What does the term "global period" refer to in surgery coding?

The term "global period" in surgery coding specifically refers to the timeframe during which all necessary follow-up visits related to a surgical procedure are included in the surgical fee. This concept is essential because it defines what services are bundled together as part of the overall cost of the surgery, including the surgical procedure itself and any routine postoperative care that may be required within the designated global period.

Typically, the global period can vary depending on the type of surgery performed and can be classified into different categories, such as 0-day, 10-day, or 90-day global periods. This means that within the respective timeframe following the surgery, the provider does not bill separately for follow-up visits or related care unless complications arise or additional procedures are required.

Understanding the global period is crucial for ensuring accurate coding, billing, and compliance with payer requirements. It helps healthcare providers plan for postoperative care without incurring additional charges for routine follow-up. Other definitions, such as the duration from diagnosis to surgery or the time frame for filing insurance claims, do not accurately capture the significance of the global period in the context of surgical coding.
