Insulin prescription, CDL, and HIPAA

Hello everyone, this has probably been asked, but I couldnt find it when I searched the forum. I drive a tractor trailer and was just diagnosed w/ 1.5, and they want me to inject insulin. Technically I cant drive if I inject unless I apply for a federal waiver. The amounts they want me to inject are extremely small, and I think I can transfer to a non-driving job in 6-8 months…my question is, will they know if I’m getting insulin through our insurance provider, or is that protected by hipaa laws? Anyone out there know? Thanks for any info, Jake
