Surgery Global Calculator
Free global surgery calculator for Medicare, Palmetto GBA, and commercial payers. Compute global periods, post-op end dates, and CPT-based global days (90-day / 10-day / 0-day).
Global Surgery Period Calculator
Select procedure type, surgery date, or lookup CPT code to determine global days and postoperative end date (2026 rules).
➜ Global period: — days
➜ Surgery date: —
➜ Global period end date (last day of global package): —
➜ Postoperative follow-up inclusive: claims within this window are bundled.
Based on CMS Global Surgery guidelines (2026). 90-day global includes surgery day + 90 days post-op; 10-day global includes day of surgery + 10 days. Always verify with payer-specific policies (Palmetto GBA, Novitas, etc.).
Global Surgery Period by CPT Code (CMS 2026)
| CPT Code Range / Example | Procedure example | Global days |
|---|---|---|
| 10000–19999 (e.g., 11042) | Debridement, minor excision | 0 or 10 days* (typically 10) |
| 20000–29999 (e.g., 29827) | Rotator cuff repair, shoulder arthroscopy | 90 days |
| 30000–39999 (e.g., 31628) | Bronchoscopy, thoracic surgery | 90 days |
| 40000–49999 (e.g., 44970) | Appendectomy, colectomy | 90 days |
| 50000–59999 (e.g., 52000) | Cystoscopy, nephrectomy | 10 or 90 days (major = 90) |
| 60000–69999 (e.g., 66984) | Cataract extraction, vitrectomy | 90 days |
| 70000–79999 (radiology / medicine) | Non-surgical procedures | 0 days |
| 99211–99215 (E/M) | Office/OP visits unrelated to surgery | 0 days |

What is a Global Surgery Period?
The surgery global calculator determines the global surgical package defined by CMS and private payers. The global period includes the operative procedure, preoperative visits (day before major surgery), and postoperative care. Accurate calculation helps surgeons, coders, and billers avoid claim denials. In 2026, the rules remain stable: major surgeries (90-day global), minor (10-day), and endoscopic (0-day).
90‑day global period
For major surgeries (e.g., total knee arthroplasty, CABG). Includes day of surgery + 90 days of follow-up care. Global surgery calculator for major procedures ensures you don't separately bill E/M services during this window.10‑day global period
Minor procedures (carpal tunnel release, lesion excision). Post-op care bundled for 10 days. Use our 10 day global surgery calculator to track end dates.0‑day / endoscopic
Endoscopies, minor procedures with no significant post-op. For example, diagnostic colonoscopy or cataract surgery? Actually cataract is 90-day, but many GI endoscopies are 0-day global.Palmetto GBA & Novitas
MACs like Palmetto GBA, Novitas, and Jurisdiction J Part B follow CMS global surgery rules but may have local coverage. Our palmetto gba global surgery calculator methodology mirrors their guidelines. Always check LCDs.How to Use This Global Surgery Calculator (Step-by-Step)
1 Select the procedure type (major, minor, or custom days). Alternatively, enter a CPT code for instant global days estimation.
2 Pick the exact surgery date – the day of intervention.
3 Click “Calculate global period & end date” – the tool returns total global days and the final date of global package (post-op period).
4 Use result for billing compliance: avoid separate billing for postoperative E/M services unless unrelated to the surgical diagnosis.
This tool acts as a global surgery period calculator for 2026, ideal for medical coders, practice managers, and surgeons in the United States.
Exclusive Insight: 2026 Global Surgery Documentation Checklist
- ✓ Verify global period days using CMS’s PFS Relative Value File (updated April 2026).
- ✓ Palmetto GBA and Novitas require modifier -24 or -25 for unrelated E/M during global.
- ✓ For cataract surgery global period (90 days), post-op refraction and routine follow-up are bundled.
- ✓ Use global surgery calculator by CPT code free before scheduling post-op visits.
- ✓ For major 90‑day procedures, note that transfers of care must be documented with modifier -54/-55.
Quick tip: Always run the global surgery date calculator prior to submitting claims to reduce audits. As of 2026, telemedicine postoperative services are still bundled within the global package unless separate telehealth policy applies.

A 90 day global surgery calculator computes the end date of postoperative care for major procedures. Enter surgery date → adds 90 days (including day of surgery) to give global period end date, crucial for billing compliance.
Palmetto GBA follows CMS global surgery rules. Our calculator mirrors Palmetto's methodology, but we recommend cross-checking with their LCDs for specific CPT codes. It remains accurate for 2026.
Yes. The tool is based on CMS global surgery period definitions (90/10/0 days). Medicare contractors such as Novitas, Palmetto, and Jurisdiction J Part B accept these global days. Always verify individual CPT.
Cataract surgery (CPT 66984) has a 90-day global period. Our cataract surgery global period calculator helps ophthalmology practices track post-op end dates to avoid billing errors. Same for other intraocular procedures.
Absolutely. Enter any CPT code in our lookup field above to get an approximate global days value. For exact days, refer to CMS physician fee schedule or NCCI edits.
Minor procedures (e.g., trigger finger release) include 10 days of post-op care. The 10‑day global surgery calculator will display the exact follow-up cutoff. After 10 days, E/M may be separately billed.
2026 retains same global packages: 0, 10, 90 days. However, updates to telehealth and split/shared visits may impact billing within global periods. Our calculator reflects 2026 calendar compliance.
