Time units for attendance at delivery by an anaesthesiologist, calculated on the basis of 4 base units and 1 unit for each 15-minute interval (or part thereof) of constant attendance.

When to Use

Use E100C when you are required to be in constant attendance for a vaginal delivery, such as for a patient with high-risk cardiac disease or severe pre-eclampsia.
Bill E100C for the time spent managing a patient during a trial of labour after caesarean section (TOLAC) if your presence is required for the duration of the delivery.

Common Pitfalls

Billing E100C for routine epidural maintenance without constant attendance at the actual delivery, which is restricted to P016C only.
Attempting to claim anaesthesia extra units (e.g., E009C or E010C) alongside E100C, which will result in an automatic rejection.
Failing to document precise start and stop times in the chart, which is a mandatory requirement for audit compliance regarding the 15-minute interval units.

Billing Tips

Always pair E100C with P016C when providing continuous epidural maintenance to maximize the total unit value for the obstetrical encounter.
Ensure that after-hours premiums (E400C or E401C) are applied to the total unit value of E100C if the delivery occurs outside of standard daytime hours.
