My surgeon requires this insurance for self-pay patients. Since my insurance probably wouldn't cover follow-up surgery due to a leak or other problem, it just makes sense to protect my family from massive bills if I have a complication. Even if my surgeon didn't charge me for surgery to fix a problem, the hospital and anesthesiologist sure would.
I'm still waiting to see the costs associated with it, but I understand the basic plan is about 2000. I'm not sure if that's 30 or 60 days.
