Deduct Medicare premiums as a business expense if self-employed?

I am a self-employed sole proprietor with no employees and enrolled in Medicare last year.  I have seen conflicting information as to whether Medicare premiums can be taken as a business expense, or must rather be taken as part of the self-employed health insurance deduction.  If Medicare premiums can be taken as a business expense, where on Schedule C would they be entered?  Line 15 is out, since the line itself states "Insurance (other than health)," and the IRS instructions for line 14 state "Do not include on line 14 any contributions you made on your behalf as a self-employed person to an accident and health plan. However, you may be able to deduct on Schedule 1 (Form 1040), line 17, the amount you paid for health insurance...."  So how can Medicare premiums be taken on Schedule C?
