About coding blood typing test
The ICD-10-CM code for blood typing test is Z01.83 (Encounter for blood typing). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z01.83.
Within Z01.8 (encounter for other specified special examinations), Z01.83 is specifically for encounter for blood typing. Related codes cover preprocedural examinations (Z01.81), allergy testing (Z01.82), antibody response examination (Z01.84) and other specified special examinations (Z01.89).
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.
