90-Day Global Surgery Period Calculator
If you work in medical billing, you understand the importance of accurately tracking global surgery periods.
Mistakes can lead to denied claims, compliance issues, and lost revenue.
A 90-day global calculator simplifies this process by giving you the exact dates when a global surgery period begins and ends for payment purposes.
At The Auctus Group, we’ve designed a Global Period Calculator that makes it easy to determine which CPT codes have a 90-day global period and when that period expires.
What Is a 90-Day Global Surgery Period?
A 90-day global period is the timeframe following surgery during which the original payment for the procedure includes both follow-up care and any additional services that may be necessary.
It means you can’t bill separately for most post-op visits during this period unless notable exceptions apply.
Types of Global Surgery Periods
- 0-Day Global Period – Only the day of surgery is covered.
- 10-Day Global Period – Covers minor surgeries with limited post-op care.
- 90-Day Global Period – Includes pre-op, surgery, and post-op care for major procedures.
If you bill for services incorrectly during a global period, your claims may be denied or flagged for review.
That is why a reliable calculator is essential.
Why Accurate 90-Day Global Period Calculations Matter
Let’s take a look at why Global Period Calculations should matter to you:
Avoid Claim Denials
If you bill for services within a global period, Medicare and insurance companies may deny payment, assuming the care is already covered.
Get Paid on Time
Incorrect billing delays reimbursements.
Knowing exactly when a global period ends helps you submit claims at the right time.
Stay Medicare-Compliant
Mistakes with global period calculations can trigger audits, fines, and other compliance issues.
Maintaining accurate records safeguards your practice against these risks.
How to Calculate a 90-Day Global Period
A global surgery period calculator makes this process quick and straightforward.
Here’s how it works:
Step 1: Identify the CPT Code
Not all procedures have a 90-day global period.
You need to check the CPT code to determine whether a procedure falls under this category.
Our Global Surgery Calculator helps you instantly verify which CPT codes have a 90-day global period.
Step 2: Enter the Surgery Date
The global period starts on the day of the surgery.
Step 3: Find the End Date
- The 90-day count includes weekends and holidays.
- The period ends 90 days after surgery.
- If surgery occurs at the end of the month, adjustments may be necessary.
- Keeping track of these dates manually is time-consuming and prone to errors.
That’s why an automated calculator, such as our Global Period Calculator, is the best solution.

FAQs
What is a 90-day global period?
A 90-day global period is the timeframe following surgery during which the original procedure payment includes both follow-up care and any additional services that may be necessary. During this period, Medicare and most insurance providers do not reimburse separately for routine post-operative visits, as the initial surgical payment bundles them.
How do you calculate global periods?
To calculate a global period, start by identifying the CPT code for the procedure. If the procedure has a 90-day global period, count 90 consecutive days from the date of surgery, including weekends and holidays, to determine the duration. The period begins on the day of surgery and ends at midnight on the 90th day. Using an automated 90-day post-op calculator simplifies this process and ensures accuracy.
How many days is the 90-day global period?
The 90-day global period lasts exactly 90 days from the day of surgery, including weekends and holidays. Some providers mistakenly exclude weekends, but Medicare counts all calendar days as working days.
How to solve global period denial?
If a claim gets denied due to the global period, first verify the CPT code and surgery date to confirm whether the service happened within the 90-day timeframe. If they rejected the claim incorrectly, submit an appeal with supporting documentation. If the service was unrelated to the surgery, use appropriate modifiers (e.g., modifier 24 for unrelated E/M services) to indicate it was medically necessary and not part of post-op care.
What is an example of a global period?
An example of a 90-day global period would be a total knee replacement (CPT 27447). If the surgery occurs on March 1st, the global period ends on May 30th at midnight. Any routine post-operative visits within this period are included in the initial payment and cannot have separate bills.
What are the global days?
Global days refer to the number of days following a surgical procedure during which the original payment includes post-operative care. Procedures fall into three categories: a 0-day global period (minor procedures with same-day coverage), a 10-day global period (minor surgeries with limited follow-up), and a 90-day global period (major surgeries with extended post-operative care included). You can use the global days calculator to check specific CPT codes and avoid billing errors.
