Wiki Bleph and Ptosis billing - Can we charge for cosmetic PR bleph on same eye as Ptosis?

I was looking at this website from AAO specifically.
They say in the text of the post that you cannot charge a cosmetic medically necessary bleph with a ptosis to patient responsibility, but that contradicts the beginning of the article quoting the 2017 CMS manual, so I want the AAO’s backup with an actual manual or resource from CMS confirming what their website says – makes no sense. Did the 2017 CMS manual decision change?

Hello, I am not an expert and need to read the link again. But so far, 1. The attachment with your highlighted area to me is- we cannot bill pt for the CPT as cosmetic when there is a medical necessity for CPT and we should bill the insurance for it and not the pt. 2. At our practice, ptosis and blepharopasty are bundled, we bill only for ptosis. IF blepharoplasty is a cosmetic, we bill pt for that part and ptosis repair with medical necessity goes to the insurance.
