About Us


Health Decisions, Inc. is a privately owned, Michigan Corporation founded in 1985. The firm specializes in post payment and enrollment data auditing services to group health benefit clients throughout the country.

The firm’s founders, Si Nahra and Judy Mardigian, understood early on that effective administration of group health benefits requires: the intelligent use of highly advanced and constantly changing technology; a comprehensive understanding of the forces that affect health care; and the willingness to focus accurately on the difficult-to-document eligibility information that has major financial implications.

Since 1985, Health Decisions, Inc. has successfully served hundreds of clients, including self-funded employers, HMOs, insurers including Blue Cross/Shield plans, and TPAs.

The firm successfully processes annually more than one billion dollars of paid claims data submitted in dozens of different formats; and also processes special surveys for over one quarter-million covered members.

Health Decisions, Inc. distinguishes itself with its service philosophy:

  • Respect for existing procedures;
  • Emphasis on customization; and
  • Focus on solutions.

The company is organized into three divisions along service lines and employs an extensive staff of benefit review specialists, system programmers and maintenance staff, data managers, and claim collection staff.
