Cobuzzi, MBA, CPC, CENTC, CPCH, CPCP, CPC-I, CHCC, president of CRN Healthcare Solutions, a consulting firm in Tinton Falls, N.J. "Only one state -- and it is the state government -- Hawaii is requiring coding certification, not billing, when dealing with government claims, and this is not a CMS requirement."
