Is this a skill?

We have a 104 year old patient who was admitted s/p fall at home with C1 fx. She is done with rehab. Has NO pain. Has a surgically debrided bunion on her foot. Is a once a day dressing change enough to keep her on Med A at a skilled level.?

Why would anyone do a bunionectomy on a 104 yr old? It is not infected and she's been with us for at least 21 days. She doesn't have diabetes but does have 104 blood vessels so I could argue she has compromised lower extremity circulation. Both the podiatrist who did the bunionectomy and the PCP say she HAS to stay at the nursing home and HAS to be skilled. Neither one of them probably knows as much about Medicare regs as we do. Thanks for your help.
