What is a Global Period in Medical Billing?

A global period in medical billing refers to the timeframe (0, 10, or 90 days) following a surgical procedure during which all related preoperative, intraoperative, and postoperative services are bundled into a single payment.

This prevents duplicate billing for follow-up care tied to the original procedure.

Key Components of Global Periods

Global Period Modifiers in Medical Billing

- Modifier 24: Use for unrelated E/M services during the global period.
- Modifier 58: For staged/procedural services within 90 days.
- Modifier 25: Significant, separately identifiable E/M on the same day.
  Example: A patient with a post-op infection (unrelated to surgery) billed with Modifier 24.

Global Period Days & CPT Codes

- - 90-Day Global Period: Major surgeries (e.g., CPT 49505 hernia repair).
  - 10-Day Global Period: Minor procedures (e.g., CPT 11400 lesion excision).
  - 0-Day: No follow-up care included (e.g., diagnostic tests).
    Pro Tip: Use the CMS Global Surgery Booklet or AAPC’s CPT® Global Period Calculator to verify days.

Global Period Scenarios & Denial Solutions

Case Study 1

Scenario: A patient returns 20 days post-appendectomy (90-day global) for chest pain.
Solution: Bill with Modifier 24 + documentation proving the visit was unrelated.

Case Study 2

Denial Reason: Overlapping global periods for a staged procedure.
Fix: Append Modifier 58 and submit operative notes.

Tool Recommendation: Track global periods using billing software like Epic or Medisoft to avoid overlaps.

How Global Periods Impact Revenue Cycles

Avoid Underpayments: 30% of denials stem from missing modifiers (AAPC 2023 data).
Compliance: CMS audits flag unbundling errors, leading to penalties.
Patient Trust: Transparently explain “global fees” to reduce disputes.

Pro Tips to Master Global Periods

Audit Regularly: Review 5% of claims monthly for modifier accuracy.
Educate Providers: Train surgeons on documentation requirements for staged procedures.
