No source here explains why one Ohio employer’s renewal moved. What law does settle is narrower: federal rule closes the list of things that may move an ACA-compliant small-group rate, Ohio has added no variation of its own, and Ohio’s code requires a carrier offering a plan to a small employer to disclose how it may change rates.
What Ohio adds to the federal rating rules, and what it does not
Two instruments decide how an Ohio small-group rate may be built. One is a federal rule that applies in every state. The other is whatever the state has chosen to layer on top of it — its own age curve, its own tobacco ratio, its own family tiers, its own composite premium method, its own wider definition of a small employer.
Ohio has chosen none of it. On the federal table that records those elections state by state, Ohio’s row is blank in every column, including the column that records whether a state has adopted a composite premium method of its own. The table publishes the rule for reading a blank cell in its own words: If a cell is blank or a state is not listed, the federal default applies.
That table carries a caption date of its own — it reads Updated December 10, 2021 — and the page is served under a later modification stamp. So the accurate sentence is what that table records under its caption, not that Ohio has no such rule today. It is still the only consolidated federal record of what a state has and has not elected, and on it Ohio has elected nothing.
The consequence for a renewal conversation is practical. There is no distinctly Ohio lever to go looking for. If something moved the rate, it moved it through a mechanism that would have worked the same way in any state operating on the federal default.
The list of things that can move the rate is closed, and it is closed federally
For coverage in the small group market, federal rule lets a premium rate vary on a short, named set of things and then shuts the door. The closing clause at 45 CFR 147.102(a)(2) provides that the rate must not vary by any other factor not described in the paragraph above it. That is the whole architecture: a permitted set, and an express refusal of everything outside it.
This is a federal floor that applies in Ohio rather than a rule Ohio wrote, and it is worth saying plainly because the distinction changes who you argue with. The enumeration itself — which factors are on that permitted list, and what each one means — is the subject of its own article; what belongs here is that the list is closed, and that a renewal increase has to have come through something on it. If you want the underlying structure of the product the rate is attached to, our group health coverage page sets it out.
The address that fixes your rating area, and what moves it
One of the permitted variables is geography, and geography is the single dimension Ohio sets for itself. Ohio’s rating areas are drawn on counties rather than on three-digit zip codes or metropolitan statistical areas.
How a group is placed on that map is federal, and it is narrower than it first looks. For the small group market, 45 CFR 147.102(a)(1)(ii)(B) places the group using the group policyholder’s principal business address
, which the same paragraph then defines as the principal business address registered with the state, with a fallback to the in-state business address where the greatest number of employees works. It is not where employees live. It is not each worksite. There is one narrow proviso for a network plan whose service area does not reach that address.
So an address change is a real event. A relocation, or a correction to the address actually registered with the state, can move the group from one Ohio rating area to another. What we will not tell you is that one Ohio area is cheaper than another, because no source behind this article publishes a figure that would support it. The honest statement is that area assignment exists, that it is determined by that one address, and that we publish no number showing by how much it matters.
Ohio’s own rating statute is still on the books, and it is not what governs your renewal
An Ohio employer who searches the Revised Code for rating rules will find them, and they will look authoritative. Ohio Revised Code 3924.04 describes a small-employer rating mechanism built around variation from a midpoint rate. It returns cleanly from the state’s own code site and reads like current law.
It has been effective since March 23, 2007, in a single version, and it was written before the federal small-group rating rule existed. We state both texts and their dates and leave them standing: Ohio’s section says what it says, and 45 CFR 147.102 is what governs the rating of ACA-compliant small-group coverage. We do not assert which instrument displaces which, and we do not reproduce the percentages inside the Ohio section, because quoting them accurately would still describe a mechanism that is not how a modern small-group rate is built.
The same caution applies to Ohio’s small employer health care alliance program under Ohio Revised Code Chapter 1731, which Ohio authorizes as a purchasing mechanism and whose rating machinery is written directly on top of that 2007 section.
What a survey average of Ohio premiums can tell you, and what it cannot
There is a state-level premium figure for Ohio, and it is worth knowing what it is before someone uses it on you. The federal Medical Expenditure Panel Survey — MEPS-IC — puts the average total annual single-coverage premium at $8,379 per enrolled employee in 2025, at Ohio private-sector establishments with fewer than 50 employees that offer health insurance.
Three qualifiers travel with that number and none of them is optional. The unit counted is an establishment, generally a single physical location, classified by the size of the firm that owns it, so a single site of a large multi-location company is not in that column and a small company’s one site is. The figure is the total premium — employer and employee money together — not the employer’s cost. And it is measured only at establishments that already offer coverage, which is a narrower population than all small Ohio employers.
It is also a level, not a change. It cannot tell you whether Ohio premiums rose, because one edition is a snapshot. Set against a renewal it is context and nothing more: a statistic about a survey population, never a quote, never a benchmark, and never a statement about what your group should be paying.
