I have an Anthem Blue Cross HMO (UCLA Medical Group, considered the best in the area), and a different secondary Anthem Blue Cross medical insurance through my wife's employer. This past year I had 5 different surgeries. All on different body parts. All included being admitted to the hospital. Because I have the secondary insurance, my out of pocket has been zero, although I do have a small copay for prescription medications. So, in my case, I don't currently need an HSA, although I have it avaliable.
Some, may be better off purchasing their own disability insurance, as a medical issue or accident could put them off work for some time. For example, in my case, I have been off work for medical reasons from this past May 13th and continuing until April, unless I am capable of returning sooner. Either way, I will be returning with restrictions as I will continue to heal.
So, in short, between my job, the generous benifits, and the disability insurance I pay for, my income has not skipped a beat. Considering everything I have gone through, and the potential for significant negative finincial impact, I have been very fortunate.
