What Is a Global Period in Medical Billing?
Understand the medical billing global period. Learn how it bundles all related care for a procedure into a single, comprehensive payment.
The global period in medical billing is a designated timeframe during which all medical services related to a surgical procedure are part of a single bundled payment. This concept, guided by the Centers for Medicare & Medicaid Services (CMS), aims to streamline billing by consolidating charges for pre-operative, intra-operative, and post-operative care. Its purpose is to prevent fragmented billing for routine services associated with a surgical event. By packaging these services, the global period helps ensure patients and payers understand the comprehensive cost of a surgical procedure upfront.
Services Included in a Global Period
A global surgical package encompasses services provided by the operating surgeon, or members of the same group with the same specialty, before, during, and after a procedure. This bundling begins with pre-operative care, including evaluation and management services. It covers any history and physical examinations performed on the day before or the day of the surgery.
Intra-operative services form the core of the global period, covering the surgery itself. This includes the procedure and all necessary components, such as local infiltration, topical anesthesia, and any immediate post-operative care in the recovery area. The surgeon’s management of the patient during the operation is integrated into this single fee.
Post-operative care extends the global period to cover routine follow-up visits and services for recovery. This includes standard wound care, dressing changes, removal of sutures or staples, and pain management provided by the surgeon. Even minor complications that do not necessitate a return to the operating room are typically included, ensuring comprehensive care without additional charges.
Services Not Included in a Global Period
While comprehensive, a global period does not cover every service a patient might receive around the time of surgery. Services unrelated to the surgical procedure itself are excluded and can be billed separately. This includes an initial consultation to determine the need for surgery, where a separate evaluation and management (E/M) service may be appropriate.
Treatment for unrelated conditions or new medical problems that arise during the global period are also separately billable. If a patient develops pneumonia after an orthopedic surgery, the treatment for pneumonia would fall outside the global package. Diagnostic tests are generally not included unless they are a routine part of the surgical follow-up.
Services rendered by different providers, such as anesthesiologists, pathologists, or radiologists, who bill independently, are usually not part of the surgeon’s global package. Significant complications requiring a return to the operating room are also typically excluded, allowing for separate billing for the additional surgical intervention.
Common Global Period Lengths
Global periods are not uniform; their duration varies based on the complexity and invasiveness of the surgical procedure. The Centers for Medicare & Medicaid Services (CMS) categorizes procedures into three primary global period lengths. These standardized periods help ensure consistent billing practices across different healthcare settings.
Minor procedures, such as some endoscopies or minor skin excisions, often have a 0-day global period. This means the global package covers only the day of the procedure, and any subsequent care is billed separately.
Other minor procedures may carry a 10-day global period. This encompasses the day of the surgery and the ten days immediately following it. Routine follow-up visits during this period are included in the initial surgical fee.
Major surgeries, which are more resource-intensive and require a longer recovery, typically have a 90-day global period. For these procedures, the global period begins one day before the surgery and includes the day of the procedure, plus the 90 post-operative days. This longer duration covers extensive follow-up care.
How Global Periods Affect Billing
Global periods significantly impact the financial aspects of healthcare for both patients and providers by consolidating charges. For patients, the global period simplifies billing because the initial surgical fee is intended to cover all included services. Once the procedure fee is paid, routine follow-up care within the specified global period generally incurs no additional charges from the operating surgeon.
This bundled payment approach provides financial predictability for patients, reducing the likelihood of unexpected bills for post-operative visits. For healthcare providers, global periods establish a single reimbursement rate for the entire surgical package. This structure discourages “unbundling,” where individual services that should be part of the surgical care are billed separately, ensuring fair and consistent payment for a complete episode of care.
Understanding these periods is important for providers to ensure accurate claim submission and avoid denials that can arise from billing for services already included in the global fee. Proper application of global period rules helps healthcare practices manage their resources effectively and maintain compliance with payer regulations.
