About coding Mantoux test
The ICD-10-CM code for Mantoux test is Z11.1 (Encounter for screening for respiratory tuberculosis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z11.1.
Within Z11 (encounter for screening for infectious and parasitic diseases), Z11.1 is specifically for encounter for screening for respiratory tuberculosis. Related codes cover screening for intestinal infectious diseases (Z11.0), screening for other bacterial diseases (Z11.2), screening for infections with a predominantly sexual mode of transmission (Z11.3), screening for human immunodeficiency virus [HIV] (Z11.4), screening for other viral diseases (Z11.5), screening for other protozoal diseases and helminthiases (Z11.6), testing for latent tuberculosis infection (Z11.7), screening for other infectious and parasitic diseases (Z11.8) and 1 more.
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.
