About coding Pseudohydrocephalus
The ICD-10-CM code for Pseudohydrocephalus is G93.2 (Benign intracranial hypertension).
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.
Don't confuse with (Excludes1 for G93.2)
