SHERIDAN, WYOMING – April 14, 2026 – Mercy, one of the largest health systems in the United States, operates 44 acute care and specialty hospitals and more than 700 physician and outpatient clinics across Arkansas, Kansas, Missouri, and Oklahoma. Serving communities for 185 years, the system has strengthened its digital access tools, giving patients the ability to schedule visits, view test results, and communicate with caregivers directly from their phones. For the millions of people in Mercy's four-state footprint, that shift is changing how they get — and manage — everyday healthcare. Recent clinical breakthroughs and continued infrastructure investments signal that the system is focused on both near-term access and longer-term innovation.
A Health System Built for the Mid-South and Midwest
Mercy's footprint spans four states — Arkansas, Kansas, Missouri, and Oklahoma — where its 44 hospitals and more than 700 clinics serve a broad mix of urban and rural communities. The system covers a wide range of specialties, including family medicine, internal medicine, OB/GYN, pediatrics, and cardiology. Founded over 185 years ago, Mercy has grown from a regional health ministry into one of the country's largest integrated health systems, with its headquarters in Chesterfield, Missouri.
MyMercy: One App to Manage Your Care
Central to Mercy's push toward simpler access is the MyMercy platform, available as both a web portal and a downloadable smartphone app. Patients can use it to schedule video or in-office appointments, review lab and test results, message care teams, and pay bills — all without a phone call. A "First Available Scheduling" feature surfaces the earliest open slots across nearby providers. For urgent needs, a "Hold My Place" option lets patients reserve a spot in urgent or convenient care waiting rooms before leaving home, reducing time spent waiting in person.
Walk-in orthopedic care is available for sports injuries, with Mercy offering same-day access for patients who need evaluation and treatment without a full emergency room visit. The system also offers a free downloadable guide for patients exploring long-term weight-loss solutions, as well as free parenting guides covering care for children from newborns to tweens — resources accessible directly through the platform.
Why It Matters
Access to healthcare across mid-American states can be uneven, especially in smaller cities and rural areas where specialist availability is limited and appointment waits can stretch for weeks. A system with Mercy's geographic reach — combining hospital-level care with hundreds of outpatient clinics — can meaningfully bridge that gap for patients who might otherwise delay treatment. The MyMercy app and digital scheduling tools lower practical barriers: eliminating hold times, enabling remote video visits, and letting patients manage billing and results in one place. For families, seniors, and working adults across the region, a single integrated platform for health management is a genuine convenience upgrade with real health implications.
Recent Developments
Mercy has been active on multiple fronts in early 2026. In April, the system announced continued investments in patient care at its Fort Smith location. In late March, Mercy St. Louis attracted attention for deploying advanced technology to destroy liver tumors without surgery — a development reflecting the system's clinical ambitions. Earlier in March, Mercy confirmed its medical team for the 2026 St. Louis Cardinals season, continuing a long-standing partnership with the professional sports organization.
Mercy's combination of deep regional roots and expanding digital tools positions it as a primary healthcare resource for patients across the central United States for years ahead.
