Welcome to Mercy Health Alliance.

Mercy Health Alliance is the exclusive network provider for Boeing’s innovative new health plan option in St. Louis called the Preferred Partnership. It offers lower paycheck contributions and, for employees in certain plans, higher Boeing contributions to the Health Savings Account. Plus, employees will pay less for office visits to a primary care physician and for generic medications.

Mercy Health Alliance providers include the Mercy Network and additional partners, including Anderson Hospital in Maryville, Ill. You get convenient access to more than 950 physicians and care teams in 176 locations in greater St. Louis, offering more personal support, more coordinated care and an enhanced level of service – all at a more affordable cost.

The Mercy Health Alliance makes it easy for you to get the care you need, when you need it. No matter which Mercy hospital, urgent care center or clinic you visit, your care team will have full access to all of your most up-to-date medical information, thanks to our powerful electronic health record. And outside the Mercy footprint, Mercy network partners like Anderson Hospital in Maryville, Ill., provide excellent care to make sure you’re covered.

Boeing employees who choose a Mercy Clinic physician can access that same information – test results, upcoming appointments and communication with your physicians – on MyMercy, our secure patient portal.
