Frequently asked questions
What is a global surgery period?
A global surgery period is an administrative billing window around a procedure during which related postoperative care may be bundled by the payer. The exact period and rules depend on the payer and procedure.
Does this calculator determine the CPT global period?
No. This calculator estimates the end date after the global period length is already known. Confirm the CPT or payer-specific global period in the relevant fee schedule or billing system.
Is this clinical advice or billing advice?
No. This page is a date calculator and educational decision-support surface. It does not replace payer policy, billing review, coding guidance, or clinician judgment.
