About G93.2
G93.2 is the ICD-10-CM diagnosis code for benign intracranial hypertension. It belongs to category G93 (other disorders of brain), block G89-G99 (other disorders of the nervous system) and chapter 6 (diseases of the nervous system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within G93 (other disorders of brain), G93.2 is specifically for benign intracranial hypertension. Related codes cover cerebral cysts (G93.0), Anoxic brain damage, not elsewhere classified (G93.1), Postviral and related fatigue syndromes (G93.3), other and unspecified encephalopathy (G93.4), compression of brain (G93.5), cerebral edema (G93.6), Reye's syndrome (G93.7), other specified disorders of brain (G93.8) and 1 more.
Don't report G93.2 together with the conditions in its Excludes1 note: hypertensive encephalopathy (I67.4) and obstructive hydrocephalus (G91.1).
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 102 (Headaches with MCC, relative weight 1.1201) and DRG 103 (Headaches without MCC, relative weight 0.822), 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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 348.2 (benign intracranial hypertension).
