Toxic and Metabolic Encephalopathy
Per Coding Clinic, Second Quarter 2024:
When a patient has both toxic encephalopathy and metabolic encephalopathy and they are due to TWO SEPARATE CAUSES, both should be coded.
Code Example:
A patient presented to the ED with complaints of lethargy and was admitted and diagnosed with sepsis due to UTI. The patient was also diagnosed with metabolic encephalopathy due to the sepsis and toxic encephalopathy secondary to pain medication that was properly administered.
Code Assignment:
Assign BOTH Codes: G93.41, Metabolic encephalopathy AND G92.8, Other toxic encephalopathy.
The Excludes2 note at subcategory G93.4, Other and unspecified encephalopathy, allows the reporting of code G93.41 with code G92.8 when appropriate.
