Washington State insurance covers braces in some situations but not others, and the dividing line is almost always medical necessity rather than cosmetic improvement. Apple Health (the state’s Medicaid program) pays for braces for enrollees 20 and under when a child’s bite problem is severe enough to meet a specific clinical score. Private individual and small-group plans sold in Washington must include medically necessary orthodontics for children as part of their pediatric dental benefits. Adult orthodontic coverage, by contrast, is rare under any program and is almost always an optional add-on rather than a required benefit.
Braces for Kids on Apple Health
Apple Health covers orthodontic treatment for enrolled clients who are 20 years old or younger.1Washington State Health Care Authority. How Do I Get Dental Care The program pays for braces when the patient has serious dental needs that go beyond appearance, and prior authorization from the Health Care Authority (HCA) is required before treatment begins.2Washington State Health Care Authority. Orthodontic Services Billing Guide – January 1, 2025
You also have to use a provider contracted with the HCA. If your orthodontist is out of network, the state will not reimburse the treatment, no matter how clear the clinical need is. Confirm network status before scheduling an evaluation.
Adults 21 and older are not eligible for orthodontic coverage through Apple Health. The HCA explicitly lists braces among the dental services it does not cover for adults.1Washington State Health Care Authority. How Do I Get Dental Care The only adult exceptions involve surgical procedures for conditions like cleft palate or other congenital anomalies, which fall under different benefit categories than standard orthodontics.
How Apple Health Decides a Case Is Medically Necessary
Apple Health does not cover braces for aesthetic reasons. Every case goes through a clinical review under Washington Administrative Code 182-535A-0040.3Cornell Law School. Washington Administrative Code 182-535A-0040 – Orthodontic Treatment and Orthodontic-Related Services Reviewers use the Washington Modified Handicapping Labio-Lingual Deviation (HLD) Index, a scoring tool that assigns numerical values to overjets, overbites, crossbites, tooth displacement, open bites, and similar findings.
A patient needs a Modified HLD Index score of 25 or higher for the state to authorize treatment.3Cornell Law School. Washington Administrative Code 182-535A-0040 – Orthodontic Treatment and Orthodontic-Related Services Certain conditions bypass the scoring entirely and qualify automatically:
- Cleft palate.
- Deep impinging bite where the bite causes visible tissue damage, not just contact with the palate.
- Anterior crossbite with gingival recession.
- Severe traumatic deviation from accidents, tumors, or similar causes.
- Overjet of 9 mm or greater, or a reverse overjet of 3.5 mm or greater.
- Impacted maxillary central incisor.
Most Apple Health orthodontic claims succeed or fail at this threshold. If a child’s condition doesn’t reach 25 points and doesn’t fall into one of the automatic categories, the state will deny coverage, regardless of what you or the orthodontist think about the benefits of treatment. In borderline cases, the provider’s written explanation of how the clinical findings connect to the HLD criteria can make the difference.
Private Plans Bought in Washington
Private health plans sold on Washington’s individual and small-group markets must include pediatric oral services as part of the essential health benefits required by the Affordable Care Act.4National Center for Biotechnology Information (NCBI). Changes in Pediatric Dental Coverage and Visits Following the Implementation of the Affordable Care Act Washington’s benchmark plan specifically includes medically necessary orthodontics within that pediatric dental category.5Washington State Legislature. WAC 284-43-5702 – Essential Health Benefit Category – Pediatric Oral Services So an individual or small-group plan cannot flatly exclude braces for a child when a clinical need exists, though the plan’s own definition of medical necessity and its cost-sharing structure determine what you actually pay.
Adults are in a different position. No Washington law requires private insurers to cover braces for adults. Some higher-tier dental policies and optional riders include adult orthodontics, but these are voluntary insurer additions, not state mandates. Adults who want coverage typically need a standalone dental plan with an orthodontic benefit, and even those often cap lifetime orthodontic payments between $1,000 and $2,000, which barely dents the total cost of treatment.
For children covered under private plans, expect cost-sharing even after treatment is approved. Deductibles, coinsurance, and annual or lifetime benefit caps vary. Read the Summary of Benefits and Coverage for your specific plan before committing, paying close attention to whether orthodontics has a separate deductible from general dental.
Why Your Employer Plan Might Not Follow Washington’s Rules
If you get coverage through a large employer, there’s a real chance your plan is self-funded, meaning your employer pays claims directly rather than buying a traditional insurance policy. Self-funded plans are governed by the federal Employee Retirement Income Security Act, not Washington state law.6U.S. Department of Labor. ERISA ERISA preempts state benefit mandates, so Washington’s pediatric dental rules do not apply to a self-funded employer plan.
