Since some objectives or measures may not relate to your practice, many objectives and measures have exclusions available that may exempt you from completing certain criteria. If you qualify for an exclusion, you can claim the exclusion during attestation and you do not need to complete the objective / measure to achieve Meaningful Use.
There is no limit to the number of exclusions a provider can claim for Meaningful Use. If you are claiming an exclusion, make sure you have documentation that would support the exclusion and that this documentation is retained in your records for at least 6 years.
For more information, please see our article about exclusions here.
