About O75.89

O75.89 is the ICD-10-CM diagnosis code for other specified complications of labor and delivery. It belongs to category O75 (other complications of labor and delivery, not elsewhere classified), block O60-O77 (complications of labor and delivery) and chapter 15 (pregnancy, childbirth and the puerperium). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within O75.8, choose O75.89 (Other specified complications of labor and delivery) only when documentation doesn't support a more specific option: maternal exhaustion complicating labor and delivery (O75.81) and onset (spontaneous) of labor after 37 completed weeks of gestation but before 39 completed weeks gestation, with delivery by (planned) cesarean section (O75.82).

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 998 (Principal Diagnosis Invalid as Discharge Diagnosis), in MDC 14 (Pregnancy, Childbirth and the Puerperium), 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 on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

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 659.81 (other specified indications for care or intervention related to labor and delivery, delivered, with or without mention of antepartum condition), 669.81 (other complications of labor and delivery, delivered, with or without mention of antepartum condition), 669.82 (other complications of labor and delivery, delivered, with mention of postpartum complication) and 1 more.
