G02

G02 — Meningitis in other infectious and parasitic diseases classified elsewhere

Billable / specific codeICD-10-CM

G02 is a billable, specific ICD-10-CM code for meningitis in other infectious and parasitic diseases classified elsewhere. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

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)

Code first

The underlying condition must be sequenced before this code.

underlying disease, such as:
African trypanosomiasis (B56.-)
poliovirus infection (A80.-)

Risk adjustment

G02 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

G02 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
