Final answer:
Not all Managed Care Organizations (MCOs) are required by law to be accredited by the National Committee for Quality Assurance (NCQA), as requirements can vary, but NCQA accreditation is a voluntary standard that many MCOs adopt.
Step-by-step explanation:
The statement that All MCOs are now required to be accredited by the National Committee for Quality Assurance (NCQA) is not universally true.
While NCQA accreditation is a well-regarded standard in the industry, it is not a legal requirement for all Managed Care Organizations (MCOs) to be accredited by the NCQA. The requirement for accreditation can vary by state and by the contracts an MCO has, particularly with government programs like Medicaid or Medicare. However, many MCOs do seek NCQA accreditation voluntarily because it is a mark of quality that may distinguish them in the marketplace and can improve their operational processes.
