About coding echovirus meningitis
The ICD-10-CM code for echovirus meningitis is A87.0 (Enteroviral meningitis).
Within A87 (viral meningitis), A87.0 is specifically for enteroviral meningitis. Related codes cover adenoviral meningitis (A87.1), lymphocytic choriomeningitis (A87.2), other viral meningitis (A87.8) and unspecified (A87.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 075 (Viral Meningitis with CC/MCC, relative weight 1.7707) and DRG 076 (Viral Meningitis without CC/MCC, relative weight 0.8675), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
