Granted it has been many years, but I never had a problem with BC/BS paying for prescriptions, therapy and bloodwork. The key on the bloodwork was ensuring that it was coded 'correctly.'
I never looked to have them cover surgical costs, but then again, back then I was only looking at $7K.
Current insurance does not know about any of the prior issues...so they pick up the annual trek I make to the GYN without question.
