About coding carrier of typhoid
The ICD-10-CM code for carrier of typhoid is Z22.0 (Carrier of typhoid).
Within Z22 (carrier of infectious disease), Z22.0 is specifically for carrier of typhoid. Related codes cover carrier of other intestinal infectious diseases (Z22.1), carrier of diphtheria (Z22.2), carrier of other specified bacterial diseases (Z22.3), carrier of infections with a predominantly sexual mode of transmission (Z22.4), carrier of human T-lymphotropic virus type-1 [HTLV-1] infection (Z22.6), latent tuberculosis (Z22.7), carrier of other infectious diseases (Z22.8) and unspecified (Z22.9).
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 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
