Molecular pathology labs in Colorado are facing a huge number of denials. UnitedHealthcare and Anthem, often through Carelon, enforce tight prior authorization requirements, once-per-lifetime limits on germline tests, and strict test registry rules. Fortunately, Colorado’s new HB24-1149 law provides concrete leverage. It mandates gold-carding for labs with high approval rates, extends authorizations to a full year, and requires payers to name an alternative test when they deny a request.
Labs can protect revenue by tracking their own approval rates for exemption eligibility, flagging UHC Individual Exchange plans that skip pre‑auth, checking germline status before accessioning, and citing HB24-1149 in every appeal. A lab billing partner, like TransLabs, that knows Colorado payer policies and state law can embed these checks into intake and appeals, manage evolving rules seamlessly, and cut through denials so your team can focus on testing, not chasing paperwork.
Getting a denied molecular pathology claim is frustrating. You ran the test, the physician needed the answer, and now you’re busy writing an appeal instead of moving on to the next accession. This is the headache many laboratory billing teams across Colorado wrestle with in 2026.
Here’s the good news. Colorado passed a law that hands labs some real bargaining power against payer-side Laboratory Benefit Management (LBM) programs. Pair that with the latest Anthem and UnitedHealthcare (UHC) policy changes, along with laboratory billing services in Colorado, and you’ve got a proper compliance guide with solutions to protect your revenue.
Let’s discuss the impact of HB24-1149 on lab billing and ways to leverage it.
LBM is the toolkit payers use, such as prior authorization, frequency limits, and test registries, to control how much they spend on lab and genetic testing. Molecular pathology and genetic testing are always at risk. These tests are costly, complex, and growing fast, so insurers try to add stricter requirements for labs to get claims approved.
UnitedHealthcare and Anthem, working through Carelon Medical Benefits Management, both lean hard on prior authorization requirements to reduce spending. But 2026 changed matters for Colorado lab billing. A new state law now requires payers to make processes easy in specific and measurable ways. That’s a rare bit of good news for lab RCM teams.
House Bill 24-1149 is the prior authorization reform law, which took effect January 1, 2026, and it rewrites the rules for how payers and utilization review organizations in Colorado operate. This legislation aims to cut administrative friction while giving physicians and patients a stronger say in care decisions. The Colorado Medical Society considers it a genuine win for patients and physicians alike.
Now, here are the four HB24-1149 provisions in the table below that labs must note:
| Provision | What It Means for Labs |
|---|---|
| Gold-Carding (PA exemption) | Payers must offer an alternative to prior authorization, often an exemption, to labs that have kept a 95%+ approval rate over 12 months. |
| Extended authorization windows | Approved pre-auths now run a full year (or the length of treatment) instead of the old 180-day window, which is huge for ongoing molecular monitoring. |
| Actionable denials | If a payer denies a pre-auth, it must clearly mention an alternative test or service it would approve instead. |
| Annual prior authorization reviews | Payers must review their own pre-authorization lists every year and drop requirements for tests that get approved. |
UHC runs one of the most detailed genetic and molecular testing pre-auth programs in the industry. Most of it applies nationwide, but Colorado gets a few notable exceptions.
The fact is that the UnitedHealthcare Individual Exchange plans are subject to genetic and molecular testing pre-auth requirements in every state except Colorado. That carve-out has been in place for a while, and it’s still holding through 2026, even as UHC keeps expanding its prior authorization code list for other plan types (commercial and community plans picked up more codes in September 2025 and again in July 2026).
To stay on top of that, you must flag every UHC Individual Exchange plan in Colorado right away.
UHC’s Medicare Advantage Medical Policy for Molecular Pathology/Diagnostics (MMP210.35) carries strict, specific criteria. Two examples every lab should know:
Anthem hands its molecular and genetic testing utilization review to Carelon Medical Benefits Management, and Carelon isn’t shy about tightening the rules.
Anthem’s reimbursement policy titled “Genetic Tests: Once per Lifetime” has been in force since January 1, 2024. According to it, a person’s germline genotype doesn’t change over their lifetime, so Anthem only reimburses germline sequencing once per member. Effective July 1, 2026, Anthem expanded the list of procedure codes subject to this rule.
Here, reinterpreting old results or re-analyzing previously sequenced data isn’t separately reimbursable, even when the clinical picture changes. Build eligibility-history checks into your LIS before you accession a repeat germline order. Doing so helps you confirm if a patient is eligible for the treatment.
Real-time laboratory eligibility verification services help you check a patient’s germline status before testing, which prevents avoidable claim denials and protects your revenue.
| CPT Code | Description |
|---|---|
| 0556U | Pathogen-specific DNA/RNA panel, 12 targets, real-time PCR |
| 0563U | 11 viral + 4 bacterial targets, qualitative RT-PCR |
| 0564U | 10 viral + 4 bacterial targets, qualitative RT-PCR |
Managing multiple payer rules, along with learning and utilizing HB24-1149 in billing, requires dedicated staff who take time to understand these policies. Hiring in-house billing and compliance staff can be costly. You can reduce that overhead by outsourcing your laboratory billing to specialists, like TransLabs. These specialists not only know Colorado pre-authorization laws, along with separate UHC and Anthem policies, but also have hands-on experience implementing them in revenue cycle management.
Such a billing partnership helps you recover your revenue and stay on top of regulatory compliance. It protects your finances and secures you legally.
