About coding eosinophilic meningitis
The ICD-10-CM code for eosinophilic meningitis is B83.2 (Angiostrongyliasis due to Parastrongylus cantonensis).
Within B83 (other helminthiases), B83.2 is specifically for angiostrongyliasis due to Parastrongylus cantonensis. Related codes cover visceral larva migrans (B83.0), Gnathostomiasis (B83.1), Syngamiasis (B83.3), internal hirudiniasis (B83.4), other specified helminthiases (B83.8) and helminthiasis, unspecified (B83.9).
The conditions in its Excludes2 note aren't part of B83.2, but may be coded alongside it if the patient has both: intestinal angiostrongyliasis (B81.3).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
