Final answer:
An ambulatory surgery center with Joint Commission accreditation and deemed status does not need separate CMS certification, as it meets equivalent standards.
Step-by-step explanation:
An ambulatory surgery center that has received accreditation and deemed status from the Joint Commission is considered to have met the conditions equivalent to the Centers for Medicare & Medicaid Services (CMS) certification standards. Therefore, the answer is A: Does not need to undergo the CMS certification process. By obtaining deemed status, the facility can participate in the Medicare and Medicaid programs without separate CMS certification because the Joint Commission surveys serve as a substitute for CMS inspections.
