About coding procreative test
The ICD-10-CM code for procreative test is Z31.49 (Encounter for other procreative investigation and testing). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z31.49.
Within Z31.4, choose Z31.49 (Encounter for other procreative investigation and testing) only when documentation doesn't support a more specific option: encounter for fertility testing (Z31.41), aftercare following sterilization reversal (Z31.42), encounter for genetic testing of female for procreative management (Z31.43) and encounter for genetic testing of male for procreative management (Z31.44).
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.
