DRG 468. This DRG represents a discharge with valid data but where the surgical
procedure is unrelated to the principal diagnosis.
Refer to 100-04, chapter 3, §20.2.1, subsection D.9. for a description of questionable
admission diagnosis codes. A/B MACs (A) may wish to consider including these
diagnoses in their data analysis.

Refer to 100-04, chapter 3, §20.2.1, subsection D.9 for a description of diagnoses which
are acceptable only when coded with a secondary diagnosis. A/B MACs (A) may wish to
include these diagnoses in their data analysis as the MCE will not reject them when they
are billed with a secondary diagnosis.
