Explanation: The calculator adds the specified number of global days to the surgery date to determine when the global period ends.
Details: Correctly calculating the global period is essential for proper billing and coding. Services provided during the global period that are related to the surgery should not be billed separately.
Tips: Enter the surgery date and the number of global days for the specific procedure code. The calculator will determine the last day of the global period.
Q1: What are typical global periods?
A: Global periods are typically 0, 10, or 90 days depending on the procedure. Minor procedures often have 10-day global periods, while major surgeries usually have 90-day periods.
Q2: How do I find the global days for a procedure?
A: The global period length is determined by the CPT code. You can find this information in the Medicare Physician Fee Schedule or coding references.
Q3: Does the global period include the day of surgery?
A: Yes, the day of surgery is day 0, and the global period begins the day after (day 1).
Q4: What services are included in the global period?
A: The global period includes all necessary services related to the surgery, including postoperative visits, treatment of complications, and follow-up care.
Q5: Are there exceptions to global period rules?
