About coding streptococcal acute meningitis
The ICD-10-CM code for streptococcal acute meningitis is G00.2 (Streptococcal meningitis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on G00.2.
Within G00 (bacterial meningitis, not elsewhere classified), G00.2 is specifically for streptococcal meningitis. Related codes cover hemophilus meningitis (G00.0), Pneumococcal meningitis (G00.1), staphylococcal meningitis (G00.3), other bacterial meningitis (G00.8) and bacterial meningitis, unspecified (G00.9).
Use an additional code to further identify organism (B95.0-B95.5).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
