The short answer is that Medicaid can pay for braces, but the question it asks is not “are these teeth crooked.” It is “is this malocclusion handicapping.” Cosmetic orthodontia is excluded in every state. Functionally handicapping malocclusion is a different case entirely, and states have built a numeric test to tell them apart.
That test is why two children in the same waiting room can get opposite answers. One scores above the state’s cutoff and gets a fully paid course of treatment. The other scores two points below and pays cash.
Why There Is a Score at All
Orthodontia sits in the optional Medicaid benefit column for adults and inside the mandatory EPSDT benefit for anyone under 21. EPSDT requires states to cover services that are medically necessary to correct or ameliorate a condition found during a screening, whether or not the state covers that service for adults. Federal regulation at 42 CFR 441.56(c) makes the same point, requiring specified diagnosis and treatment “even if the services are not included in the plan.”
That creates an obvious problem for a state Medicaid agency. “Medically necessary orthodontia” has no bright line, and the agency needs a defensible, repeatable way to separate a health problem from an aesthetic preference. Most states adopted a version of the Handicapping Labio-Lingual Deviation index, usually called the HLD index and sometimes credited to Salzmann’s occlusal index work, which converts a physical exam into points.
The index is deliberately not a diagnosis of malocclusion. California’s own scoring instructions say the intent is “to measure the presence or absence, and the degree, of the handicap caused by the components of the Index, and not to diagnose ‘malocclusion.’”
How the HLD Index Works
An orthodontist examines the patient in centric occlusion with a Boley gauge (or a millimeter ruler), measures a fixed list of conditions, and records a score for each. Absent conditions are scored zero. Some measurements are multiplied: California weights mandibular protrusion and anterior crowding by five, open bite by four, and ectopic eruption by three.
The measured items are consistent across states, with variations in weighting:
- Overjet in millimeters
- Overbite in millimeters
- Mandibular protrusion, meaning reverse overjet
- Open bite in millimeters
- Ectopic eruption, counted per tooth excluding third molars
- Anterior crowding, scored per arch
- Labio-lingual spread, meaning anterior spacing
- Posterior unilateral crossbite
Texas adds two mechanical adjustments worth understanding, because they eat points fast. Overjet is scored as the measurement minus 2 mm, since a 2 mm deviation is treated as normal. Overbite is scored as the measurement minus 3 mm. Texas also caps anterior crowding at 10 points across both arches combined, and both Texas and California prohibit scoring ectopic eruption and crowding on the same arch.
Named state cutoff scores
These come from the state agencies’ own documents, not from summaries of them.
Texas. The Texas Medicaid and CSHCN Services Program HLD Index Score Sheet, form F00143, revised August 1, 2021 and effective September 1, 2021, states that the client must have “a minimum of 26 points on the HLD index to qualify for any orthodontic care other than crossbite correction.” Cleft palate scores 15 points and severe traumatic deviations score 15. Half-mouth cases cannot be approved.
California. The Medi-Cal Dental HLD Index California Modification score sheet, form DC016 (revision 09/18), sets six automatic qualifying conditions and then states that “the remaining conditions must score 26 or more to qualify.”
Washington. The Apple Health (Medicaid) Orthodontic Services Billing Guide covers “severe malocclusions with a Washington Modified Handicapping Labiolingual Deviation (HLD) Index Score of 25 or higher” where the patient has established caries and plaque control, and HCA determines the final score from the documentation the provider submits. Washington also reviews other malocclusions case by case with prior authorization.
Two useful patterns: 26 is the most common threshold nationally, and a state one point lower is not a rounding error, it is a deliberate policy decision that changes who qualifies.
Conditions That Qualify Without Scoring
Some conditions are severe enough that the index is skipped. California’s score sheet lists six automatic qualifiers and instructs the examiner to mark an X and score no further:
- Cleft palate deformity, documented by diagnostic casts, an intraoral photograph of the palate, or a written report from a qualified specialist or craniofacial panel
- Craniofacial anomaly, with a description attached from a credentialed specialist
- Deep impinging overbite where lower incisors are destroying the soft tissue of the palate, with tissue laceration or clinical attachment loss present
- Crossbite of individual anterior teeth where clinical attachment loss and gingival recession are present
- Severe traumatic deviation, for example loss of a premaxilla segment from burns, accident, osteomyelitis or other gross pathology
- Overjet greater than 9 mm with incompetent lips, or reverse overjet greater than 3.5 mm with masticatory and speech difficulties
Washington covers a parallel list of craniofacial diagnoses outright, including cleft lip and palate, hemifacial microsomia, craniosynostosis syndromes, cleidocranial dental dysplasia, arthrogryposis, Marfan syndrome, Treacher Collins syndrome, ectodermal dysplasia and achondroplasia, with treatment performed by an HCA-recognized craniofacial team or an approved orthodontic specialist.
