Case Study: General Surgery Medical Billing Turnaround—29% to 7% Denial Drop
Introduction
General surgery medical billing is full of complications. From complex CPT coding to bundled surgical packages and documentation demands, there’s plenty that can go wrong. In fact, even small mistakes can lead to claim denials or payment delays. This case study shares how Medical Billing Wholesalers (MBW) helped a multi-specialty surgical group improve their billing process, reduce denials, and recover faster payments within just 90 days.
Client Overview
Location: Illinois, USA
Specialty: General Surgery (laparoscopic, colorectal, emergency)
Monthly Surgeries: 200+
Average Monthly Claims Billed: $400,000
Initial Claim Denial Rate: 29%
The client faced frequent denials, poor modifier usage, and missing documentation. Together, these issues severely affected their general surgery medical billing workflow.
Key Challenges in General Surgery Medical Billing
The group encountered multiple billing problems. Each contributed to lower collections and an overwhelmed A/R team:
Incorrect CPT and ICD-10 Codes
General surgery medical billing often requires multiple codes per procedure. However, confusion between open and laparoscopic codes (e.g., 44950 vs. 44970) caused repeated denials and revenue loss.Misunderstood Global Surgical Packages
Surgeons were billing separately for post-op visits already included in the global period, leading to automatic denials from payers.Improper Modifier Usage
Modifiers like 59, 22, 78, and 79 were either missing or incorrectly applied. Therefore, surgical complexity was not accurately reflected in the claims.Medical Necessity Denials
Claims for hernia repairs and other elective surgeries lacked imaging reports or failed treatment evidence, leading to rejections for lack of necessity.Delayed Claims and A/R Pile-Up
Follow-ups on unpaid claims weren’t happening until 60+ days. As a result, the backlog kept growing.
Our Solution: Step-by-Step Billing Intervention
To solve these issues, MBW applied a multi-layered solution. Here's how we tackled each roadblock in their general surgery medical billing cycle:
1. Certified Coding Audits
Trained surgical coders reviewed every claim. They ensured CPT and ICD-10 codes were applied correctly, preventing upcoding, downcoding, or mismatches between procedures.
2. Global Package Education
We trained both surgeons and billers to identify services within the global surgical period. Moreover, we updated the EHR templates to auto-flag post-op services and avoid redundant billing.
3. Modifier Mapping Logic
Rules for modifier use were built into the billing software. This ensured appropriate application of modifier 59, 22, 78, and 79—based on payer policy.
4. Documentation Improvement Support
Our CDI experts introduced checklists to help surgeons improve their notes. This included adding medical necessity details like imaging, diagnostics, and prior treatments.
5. Early A/R Follow-Up
Payers were contacted by Day 21. Claims beyond 30 days were escalated. Additionally, A/R reports were shared monthly to keep the team accountable.
Measurable Results in 90 Days
| Metric | Before MBW | After MBW |
|---|---|---|
| Claim Denial Rate | 29% | 7% |
| Average Days in A/R | 64 days | 33 days |
| First-Pass Clean Claims | 58% | 92% |
| Modifier-Related Denials | 19% | 3% |
| Medical Necessity Denials | 21% | 5% |
These results reflect real improvements in their general surgery medical billing operations. The practice reduced backlog, received faster payments, and saw far fewer denials.
