About coding meningococcal conjunctivitis nos
The ICD-10-CM code for meningococcal conjunctivitis nos is A39.89 (Other meningococcal infections).
Within A39.8, choose A39.89 (Other meningococcal infections) only when documentation doesn't support a more specific option: meningococcal encephalitis (A39.81), meningococcal retrobulbar neuritis (A39.82), meningococcal arthritis (A39.83) and Postmeningococcal arthritis (A39.84).
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 870 (Septicemia or Severe Sepsis with MV >96 Hours, relative weight 6.9408), DRG 871 (Septicemia or Severe Sepsis without MV >96 Hours with MCC, relative weight 1.932) and DRG 872 (Septicemia or Severe Sepsis without MV >96 Hours without MCC, relative weight 1.0066), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
