About coding postoperative hypotension
The ICD-10-CM code for postoperative hypotension is I95.81 (Postprocedural hypotension).
Within I95.8 (other hypotension), I95.81 is specifically for postprocedural hypotension. Related codes cover other hypotension (I95.89).
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 312 (Syncope and Collapse, relative weight 0.866), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
