G01 — Meningitis in bacterial diseases classified elsewhere

Billable / specific codeICD-10-CM

G01 is a billable, specific ICD-10-CM code for meningitis in bacterial 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.

meningitis (in):
gonococcal (A54.81)
leptospirosis (A27.81)
listeriosis (A32.11)
Lyme disease (A69.21)
meningococcal (A39.0)
neurosyphilis (A52.13)

The underlying condition must be sequenced before this code.

Risk adjustment

G01 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

G01 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