The Prior Authorization Process
Orthodontia is never a walk-in benefit. Expect this sequence:
- Find a Medicaid-enrolled orthodontist. This is the real bottleneck in many markets. Your state’s dental plan or the Insure Kids Now directory is the place to start.
- Get the records appointment. Photographs, panoramic and cephalometric films, and models or a digital scan. Some states require a pre-orthodontic certification signed by a general dentist.
- The orthodontist scores the HLD sheet and signs it. Both California and Texas require the actual form plus a Boley gauge measurement; Texas returns incomplete sheets.
- The state or its dental plan reviews and issues a determination. Washington’s guide is explicit that HCA, not the provider, determines the final HLD score from submitted documentation.
- Appeal if denied. For anyone under 21, EPSDT is the argument. California’s score sheet says so on its face: a patient without an automatic qualifying condition who does not score 26 or above “may still be eligible for these services based on Early and Periodic Screening, Diagnostic and Treatment (EPSDT) criteria necessary to correct or ameliorate the patient’s condition.”
One tactical note. Appeals that succeed tend to document function: chewing difficulty, speech, soft tissue trauma, periodontal damage. Appeals that fail tend to describe appearance.
What Braces Cost When Medicaid Says No
Two independent published price sources put private-practice comprehensive treatment in the same window. The American Dental Care Network’s January 2026 fee schedule lists code D8080, comprehensive orthodontic treatment of the adolescent dentition, at $5,000 to $6,800. The University of Pittsburgh School of Dental Medicine states that “the cost of traditional braces is about $5,500 to $6,500.”
University resident clinics are the reliable discount. The Ohio State Dental Center states that typical fees for full orthodontic treatment start at $4,172 for children, adolescents and adults, with a separate $545 records fee, and that the first retainer and all retention check appointments are included. Ohio State also accepts Traditional Medicaid and CareSource with preauthorization, which makes a school clinic worth calling even before a denial.
| Setting | Typical cash price |
|---|---|
| University orthodontic resident clinic | From $4,172 plus $545 records (Ohio State) |
| Private practice, comprehensive treatment | $5,000 to $6,800 (D8080) |
| Private practice, traditional braces | About $5,500 to $6,500 |
Regional variation is real, and a complex case with extractions or orthognathic surgery sits above every figure here. Get written quotes from two or three practices before committing, and confirm whether the quote is all-inclusive of retainers and emergency visits.
For deeper price detail see braces cost without insurance and Invisalign cost without insurance. Two follow-on costs people forget to budget: retainer cost after treatment ends and palate expander cost for a phase-one case.
If You Are Denied, Try These Routes
Charitable orthodontic programs. Several national programs place children with volunteer orthodontists at little or no cost. Our free braces programs guide covers eligibility, application fees and realistic odds for each one.
University clinics. Covered above, and worth an application even in an emergency-only dental state.
FQHC dental clinics. Federally qualified health centers charge on a sliding scale and can handle the general dentistry a case needs before orthodontics starts. See free dental clinics and free clinics with sliding scale fees.
In-house payment plans. Orthodontics is the most financeable corner of dentistry. Most practices split the fee across the treatment period after a down payment, often interest-free, which beats a medical credit card.

Braces sit inside the larger dental benefit, which is mandatory for children and optional for adults. See does Medicaid cover dental for the state-by-state adult picture, what does Medicaid cover for the full mandatory and optional benefit split, and does Medicaid cover vision for the parallel eyeglasses question. If you are checking eligibility rather than benefits, see Medicaid income limits for 2026 and Medicaid renewal.
The Bottom Line
Ask your state Medicaid agency or dental plan two questions before anything else: what is our HLD cutoff score, and which conditions qualify automatically. Then get a scored sheet from a Medicaid-enrolled orthodontist so you know where the case actually lands. If it clears the bar, treatment is typically paid in full. If it misses by a point or two and the patient is under 21, the EPSDT appeal is a real option, and the cash fallback is $4,172 to $6,800 rather than an unbounded number.
