Lacey Wattles

Population Health Informatics Analyst

Lacey joined Rocky Mountain Health Network in July 2015. She brings an in-depth knowledge of healthcare data, reporting and analytics to her new role. Population health has become an integral part of health care as payers are shifting to reimbursement based on quality of care rather than traditional fee-for-service. Lacey’s role for Rocky Mountain Accountable Health Network, an accountable care organization, is to facilitate and support the goal of accountable care, which is to ensure that patients, especially the chronically ill, get the right care at the right time, while avoiding unnecessary duplication of services and preventing medical errors. Using data analytic tools and reports, she works with Care Coordinators, quality team members and medical staff to reach the targeted patients.

Lacey earned her Bachelor’s degree in Business Administration-Management Information Systems from Montana State University-Billings. She is also pursuing her Registered Health Information Technician (RHIT) certification.

Lacey has worked in many different aspects of healthcare including IT, Electronic Medical Record (EMR) management, medical billing software implementations, skilled nursing facility administration, Third Party Administrator (TPA) experience, and healthcare clinic administration.

Her passion for analyzing patient data for the purpose of improving patient care while controlling costs is what drives her motivation to ensure the success of the ACO.
