NOTE: Neither the adjudicating component, nor the review component, is responsible for
determining whether the PIA, MOE, or disability freeze is actually affected; nor is this a factor in determining whether an onset date documentation
deficiency exists. Onset date documentation deficiencies are based only on the potential
impact of adjudicating components not following existing policy/procedure applicable
to them. However, if the missing documentation involves establishing the correct day
of the month, as opposed to establishing the correct month and/or year of onset, there
is no potential impact on the period of disability, and no substantive deficiency
exists, unless the first day of the month is involved.
