Z31.441Encounter for testing of male partner of patient with recurrent pregnancy loss

Z31.441 is the ICD-10-CM diagnosis code for encounter for testing of male partner of patient with recurrent pregnancy loss. It belongs to category Z31 (encounter for procreative management), block Z30-Z39 (persons encountering health services in circumstances related to reproduction) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z31.44 (encounter for genetic testing of male for procreative management), Z31.441 is specifically for encounter for testing of male partner of patient with recurrent pregnancy loss. Related codes cover of male for testing for genetic disease carrier status for procreative management (Z31.440) and for other genetic testing of male for procreative management (Z31.448).

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.

The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It is on the CMS list of diagnoses consistent only with male patients (the sex-conflict edit itself was retired in FY2025).

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as V26.35 (encounter for testing of male partner of female with recurrent pregnancy loss).
