ICD10 code of Anti-NMDA Receptor Encephalitis and ICD9 code

Anti-NMDA receptor encephalitis is a rare autoimmune disorder affecting the brain. The ICD-10 code for this condition is G04.81. This code falls under the category of "Other encephalitis and encephalomyelitis" in the ICD-10 coding system. It specifically identifies the involvement of the NMDA receptor in the inflammatory process.

In the previous ICD-9 coding system, there was no specific code for anti-NMDA receptor encephalitis. However, it could have been categorized under other forms of encephalitis, such as viral encephalitis (ICD-9 code 323.9) or autoimmune encephalitis (ICD-9 code 323.81), depending on the clinical presentation.

It is important to note that the ICD-10 coding system provides a more detailed and specific classification of diseases compared to the previous ICD-9 system. This allows for improved accuracy in coding and better tracking of disease prevalence and outcomes.
