Yes. This clinic trains patients for peritoneal dialysis. Training is a series of visits rather than a permanent move, and your nephrologist has to agree it suits you.
Not according to Medicare's records. Shift times change and are published nowhere, so it is still worth asking when you call.
18 stations, meaning up to 18 people can be treated at once. A larger unit usually means more shift options. It says nothing about the quality of care.
Yes. Medicare places this clinic in the bottom 34% of US clinics. That is a position in a national distribution, not a score it passed or failed — most clinics sit in the middle band by design.
It is a nonprofit facility, Medicare-certified since 2000.
By calling. Chair availability, insurance acceptance and wait times are not published by Medicare, or by anyone else, for any clinic in the country. That is why the phone number is at the top of this page.
Every measure Medicare publishes about a dialysis facility, grouped in Medicare's nine categories and numbered for citation. Nothing here is selected. Where this clinic has no figure, the cell carries a dash and Medicare's code, and the codes are explained below the table.

These two do not add up to 100%. Some patients use a graft or another form of access. Access type depends on a patient's own veins, whether earlier attempts held, how soon surgery was available, and what the patient chose.
This facility is one of 127 New York clinics rated as expected. The state has 262.

This facility is one of 294 New York clinics rated as expected. The state has 313. Based on 185 discharges.
