What 59400 covers

This package represents routine care across pregnancy, vaginal birth, and the postpartum period. It includes prenatal management and a vaginal delivery, with or without episiotomy or forceps, followed by routine postpartum care. It is typically furnished by an obstetrician or another qualified maternity-care clinician in an office and hospital setting. The delivery component is for vaginal birth, not cesarean delivery.

Report 59400 when the same clinician or group furnishes all three components. The record should support the antepartum care, delivery, and postpartum services provided; when care is divided, report the applicable components rather than the complete package. CMS treats this as a maternity code, so the usual global surgery rules do not apply. If qualifying procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50% under the standard multiple procedure reduction.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
