Claims-made vs. occurrence: what the difference actually costs you

• Occurrence — Covers any incident that happens while the policy is in force, whenever the claim arrives. · No maturity ramp. No tail to buy on the way out. Higher annual premium.
• Claims-made — Covers a claim only if the policy is active both when the incident happened and when the claim is filed. · Ramps to maturity over four or five years. Leaves a tail obligation. Cheaper year to year.

Two malpractice policies can carry the same limits, cover the same physician, and price very differently, because they are built on different triggers. Claims-made and occurrence are the two forms almost every physician chooses between, and the choice shapes both your annual premium and a bill you may not see coming for years. Here is how each works, why the numbers look the way they do, and why our benchmark is stated on one of them.

Every rate figure here comes from carrier rate filings on record with state insurance departments (the SERFF system and state DOIs), on a $1M/$3M mature claims-made basis. These are filed rates, not estimates.

The two forms, plainly explained

An occurrence policy covers any incident that happens while the policy is in force, no matter when the claim is eventually filed. Treat a patient this year, get sued four years from now, and the policy you held this year responds, even if you have long since let it lapse.

A claims-made policy covers a claim only if the policy is active both when the incident happened and when the claim is filed. The coverage lives in the present: it protects you for past incidents only as long as you keep paying, or keep the reporting period alive. Let it lapse without arranging for the gap, and claims that arrive later have nothing behind them.

That single difference, when the coverage triggers, drives everything else: how the premium ramps, what happens when you leave, and why the two forms cost what they do.

How claims-made premiums ramp, and why "mature" matters

A claims-made premium is low in the first year and steps up each year until it levels off. The reason is exposure. In year one, the only claims that can be filed are for incidents from that one year. By year four or five, claims can arrive for any of the prior years the policy has covered, so the carrier is on the hook for far more, and the premium reflects it.

The step-up is written into the rate filings. A typical filed maturity schedule pays roughly 40% of the full rate in year one, then about 60%, then about 85%, reaching 100% by year four or five. Applied to the filed general-surgery median of about $48,438, that first-year rate is closer to $19,000, climbing to the full figure only once the policy matures.

Compare a year-one number to a mature number and you are not comparing the same thing.

This is why "mature" is the word that matters. The mature rate, the year-four-or-five level, is the true ongoing cost of the coverage. A first-year claims-made quote can look like a bargain next to a mature benchmark when it is simply early in its ramp.

Occurrence: simpler, usually costlier up front

Occurrence coverage skips the ramp. Because each year's policy already covers future claims from that year, there is no tail to buy when you leave and no maturity curve to climb. It is the simpler product, and for that reason it usually carries a higher annual premium than the equivalent mature claims-made rate. You are paying up front for protection that a claims-made physician defers, and partly pays for later through tail coverage.

That trade sits at the center of the decision. Claims-made is cheaper year to year, especially early, but carries a future obligation. Occurrence costs more annually and settles that obligation as you go.

Why the benchmark uses mature claims-made

Our benchmark states every rate at the $1M/$3M mature claims-made basis, and the reason is comparability. Claims-made is the form most physicians carry, so it is the common denominator. Mature is the one point on the ramp that means the same thing everywhere: the full, ongoing cost, stripped of where a given physician happens to sit in their first few years. Normalize to that and a rate in one state and specialty compares cleanly to any other. Leave rates on mixed years and maturities and the comparison falls apart. Carriers that file occurrence-only are converted to a claims-made-equivalent mature rate before they enter the benchmark, for the same reason.

So when you check your quote against the benchmark, confirm your quote is also a mature claims-made number.

• A first-year claims-made quote — It will sit below the benchmark for now and rise as the policy matures.
• An occurrence quote — Expect it to sit somewhat above the mature claims-made benchmark.

Which is right for you

There is no universal answer, because the forms suit different situations. A physician near retirement may prefer occurrence to avoid buying a tail at the end. An early-career physician joining a group often takes claims-made because the employer covers the tail, or because the low first-year rate matters while income is building. What you own when you leave differs too: claims-made leaves you needing tail coverage, typically priced around twice your mature annual premium and sometimes more, which is its own decision worth understanding before you sign.

This is where a broker earns their fee. One who works your specialty and state can lay the two forms side by side for your situation, price the tail obligation honestly, and show you which carriers write which form where you practice. The benchmark gives you the mature claims-made yardstick; a broker helps you decide which structure fits and shops it.

Common questions

Is claims-made or occurrence cheaper?

Claims-made is cheaper year to year, especially in the early years while the premium is still ramping to maturity. Occurrence usually costs more annually but has no tail to buy when you leave. The fair comparison is occurrence against a mature claims-made rate, not a first-year one.

What does "mature claims-made" mean?

The claims-made premium at the point it levels off, usually year four or five, when the policy covers claims from all prior years. It is the true ongoing cost of the coverage, which is why our benchmark uses it.

Do I need tail coverage with occurrence?

No. Occurrence already covers future claims from each year it was in force, so there is no gap to fill when you leave. Tail coverage is a claims-made concern.

Sources and method

• Source — Carrier rate filings on record with state insurance departments (SERFF and state DOIs)
• Basis — $1M/$3M limits, mature claims-made, manual (pre-credit) rate
• Figure used — The filed general-surgery national median of about $48,438, used to illustrate the maturity ramp
• Step schedule — The roughly 40 / 60 / 85 / 100 maturity steps are a typical filed schedule drawn from the filings behind the benchmark, shown as illustrative rather than one carrier's exact factors
• Tail pricing — About twice the mature annual premium is a common market range, treated in detail in the tail-coverage piece
