Clinical notes
Code first
This code represents a manifestation of an underlying disease. Coding convention requires the underlying (etiology) code to be sequenced first, with this code listed second.
Excludes1 (not coded here)
An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).
- candidal meningitis (B37.5)
- coccidioidomycosis meningitis (B38.4)
- cryptococcal meningitis (B45.1)
- herpesviral [herpes simplex] meningitis (B00.3)
- infectious mononucleosis complicated by meningitis (B27.- with fifth character 2)
- measles complicated by meningitis (B05.1)
- meningoencephalitis and meningomyelitis in other infectious and parasitic diseases classified elsewhere (G05)
- mumps meningitis (B26.1)
- rubella meningitis (B06.02)
- varicella [chickenpox] meningitis (B01.0)
- zoster meningitis (B02.1)
Documentation support
General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.
- •Confirm the excluded condition(s) listed above are not also present — Excludes1 conditions cannot be coded together with this one.
- •This code represents a manifestation. Documentation should identify the underlying condition, which must be coded first.
- •As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
