1. What is the CPT Post Op Calculator?

The CPT Post Op Calculator determines the end date of the global surgical period by adding the CPT code's designated global days to the surgery date. This helps medical professionals determine when postoperative care transitions from the surgeon's responsibility to general follow-up.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Surgery\ Date \) — The date when the surgical procedure was performed
• \( CPT\ Global\ Days \) — The standard global period days assigned to the specific CPT code

Explanation: The calculation accounts for calendar days (not just business days) to determine the exact end date of the global surgical period.

3. Importance of Global Period Calculation

Details: Accurate global period calculation is crucial for proper billing, determining when separate evaluation and management services can be billed, and understanding the surgeon's postoperative care responsibilities.

4. Using the Calculator

Tips: Enter the exact surgery date and the global days associated with the CPT code. The calculator will determine the last day of the global period.

5. Frequently Asked Questions (FAQ)

Q1: What are the typical global periods for CPT codes?
A: Common global periods are 0 days (end on day of surgery), 10 days, or 90 days, depending on the procedure complexity.

Q2: Does the calculation include the surgery date?
A: Yes, the surgery date counts as day 0, and the global period includes all subsequent days up to the specified number.

Q3: How are weekends and holidays handled?
A: The calculation includes all calendar days, including weekends and holidays.

Q4: What if the CPT code has a 90-day global period?
A: The calculator works the same way - it will add 90 days to the surgery date to determine the end of the global period.

Q5: Can this be used for procedures with no global period?
A: For procedures with 0 global days, the calculator will return the surgery date itself as the global end date.
