Providers Submitting Adjustments
10.4.1 - Providers Submitting Adjustments
(Rev. 1069, Issued: 09-29-06, Effective: 11-29-06, Implementation: 11-29-06)
Part A providers that are able to submit an adjusted or corrected claim to correct an error
or omission may continue to do so and are not required to request a reopening.
Additionally, we encourage A/B MACs (A) and (HHH) who were handling the
corrections of such errors by advising providers to submit adjusted claims to instruct
providers that submitting adjusted claims continues to be the most efficient way to
correct simple errors.