What Ohio’s code requires your carrier to disclose about rate changes
This is a request an employer is entitled to make. Ohio’s code puts a disclosure duty on the carrier at the moment coverage is offered:
Each carrier, in connection with the offering of a health benefit plan to a small employer, shall disclose to the employer, as part of its solicitation and sales materials, the following information: (1) The provisions of the plan concerning the carrier’s right to change premium rates and the factors that may affect changes in premium rates.
Ohio Revised Code 3924.033 goes on to require that the information be provided in a manner determined to be understandable by the average small employer, and sufficient to reasonably inform that employer about its rights and obligations under the plan. The section has been effective since March 22, 1999, so treat it as what Ohio’s code provides rather than as a description of any particular carrier’s current practice.
Used well, it changes the shape of the renewal conversation. Instead of asking why the number went up, you are asking the carrier to point at the plan provisions it already had a duty to disclose — the ones describing its right to change rates and what affects that change. That is a document request, not an argument. It is also the natural first step when you are shopping a renewal rather than simply accepting one.
What no source behind this article measures
Saying what we checked and did not use is part of the answer here, because the gaps are where bad explanations get invented.
No source we rely on measures why an individual employer’s renewal moved. None publishes an Ohio year-over-year change, in dollars, in percent, or in words. The survey workbook does contain rows labeled with a span of years, and they are not established as a trend, a change, or a comparison, so they are not read as one. It also publishes premiums by metropolitan area, which looks exactly like proof that Ohio geography changes what you pay — but those rows carry no firm-size breakdown at all, and one of their areas crosses into two other states while Ohio’s rating areas stop at the state line. They cannot answer a small-employer question and they are not used.
We also do not publish the remainder of the premium after the employee share. The survey measures the employee side and publishes no employer figure for Ohio at any firm size, so the employer’s portion is described in words and never counted. The state page for Ohio carries the rest of the state-level background.
What to do with a renewal that moved
The useful sequence is unglamorous. Ask the carrier for the rate-change provisions and factors its own materials are required to disclose. Confirm which address is actually registered as the group policyholder’s principal business address, because that one field places the group on Ohio’s county-drawn map. Check whether anything in the group’s composition changed in a way the permitted federal variables would pick up. And then, separately, decide whether to test the market.
None of that produces a number that explains the increase on its own. It produces something better: a renewal you can describe in terms of the mechanisms that are actually allowed to move it. If you want a second read on an Ohio renewal packet, send it over and we will work through it in those terms.
The bottom line
No source we can cite explains why one Ohio renewal moved. What can be established is that the list of things allowed to move an ACA-compliant small-group rate is closed federally, that Ohio has added no rating variation of its own beyond drawing its geography on counties, and that Ohio’s code requires the carrier to disclose in its own materials how it may change rates and what affects those changes. Ask for that disclosure before you argue about the number.
Frequently asked questions
Does Ohio law cap how much a small group renewal can increase?
Not for an ACA-compliant small-group plan. Ohio Revised Code 3924.04 does describe a small-employer rating mechanism measured against a midpoint rate, but that section has been effective since March 23, 2007 and was written before the federal small-group rating rule existed. The rule that governs an ACA-compliant renewal today is the federal one at 45 CFR 147.102, which closes the list of things a rate may vary on and says nothing about a cap on year-over-year movement.
Has Ohio adopted its own rating rules that would explain the increase?
On the federal table that records each state’s rating elections, Ohio’s row is blank in every column, including the column for a state-specific composite premium method. The table states its own reading rule: where a cell is blank, the federal default applies. That is what the table records as of its own caption date, and it is the reason there is no distinctly Ohio lever to look for.
Can moving our office change what we pay in Ohio?
It can change which rating area the group is rated in. Under 45 CFR 147.102(a)(1)(ii)(B) a small group is placed by the group policyholder’s principal business address, not by where employees live and not by each worksite, and Ohio draws its rating areas on counties. Whether a different area costs more or less is not something we publish a figure on, because no source we rely on publishes one.
Is there an Ohio average premium we can compare our renewal to?
There is a state survey average, and it is not a benchmark for your group. The federal Medical Expenditure Panel Survey publishes an average total single-coverage premium for Ohio establishments at firms with fewer than 50 employees that already offer coverage. It is a survey average across a population your business may not sit in, it is a level rather than a change, and it explains nothing about one employer’s renewal.
What is our carrier required to tell us about how it changes rates?
Ohio Revised Code 3924.033 requires a carrier, in connection with offering a health benefit plan to a small employer, to disclose as part of its solicitation and sales materials the plan provisions concerning the carrier’s right to change premium rates and the factors that may affect those changes. The section also requires that the information be given in a manner an average small employer can understand. That section has been effective since March 22, 1999, so read it as what Ohio’s code provides.