Your insurance card will look the same either way, so you may not realize the difference until a claim is denied. Check your Summary Plan Description or ask HR directly. Self-funded plans can and often do cover orthodontics, but they aren’t required to, and if they deny a claim your appeals route runs through the plan’s internal process and federal ERISA procedures rather than through the Washington Office of the Insurance Commissioner.6U.S. Department of Labor. ERISA
What You’ll Actually Pay
Insurance rarely pays the full tab. Traditional metal braces generally run $3,000 to $7,500 depending on the complexity of the case and where you live in the state. Clear aligners run roughly $3,500 to $8,500. Lingual braces, which attach to the back of the teeth, are the most expensive and can exceed $10,000.
Apple Health covers approved treatment in full for eligible kids. Private plans frequently cap orthodontic benefits at a fixed dollar amount, so if your plan has a $1,500 lifetime orthodontic maximum and treatment costs $5,000, the remaining $3,500 is yours. Many orthodontists offer interest-free payment plans for the balance; ask about this at the initial consultation.
The IRS classifies braces as a deductible medical expense, which opens up several ways to lower the real cost.7Internal Revenue Service. Publication 502, Medical and Dental Expenses A Health Savings Account tied to a high-deductible health plan lets you pay for braces with pre-tax dollars; the 2026 HSA contribution limits are $4,400 for individual coverage and $8,750 for family coverage.8Internal Revenue Service. Revenue Procedure 2025-19 – 2026 Inflation Adjusted Items for Health Savings Accounts A health care Flexible Spending Account works similarly, with a 2026 contribution limit of $3,400, though FSA funds generally must be used within the plan year or a short grace period.
Without an HSA or FSA, you can still deduct orthodontic costs on Schedule A, but only the portion of your total medical and dental expenses exceeding 7.5% of your adjusted gross income counts.9Internal Revenue Service. Topic No. 502, Medical and Dental Expenses For a family earning $80,000, the first $6,000 in medical expenses produces no deduction, so this route mainly helps if you have significant medical costs on top of the braces.
Getting Treatment Approved
Both Apple Health and most private insurers require prior authorization before orthodontic treatment begins. For Apple Health, your orthodontist’s office submits the HCA 13-835 form along with panoramic X-rays, intraoral photographs, and a narrative explaining how the patient meets the HLD criteria.10Cornell Law School. Washington Administrative Code 182-552-1325 – Prior Authorization
For Apple Health enrollees in a managed care organization, the plan must decide a standard prior authorization request within seven calendar days of receiving it.11Washington State Health Care Authority. Updates to Prior Authorization Timeframes Expedited requests for urgent situations must be decided within 72 hours, and if the reviewer needs more information, the provider has four calendar days to respond. Private insurers set their own timelines, which should be spelled out in your plan documents.
Once approved, limited orthodontic treatment under Apple Health must be completed within twelve months of appliance placement. Longer treatment requires a limitation extension request through the HCA.2Washington State Health Care Authority. Orthodontic Services Billing Guide – January 1, 2025
If Your Claim Is Denied
A denial is not the end. The written denial notice must include the specific reason and instructions for appealing. For Apple Health denials, you can request a fair hearing through the HCA. For private plan denials, start with the plan’s internal appeals process, which lets you submit additional clinical evidence or a second opinion from another orthodontist.
If a private insurer upholds the denial after internal review, you can request an external review through the federal process administered by MAXIMUS. You have four months from the date you receive the final internal denial to file. A standard external review must be completed within 45 days, and the decision is final; an expedited review for urgent situations takes 72 hours.12Centers for Medicare & Medicaid Services. HHS-Administered Federal External Review Process for Health Insurance Coverage
Washington residents with fully insured plans (not self-funded employer plans) can also file a complaint with the Office of the Insurance Commissioner if they believe the insurer violated the law or handled a claim unfairly. The OIC will forward the complaint to the insurer and require a response.13Washington Office of the Insurance Commissioner. Complaints, Appeals and Fraud This is separate from the formal appeals process but can sometimes push a stalled claim toward resolution.
Keeping Coverage If You Change Jobs Mid-Treatment
Orthodontic treatment often spans one to two years, which creates a real problem if you or a covered family member loses employer-sponsored insurance partway through. COBRA requires most private employers with 20 or more employees to offer temporary continuation of the same group health coverage after a qualifying event like job loss or a reduction in hours.14U.S. Department of Labor. An Employee’s Guide to Health Benefits Under COBRA That continuation must include dental and orthodontic benefits if those were part of your plan.
The catch is cost. Under COBRA, you pay the full premium your employer previously subsidized, plus a 2% administrative fee. For a family dental plan, that can mean several hundred dollars a month just to maintain coverage. But if your child is mid-treatment with thousands of dollars in remaining benefits, paying COBRA premiums for the duration can still cost less than paying the orthodontist out of pocket. Run the numbers before you decide.
