I hate to be the bearer of bad news. If you need a flex sig and a biopsy chances are slim that any individual insurance company will accept you at any price, and if there is one that will they won't cover those procedures since they are pre-existing. Also, most companies will not accept someone unemployed on an individual policy. This is not because they're afraid you can't pay the premium but because they know you'll possibly soon get employment with benefits and cancel the policy. They will issue short term policies but those don't cover any pre-existing conditions.

Dental implants are not covered with health insurance, nor are they covered with most dental policies.
