After working together for many years, Wisconsin's Amery Regional Medical Center is merging operations with Bloomington-based HealthPartners.

Terms of the deal, which takes effect Wednesday, were not announced.

Amery Regional Medical Center is a nonprofit, 25-bed critical access hospital in Amery, a town of about 3,000 in northwest Wisconsin. It has four clinics, a dialysis center, geriatric inpatient care and an assisted-living facility.

It has annual revenue of about $52 million.

The merger fortifies HealthPartners' reach in northwestern Wisconsin, where it also operates in Hudson and New Richmond.

"HealthPartners has been a strong partner since 1998, so joining the family only strengthens our mission," Amery Regional Medical Center CEO Michael Karuschak Jr. said in a statement. "Working together we can improve services, control costs, access new technology and look to the future with an innovative spirit."

HealthPartners has partnered with Amery Regional Medical on a shared electronic medical record system, and many HealthPartners physicians and other clinicians work there.
