Surgical Precision for Your Revenue Cycle.
General surgery billing services demand the same attention to detail as the OR itself. From 90-day global surgical packages to multiple procedure reductions and assistant surgeon billing, every claim carries layers of rules that generic billing teams routinely get wrong.
In general surgery, the global surgical package is where most revenue leaks begin.
The 90-day global period for major procedures bundles pre-operative evaluation, intraoperative services, and all routine post-operative care into a single reimbursement — and payers enforce it aggressively. When a surgeon returns to the OR during that global window, the wrong modifier means the new procedure pays zero. When an APP assists and modifier -80 or -82 is missing, the assistant fee gets denied. When multiple procedures are performed together, NCCI edits auto-bundle codes that should be billed separately — unless the right modifier is in place. General surgery billing services require coders who know these rules at the code level, not just the concept level.

Global Surgical Package Compliance (0, 10, and 90-Day Periods)
Every surgical procedure carries a CMS global period indicator — 0 days (minor), 10 days (minor with post-op), or 90 days (major). During that window, all related E/M visits, follow-up care, and post-op complications are bundled into the original surgical payment. Billing a routine post-op visit during the 90-day global period without a modifier is a guaranteed denial. Practices that don't track global periods systematically write off thousands in billable services or trigger overpayment audits — whichever direction the error runs.
Modifier Usage: -58, -78, -79, and -24
Four modifiers govern almost every post-operative billing scenario in general surgery. Modifier -58 covers staged or related procedures planned at the time of the original surgery. Modifier -78 applies when the surgeon must return to the OR to address a complication. Modifier -79 covers unrelated procedures performed during the global period. Modifier -24 is required for E/M services during the post-op window that are completely unrelated to the original diagnosis. Using the wrong modifier — or omitting it — causes the service to be bundled into the global payment with no separate reimbursement.
NCCI Edits and Multiple Procedure Reduction
The National Correct Coding Initiative (NCCI) flags code pairs that shouldn't be billed together — and general surgery generates more NCCI edit exposure than almost any other specialty. When multiple procedures are performed in the same session, CMS applies a multiple procedure reduction (typically 50% on the lesser procedure). Modifier -51 identifies these secondary procedures for commercial payers. Billing without it, or incorrectly billing component procedures as standalone codes, constitutes unbundling — triggering denials, audits, or clawbacks.
Assistant Surgeon and Co-Surgeon Billing
When a second surgeon assists, the assistant bills modifier -80 (when no qualified resident is available) or -82 (when the teaching setting requires a non-resident assistant). Many commercial payers require prior authorization before an assistant surgeon can bill. Without that auth — or without the correct modifier — the assistant fee is denied entirely. Co-surgery scenarios (modifier -62) require both surgeons to document their individual contributions, or payers will bundle the second surgeon's claim.
Standardized Happy Billing Benchmarks:
98%+ First-Pass Clean Claim Rate
Surgical claims fail at the modifier level more than any other. Our pre-submission scrubbing validates global period status, modifier selection (-58, -78, -79, -24, -80, -82), and NCCI edit pairs before every claim submission — not after the denial comes back.
Under 35 Days A/R
High-dollar surgical claims sitting in A/R aging represent significant cash flow risk. Our 24/7 follow-the-sun team keeps claims moving and denials worked before aging thresholds trigger payer challenges.
Proactive Prior Authorization Tracking
Elective surgical procedures require pre-authorization from most commercial payers, and assistant surgeon fees often require separate authorization. We manage the full PA lifecycle — submission, follow-up, and documentation — so procedures aren’t performed without guaranteed coverage.
Zero Revenue Left in the Global Period
Our global period tracking system flags every post-operative encounter and determines in real time whether an E/M is bundled, separately billable with a modifier, or a new post-op visit that should be documented differently.
Our Specialized Process
Pre-Submission Operative Note Audit
We review operative notes before claim submission to confirm CPT code selection, modifier appropriateness, and NCCI edit exposure. Catching unbundling risks before the claim is filed eliminates the most costly denial patterns in surgical billing.
Global Period Monitoring
We assign and track the global period for every surgical procedure performed by your practice. Follow-up visits, complications, and related procedures are automatically flagged for modifier review — preventing both bundling errors and fraudulent separate billing.
Multiple Procedure & Modifier Validation
Each claim involving more than one procedure is reviewed for correct modifier -51, -59, and NCCI override modifier usage. This protects against both automatic bundling denials and compliance exposure from incorrect unbundling.
Assistant Surgeon & Authorization Management
We verify assistant surgeon authorization requirements by payer before every scheduled procedure. Assistant fees are billed with the correct modifier (-80 or -82) and documentation, so this revenue stream doesn't disappear at adjudication.

Frequently Asked Questions
What's included in the 90-day global surgical package?
The global package includes all pre-operative visits on the day before or day of surgery, all intraoperative services, and all routine post-operative care for 90 days after major procedures. Follow-up visits related to recovery, suture removal, and complication management are bundled. Services that fall outside the global — such as treatment for a new, unrelated condition — require modifier -79 or -24 to bill separately.
How should we bill if a patient returns to the OR during the global period?
