Medicaid does cover braces in New York, but only for enrollees under 21 whose misalignment is severe enough to be medically necessary under the state’s scoring rules. Cosmetic straightening doesn’t qualify. Adults are almost entirely excluded, with narrow exceptions for orthodontics tied to jaw surgery or cleft palate treatment.
How New York Decides a Case Is Medically Necessary
New York uses the Handicapping Labio-Lingual Deviation (HLD) Index to measure whether a bite problem qualifies. The HLD isn’t asking whether teeth look crooked. It’s measuring whether the malocclusion creates a physical handicap that interferes with function or damages tissue.1eMedNY. Handicapping Labio-Lingual Deviation (HLD) Index Report
There are two ways to qualify. Either the case involves an auto-qualifying condition, or it scores at least 26 points on the HLD’s measurements.2New York State Department of Health (emedny.org). Evaluation for Severe Physically Handicapping Malocclusion
Auto-Qualifying Conditions
If any of these is present, the orthodontist marks the HLD form and the case qualifies without further scoring:
- Severe overjet: upper front teeth protrude more than 9mm beyond the lower teeth, with the lips unable to close comfortably
- Severe underbite: lower jaw protrudes more than 3.5mm beyond the upper teeth, causing difficulty chewing or speaking
- Deep impinging overbite: lower front teeth bite into the palate hard enough to cause tissue damage, with visible laceration or attachment loss
- Anterior crossbite with tissue damage: individual front teeth are positioned behind the lower teeth, with gum recession and attachment loss present
- Severe traumatic deviations: jaw or tooth damage from burns, accidents, or bone disease that significantly alters the dental structure
- Impacted permanent front teeth: incisors or canines trapped in bone or tissue where they won’t erupt on their own and extraction would compromise the arch
The orthodontist documents the condition with clinical findings and photographs. No point total is needed.1eMedNY. Handicapping Labio-Lingual Deviation (HLD) Index Report
The 26-Point Threshold
When no auto-qualifying condition applies, the orthodontist measures specific features and assigns points using set formulas. The case qualifies if the total reaches 26. The scored components are:
- Reverse overjet up to 3.5mm: measured in millimeters, multiplied by 5
- Open bite: measured in millimeters, multiplied by 4
- Ectopic eruption: each tooth more than 50% blocked out of the arch (excluding wisdom teeth), multiplied by 3
- Anterior crowding: 5 points for the upper arch and 5 for the lower if arch length insufficiency exceeds 3.5mm, capped at 10
- Posterior unilateral crossbite: 4 points if present, involving at least one molar and one adjacent tooth
If both ectopic eruption and anterior crowding exist in the front of the mouth, only the more severe condition is scored. Posterior ectopic teeth can be counted separately from anterior crowding.3eMedNY. Handicapping Labio-Lingual Deviation (HLD) Index Report
Cases that fall short of 26 points aren’t automatically dead. The New York Department of Health may still approve coverage based on its own professional assessment if the orthodontist documents a strong medical necessity argument.3eMedNY. Handicapping Labio-Lingual Deviation (HLD) Index Report It’s uncommon, but a borderline case with well-documented functional problems is worth pursuing.
Adults Are Almost Never Covered
New York Medicaid lists adult orthodontics as outside the scope of the program. The only exceptions are orthodontics tied to approved orthognathic (jaw) surgery or ongoing cleft palate treatment.4New York State Department of Health. New York State Medicaid Program Dental Policy and Procedure Code Manual An adult who needs braces for any other reason, however functional the problem may be, will not get them through Medicaid. That’s why the under-21 window matters so much for families who can get their children evaluated before that cutoff.
Child Health Plus Is Not a Substitute
Child Health Plus is a separate program for children who don’t qualify for Medicaid. Its orthodontic coverage is far narrower: only children with severe medical conditions such as cleft lip or cleft palate.5New York State Department of Health. Child Health Plus A child in Child Health Plus with a high HLD score but no cleft condition would not receive orthodontic coverage. If your child has a significant malocclusion and your household income is within Medicaid’s range, Medicaid is the path to braces, not Child Health Plus.
Do You Actually Qualify for Medicaid?
