I know she lied to get pregnancy coverage

Dear Amy: My sister-in-law has intentionally lied in order to receive Medicaid to pay for her pregnancy.

Amy Dickinson 

She has a work-from-home job making a mid-level salary, and her live-in boyfriend also works full time and contributes to the household.

I feel very disturbed that she is knowingly defrauding the system because she doesn’t want to spend her $8,000 deductible to have her baby.

I am not sure if it is wrong to report her for fraud because we are family and she trusted me when she told me she lied on her application (by saying she is no longer working).

If she found out I reported her, this would obviously create a rift in the family.

Should I just mind my own business?
