About O75.0

O75.0 is the ICD-10-CM diagnosis code for maternal distress during 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 (other complications of labor and delivery, not elsewhere classified), O75.0 is specifically for maternal distress during labor and delivery. Related codes cover shock during or following labor and delivery (O75.1), pyrexia during labor, not elsewhere classified (O75.2), other infection during labor (O75.3), other complications of obstetric surgery and procedures (O75.4), delayed delivery after artificial rupture of membranes (O75.5), other specified complications of labor and delivery (O75.8) and complication of labor and delivery, unspecified (O75.9).

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 669.01 (maternal distress complicating labor and delivery, delivered, with or without mention of antepartum condition), 669.02 (maternal distress complicating labor and delivery, delivered, with mention of postpartum complication) and 669.04 (maternal distress complicating labor and delivery, postpartum condition or complication).
