About Z31.84

Z31.84 is the ICD-10-CM diagnosis code for encounter for fertility preservation procedure. 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 Z31.8 (encounter for other procreative management), Z31.84 is specifically for encounter for fertility preservation procedure. Related codes cover male factor infertility in female patient (Z31.81), Rh incompatibility status (Z31.82), assisted reproductive fertility procedure cycle (Z31.83) and other procreative management (Z31.89).

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.

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

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 V26.82 (encounter for fertility preservation procedure).
