What State Law Requires a Group Plan to Cover in Colorado

Colorado writes its coverage requirements into C.R.S. § 10-16-104 and a run of companion sections, and they reach group plans directly. They sit on top of the federal essential health benefits package rather than replacing it. The harder part is that some of Colorado’s newer requirements reach a small group plan only on a condition.

The duty runs to the plan and the carrier, not to you

Before any individual requirement, the grammar of Colorado’s mandates is worth noticing, because it changes what an employer is actually responsible for.

Read the opening of almost any subsection of § 10-16-104 and the subject of the sentence is a policy, a contract, a health benefit plan or a carrier. It is the plan that shall provide coverage. An employer buying a fully-insured Colorado small group plan is not the party the mandate commands; it is buying a product already built to satisfy one.

That has a consequence and a limit. The consequence is that you do not need to specify these benefits when you shop, because a compliant Colorado small group product carries them or cannot be sold. The limit is that the protection travels with the fully-insured product — an arrangement structured as self-funded sits under different rules, which is the first thing to establish about any proposal before comparing its benefits against this list.

Newborns, maternity and complications of pregnancy — three provisions around one event

Colorado treats the arrival of a child as three separate requirements, and the seams between them are where coverage questions arise.

The first reaches the child directly. C.R.S. § 10-16-104(1) requires that all group and individual sickness and accident insurance policies and service or indemnity contracts provide coverage for a dependent newborn child of the insured or subscriber from the moment of birth, and the requirement extends to minimum hospital stays following delivery and to congenital defects and birth abnormalities.

The second reaches the parent’s own care where something goes wrong. C.R.S. § 10-16-104(2) requires coverage for a sickness or disease which is a complication of pregnancy or childbirth in the same manner as any other similar sickness or disease is otherwise covered under the policy or contract. It is a parity rule: the plan does not get to treat a pregnancy complication as a category of its own.

The third is the ordinary case. C.R.S. § 10-16-104(3)(a)(I)(A) requires group sickness and accident policies issued to an employer to insure against the expense of normal pregnancy and childbirth — and note that this one is written specifically about policies issued to an employer, which is exactly the shape of a group plan.

Screening, oral cancer drugs and off-label prescribing are three different kinds of rule

Group these together and it becomes obvious that Colorado is not simply listing conditions. It is using three distinct drafting tools.

A flat requirement: C.R.S. § 10-16-104(10) requires all individual and all group sickness and accident policies, other than supplemental policies covering a specified disease or other limited benefit, to provide coverage for annual screening for the early detection of prostate cancer.

A parity requirement: C.R.S. § 10-16-104(21) applies where the plan already covers cancer chemotherapy, and then requires coverage for prescribed, orally administered anticancer medication — cost-sharing parity between a drug taken by mouth and one delivered by infusion for the same purpose. It creates no new benefit category; it stops one delivery route being priced worse than another.

A non-exclusion requirement: C.R.S. § 10-16-104.6(1) provides that a plan covering prescription drugs shall not limit or exclude coverage for any drug approved by the FDA for use in the treatment of cancer on the basis that the drug has not been approved by the FDA for the treatment of the specific type of cancer for which the drug is prescribed, where the use is recognized in the authoritative reference compendia.

Three requirements, three mechanics, and only the first would appear on a benefit summary as a line item. The others are rules about how the plan may behave.

Diabetes, vaccination and clinical trial costs — and the phrase that decides their reach

The next group is where the applicability language starts to matter enough to quote.

C.R.S. § 10-16-104(13) reaches Any health benefit plan, except supplemental policies covering a specified disease or other limited benefit, that provides hospital, surgical, or medical expense insurance and requires coverage for diabetes including equipment, supplies, and outpatient self-management training and education — medical nutrition therapy included where prescribed. The self-management training half is the part people miss: it is not only the meter and the strips.

C.R.S. § 10-16-104(17) requires all individual and all group sickness and accident policies to provide coverage for the full cost of human papillomavirus vaccination.

C.R.S. § 10-16-104(20) requires that all individual and group health benefit plans provide coverage for routine patient care costs that a policy or certificate holder, or his or her dependent, receives during a clinical trial — the provision that separates research costs from the ordinary care delivered alongside them.

Notice the two different reaches in play. Some subsections speak of policies of sickness and accident insurance; others reach any health benefit plan. The second is broader, and it is the phrase that carries a requirement through to a small group plan without a market carve-out.

Dependents under twenty-six, and contraception dispensed a year at a time

Two companion sections outside § 10-16-104 itself are among the most used, and both are written as duties on the carrier.

C.R.S. § 10-16-104.3(1): A carrier that offers a health benefit plan in the state and that makes dependent coverage for children available under the health benefit plan shall make the coverage available for a child who is under twenty-six years of age. Colorado writes it without regard to residency, financial dependence, marital or civil union status, student status or employment status — so an adult child who has moved out, married or taken a job elsewhere is not thereby excluded.

C.R.S. § 10-16-104.2(2) requires that a carrier, or a pharmacy benefit management firm acting for it, cover and reimburse the single dispensing or furnishing of contraception intended to last the covered person for a duration of twelve months, dispensed at one time. It is a dispensing rule riding on coverage already required, and employees notice it at the pharmacy counter rather than in a benefit booklet.

