What Can an Insurer Use to Rate Your Group in Indiana
Indiana’s small employer chapter does not print a list of what an insurer may charge your group for. It is written the other way round: claim experience, health status and duration of coverage are named as things a rate may not turn on, and everything else is left to the phrase “legitimate rating factors.” The closed list is federal.
The statute names what is excluded, not what is allowed
Two sections do the work, and neither is a list of permitted factors.
The first is a definition. IC 27-8-15-6 defines “case characteristics” as demographic or other relevant characteristics of a small employer, as determined by a small employer insurer, that are considered by the insurer in the determination of premium rates — and then states that claim experience, health status, and duration of coverage since issue are not case characteristics. Note what that does and does not do. It removes three things from a defined term. On its own it is not a prohibition at all.
The second is the section that gives this whole area its shape. IC 27-8-15-17(a) says the chapter “is not intended to affect the use by a small employer insurer of legitimate rating factors other than claim experience, health status, or duration of coverage in the determination of premium rates.”
Read that sentence slowly. It does not enumerate. It carves three things out of an open set and leaves the set itself undescribed. That is why an Indiana employer who goes looking for a published state list of permitted factors will not find one, and why the useful question is not “what may they use” but “what may they not.”
The rule that forbids everything it did not just name
The closed list exists, and it is federal. 45 CFR 147.102(a)(1) provides that a rate in the individual or small group market may vary only by determining the factors it then names, and paragraph (a)(2) closes the door behind it: “The rate must not vary with respect to the particular plan or coverage involved by any other factor not described in paragraph (a)(1) of this section.”
That sentence is the most load-bearing one on this page, and its grammar is worth noticing. It is not written as a list of prohibited items, which could always be argued to have missed something. It is written as a prohibition on everything outside one short list. Anything not named is out, by default, without needing to be mentioned.
This is a rule for a class — every state’s individual and small group market — and it does not name Indiana anywhere. It is the federal floor that applies in Indiana, which is a different statement from calling it Indiana’s rule, and the difference matters when someone tells you that your state does or does not allow something.
The four the federal rule does name, and one thing this page will not print
The factors the rule names are these: whether the plan or coverage covers an individual or a family; rating area; age; and tobacco use. That is the list. Your industry is not on it. The size of your group is not on it. How long you have held coverage is not on it. Whether one of your employees had a catastrophic year is not on it.
Two of those four carry numeric limits inside the regulation — the rule caps how far a rate may vary by age, and it caps tobacco variation as well. We are not printing either figure. A ratio pulled out of a regulation and dropped onto a page stops being a limit on an insurer and starts reading as a prediction about your quote, which is the opposite of what it is. If you want to see them, the regulation is linked above and it is plain text.
Rating area is worth one further note, because employers reach for the wrong address. The federal rule sets rating area in the small group market from the group policyholder’s principal business address, not from where each employee lives, and CMS records Indiana’s rating areas as drawn on county lines. The Indiana page carries more of that state-level picture.
Applying a factor to one employer and not to a comparable one
There is a second Indiana prohibition, and it is about evenness rather than about the list. IC 27-8-15-17(b) requires a small employer insurer to apply rating factors, including case characteristics, consistently with respect to all small employers in a plan with substantially the same benefit design characteristics.
That is a genuinely separate duty. The first question is whether a factor may be used at all. This one asks whether the factor was used the same way on the business down the road as it was used on you. An employer will almost never be able to test it from the outside — you do not see the other business’s file — but it is a real obligation sitting in the statute, and knowing it exists changes the questions you can reasonably ask when a quote arrives with something in it you do not recognize.
Real-World Scenario: A Greenwood employer received a quote with a number he could not account for and went looking for the Indiana rule that would explain it. He expected to find a list of what an insurer is allowed to consider. What he found instead was a sentence saying the chapter does not affect legitimate rating factors other than three named ones — a carve-out where he had expected an inventory. The rule he needed was not missing. It was written as a prohibition, and it was mostly federal.
The prohibition attached to the headcount method
Here is the one almost nobody expects. The rule against using claim experience and health status does not stop at the rate — it reaches the counting.
IC 27-8-15-14(c) requires a small employer insurer to use either the definition under subsection (b)(1) or (b)(2), and to apply that definition “in a consistent manner without regard to the claims experience, health status, duration of coverage, or case characteristics of the employees of a small employer.” In other words, the insurer may not select which headcount method to apply to your business based on what it knows about your employees’ claims or health.
That subsection carries the chapter’s most recent amendment, P.L.236-2025. It is not old text. Whatever you conclude about the rest of the chapter, this part of it is live.
A 1992 sentence that points the other way
Now the passage that an Indiana employer will eventually find, and the reason this page exists in the shape it does.
IC 27-8-15-16 itemizes what a renewal increase may be composed of, and one of the items is an adjustment — limited by the section — “due to the claim experience, health status, or duration of coverage of the employees or dependents of the small employer.” Claim experience. Health status. The two things the rest of the chapter takes such care to exclude.
