About coding obstetric complication
The ICD-10-CM code for obstetric complication is O75.9 (Complication of labor and delivery, unspecified). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O75.9.
Within O75, choose O75.9 (Complication of labor and delivery, unspecified) only when documentation doesn't support a more specific option: maternal distress during labor and delivery (O75.0), 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) and other specified complications of labor and delivery (O75.8).
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.
