ICD-10 code for proteus

The ICD-10-CM code for proteus is B96.4 (Proteus (mirabilis) (morganii) as the cause of diseases classified elsewhere).

Within B96 (other bacterial agents as the cause of diseases classified elsewhere), B96.4 is specifically for proteus (mirabilis) (morganii) as the cause of diseases classified elsewhere. Related codes cover mycoplasma pneumoniae [M. pneumoniae] as the cause of diseases classified elsewhere (B96.0), Klebsiella pneumoniae [K. pneumoniae] as the cause of diseases classified elsewhere (B96.1), escherichia coli [E. coli ] as the cause of diseases classified elsewhere (B96.2), hemophilus influenzae [H. influenzae] as the cause of diseases classified elsewhere (B96.3), pseudomonas (aeruginosa) (mallei) (pseudomallei) as the cause of diseases classified elsewhere (B96.5), Bacteroides fragilis [B. fragilis] as the cause of diseases classified elsewhere (B96.6), Clostridium perfringens [C. perfringens] as the cause of diseases classified elsewhere (B96.7) and other specified bacterial agents as the cause of diseases classified elsewhere (B96.8).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

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.
