ICD-10 code for salmonella meningitis

The ICD-10-CM code for salmonella meningitis is A02.21 (Salmonella meningitis).

Within A02.2 (localized salmonella infections), A02.21 is specifically for salmonella meningitis. Related codes cover localized salmonella infection, unspecified (A02.20), salmonella pneumonia (A02.22), salmonella arthritis (A02.23), salmonella osteomyelitis (A02.24), salmonella pyelonephritis (A02.25) and salmonella with other localized infection (A02.29).

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator, relative weight 5.7444), DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC, relative weight 3.9708), DRG 094 (Bacterial and Tuberculous Infections of Nervous System with MCC, relative weight 3.4124), DRG 095 (Bacterial and Tuberculous Infections of Nervous System with CC, relative weight 2.3492), DRG 096 (Bacterial and Tuberculous Infections of Nervous System without CC/MCC, relative weight 2.3213), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506) and 2 more, in MDC 01 (Diseases and Disorders of the Nervous System) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
