Toxic encephalopathy (G92)
ICD-10 code G92 identifies cases of toxic encephalopathy, a brain disorder resulting from exposure to harmful substances. This section is essential for coding different types and severities of brain toxicity caused by drugs, chemicals, or metabolic disturbances.
The main code, G92, covers toxic encephalopathy broadly, while subdivisions specify particular conditions. The series from G92.0 to G92.05 define immune effector cell-associated neurotoxicity syndrome, often related to treatments like CAR T-cell therapy, graded by severity. G92.8 captures other toxic encephalopathies and includes conditions also known as toxic encephalitis or hyperammonemic encephalopathy, linked to various toxins and metabolic imbalances. Finally, G92.9 is used for unspecified toxic encephalopathy cases and includes poisoning from metals like lead, mercury, or arsenic, and exposure to substances such as carbon monoxide or organophosphates. Understanding the distinctions in these codes helps ensure precise documentation for toxic brain conditions caused by different agents.
