What Can an Insurer Use to Rate Your Group in Texas

In Texas an insurer builds a small group rate from a closed list. Tex. Ins. Code Ch. 1501, Subch. E confines it to a class of business, an index rate and a statutory list of case characteristics, and the federal rating rule narrows that list further. Health status cannot move one enrollee’s rate, and tobacco is a group-level adjustment.

The longer answer is worth having, because the Texas structure and the federal one sit on top of each other and do not agree on their face.

One pool first: Texas starts by forbidding separate classes

The Subchapter E heading reads “UNDERWRITING AND RATING OF SMALL EMPLOYER HEALTH BENEFIT PLANS”, and its first move is a prohibition. Tex. Ins. Code § 1501.202(a) says that except as otherwise provided by the subchapter, a small employer health benefit plan issuer may not establish a separate class or classes of business for small employers. Separate classes are permitted only to reflect substantial differences in expected claims experience or administrative costs arising from enumerated reasons in Tex. Ins. Code § 1501.202(b), and additional classes beyond the statutory ceiling require application to and approval by the commissioner under Tex. Ins. Code § 1501.202(e).

Some grounds are closed outright. Tex. Ins. Code § 1501.203(a) bars a class based on “(1) participation requirements; or (2) whether the coverage provided to a small employer group is provided on a guaranteed issue basis or is subject to underwriting or proof of insurability.” Tex. Ins. Code § 1501.203(b) bars using, directly or indirectly, “the number of employees and dependents of a small employer” or “the trade or occupation of the employees … or the industry or type of business of the small employer”, with one cross-referenced exception.

A class of business is the pool your rate is measured against, and Texas makes it hard to subdivide on purpose.

The index rate is the anchor

Once the class exists, the index rate is what everything else is measured from:

“‘Index rate’ means, for each class of business and for a specific rating period for small employers with similar case characteristics, the arithmetic average of the applicable base premium rate and corresponding highest premium rate.”

— Tex. Ins. Code § 1501.201(4)

Tex. Ins. Code § 1501.204 then caps how far one class’s index rate may sit from another’s, and how far a particular employer’s rate may sit from its own class’s index rate. Both distances are bounded by statute rather than by an issuer’s judgment.

Two more rules close the structure. Tex. Ins. Code § 1501.210(a) requires an issuer to apply rating factors, including case characteristics, consistently with respect to all small employers in a class of business, so that rates for otherwise identical groups “differ only by the amounts attributable to health benefit plan design.” And Tex. Ins. Code § 1501.210(e) says an issuer “may not transfer a small employer involuntarily into or out of a class of business.” You cannot be moved into a worse pool without agreeing to it.

The case characteristics an issuer may use without asking the commissioner

This is the list the question is usually really about:

“Without the prior approval of the commissioner, a small employer health benefit plan issuer may not use case characteristics other than: (1) the geographic area in which the small employer’s employees reside; (2) the age and gender of the individual employees and their dependents; (3) the number of employees and dependents; and (4) the appropriate industry classification.”

— Tex. Ins. Code § 1501.210(c)

And the statute subtracts as well as adds. Tex. Ins. Code § 1501.201(2) removes from the term case characteristics three things by definition: “(A) health status related factors; (B) duration of coverage since the date of issuance of a health benefit plan; or (C) whether a covered individual is or may become pregnant.”

Note the seam between this section and Tex. Ins. Code § 1501.203(b): industry classification is a permitted rating characteristic while industry is a forbidden ground for a separate class. Those are different jobs in one statute, and reading only one of them produces the wrong conclusion about the other.

The federal list underneath the Texas list

Any ACA-compliant small group plan also sits under a federal rating rule, and that rule is shorter and harder. The enumeration at 45 CFR 147.102(a)(1) lets a rate vary only by whether the coverage covers an individual or family, by rating area, by age, and by tobacco use — each with its own conditions attached in the regulation’s own text. The paragraph that follows closes the list: “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” (45 CFR 147.102(a)(2)).

Gender is not in that enumeration. Group size is not in it. Industry is not in it. Claims experience is not in it. That is the gap between the two structures, and the rest of this post is about where the gap shows up.

Tobacco in Texas is a group-level adjustment, not a per-person load

This is the sharpest Texas-specific fact on the whole subject, and the regulator states it in its own voice:

“No. Federal law 42 USC §300gg and 45 CFR §147.102 permit nongrandfathered small group premiums to vary by up to 1.5:1 due to tobacco use, but federal regulations clarify that these provisions do not preempt more narrow state law requirements. In Texas, TIC §1501.206 prohibits adjustment of individual small group enrollee premium rates based on the health status of the individual enrollee. In Texas, tobacco use has historically been considered a health status element, as evidenced by the definition of ‘health status related factor’ in TIC §1501.002(7), which includes medical history and evidence of insurability. Texas will not change this interpretation. Carriers may reflect the tobacco surcharge in the rate charged to a small employer; however, the surcharge must be applied uniformly to the rates charged for all members of the small employer.”

A rating factor that national writing on this subject routinely describes as available is, in Texas, unavailable at the individual enrollee level. The consequence is concrete and worth checking on any proposal: a Texas tobacco surcharge rides on the employer’s rate uniformly rather than attaching to the people who use tobacco. If you are reviewing group health coverage for a workforce where that matters, it is a question with a definite Texas answer.

Two authorities, two geographies — and why a Texas city name settles nothing

Geography moves a rate under both structures, and they do not describe the same geography.

