This DX is not the same as Meningitis

autoimmune

• How do we code "NMDA" encephalitis? : "Anti-NMDA receptor encephalitis is a disease occurring when antibodies produced by the body's own immune system attack NMDA receptors in the brain. NMDA receptors are proteins that control electrical impulses in the brain."
  • It is not an infection, it is an autoimmune disease. We only have infections or toxicity for encephalitis. I can put immunological problems-other but it fails to capture that the brain is affected then. --LKolesar 14:29, 2016 March 8 (CST)
    • How about using "other-metabolic encephalitis" as well as your immunological code?Mlagadi
      • The code you mean is "Other Metabolic Encephalopathy" That is one option, I think I will discuss this with Dr. Garland. Thanks for your thoughts on this. --LKolesar 18:06, 2016 March 8 (CST)
        • please remember to update List of Diagnoses we don't code when this discussion is done, right now there it says to code Immunological problemsTtenbergen 15:34, 2016 March 16 (CDT)

bacterial encephalitis - not applicable

• in researching encephalitis, it does appear that bacterial meningitis like pneumococcal meningitis can lead to encephalitis (although it is very rare). Our codes presently do not allow a bacterial pathogen for meningoencephalitis and we do not have a code for only encephalitis. I put two websites above if anyone is interested. Should we allow a pathogen option for meningoencephalitis in light of this?--LKolesar 14:23, 2015 September 23 (CDT)
  • encephalitis is a DX code with the proper term being meningoencephalitis. But it is not meningitis.
  • Encephalitis/meningoencephalitis is always viral or other atypical pathogen..but it is NOT bacterial or fungal. So the pathogens we have listed are adequate.
  • Meningitis however, can be bacterial, fungal or occasionally viral.
  • gram pos/neg does NOT apply to meningoenchphalitis. If you think that this is the organism causing the problem, then the underlying condition is probably Meningitis, not encephalitis. (ie: the “meningo” part of “meningoencephalitis” is confusing). Meningoencephalitis is not the same as “Meningitis”…that is a separate diagnosis.--Dr. Anand Kumar, 1330, 2016, February 29.
