What Medicare Covers for Orthodontic Treatment

Medicare is the federal health insurance program for people age 65 and older, some younger people with disabilities, and people with end-stage renal disease. When it comes to dental care, including orthodontics, Medicare's coverage is quite limited. Original Medicare (Parts A and B) does not cover routine dental services, and this includes braces, aligners, or other orthodontic treatments for straightening teeth.

Orthodontics refers to dental treatment that straightens teeth or corrects bite problems. This includes traditional metal braces, ceramic braces, lingual braces (placed behind teeth), and clear aligners like Invisalign. The cost of orthodontic treatment can range from $3,000 to $8,000 or more, depending on the complexity of the case and the type of treatment chosen. For many people, this represents a significant out-of-pocket expense.

Medicare Part D, which covers prescription medications, also does not cover orthodontic services. The program's dental exclusion applies across all parts of Original Medicare. This is different from medical insurance plans offered through employers or the Affordable Care Act marketplace, many of which do include some dental coverage as part of their standard benefits.

However, there are specific situations where orthodontic care might receive some level of coverage or financial assistance. Understanding these exceptions and alternatives can help Medicare beneficiaries explore their options for managing the cost of orthodontic treatment. The distinction between what Medicare covers and what other programs or plans might cover is an important one to understand when considering orthodontic care.

Practical Takeaway: Medicare does not cover orthodontics under Original Medicare. If you need braces or aligners, you will need to explore other options such as dental discount plans, Medicaid (if you qualify), or private dental insurance to help manage costs.

Medicare Advantage Plans and Dental Coverage

Medicare Advantage Plans, also called Medicare Part C, are an alternative to Original Medicare. These plans are offered by private insurance companies approved by Medicare and must cover everything that Original Medicare covers. However, Medicare Advantage plans are allowed to offer additional benefits beyond what Original Medicare provides, and many do include dental coverage.

Approximately 42% of Medicare beneficiaries were enrolled in Medicare Advantage plans as of 2023. Of those plans, many offer some form of dental coverage, though the extent of that coverage varies widely from plan to plan. Some plans offer comprehensive dental benefits including preventive care, basic procedures, and major procedures. Others offer more limited coverage that includes only preventive services like cleanings and X-rays.

When it comes to orthodontics specifically, Medicare Advantage plans that include dental benefits may or may not cover braces or aligners. Some plans explicitly exclude orthodontics from their dental benefits. Others may cover a portion of orthodontic costs, but usually only for medically necessary orthodontic treatment rather than treatment for cosmetic reasons. Medically necessary orthodontics might include treatment for severe bite problems that affect chewing or speech, or treatment needed after jaw surgery.

If you are considering a Medicare Advantage plan or are already enrolled in one, the Summary of Benefits and Coverage document for your specific plan will outline exactly what dental services are covered, including whether orthodontics is included. You can find this information in your plan's materials or by contacting the plan directly. Plans change their benefits each year, so it is important to review your plan's current dental coverage during the annual open enrollment period (October 15 to December 7).

The cost-sharing for dental services in Medicare Advantage plans also varies. Some plans cover preventive services with no out-of-pocket cost, while you may have to pay a copay or coinsurance for major services like orthodontics. A typical copay for orthodontic treatment might range from $500 to $1,500 per year, though some plans may cover a percentage of the total cost instead.

Practical Takeaway: If you are enrolled in or considering a Medicare Advantage plan, review the specific dental benefits section of your plan documents to see whether orthodontics is covered and what your out-of-pocket costs would be. Not all Medicare Advantage plans include dental benefits, and those that do may limit or exclude orthodontic coverage.

Medicaid Coverage for Orthodontics in Medicare Beneficiaries

Medicaid is a joint federal and state program that provides health coverage to low-income individuals and families. Unlike Medicare, which is primarily age-based, Medicaid is means-tested, meaning coverage depends on income and other financial factors. Some people qualify for both Medicare and Medicaid, and these individuals are called "dual eligible" beneficiaries. There are approximately 12 million dual eligible beneficiaries in the United States.

If you are a Medicare beneficiary who also qualifies for Medicaid, your state's Medicaid program may cover some or all of the cost of orthodontic treatment, depending on your state's specific Medicaid rules. Medicaid coverage for orthodontics varies significantly from state to state. Some states cover orthodontics for children only, while others may cover it for both children and adults under certain circumstances. A few states do not cover orthodontics through Medicaid at all.

Most states that do offer orthodontic coverage through Medicaid restrict it to cases where the treatment is deemed medically necessary rather than cosmetic. Medical necessity for orthodontics is typically determined by the severity of the bite problem or misalignment. Many state Medicaid programs use criteria such as the Handicapping Malocclusion Assessment Record (HAMAR) or similar scoring systems to determine whether a patient's orthodontic condition meets the threshold for coverage.

For example, in California, Medicaid (called Medi-Cal) covers orthodontics for beneficiaries up to age 21 if the patient has a severe malocclusion that affects eating or speech. In New York, Medicaid covers orthodontic treatment when medically necessary, and this can apply to both children and adults. However, in some states like South Carolina, Medicaid does not cover orthodontics at all for any age group.

To find out whether your state's Medicaid program covers orthodontics, you can contact your state Medicaid office directly or visit your state's Medicaid website. If you think you might be able to access Medicaid as a dual eligible beneficiary, you should discuss this with a social worker or contact your state Medicaid agency to learn about the income and resource limits in your state.

Practical Takeaway: If you are a dual eligible beneficiary (receiving both Medicare and Medicaid), your state's Medicaid program may cover orthodontics, but coverage rules vary by state. Contact your state Medicaid office to understand what orthodontic services, if any, are covered in your state and what requirements must be met.

Medically Necessary Versus Cosmetic Orthodontics

An important distinction in understanding orthodontic coverage is the difference between medically necessary orthodontics and cosmetic orthodontics. This distinction often determines whether any insurance program, including Medicare Advantage or Medicaid, will cover the cost of treatment. Medically necessary orthodontics is treatment required to correct a condition that affects a person's health, function, or ability to eat or speak properly. Cosmetic orthodontics is treatment done primarily to improve appearance.

Examples of medically necessary orthodontic conditions include severe overbite or underbite that affects chewing or causes jaw pain, an open bite where the front teeth do not meet when the mouth is closed, crossbite where upper and lower teeth do not align properly, and crowding so severe that it affects oral hygiene or speech. Patients with these conditions may experience difficulty chewing, speaking clearly, or maintaining proper oral hygiene, which can lead to tooth decay and gum disease.

Cosmetic orthodontics, by contrast, refers to treatment for mild crowding, minor spacing issues, or teeth that are straight enough to function properly but are not perfectly aligned for appearance. A person who simply wants straighter teeth for cosmetic reasons, without any functional problem, would typically have cosmetic orthodontics.

Insurance programs that do cover orthodontics almost always require documentation that the treatment is medically necessary. This typically involves an examination and clinical documentation from an orthodontist or dentist showing that the malocclusion (bite problem) meets specific criteria. The criteria may include measurements of bite angles, documentation of functional problems, or other clinical findings. Some insurance programs use specific scoring systems or guidelines to make this determination.
