About coding brain pressure
The ICD-10-CM code for brain pressure is G93.5 (Compression of brain). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on G93.5.
Within G93 (other disorders of brain), G93.5 is specifically for compression of brain. Related codes cover 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), cerebral edema (G93.6), Reye's syndrome (G93.7), other specified disorders of brain (G93.8) and 1 more.
Don't report G93.5 together with the conditions in its Excludes1 note: traumatic compression of brain (S06.A-).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
