Who publishes HCS-O certification materials?

• A. DecisionHealth
• B. Medicare
• C. CMS
• D. American Health Information Management Association

Answer: (A)

DecisionHealth is the publisher of HCS-O certification materials. They specialize in healthcare certification prep, coding resources, and practice tests, making them the go-to source for study guides and practice materials for this exam. Medicare and CMS are government agencies that run programs and set regulations; they don’t publish certification prep materials. AHIMA focuses on HIM credentials and resources, not HCS-O materials. So DecisionHealth is the best answer because they specifically publish the HCS-O study resources candidates use to prepare.
