About coding endophthalmitis bleb
The ICD-10-CM code for endophthalmitis bleb is H59.43 (Inflammation (infection) of postprocedural bleb, stage 3).
Within H59.4 (inflammation (infection) of postprocedural bleb), H59.43 is specifically for inflammation (infection) of postprocedural bleb, stage 3. Related codes cover unspecified (H59.40), stage 1 (H59.41) and stage 2 (H59.42).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
