Covington is the seat of St. Tammany Parish and the Northshore's primary healthcare hub, with a population of approximately 11,000. While smaller than neighboring Mandeville and Slidell, Covington punches above its weight as a medical destination — St. Tammany Health System and Lakeview Regional Medical Center are both located in or near Covington, making it the center of gravity for healthcare on the north shore of Lake Pontchartrain.
The city has a charming historic downtown, a growing professional and creative community, and strong ties to the broader New Orleans metropolitan economy. For health insurance, Covington residents use healthcare.gov with their St. Tammany Parish zip code and benefit from Louisiana's 2016 Medicaid expansion.
Covington's concentration of hospital and specialist facilities makes it unusual for a city its size. St. Tammany Health System operates a full-service hospital with emergency, surgical, cardiac, cancer, and rehabilitation services. Lakeview Regional Medical Center, also in the Covington area, provides additional hospital capacity. The presence of two hospital systems in close proximity creates competition that generally benefits patients through better access and more provider choices.
For ACA marketplace enrollees, the key question is which hospitals and specialists are in-network with your chosen plan. Ambetter's network in St. Tammany Parish typically includes both major hospital systems, but confirm your specific plan's provider directory before enrolling.
