Braces are often associated with cosmetic improvements, but when covered by medical insurance, they are strictly viewed as a medical procedure. The insurance most commonly covering this treatment is Medicaid or the Children’s Health Insurance Program (CHIP). Coverage is heavily restricted by state-specific regulations and is almost exclusively limited to cases deemed medically necessary for individuals typically under the age of 21. Securing this coverage requires meeting precise criteria and navigating a specific bureaucratic process.
Defining Medical Necessity for Coverage
Medicaid programs operate under the federal mandate known as the Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit. This mandate requires states to cover necessary medical and dental services for all eligible children and adolescents up to age 21. States retain flexibility, however, in defining what constitutes a “necessary” orthodontic service within this framework.
Orthodontic treatment for purely cosmetic purposes, such as minor teeth spacing or slight crowding, is virtually never covered by public insurance programs. Coverage is reserved for severe dental conditions classified as “handicapping malocclusions” that compromise a patient’s health or function. These issues include conditions that impede eating, breathing, or speaking, or those that cause significant trauma to the soft tissues of the mouth. Qualifying functional problems include severe overjets that pose an injury risk to the front teeth or significant crossbites leading to jaw dysfunction.
Specific Qualification Requirements
To move beyond the general definition of medical necessity, a patient must meet specific clinical and demographic requirements. The most significant constraint is age, as coverage is overwhelmingly provided to children and adolescents, typically those under 21. Adult qualification is rare and generally limited to debilitating conditions like severe craniofacial deformities.
The severity of the malocclusion is measured using standardized clinical scoring tools. These are often state-adopted versions of the Handicapping Labio-Lingual Deviation (HLD) index or the Salzmann (HMAT) index. These indices assign specific point values based on measurable deviations, such as the extent of overbite, overjet, crowding, or the presence of cleft palate. For example, a state using the HLD index may require a patient to reach a minimum threshold score, such as 26 points, to be considered for treatment.
Beyond the minimum score, certain conditions are deemed “auto-qualifying,” meaning they automatically meet the necessity standard regardless of the overall point total. Required documentation includes current X-rays, detailed clinical photographs, and diagnostic models of the teeth. This collection of records is used by the state’s dental review board to objectively verify the clinical score and the presence of a handicapping condition.
Navigating the Prior Authorization Process
The first practical step is to seek a referral from a general dentist to an orthodontic specialist who accepts Medicaid or CHIP. This specialist conducts a comprehensive evaluation and gathers all necessary clinical records, including measurements for the malocclusion scoring index. The orthodontist then prepares a detailed treatment plan and a formal Prior Authorization (PA) request.
The complete file, including the PA form and all supporting documentation, is submitted to the state’s Medicaid agency or a contracted third-party administrator for review. This submission requests approval to begin treatment and commits the state to payment. Review times vary significantly, ranging from a few business days to several weeks, depending on the state’s process and whether a quarterly dental board review is required. Treatment cannot begin until the official authorization is received from the state, confirming the services are approved as medically necessary.
Options When Coverage is Limited or Denied
A denial of coverage means the state did not find the malocclusion severe enough to meet its medical necessity threshold. The patient has the right to appeal this decision, which is a formal challenge to the state’s determination. The first step is to carefully review the denial letter to understand the exact reason, such as missing documentation or a score that fell just below the required minimum.
The appeal often involves resubmitting the claim with additional clinical evidence, updated X-rays, or a letter of medical necessity from a second specialist. If the initial appeal is unsuccessful, the family is entitled to request a Fair Hearing, where an administrative law judge reviews the case. For individuals who do not qualify, such as most adults or those with purely cosmetic needs, alternative options exist. These include seeking treatment at university dental schools, which often offer reduced fees, or inquiring with private orthodontic offices about in-house financing or manageable payment plans.
