About coding spontaneous delivery
The ICD-10-CM code for spontaneous delivery is O80 (Encounter for full-term uncomplicated delivery).
Use an additional code to indicate outcome of delivery (Z37.0).
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.
