Overview
The Global Surgical Package is the CMS payment rule that bundles pre-operative, intra-operative, and post-operative care into a single surgical payment. Each surgical CPT code has an assigned global period — 0 days (minor procedures), 10 days (intermediate), or 90 days (major) — during which routine post-operative care by the surgeon is not separately billable. The global concept exists in Medicare and is typically followed by commercial payers.
Services included in the global package include the preoperative visit immediately before surgery, the surgery itself, all routine intraoperative services, postoperative visits related to the surgery for the global period duration, and routine post-surgical care (dressing changes, suture removal). The global payment compensates the surgeon for the full bundle.
Services NOT included in the global and therefore separately billable include unrelated visits during the global period (with modifier 24), the E/M visit on the day before or the day of a major surgery that results in the initial decision to operate (with modifier 57), subsequent unrelated surgery during the global period, and procedures for complications requiring return to the operating room (with modifier 78).
Modifier application during global periods is a high-audit-attention coding area. Unsupported modifier use to bill for services during global periods is a common OIG focus. Accurate application requires documentation supporting the modifier rationale.
For RCM operations, global-period awareness is critical for surgical specialties. Practice management systems should include global-period tracking: automatically suppressing claims for visits during the global period without modifier support, prompting coders for modifier review when visits fall within the global period, and flagging unusual global-period claim patterns for compliance review.
The education angle on Global Surgical Package matters more than the raw definition. Coders who understand the clinical rationale behind Global Surgical Package — why the documentation standard exists, which services it separates, and which payer-specific modifiers the pair demands — write cleaner claims on the first pass and produce fewer denial-recovery cycles on modifier 24. A 30-minute monthly team huddle focused on a specific Global Surgical Package pattern is frequently the highest-ROI coding intervention a practice can run.
Coders working with Global Surgical Package see the edge cases most often at the coding-documentation boundary. Payer-specific coverage policies, LCDs, NCDs, and local guidance on Global Surgical Package change more often than the underlying clinical text implies, so a reviewer-authored crosswalk between the coding convention and the associated modifier 24 workflow is one of the cheapest CDI interventions available. Global Surgical Package is also where a well-maintained claim scrubber earns its keep — the cost of a single mis-coded claim downstream is usually 5–10× the cost of the scrub rule that would have caught it.
Industry benchmark
Global periods: 0 days (minor procedures like excisions), 10 days (intermediate procedures), 90 days (major surgeries). CMS publishes global-period classification in the physician fee schedule.
Worked example
A surgeon performs a cholecystectomy (CPT 47562) with a 90-day global period. Post-operative visits during the first 90 days are not separately billable. A patient return visit on day 30 for an unrelated shoulder injury receives modifier 24 on the E&M code, making it separately billable. An infection requiring return to surgery on day 15 receives modifier 78 on the second procedure.

Frequently asked questions — Global Surgical Package
How long is a global period?
0, 10, or 90 days depending on the procedure. CMS classifies each CPT code in the physician fee schedule. Major surgeries are typically 90 days; minor procedures 0 or 10 days. A 90-day global period counts the day before surgery, the day of surgery and the 90 days after it (92 days in all); a 10-day period counts the surgery day and the 10 days after it.
Are all payers following Medicare global periods?
Most commercial payers follow Medicare's global-period classifications but not all. Some payers apply their own global policies; review payer contracts and companion guides for specifics.
What modifiers override the global package?
Modifier 24 (unrelated E&M during global), 25 (significant separate E&M same day), 57 (decision for surgery), 78 (return to OR for complication), 79 (unrelated procedure during global). Each has specific use criteria.
