 You know, there are guidelines and things, but we assess the patient's needs. And a lot of times we can fill out an application for the patient and send it to the foundation. And a lot of times they can help pay for that initial office visit cost for the referrals. So that's been a huge help to our patients. So we're so thankful for that relationship with the foundation at the hospital as well. So we just have lots of different avenues that we try to go down to help our patients and get them what they need.
