1. What is the Medicare 90 Day Global Period?

The Medicare 90 Day Global Period is a postoperative period during which all related services are included in the global surgical package payment. This period begins the day of surgery and extends for 90 days, covering all necessary follow-up care related to the procedure.

2. How Does the Calculator Work?

The calculator uses a simple date calculation:

End Date = Surgery Date + 90 days

Where:

Surgery Date — The date when the surgical procedure was performed
End Date — The final day of the 90-day global period

Explanation: The calculator adds exactly 90 days to the surgery date to determine when the global period ends.

3. Importance of the 90-Day Global Period
