G93.49

What This Code Means

This code describes inflammation or dysfunction of the brain that doesn't fit into other specific encephalopathy categories. It's used when a patient has brain swelling or brain dysfunction from various causes that aren't more precisely defined.

Coding Tips

• •Always review the clinical documentation to identify the underlying cause of encephalopathy (toxic, metabolic, anoxic, etc.) as more specific codes may be available and preferred
• •This is a catch-all code, so ensure no more specific G93.4x subcategory applies before assigning G93.49; check for documented etiology that might support a more specific diagnosis code
