In CPT coding, what do the terms "global period" refer to?

The term "global period" in CPT coding specifically refers to the duration during which all related services associated with a surgical procedure are considered part of that procedure. This means that during the global period, which usually lasts for a predetermined number of days (commonly 10 or 90 days, depending on the procedure), the surgeon and other healthcare professionals cannot bill separately for any routine postoperative care. This encapsulates all follow-up visits and related care under the initial procedure’s code, simplifying the billing process and emphasizing the continuum of care for the patient's recovery.

In addition, understanding the global period is crucial for proper coding and billing practices, as it helps ensure that healthcare providers account for all necessary services provided to a patient without unintentionally overcharging for post-surgical follow-ups. Recognizing that the global period comprises related services reinforces the importance of comprehensive care throughout the patient's recovery journey.
