February 27th, 2015
Originally, for providers to Attest EHR/Meaningful Use for the 2014 reporting period, the attestation deadline was February 28, 2015. However, to encourage providers to start attesting for the 2014 reporting year, CMS has extended the attestation deadline for eligible professionals to March 20, 2015. CMS indicates this has been done, "to allow providers extra time to submit Meaningful Use data..."
Eligible professionals that do not attest by the March 20, 2015 deadline will have a negative payment adjustment of 2% on CMS claims beginning January 1, 2016.
Note that this deadline does not apply to the Medicaid EHR Incentive Program.
