Does Medicaid Cover Braces? Rules for Kids, Teens, and Adults

The federal rule behind children’s braces

Medicaid is run by each state, but federal law sets a floor for children. That floor is the Early and Periodic Screening, Diagnostic, and Treatment benefit, usually shortened to EPSDT. It applies to every Medicaid enrollee under age 21.

According to Medicaid.gov’s EPSDT page, states must cover the services a child needs to correct and ameliorate health conditions. The dental part of that benefit includes care for pain and infection, restoring teeth, keeping teeth healthy, and medically necessary orthodontic services. The rules themselves are written in federal regulations at 42 CFR part 441, subpart B.

Two things follow from this. First, a state cannot simply leave orthodontics out for kids. Second, the state, not the family or the orthodontist, decides whether a particular child’s case is medically necessary. Medicaid.gov’s dental care page says this directly: states determine medical necessity.

The protection ends at 21. That is why timing matters for older teens, which we cover in the approval section below.

What medically necessary means for a bite

Orthodontists use the word malocclusion for teeth and jaws that do not line up. Many malocclusions are mild. Medicaid is looking for one that is handicapping, meaning it gets in the way of normal function or causes damage.

Problems that tend to point toward medical necessity include:

• A cleft lip or palate, or another birth difference of the jaw.
• Lower front teeth biting into the roof of the mouth and injuring the gums.
• Front teeth that stick out far past the lower teeth, so the lips cannot close over them.
• A crossbite that is wearing down teeth or damaging gum tissue.
• Teeth that cannot come in because they are blocked (impacted), especially the upper canines.
• Jaw injuries or disease that changed how the teeth meet.
• Trouble chewing or speaking that a doctor or speech therapist links to the bite.

Problems that usually do not qualify on their own include small gaps, mild crowding, slightly rotated teeth, and wanting a straighter smile for photos. Those are real concerns for a teenager, but Medicaid treats them as cosmetic.

How states score a bite with the HLD index

Most states use some version of the Handicapping Labio-Lingual Deviation index, or HLD. It turns a bite into a number so reviewers can compare cases the same way.

The orthodontist measures things like overjet (how far upper teeth stick out), overbite, open bite, crowding, and missing or blocked teeth, often with a small gauge or ruler on the teeth or on a model. Each finding adds points. A total at or above the state’s cutoff supports approval.

Many versions also list automatic qualifiers. These are conditions so serious that the case qualifies even if the point total is low. A California State Hearings Division note describing Medi-Cal Dental rules lists five of them: cleft palate deformities, a deep overbite that is destroying palate tissue, a front-tooth crossbite that is destroying soft tissue, overjet over 9 mm with lips that cannot close (or reverse overjet over 3.5 mm with chewing and speech problems), and severe traumatic deviations. That note also says study models must confirm the score.

Some states also accept a written narrative. If a child scores just under the line but has a documented medical problem, such as pain, tissue damage, or a speech issue, the orthodontist or the child’s doctor can explain why treatment is still necessary.

State cutoffs vary

There is no single national score. Each state, and sometimes each Medicaid dental plan within a state, publishes its own form and cutoff. The examples below show how much the rules can differ. Always ask your child’s orthodontist or your plan for the current version.

Because reviewers re-score the records themselves, the orthodontist’s number and the state’s number can differ. The California hearings note observes that in many disputed cases the treating dentist scored 26 or more while the state’s consultant scored lower. That is one reason good records and an appeal can matter.

The prior approval process, step by step

Medicaid will not pay for braces that were put on before approval. The process usually runs like this:

1. Get a dental checkup and referral. Your child’s Medicaid dentist can spot a bite problem and refer you. Some states require a referral; others let you go straight to an orthodontist.
2. Find an orthodontist who takes your child’s Medicaid plan. Call the member services number on the Medicaid card, or use the plan’s provider directory. Ask, “Do you take new Medicaid orthodontic patients?”
3. Attend the evaluation. The orthodontist takes photos, X-rays, and either physical or digital models, and fills out the state’s scoring form.
4. The office sends a prior authorization request. It goes to the state or your managed care dental plan with the score and records.
5. Wait for the written decision. If approved, treatment can begin. If denied, the notice must explain why and how to appeal.
6. Keep coverage active. Braces take about one to three years. Renew Medicaid on time so payments to the orthodontist are not interrupted.