The federal rule ties the small group rating area to the group policyholder’s principal business address, with a network-plan fallback, at 45 CFR 147.102(a)(1)(ii)(B). The Texas statute’s case-characteristic list speaks instead of “the geographic area in which the small employer’s employees reside” at Tex. Ins. Code § 1501.210(c)(1). Those are different tests, from different authorities, doing different jobs, and they should not be collapsed into one sentence about “where you are.”

Underneath both sits a fact about how Texas rating areas are drawn. CMS publishes Texas’s rating-area table, Texas Geographic Rating Areas, and it draws them on counties. Houston’s city limits lie in Harris, Fort Bend and Montgomery counties, and CMS places those counties in different rating areas; Dallas’s limits reach counties CMS splits between areas as well, while Fort Worth spreads across county lines without crossing a rating-area line. So the words “Houston, TX” do not settle a rating area the way a buyer expects — the county does, and a Texas city can sit in more than one. If your census spans a metro, that is worth checking before you compare anything, and it is the kind of detail we work through on our Texas page.

Per member first, composite second

Texas premiums are built individually before they are presented collectively. The Texas Department of Insurance, quoting the federal approval of the state’s method, states that “Small group issuers must first rate all the individuals in a group on a per-member basis following the Market Reform Premium Rules”, and that issuers in Texas need to use the approved state method when they offer the composite premium option to small groups.

So a composite is a presentation layer, not a different rating engine. The state record adds that a composite offered to one Texas small employer must be made available to all; that is the record’s statement rather than a regulator sentence isolated for this post, so confirm it with an issuer rather than assuming it. When a quote arrives as tiers, the per-member arithmetic underneath still exists, and asking to see it is reasonable.

What gets filed with the department, and what stays at the issuer

The department sets out what has to be filed and what does not:

“State law does not limit the frequency of rate changes; however, rates must be just, fair, reasonable, and adequate. All rate changes for individual market plans must be filed. Any change to methodology for small group rates must be filed for approval with TDI (28 TAC §26.11).”

— Texas Department of Insurance health FAQ

That administrative-code reference is the department’s own published citation string; no administrative-code rule text was read for this post.

The statute adds an annual duty. Tex. Ins. Code § 1501.215(a) requires each small employer health benefit plan issuer to file an actuarial certification with the commissioner stating that its underwriting and rating methods comply with accepted actuarial practices, are uniformly applied to each small employer health benefit plan, and comply with the subchapter. Tex. Ins. Code § 1501.215(b) requires the issuer to keep a complete and detailed description of its rating and renewal underwriting practices at its principal place of business — and Tex. Ins. Code § 1501.215(c) makes that description proprietary and trade secret information.

The honest employer-facing summary: the method is filed and certified, the rate manual is not public. That is why a renewal review is a comparison of outcomes and structures rather than an audit of an issuer’s book.

A cooperative changes the unit that gets rated

Joining a health group cooperative changes which entity is being rated rather than which factors apply. Tex. Ins. Code § 1501.063(b) treats a cooperative of only small employers, only large employers, or both as a single employer under the code, and Tex. Ins. Code § 1501.063(b-1) and (b-2) then split the treatment according to whether a statutory election has been made — including, in terms, for any provision relating to premium rates and to issuance and renewal of coverage. Tex. Ins. Code § 1501.066(a) lets a cooperative elect instead “to treat each participating employer within the cooperative as a separate employer for purposes of rating”, subject to a notice requirement and a minimum duration set in Tex. Ins. Code § 1501.066(b) and (c).

Tex. Ins. Code § 1501.065 closes the door on selection inside the cooperative: it may not limit, restrict or condition membership based on “(1) risk characteristics of a group or of any member of a group; or (2) health status related factors, duration of coverage, or any similar characteristic.”

The sections that read live and cannot be applied as written

This is what trips up anyone reading the Texas statute alone. Most of Subchapter E carries the credit line Added by Acts 2003, 78th Leg., ch. 1274, Sec. 3, eff. April 1, 2005 with no later amendment, no repeal marker and no expiry language. It reads, on its face, like operative law.

Tex. Ins. Code § 1501.205 defines a “risk load” as a percentage above the applicable base premium rate charged to reflect the risk characteristics of that particular small employer group, and a risk characteristic there expressly includes a health status related factor and duration of coverage. Tex. Ins. Code § 1501.206(a)(2) permits a renewal adjustment “due to the claims experience, health status, or duration of coverage of the employees or dependents of employees of the small employer”. And Tex. Ins. Code § 1501.210(c)(2), quoted above, lists the age and gender of employees and dependents as a permitted case characteristic.

Set those beside 45 CFR 147.102(a)(2), quoted above, which says the rate must not vary by any other factor not described in paragraph (a)(1). This post reports both texts with their own citations and does not assert which prevails over the other.

What can be stated is the resolution the Texas Department of Insurance itself supplies. Its guidance names Texas, says federal regulations “do not preempt more narrow state law requirements,” relies on Tex. Ins. Code § 1501.206 to bar an individual-enrollee health status adjustment, and states that it anticipates the transition to the federal adjusted community rating methodology will trigger a change in rating methodology for most small group carriers in Texas — which is why the department expects a methodology filing. Rest your reading on that guidance rather than on the bare statute, and treat a proposal that appears to price your group on its own claims history as a question to ask out loud. If you want a second reading of one, send it over.
