Yes, Invisalign is considered a medical expense. It falls under the category of orthodontic treatment, which is typically covered by medical insurance. Orthodontic treatments aim to correct dental misalignments and improve overall oral health. Invisalign, a popular alternative to traditional braces, uses clear aligners to gradually shift teeth into proper alignment. Many insurance plans cover a portion of the costs associated with Invisalign, but coverage can vary depending on the individual's specific insurance policy. It's advisable to check with your insurance provider to determine the extent of coverage for Invisalign.
