About coding cerebral anoxia
The ICD-10-CM code for cerebral anoxia is G93.1 (Anoxic brain damage, not elsewhere classified). The official index lists 8 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G93.1.
Within G93 (other disorders of brain), G93.1 is specifically for Anoxic brain damage, not elsewhere classified. Related codes cover cerebral cysts (G93.0), 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 G93.1 together with the conditions in its Excludes1 note: cerebral anoxia due to anesthesia during labor and delivery (O74.3), cerebral anoxia due to anesthesia during the puerperium (O89.2) and neonatal anoxia (P84).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
