Which MS-DRGs does A34 group to?
A34 sits in MDC 14 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

As a secondary diagnosis, A34 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
