How to get insurance to cover a reduction?

Hello,
Most insurances do cover breast reduction surgeries, however not all plastic surgeons take insurance. This is something to ask on the first phone call to schedule your consultation.
Insurance requirements for coverage are first and foremost that this is a medical necessity which is causing you functional limitations and not for cosmetic reasons. They usually want to see longer than 6 months of shoulder grooving from bras, back/shoulder/neck pain for which OTC medications, physical therapy, supportive garments have not worked. Also, rashes under the large breast or infections warrant medical necessity.
Additionally, you or your physician can calculate your Body Surface Area based on your height and weight. This is then used to find the amount (weight) of breast tissue required by insurance to be taken off, called the Schnur Scale. You can find these calculators online. If your surgeon believes you have that much tissue to be removed, it is usually covered without issue.
However, make sure you get the insurance approval in writing as they frequently approve things verbally with no record and then rescind coverage later, sometimes after the surgery, leaving the patient with a large bill.
Good luck!

Health insurance does not cover cosmetic breast reduction, but plans usually cover breast reduction surgery that is medically necessary. In your case, you might actually be eligible in your own country. Insurance companies tend to not cover surgeries overseas.

In the absence of pictures but based on your description, it definitely sounds like you would be covered by your insurance. Different insurance companies will have different requirements but the average that most companies require to remove to qualify is approximately 500g. If you truly have an H cup bra there should be no issue getting well above that amount.
