Which MS-DRGs does B00.51 group to?
B00.51 sits in MDC 02 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 124Other Disorders of the Eye with MCC or Thrombolytic Agentmedical
- 125Other Disorders of the Eye without MCCmedical
As a secondary diagnosis, B00.51 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
