About coding arthritis typhoid
The ICD-10-CM code for arthritis typhoid is A01.04 (Typhoid arthritis).
Within A01.0 (typhoid fever), A01.04 is specifically for typhoid arthritis. Related codes cover unspecified (A01.00), meningitis (A01.01), with heart involvement (A01.02), pneumonia (A01.03), osteomyelitis (A01.05) and with other complications (A01.09).
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 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC, relative weight 2.1859), DRG 868 (Other Infectious and Parasitic Diseases Diagnoses with CC, relative weight 1.0235) and DRG 869 (Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, relative weight 0.6787), 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.
