As the healthcare landscape continues to evolve, accurate medical billing and coding remain vital to the financial success of cardiology practices. Among the many billing concepts that physicians need to understand, one of the most misunderstood — yet essential — is the "global period." For cardiologists, a firm grasp of global periods is crucial to ensuring proper reimbursement, maintaining compliance, and avoiding costly billing errors.
This article breaks down what global periods are, how they apply to cardiology procedures, and how professional Cardiology Billing Services like P3 Healthcare Solutions can help you navigate this complex part of the revenue cycle with confidence.
What Is a Global Period?
The "global period" refers to a specific timeframe during which all services related to a surgical or interventional procedure are considered part of the overall package and, therefore, not separately reimbursed. It includes pre-operative, intra-operative, and post-operative care provided by the physician who performed the procedure.
There are generally three types of global periods assigned by Medicare and most commercial payers:
-
0-Day Global Period: Includes only the day of the procedure. Post-operative care on subsequent days is separately billable.
-
10-Day Global Period: Covers the day of the procedure and the following 10 days. Follow-up visits within this period are included in the payment for the original procedure.
-
90-Day Global Period: Includes the day before the procedure, the day of the procedure, and the 90 days following the procedure.
Understanding and accurately applying these timeframes is critical for cardiologists to prevent billing rejections and compliance issues.
Why Global Periods Matter in Cardiology
Cardiology is a specialty that involves a wide variety of diagnostic, interventional, and surgical procedures — many of which fall under global periods. Examples include:
-
Pacemaker insertions
-
Coronary artery bypass grafting (CABG)
-
Cardiac catheterizations
-
Angioplasty and stent placements
-
Electrophysiology studies and ablations
If follow-up visits or post-procedural care are incorrectly billed during the global period, they may be denied or flagged as billing errors. Conversely, if services that fall outside the global period are bundled inappropriately, it could result in lost revenue.
Common Mistakes in Cardiology Global Period Billing
Even experienced billing staff may encounter challenges with global period rules. Here are some of the most common pitfalls:
1. Billing for Post-Operative Visits Within the Global Period
Routine follow-up care related to the original procedure is not separately billable. For example, a cardiologist performing a stent placement with a 90-day global period cannot bill for post-procedure office visits unless they are unrelated to the original service.
2. Not Using Appropriate Modifiers
When billing for services outside the scope of the global period — even if they occur within it — modifiers are crucial. For example:
-
Modifier 24: Used for unrelated evaluation and management (E/M) services during the post-op period.
-
Modifier 25: Indicates that a significant, separately identifiable E/M service was provided on the same day as another procedure.
-
Modifier 78: Used for unplanned returns to the operating room during the global period.
Proper modifier usage helps ensure that payers understand the distinction and approve payment accordingly.
3. Misunderstanding Global Period Start and End Dates
The start of a global period is not always the date of the procedure — especially in cases where there is a 90-day global period that includes the day before surgery. Misinterpreting the start and end dates can result in incorrect billing and compliance issues.
How to Stay Compliant with Global Period Rules
To ensure proper billing, cardiology practices should adopt the following best practices:
1. Track Global Periods by Procedure
Use your billing system to track the start and end dates of global periods for every surgical or interventional procedure. This prevents accidental billing for included services.
2. Educate Clinical Staff
Ensure that physicians and medical assistants understand what services are included in the global period and when documentation must support a separate, unrelated service.
3. Implement Clear Documentation Protocols
Detailed documentation is key. When billing for a visit during the global period, the record must clearly state that the visit was unrelated to the original procedure.
4. Audit Regularly
Routine internal audits of procedure codes and post-op visits help catch and correct billing errors before they result in denials or compliance flags.