Orthodontic coverage only matters if the child is enrolled. New York sets income limits as a percentage of the federal poverty level, varying by age and household:
- Children ages 1 to 18: household income at or below 154% of the federal poverty level
- Young adults 19 to 20 living with parents: at or below 155% FPL
- Adults under 65: at or below 138% FPL
- Infants under 1 and pregnant women: under 223% FPL
For a family of four in 2026, the federal poverty level is $33,000, so a child in that household would qualify at family income at or below roughly $50,820.6HealthCare.gov. Federal Poverty Level (FPL)
If your income is over the limit but not by much, New York’s Excess Income (spend-down) program can still work. The amount by which your income exceeds the Medicaid level acts like a deductible. Once your medical bills in a given month reach that excess, Medicaid picks up additional costs for the rest of the month.7New York State Department of Health. Medicaid Excess Income (“Spenddown” or “Surplus Income”) Program
How the Approval Process Works
Getting braces approved isn’t a single visit. Start with a referral from a primary care doctor or general dentist. From there, a Medicaid-participating orthodontist performs a comprehensive evaluation: X-rays (including a full-mouth series and cephalometric film), diagnostic casts, and photographs. The orthodontist completes the HLD Index form, either scoring the malocclusion or documenting an auto-qualifying condition.
Where the paperwork goes depends on how you receive Medicaid. Most enrollees are in a Medicaid managed care plan, and the orthodontist submits the evaluation to that plan for review. Fee-for-service enrollees have their submission go directly to the state through eMedNY in Albany.8New York State Department of Health. Transition of Dental and Orthodontia A fee-for-service request submitted for someone actually enrolled in a managed care plan will be rejected automatically, so confirm your enrollment type before the office submits anything.
If Your Claim Is Denied
You and your orthodontist will both receive the denial and notice of your right to appeal. The strongest option in New York is a Fair Hearing through the Office of Temporary and Disability Assistance. You can request one at 1-800-342-3334.9Office of Temporary and Disability Assistance. Request Hearing – Fair Hearings An administrative law judge reviews the medical evidence and the basis for denial. Strong documentation is what wins these: a complete HLD form, clear photographs of tissue damage or functional impairment, and a written narrative from the orthodontist explaining medical necessity.
If you’re in a managed care plan, you may also pursue an external medical review, where an independent reviewer evaluates the plan’s denial. The external decision is binding on the plan.
Denials usually come down to one of three things: a score below 26 with no auto-qualifying condition, incomplete documentation, or a treatment plan that doesn’t clearly link the orthodontic problem to a functional impairment. For borderline cases, ask the orthodontist to write a detailed narrative that goes beyond the HLD form itself. That narrative often decides the appeal.
Finding an Orthodontist Who Takes Medicaid
Not every orthodontist participates in Medicaid. The New York State Provider and Health Plan Look-Up tool lets you search for providers in specific plans, including Medicaid managed care.10New York State Department of Health. NYS Provider and Health Plan Look-Up Tool Enter your managed care plan name to see in-network orthodontists. A primary care doctor or general dentist can also refer you.
When you call, confirm two things: the practice currently accepts your specific Medicaid plan, and the orthodontist is willing to complete and submit the HLD Index documentation. Some practices take Medicaid for general dentistry but not for orthodontic evaluations. If you’re in a rural area and can’t find a participating orthodontist nearby, call your managed care plan’s member services line. Plans are generally required to help members access covered services within a reasonable distance.
Protecting Coverage Once Treatment Starts
Orthodontic treatment typically lasts 18 to 30 months, and circumstances change. If your child’s Medicaid lapses briefly, they switch managed care plans, or you relocate within New York, ongoing authorized treatment is generally protected. Once a course of orthodontics has been approved and started, it should continue even after a plan switch or a move to fee-for-service Medicaid.
Missed appointments are different. Orthodontists can dismiss patients who repeatedly fail to show up or don’t follow instructions, and Medicaid won’t step in. Once dismissed, finding another Medicaid orthodontist to take over mid-treatment is hard. Keep every appointment, follow the treatment instructions, and flag scheduling conflicts early. Getting approved was the difficult part; don’t lose the coverage over missed visits.
