About coding outcome of delivery

The ICD-10-CM code for outcome of delivery is Z37.9 (Outcome of delivery, unspecified). The official index lists 21 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z37.9.

Within Z37, choose Z37.9 (unspecified) only when documentation doesn't support a more specific option: single live birth (Z37.0), single stillbirth (Z37.1), twins, both liveborn (Z37.2), twins, one liveborn and one stillborn (Z37.3), twins, both stillborn (Z37.4), other multiple births, all liveborn (Z37.5), other multiple births, some liveborn (Z37.6) and other multiple births, all stillborn (Z37.7).

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.
