About coding choroid plexus cyst
The ICD-10-CM code for choroid plexus cyst is G93.0 (Cerebral cysts). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on G93.0.
Within G93 (other disorders of brain), G93.0 is specifically for cerebral cysts. Related codes cover Anoxic brain damage, not elsewhere classified (G93.1), benign intracranial hypertension (G93.2), 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 G93.0 together with the conditions in its Excludes1 note: acquired periventricular cysts of newborn (P91.1) and congenital cerebral cysts (Q04.6).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