Court-ordered treatment and gender-affirming care reach the plan differently

Put these side by side and the difference in drafting is the lesson.

C.R.S. § 10-16-104.7(1) provides that an individual or group health benefit plan that provides coverage for treatment of a substance use disorder must provide coverage for such treatment regardless of whether the treatment is voluntary or court-ordered. C.R.S. § 10-16-104.8(1) does the same for behavioral, mental health, or substance use disorder services. Both are conditioned on the plan covering those services in the first place, and § 10-16-104.7(2) says in terms that the section does not itself require a plan to cover substance use disorder treatment. They are non-discrimination rules on an existing benefit, and describing them as mandates to cover treatment would overstate what they do.

C.R.S. § 10-16-104(30) is drafted the other way. Subject to the requirements set out in subsection (30)(d) of that section, it provides that all health benefit plans issued or renewed in the state shall provide coverage for gender-affirming health care, and bars denial or limitation of medically necessary care prescribed in accordance with generally accepted standards of care. It carries no defrayal condition and no market-segment carve-out in its own text, which is what separates it from the conditional group described below.

A heading that reads like a mandate over text that is an offer

This is the clearest example in Colorado law of why a heading is not a rule, and it changes what you should check on a proposal.

C.R.S. § 10-16-104(8) is headed in a way that reads like a hospice benefit requirement. The operative text says that no individual or group policy of sickness and accident insurance shall be sold in this state unless a policyholder under such policy or plan is offered the opportunity to purchase coverage for benefits for the costs of home health services and hospice care which have been recommended by a physician as medically necessary.

What Colorado requires is the offer. A Colorado group plan can satisfy this subsection and carry no hospice benefit, if the offer was made and not taken. So home health and hospice belong on the list of things to ask about when you compare proposals for group health coverage, not on the list you can assume.

Why a real Colorado requirement can still not reach your small group plan

Here is the machinery that makes this question harder in Colorado than in most states, and it is the thing worth understanding before you trust any third-party list of Colorado mandates.

Colorado’s newer coverage requirements are routinely drafted to reach large employer plans on a fixed date, and to reach individual and small group plans only once a condition is met. The shape of the condition, in the statute’s own words:

(V) With respect to individual and small group health benefit plans, the division shall: (A) Review the actuarial review conducted pursuant to section 10-16-155.5 and submit to the federal department of health and human services the division’s determination as to whether the benefit specified in this subsection (3)(e) is in addition to essential health benefits and would be subject to defrayal by the state pursuant to 42 U.S.C. sec. 18031 (d)(3)(B); and (B) Request that the federal department of health and human services confirm the division’s determination within sixty days after receipt of the division’s request and submission of its determination.

This is not a Colorado invention. It is Colorado responding to a federal rule about who pays when a state requires a benefit beyond the essential health benefits. 45 C.F.R. § 155.170 provides that a State “must make payments in accordance with paragraph (b) of this section to defray the cost of any State-required benefits in addition to the EHB,” and that “The State will identify which State-required benefits are in addition to the EHB.”

Two things follow. The same conditional structure appears across the newer subsections of § 10-16-104, so a list of Colorado mandates assembled from headings or from a third-party compilation will not separate the ones in force for a small group plan from the ones still waiting on a determination. And the federal test itself is dated: the regulation’s treatment of which state-required benefits count as essential health benefits changes for plan years beginning on or after January 1, 2028, so an answer written as though today’s test is permanent will be wrong on a date already in the regulation.

This post therefore stays with the subsections whose own applicability sentence was read and holds, and says nothing in either direction about the conditional group. If you want that checked against how this brand works in Colorado, our state page is the place to start.

What the federal package already puts in every small group plan

Colorado’s requirements are additions, not the foundation. The foundation is federal, and it applies to coverage in the small group market by its own terms: 45 C.F.R. § 147.150 requires that a health insurance issuer offering coverage in the individual or small group market must ensure that such coverage includes the essential health benefits package.

45 C.F.R. § 156.110(a) sets out what that package is built from. The regulation’s own lead-in reads: An EHB-benchmark plan must meet the following standards: (a) EHB coverage. Provide coverage of at least the following categories of benefits: — and the categories it names are ambulatory patient services; emergency services; hospitalization; maternity and newborn care; mental health and substance use disorder services, including behavioral health treatment; prescription drugs; rehabilitative and habilitative services and devices; laboratory services; preventive and wellness services and chronic disease management; and pediatric services, including oral and vision care.

That last category is the one employers ask about most, because pediatric oral and vision care sits inside a medical plan while adult dental and vision coverage are separate products with their own rules. The same regulation also requires an appropriate balance among the categories, so that benefits are not unduly weighted toward any one of them.

Where this leaves a Colorado employer

Colorado’s coverage requirements are real, are enforceable against the carrier, and reach past the federal floor — and the list you find on a third-party page is probably wrong at the edges, because it was assembled from headings rather than applicability sentences.

Three checks do most of the work. Confirm the proposal is a fully-insured Colorado small group product. Ask specifically about home health and hospice, because that one is an offer. And treat any list of Colorado mandates as a starting point for questions rather than a specification — including this one.
