Under the Affordable Care Act, commonly known as Obamacare, essential health benefits are required to be covered by insurance plans. These essential health benefits include services related to mental health, prescription drugs, and rehabilitative and habilitative services and devices. TMJ (temporomandibular joint) disorders fall under the category of rehabilitative services, and as such, treatments for TMJ may be covered by insurance plans that comply with the ACA. However, it's important to note that coverage specifics can vary depending on the individual insurance plan, so it's advisable to review the plan's documentation or contact the insurance provider directly to confirm the coverage for TMJ treatments under Obamacare. Additionally, some states may have specific regulations regarding the coverage of TMJ treatments, so it's beneficial to check the regulations in the relevant state. Overall, while TMJ treatments may be covered under Obamacare, it's essential to verify the coverage details with the insurance provider for accurate information.
