Colorado's New Rules to Stop Dental Insurers from Selling Out Your Dentist

What This Bill Actually Does

If you've ever worked in medical billing, you know about the dreaded 'silent PPO' or leased network. Here is how it works under current law: A dentist signs a contract with a major insurance carrier, agreeing to provide services at a contractually agreed-upon discount. Then, the insurance carrier turns around and signs a third-party network lease agreement with another, often smaller or out-of-state, benefits company. They essentially sell access to the dentist's discounted rates. The dentist usually has no idea this happened until a patient walks in with an unfamiliar insurance card, expecting the major carrier's discount. If the dentist complains or refuses to honor the third-party rate, the major carrier can retaliate by kicking the dentist out of their primary network entirely.

HB26-1070 completely flips this power dynamic. The bill strictly prohibits insurance carriers from leasing out a dentist's services and discounts unless the dentist provides affirmative consent. That means a signature—electronic or physical—explicitly saying they want to participate in the third-party network. Most importantly, the bill includes an anti-retaliation clause. A carrier cannot cancel a contract, or refuse to sign a new provider, solely because the dentist refuses to let their discounts be farmed out to third parties.

If a dentist does choose to opt into these third-party agreements, the bill lays out a strict set of ground rules the carrier must follow. They have to allow the dentist to contract directly with the third party if they prefer. The carrier must also maintain a website, updated every 90 days, listing all third parties that have access to the network. Furthermore, any Explanation of Payment (EOP) sent to the dentist must clearly identify where the contractual discount came from. The bill does carve out a few practical exemptions: these rules don't apply to state-sponsored programs like Medicaid or the Children's Basic Health Plan, nor do they apply to entities operating under the exact same brand licensee program as the main carrier.

What It Means for You

If you aren't a dentist or an insurance broker, you might be wondering why network leasing matters to you. It matters because it directly impacts whether you can keep seeing your family dentist. When dentists are forced into 'silent networks' they didn't sign up for, they take massive, unexpected financial hits on those procedures. Over time, the administrative headache and lost revenue cause many great dental practices to simply throw up their hands and stop taking insurance altogether, moving to a cash-only or out-of-network model.

By giving dentists control over who gets access to their discounted rates, HB26-1070 aims to stabilize the dental market. It removes a major source of friction between providers and carriers. For you, as a patient, this means fewer surprises at the front desk. If your employer switches your dental coverage to a lesser-known third-party administrator, you won't get caught in the middle of a billing dispute because your dentist will have actively chosen whether or not to accept that specific network's terms.

Here is what you should do to protect yourself and your family as this shifts:

• Check your insurance card: Look closely at your dental plan. Is it directly through a major carrier, or does it list a third-party administrator network?
• Talk to your HR department: If your company uses a leased-network dental plan to save money on benefits, ask them to verify network adequacy for 2027. Some dentists may opt out of these sub-networks once they have the legal right to do so.
• Communicate with your dentist: Next time you are in the chair, ask your dentist's billing coordinator which networks they plan to stay in. They will appreciate that you actually understand how the system works.

What It Means for Your Business

If you own or manage a dental practice in Colorado, HB26-1070 is one of the most consequential pieces of healthcare legislation you will see this year. For years, you have likely dealt with the frustration of mysterious remittances where a third party takes a steep network discount, and you have no idea how they accessed your fee schedule. This bill hands the steering wheel back to you. Carriers can no longer bury opt-ins in the fine print of a 50-page master contract; they need your affirmative consent to lease your rates. Better yet, the anti-retaliation provisions mean you can finally say 'no' to unprofitable third-party networks without losing your primary contracts.

For employers and business owners outside of healthcare who purchase dental benefits for their teams, this bill requires a strategic pivot. If you have been relying on cheap, third-party umbrella networks to provide dental coverage for your employees, you need to prepare for the reality that those networks might shrink. Dentists who previously accepted your employees' coverage through a forced lease agreement might choose to opt out once the law takes effect. You will need to keep a close eye on provider directories to ensure your employees actually have places to use their benefits.

Here are three concrete steps business owners should take right now:

• For Dental Practices - Audit your contracts: Pull your current carrier agreements and identify any third-party lease clauses. Prepare a list of which leased networks are profitable and which you plan to drop once the bill takes effect (likely August 12, 2026).
• For Dental Practices - Update your billing workflows: Starting late 2026, the law requires third parties to explicitly identify the source of their discount on every remittance. Train your billing staff to flag and reject any discounted payments that don't comply with this transparency rule.
• For General Employers - Review your benefits package: If your company's open enrollment falls in Q4 2026, meet with your benefits broker now. Ask them directly how HB26-1070 will impact the size and quality of the dental network you are offering your staff.

Follow the Money

The fiscal impact of this bill is refreshingly straightforward and incredibly cheap for taxpayers. According to the nonpartisan Legislative Council Staff, HB26-1070 will cost the state exactly $0 in both new revenue and expenditures for the upcoming fiscal years.

The Division of Insurance (within the Department of Regulatory Agencies) anticipates a very minor bump in their workload. They will be responsible for handling complaints from dental providers if insurance carriers fail to comply with the new affirmative consent and transparency rules. However, the state has determined that this slight increase in regulatory enforcement can easily be absorbed using their existing staff and current budget appropriations. In short, this is a major regulatory shift for the private market that requires no new taxpayer funding.

Where This Bill Stands

This bill is moving incredibly fast and facing almost zero institutional friction. Introduced in late January 2026, it cleared the House Health & Human Services Committee and passed the full House on Second Reading with absolutely no amendments by February 19, 2026.

Because it boasts bipartisan prime sponsorship (Rep. Hartsook and Sen. Jodeh) and sailed through its early hurdles untouched, it is highly likely to become law. It will take a final vote in the House before crossing over to the Senate. Assuming it passes and the Governor signs it, the new rules will take effect on August 12, 2026 (assuming the legislature adjourns on May 13 as planned). Importantly, it will apply to any dental network contract entered into, or renewed, on or after that date.
