HCS-O - Home Care Clinical Specialist - OASIS

The Homecare Clinical Specialist – OASIS (HCS-O) certification through the Board of Medical Specialty Coding and Compliance (BMSC) is for clinicians working in home healthcare. This national specialty certification is earned by exam, and demonstrates the clinical skills and judgment required to correctly assess a patient’s condition.
