Code Maintenance Committee (CMC)

CDBP established its Code Maintenance Committee to ensure that all stakeholders have an active role in evaluating and voting on CDT Code changes. It is the body that votes to accept, amend or decline requests. The CMC is expected to arrive at decisions that are in the best interests of the profession and patients, and third-party payers/administrators.
