Z37.63Quintuplets, some liveborn

Z37.63 is the ICD-10-CM diagnosis code for Quintuplets, some liveborn. It belongs to category Z37 (outcome of delivery), 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 Z37.6 (other multiple births, some liveborn), Z37.63 is specifically for Quintuplets, some liveborn. Related codes cover multiple births, unspecified, some liveborn (Z37.60), Triplets, some liveborn (Z37.61), Quadruplets, some liveborn (Z37.62), Sextuplets, some liveborn (Z37.64) and other multiple births, some liveborn (Z37.69).

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 768 (Vaginal Delivery with O.R. Procedures Except Sterilization and/or D&C, relative weight 1.0511), DRG 796 (Vaginal Delivery with Sterilization and/or D&C with MCC, relative weight 1.181), DRG 797 (Vaginal Delivery with Sterilization and/or D&C with CC, relative weight 0.9807), DRG 798 (Vaginal Delivery with Sterilization and/or D&C without CC/MCC, relative weight 0.925), DRG 805 (Vaginal Delivery without Sterilization or D&C with MCC, relative weight 1.1273), DRG 806 (Vaginal Delivery without Sterilization or D&C with CC, relative weight 0.7892) and 2 more, in MDC 14 (Pregnancy, Childbirth and the Puerperium) and 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 treats this as a maternity diagnosis, expected only for patients age 9 through 64.

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 V27.6 (outcome of delivery, other multiple birth, some liveborn).
