About coding obstetric shock
The ICD-10-CM code for obstetric shock is O75.1 (Shock during or following labor and delivery). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O75.1.
Within O75 (other complications of labor and delivery, not elsewhere classified), O75.1 is specifically for shock during or following labor and delivery. Related codes cover maternal distress during labor and delivery (O75.0), 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).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
