WOONSOCKET, R.I., Oct. 9, 2013 /PRNewswire/ -- Expanding to its 27 th state, MinuteClinic, a division of CVS Caremark Corporation and the largest provider of retail medical clinics in the United States, has opened its first locations in Louisiana inside select CVS/pharmacy stores in Baton Rouge, Mandeville, Slidell and Thibodaux. Four additional clinics will open later the month in Kenner, Metairie, New Orleans and Prairieville. The walk-in medical clinics are open seven days a week with no appointment necessary. Most major health insurance is accepted. For patients paying cash or credit, treatment prices are posted at each clinic and on www.minuteclinic.com. The cost for most services starts at $79. The Joint Commission accredits the clinics. MinuteClinic's entry into Louisiana is part of its national expansion plan to open 150 clinics nationwide in 2013. "We face a significant shortage in primary care providers, an aging Baby Boomer population and soon the addition of millions of newly insured patients through the Affordable Care Act," said Andrew Sussman, M.D., MinuteClinic President and CVS Caremark Senior Vice President/Associate Chief Medical Officer. "By increasing access to high quality, affordable care at convenient clinic locations where patients shop, MinuteClinic can help support the primary care medical home in Louisiana." More than half of MinuteClinic visits occur on evenings, weekends and holidays, according to Sussman. The clinics are staffed by MinuteClinic nurse practitioners who specialize in family health care and can diagnose, treat and write prescriptions for common family illnesses such as strep throat and ear, eye, sinus, bladder and bronchial infections. Minor wounds, abrasions, skin conditions and joint sprains are treated, and common vaccinations such as influenza, tetanus, pneumonia and hepatitis A & B are available. Walk-in camp, sports, and college physicals are available daily.
