About coding brain death
The ICD-10-CM code for brain death is G93.82 (Brain death).
Within G93.8 (other specified disorders of brain), G93.82 is specifically for brain death. Related codes cover temporal sclerosis (G93.81) and other specified disorders of brain (G93.89).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 080 (Nontraumatic Stupor and Coma with MCC, relative weight 1.7472) and DRG 081 (Nontraumatic Stupor and Coma without MCC, relative weight 0.806), in MDC 01 (Diseases and Disorders of the Nervous 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.
