G92.8
BillableOther toxic encephalopathy
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes brain inflammation and dysfunction caused by exposure to toxic substances other than those specifically listed in ICD-10-CM coding guidelines. It represents poisoning or chemical exposure that has affected the brain and nervous system.
Coding Tips
- •Always identify and document the specific toxic substance causing the encephalopathy, as this may require an additional code from the T36-T65 range for poisoning or adverse effects
- •Ensure the toxic exposure is clearly documented in the medical record and distinguish this from other causes of encephalopathy such as infectious, metabolic, or hypoxic causes
