Nevada AB 223 Medicaid Waiver: Billing Expanded Dental Coverage for Adults with Diabetes
Not long ago, treating an adult Medicaid patient in Nevada meant one of two things: pull the tooth or manage the pain. That was it. There was no coverage for cleanings, fillings, or gum therapy for most adults on Medicaid, no matter how badly they needed the care.
Well, that’s no longer the case now.
Thanks to Nevada AB 223 Medicaid Waiver. It’s a federal waiver approval and a benefits rollout that took effect July 1, 2026. With it, more than 374,500 Nevada adults now hold dental coverage they never had before. For dental claims related to patients with diabetes, the shift is even bigger. New coverage means new billing rules, caps, and denial codes.
This guide walks you through this scenario, discussing which patients qualify, what it covers, which codes you can bill, how the $1,000 cap works, and how to use Nevada dental billing services to keep your claims from bouncing back. Let’s dig in.
What is Nevada AB 223 Medicaid Waiver?
Assembly Bill 223 is a 2019 Nevada law that asked the state to get federal funding approved for dental coverage aimed at Medicaid adults with diabetes. It led to the Whole Mouth Whole Body Connection for Adults with Diabetes, a Section 1115 demonstration waiver that CMS approved on June 21, 2024.
The table below explains the complete timeline of how the law came into effect and coverage expanded to dental benefits:

What is the Whole Mouth Whole Body Connection?
The Whole Mouth Whole Body Connection is the official name of Nevada’s waiver pilot. The program covers non-pregnant Medicaid adults, ages 21 through 64, who have type 1 or type 2 diabetes, and it delivers care through participating Federally Qualified Health Centers (FQHCs) and Tribal Health Centers with dental clinics.
A few details about it your billing team must know:
- Five encounters per demonstration year: There’s no cap on covered services when they’re clinically appropriate. Encounters don’t roll over into another year and can’t be shared with another patient.
- No cost sharing: Patients owe nothing for waiver-covered services. There aren’t any copays or premiums.
- Location: Care from a non-participating provider isn’t reimbursed under the demonstration. Patients in urban Clark and Washoe Counties get benefits through the state’s Dental Benefits Administrator, Liberty Dental. Others get benefits through the fee-for-service model.
Who Qualifies for This Expanded Dental Coverage?
As of August 2026, essentially every Medicaid-enrolled adult 21 and older gained preventive and diagnostic coverage, while adults with diabetes can tap the richer waiver pilot through participating health centers.
These are the beneficiaries of this coverage:
- Non-pregnant adults 21 to 64 with a diabetes diagnosis. Fuller benefit package, mirroring what pregnant members get, but only at participating FQHCs and Tribal Health Centers.
- All adults 21+, no diagnosis required. Routine care falls under a $1,000 annual cap.
- Pregnant members keep expanded with uncapped benefits. Members 20 and younger keep full EPSDT dental, including prior authorized orthodontics. Services through Indian Health Services and Tribes also don’t fall within the cap.
According to the State Dental Officer, Dr. Keith Benson, this dental benefits expansion is a welcoming step for the population across The Silver State, enabling them to get cleanings, exams, and prompt treatment to avoid painful emergencies and financial strain. This also benefits dental practices billing in Nevada, as they get the opportunity to treat more patients and maximize revenue streams.
What Dental Services Are Covered by Nevada Medicaid?
Exams, cleanings, silver diamine fluoride, gum treatment, fillings, and crowns now fall under the $1,000 annual limit, while emergencies, dentures, and pregnancy-related care carry no cap at all.
Here’s the full breakdown, according to the state’s member guidance and Web Announcement 3955:
| Covered Benefit | Annual Limit Status |

| Two periodic (6-month) exams |
|
| Two cleanings (prophylaxis) | |
| One comprehensive exam every 3 years | |
| Silver diamine fluoride treatment | |
| Gum (periodontal) treatment | |
| Fillings and crowns | |
| Treatment for pain or emergencies |
|
| Partial and full dentures | |

Services Still Not Covered Under Expansion
For standard adults under the statewide expansion, endodontics and non-emergency extractions remain non-covered. And the one thing to note is that the waiver pilot’s benefit package mirrors the pregnant adult package, which does include endodontic services for qualifying diabetic patients at participating health centers.

Nevada Medicaid’s $1,000 Annual Cap on Adult Dental Services
Nevada Medicaid’s $1,000 annual cap is a limit on expanded adult services per calendar year, calculated against the fee-for-service fee schedule, and it resets every January 1.
While it seems like a little number, it can cause big revenue leaks:
- A couple of exams, two cleanings, some SDF, and a crown or two can consume the whole cap by summer. Q3 and Q4 appointments are prime territory for maxed-out patients.
- The expansion launched July 1, 2026, but the cap runs on the calendar year. Don’t assume the first cycle gives anyone eighteen months of benefits.
- Emergencies, palliative care, and dentures dodge the cap entirely. The same applies for pregnant members and IDD waiver recipients, who have their own limit tiers.
What Is Error Code 5751?
Nevada Medicaid Error Code 5751 flags the $1,000 allowed per calendar year limit. When a claim exceeds the patient’s cap, Medicaid posts a partial claim, paying up to the maximum amount, and leaving the rest of it.
That leftover balance is where practices risk losing revenue. Under MSM Chapter 100, Section 105.3 C, the patient is financially responsible for the coverage only if you met the written requirements beforehand. If you haven’t obtained a signed consent, you can’t bill the patient for the remaining amount, leading your practice to absorb the revenue loss.
This sounds frustrating. But here is what you can do proactively: get written financial consent before treatment, spelling out that the patient owes anything past the $1,000 mark. Your posting team should also flag every remit carrying 5751 the moment it lands, so the balance shifts to patient responsibility instead of a write-off.
How Do You Bill Nevada Medicaid for Adult Dental Claims in 2026?
Nevada’s dental landscape just changed more in two years than it did in two decades. AB 223 laid the foundation back in 2019, CMS approved it in 2024, and the July 2026 expansion finally provided some considerable benefits to patients. For your dental practice, that’s a wave of new appointments and a whole lot of workload.
You can win here if you verify benefits on every visit, track that $1,000 cap for every treatment, and obtain patient consent before every treatment.
But managing dual claim pathways, partial claims, and shifting manuals is a lot for any front desk. If your team would rather focus on patients than remittance codes, partnering with a specialized dental billing company like TransDontics keeps your claims clean, your caps tracked, and your cash flow steady. Your chairs stay full, and your revenue stays smooth.
