What is a Global Period in Medical Billing?
The global surgical period (also known as global package) includes all preoperative, intraoperative, and postoperative services normally furnished by a surgeon. Under Medicare and most commercial payers, global periods are either 0 days, 10 days, or 90 days. Using a global period calculator helps you determine whether to bill E/M visits separately or if they’re bundled. Updated for 2026, CMS defines three main categories: minor procedures (0-day), minor surgeries with follow-up (10-day), and major surgeries (90-day).
Types of Global Periods Explained (CMS 2026)
| Global Period Type | Days | Common Examples | Billing Notes |
|---|---|---|---|
| Minor / Endoscopy | 0 days | Injections, simple debridement, radiology guidance | All E/M services separately billable |
| Minor surgery with post-op | 10 days | Simple repair, cystoscopy, trigger finger release | Post-op visits bundled; unrelated E/M allowed |
| Major surgery | 90 days | Hernia repair, arthroscopy, colectomy, CABG, joint replacement | All routine post-op care included; modifiers -54, -55 for split care |
Why Use a 90‑Day Global Period Calculator for Major Surgeries?
Major surgical procedures such as cataract surgery, knee replacement, or spinal fusion carry a 90‑day global period. Using a dedicated 90 day global period calculator prevents underpayment or denial. Medicare and Palmetto GBA enforce strict bundling: any E/M service within the 90 days related to the surgery is not separately reimbursed unless a modifier (-24, -25, -57) applies. Our tool references CMS global surgery guidelines and Novitas solutions.
