Z52.819Egg (Oocyte) donor, unspecified

Z52.819 is the ICD-10-CM diagnosis code for egg (Oocyte) donor, unspecified. It belongs to category Z52 (donors of organs and tissues), block Z40-Z53 (Encounters for other specific health care) 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 Z52.81, choose Z52.819 (unspecified) only when documentation doesn't support a more specific option: under age 35, anonymous recipient (Z52.810), under age 35, designated recipient (Z52.811), age 35 and over, anonymous recipient (Z52.812) and age 35 and over, designated recipient (Z52.813).

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 on the CMS list of diagnoses consistent only with female 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 V59.70 (egg (oocyte) (ovum) donor, unspecified).
