Here is the CMS (Centers for Medicare and Medicaid) website. http://www.cms.gov/
There are links to Medicare and to Medicare coverages. I hope this helps.

Your husband's doctor can advise you also. He/she will know how to direct you to really good quality care. People get help with catheter care and ostomy and bowel care routinely, so it won't be difficult to find someone who knows just what to do.
