Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (HEMORRHAGES, SUBARACHNOID), chemical irritation (chemical MENINGITIS), granulomatous conditions, neoplastic conditions (e.g., carcinomatous meningitis), and other inflammatory conditions may produce this syndrome. 322.9 is a specific code that can be used to specify a diagnosis 322.9 contains 13 index entries View the ICD-9-CM Volume 1 322.* hierarchy  Index entries containing 322.9: Arachnoiditis (acute) (adhesive) (basic) (brain) (cerebrospinal) (chiasmal) (chronic) (spinal) (see also Meningitis) 322.9 meningococcal (chronic) 036.0 syphilitic 094.2 tuberculous (see also Tuberculosis, meninges) 013.0 Effusion cerebrospinal (see also Meningitis) 322.9 vessel 348.5 meninges (see also Meningitis) 322.9 spinal (see also Meningitis) 322.9 Ependymitis (acute) (cerebral) (chronic) (granular) (see also Meningitis) 322.9 Infection, infected, infective (opportunistic) 136.9 brain (see also Encephalitis) 323.9 membranes -