The section was added by P.L.127-1992 and carries no amendment since. The federal rule closing small group rating to the four named factors came afterward, and claim experience and health status are not on that list.
We are going to do something unusual here and simply stop. Both texts exist, both are quoted above with their dates, and we are not going to tell you which one controls, because that is a legal conclusion and this is an insurance agency rather than a law firm. What we will say is what follows practically: if a rate or a renewal arrives with your group’s claims or your employees’ health attached to it as an explanation, that is a question to put to the carrier in writing, and the federal rule linked above is the text to have open while you ask it.
The only reasons the statute gives for ending a plan
Rating is one half of what a small employer worries about. The other half is whether the plan survives a bad year. Indiana writes that as a closed list too: IC 27-8-15-19 provides that a small employer insurer may only cancel or refuse to renew a health insurance plan for the reasons it goes on to name — nonpayment of required premiums, fraud or misrepresentation, failure to comply with a material plan provision relating to employer contribution or group participation rules, the absence of any insured individual who lives, resides or works in the service area, the end of the employer’s membership in the association through which the plan was written, and market withdrawal.
Health status is not among them. The section does open with an exception pointing at a neighboring section, which we have not read in full and will not characterize. Read as it stands, the list is closed and it is about premium, honesty, the plan’s own participation and contribution rules, geography, membership and withdrawal.
A separate chapter on genetic screening
One more prohibition sits outside the small employer chapter entirely. IC 27-8-26-5 addresses the use of genetic screening or testing, and the chapter states that it reaches group policies, health maintenance organization contracts, governmental self-insurance, and — unusually — self-funded employee welfare benefit plans.
That last category is why we are naming the chapter rather than summarizing it. Whether a state provision written that way actually binds a self-funded plan governed by federal benefit-plan law is a question we have not verified, and it is not one to settle with a confident sentence on a web page. What we will report is what the chapter says it applies to. If your plan is self-funded, or if somebody is proposing that it become self-funded, that is a conversation for counsel and it is worth having before the plan design is chosen.
Asking the carrier which factors produced your number
All of the above turns into two or three sentences you can actually send. Which of the permitted factors moved between the last quote and this one. Whether the factors applied to your business are the ones applied to every employer in a plan with substantially the same benefit design. And, if claims or health were mentioned to you at any point in the conversation, a written explanation of what that referred to.
Nobody is obliged to enjoy those questions, and asking them is not an accusation. It is what having the law open in front of you looks like. If you would like someone to ask alongside you, that is part of what we do when we take on a renewal — see shopping a renewal, or first-time group health if you are not yet in a plan at all. The mechanics of the coverage itself sit on the group health page, and the other lines you might carry alongside it — group vision and group disability — have their own. We are licensed in nine states, listed on our states page. To put a group in front of the market, ask for pricing; to talk through a quote you already have, get in touch or read more about us.
The bottom line
Indiana names what a small group rate may not turn on, and the closed list of what it may turn on is federal — which makes this an area of law best read as a set of prohibitions.
Frequently asked questions
Is the Indiana rating chapter the current rule for a new small-group plan?
Parts of it are plainly current and part of it raises a real question. IC 27-8-15-14(c) carries a 2025 amendment. IC 27-8-15-16, the renewal section, was added in 1992 and has never been amended, and the federal rule at 45 CFR 147.102 closes the permitted rating factors to a list that section predates. We state both texts and their dates; we do not tell you which one controls.
What does the statute mean by case characteristics?
IC 27-8-15-6 defines case characteristics as demographic or other relevant characteristics of a small employer that the insurer considers in setting premium rates, and then removes three things from that term: claim experience, health status, and duration of coverage since issue. That is a definition rather than a prohibition on its own. The prohibition is built from reading it alongside IC 27-8-15-17 and the federal rule.
Where does age come into the rate?
Age is one of the factors 45 CFR 147.102(a)(1) permits a small group rate to vary on, and the rule limits how far a rate may vary by age. We do not print that limit here, because a ratio lifted out of a regulation and set loose on a page tends to be read as a promise about your quote. Ask the carrier how age enters your rate.
Can two employers with the same plan design be rated on different factors?
IC 27-8-15-17(b) requires a small employer insurer to apply rating factors, including case characteristics, consistently with respect to all small employers in a plan with substantially the same benefit design characteristics. It is a separate duty from the list of what may be used at all, and it is the one that says a factor cannot be applied to you and quietly not applied to a comparable business.
The genetic screening chapter names self-funded plans. Does it bind ours?
IC 27-8-26-5 prohibits genetic screening or testing being used in the way that chapter describes, and the chapter states that it reaches group policies, health maintenance organization contracts, governmental self-insurance and self-funded employee welfare benefit plans. What we have not verified is how that reaches a self-funded plan governed by federal benefit-plan law. If your plan is self-funded, that question belongs with counsel.
