IRMI defines it as a provision in many, but not all, claims-made policies that removes coverage for claims arising from acts before a specified date, even if the claim is first made during the policy period.

From first principles, a claims-made malpractice policy generally asks two questions before it responds:

• When was the claim reported? It must be reported during the policy period, or during an extended reporting period (tail) if you purchased one.
• When did the care happen? It must have happened on or after the retroactive date shown on your policy.

Both answers have to fit. If you’re still unclear on how claims-made differs from occurrence, our guide to claims-made vs. occurrence malpractice coverage and tail coverage in Texas walks through both forms. Occurrence policies, which include most practice general liability policies, work differently. Our article on malpractice vs. general liability for Texas practices covers that split.

An everyday comparison helps. Your retroactive date works like the date a security camera started recording. If you swap cameras and the new one starts recording today, everything before today is gone unless you carry the old footage over. Prior acts coverage is how you carry it over. When a new carrier honors your original retroactive date, your history goes with you.

Most physicians find their retroactive date on the declarations page or on an endorsement attached to the policy. If you can’t find it, ask your agent or carrier to confirm it in writing. Don’t guess.

Why the retroactive date carries extra weight in Texas

Texas gives patients a defined but long window. Under Texas Civil Practice and Remedies Code §74.251, a health care liability claim generally must be filed within two years of the breach or the completion of treatment. A claim may not be brought more than 10 years after the act or omission (the statute of repose), and a minor under 12 has until the 14th birthday to file. Texas courts have limited how some of these rules apply in certain situations, so the exact deadline in any specific case is a legal question for an attorney.

For your insurance, the point is simple. Care you deliver this year can become a claim years from now, after you’ve changed carriers, joined a hospital system, or opened your own practice. Whichever policy is in force when the claim arrives has to reach back far enough to cover it, and the retroactive date sets how far back it reaches.

North Texas moves fast. Physicians here change jobs, join and leave groups, sell practices, and open new locations in Frisco, Prosper, and McKinney at a steady clip. Every one of those moves can disrupt your coverage. Our article on when Texas physicians actually need malpractice insurance lists the trigger events. Each one is also a moment to check your retroactive date.

Moonlighting and locum work add more layers. A shift covered under a facility’s policy or a locum tenens malpractice arrangement may carry its own retroactive date and its own reporting rules, separate from your main policy.

Five myths that cost physicians their retroactive date

• Myth: “My new policy covers anything reported while it’s active.” Reality: a claims-made policy generally covers only care on or after its retroactive date. If your new policy starts with a fresh retroactive date, a shift known as retroactive date advancement, earlier care usually falls outside it.
• Myth: “A newer retroactive date is a better deal because the premium is lower.” Reality: claims-made premiums are commonly step-rated. They start lower and rise as the policy matures, because there’s less prior exposure to cover. A lower premium with a fresh retroactive date often means less coverage, not a better price. Our breakdown of why Texas physician malpractice premiums rose in 2026 explains how that maturity step-up works.
• Myth: “My employer handles all of this.” Reality: an employer’s policy may cover you while you’re employed, but who pays for the tail when you leave depends on your employment contract and the policy. Read both before you sign and before you resign.
• Myth: “I’ll sort out the old stuff after I switch.” Reality: once a claims-made policy ends without a tail, and the new policy starts without prior acts coverage, the gap may not be fixable after the fact. New policies also commonly exclude incidents you already knew about before the policy began, through a prior knowledge exclusion. Report known incidents to your current carrier, as your policy requires, before it ends.
• Myth: “Retroactive dates are only a malpractice issue.” Reality: many cyber, directors and officers, and employment practices policies are also written on a claims-made basis, and many carry their own retroactive or prior-acts dates. D&O and EPLI forms may also carry a prior and pending litigation date. Check every claims-made policy your practice carries, including cyber insurance for medical and dental practices, EPLI for Texas medical practices, and medical directors and officers liability.

The numbers: how retroactive dates play out in real scenarios

The scenarios below are educational illustrations. Whether a specific claim is covered depends on your actual policy wording, endorsements, and the facts of the claim.

Why physicians should verify the retroactive date on every quote

A malpractice quote, whether it comes from an online application in minutes or from a full underwriting submission, is a price for a specific set of terms. Premium is the number everyone compares first. The retroactive date is one of the terms behind that number, and it decides how much of your past work the price actually includes. Two quotes with similar premiums can protect very different spans of your career.

That’s why the retroactive date deserves the same scrutiny as the premium. Before you bind any claims-made policy, verify these points in writing:

• The retroactive date on the quote itself. Confirm it matches your existing retroactive date, or the date you requested, and not just the new policy’s start date.
• Prior acts (nose) coverage. Is it included, and back to what date?
• The handoff. Make sure your current policy doesn’t end before the new policy, with any prior acts coverage, takes effect.
• The tail alternative. Get the cost of a tail from your current carrier so you can compare it against nose coverage.
• Individual vs. entity coverage. If your practice entity carries its own coverage, confirm its retroactive date separately.
• Known incidents. Report any incident you’re aware of to your current carrier as your policy requires before you switch, because new policies commonly exclude known matters.
• Your other claims-made policies. Cyber, D&O, and EPLI may carry their own retroactive dates.

The Agent’s Office® is an independent agency licensed in Texas and based at Frisco Station. Because we work with multiple carriers, we review these points across markets. We confirm your current retroactive date from your declarations page, ask each carrier about prior acts coverage, compare it against your tail cost, and check the retroactive dates on your practice’s other claims-made policies. Whether a carrier offers prior acts coverage depends on its underwriting, your claims history, and your specialty, so no agent can promise it in advance.
