The federal meaningful-use program has, at last estimate, garnered the participation of 4,500 radiology professionals, and incentive payments of nearly $1.5 billion are still on the table for eligible diagnostic-imaging professionals. Groups that begin the attestation process by October 3, 2013, of this year can receive up to $39,000 per eligible provider, and as adoption grows among their referring-physician bases, more and more radiology practices are expected to participate as well.