If your family does not have Medicaid yet, see our step-by-step guide on how to apply for Medicaid. Applying is free, and children often qualify at higher incomes than adults.

Does Medicaid cover braces for adults?

Rarely. Once someone turns 21, the EPSDT rule no longer applies. Medicaid.gov says states have flexibility to decide what dental benefits adults get, and there are no minimum requirements for adult dental coverage. Some states offer only emergency extractions; others cover cleanings and fillings. Orthodontics is almost never part of an adult package.

The exceptions tend to be medical rather than dental. An adult who needs jaw surgery (orthognathic surgery) after an injury, or because of a severe jaw deformity, may need braces before and after the operation. In some states, that combined treatment can be reviewed as part of the surgery. It still needs prior approval and strong medical records.

Appealing a denial

A denial is not always the end. Many families win on appeal when new records or a doctor’s letter show a real health problem. Your rights depend on whether your child’s dental care runs through a managed care plan or straight through the state.

These limits come from federal rules on managed care appeals and fair hearings. Your denial notice will list the exact date for your state, so go by the notice.

To build a stronger appeal:

• Ask the orthodontist to re-measure and to send a letter that explains the health problem, not just the score.
• Add letters from the pediatrician, dentist, speech therapist, or oral surgeon if they have seen chewing, speech, pain, or tissue damage.
• Request copies of the reviewer’s scoring so you can see where the numbers differ.
• Ask about a new evaluation in six to twelve months if your child’s bite is still changing.

A free legal aid office in your area may help with fair hearings. Dial 211 to find one.

CHIP and other public coverage

Children whose family income is too high for Medicaid may be in CHIP, the Children’s Health Insurance Program. In states where CHIP is part of Medicaid, the same EPSDT orthodontic rules apply. In states with a separate CHIP program, orthodontic coverage depends on that program’s benefit package, and some cover braces only for severe cases. Ask your CHIP plan for its written orthodontic policy.

Children with a cleft lip or palate or another craniofacial condition may also get help through their state’s program for children with special health care needs, often run by the state health department. Hospital cleft teams can explain how orthodontics fits into that care.

Marketplace dental plans for children are another route, but HealthCare.gov notes dental coverage works differently from health coverage, and orthodontics for children is typically limited to medically necessary cases.

Lower-cost orthodontic care outside Medicaid

If Medicaid says no, or you are an adult, these are the most practical places to look:

• University orthodontic programs. Residents in accredited orthodontic programs treat patients under faculty supervision, often for less than private offices. Search the ADA’s Commission on Dental Accreditation program finder for advanced orthodontics programs near you. Expect longer appointments and a waiting list.
• Community health centers. Some federally funded health centers have dental clinics with sliding-fee scales. Most do not offer braces, but they can handle checkups and referrals. Use HRSA’s Find a Health Center tool.
• Charity programs for kids. National nonprofits match children with volunteer orthodontists for reduced fees. Our guide to free braces for low-income families compares them.
• Payment plans. Many orthodontists spread the fee over the length of treatment with no interest. Ask before you sign anything with a third-party lender.
• Tax-advantaged accounts. Braces to correct a dental problem can count as a medical expense under IRS Publication 502, so FSA or HSA money can usually be used.

The National Institute of Dental and Craniofacial Research keeps a list of other ways to find low-cost dental care, including state dental societies and clinical trials.

Common mistakes that slow approval

• Starting treatment before the decision. Medicaid generally will not pay retroactively for braces placed without approval.
• Letting coverage lapse. Missing a renewal can stop payments mid-treatment. Update your address with the state so you get renewal notices.
• Using an out-of-network office. If your child is in a managed care plan, the orthodontist must be in that plan’s network.
• Waiting too long with an older teen. Age-21 cutoffs are strict in many states.
• Missing the appeal window. The 60-day plan appeal clock starts on the date of the notice, not the day you open it.
• Skipping hygiene visits. Some plans ask for proof of good oral hygiene before they approve, since braces on unhealthy teeth can cause harm.
