A federal conviction is a criminal offense that has been committed and prosecuted under federal law. A state conviction, on the other hand, is a criminal offense that has been committed and prosecuted under state law. A misdemeanor conviction is a criminal offense that is less serious than a felony and is typically punishable by a fine, probation, or a term of imprisonment of one year or less. In the context of Medicare enrollment, certain types of convictions, including felonies and misdemeanors, can disqualify an individual from enrolling or continuing to participate in the Medicare program.
