About G93.8

G93.8 is the ICD-10-CM diagnosis code for other specified disorders of brain. 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 a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within G93, choose G93.8 (Other specified disorders of brain) only when documentation doesn't support a more specific option: cerebral cysts (G93.0), 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) and 1 more.

To report this condition, pick the subcode that matches the documentation: G93.81 (sclerosis), G93.82 (death) and G93.89 (brain).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
