Upcoding and Unbundling: How Providers Inflate Bills
What are upcoding and unbundling on a medical bill?
Upcoding is billing for a more expensive procedure than what was performed, while unbundling is billing separately for services that should be included in one bundled fee. Compare the CPT codes on your itemized bill to your medical records to catch them, and report suspected fraud to the HHS Office of Inspector General.
Some of the most costly medical billing errors are not simple mistakes; they are intentional strategies to inflate your bill and get more money from your insurance company. Two of the most common and deceptive of these strategies are upcoding and unbundling. These are not just aggressive billing tactics; they are forms of billing fraud. Understanding how these schemes work is the first step to identifying them on your bill and fighting back.
Failure Mode: Upcoding
Upcoding is when a provider bills for a more expensive or complex service than the one that was actually provided. Every medical service is assigned a specific CPT (Current Procedural Terminology) code, and upcoding involves using a code for a higher-level service to get a higher reimbursement.
How Upcoding Works
An office visit with a doctor is typically billed using one of five E&M (Evaluation and Management) codes, from a simple Level 1 visit to a complex Level 5 visit.
A doctor might provide a routine, 15-minute follow-up visit (a Level 2 service) but bill for a 45-minute, complex consultation (a Level 4 service). The difference in reimbursement can be hundreds of dollars.
How to Spot Upcoding
1. It's Difficult Without Medical Records
The only way to know if you have been upcoded is to compare the CPT code on your itemized bill to the documentation in your visit note. The note must contain a certain level of detail about your history, physical exam, and the complexity of the medical decision-making to justify a higher-level code.
2. Trust Your Instincts
If the charge for a service seems unusually high for a routine visit, it is worth investigating for upcoding. A simple 10-minute visit should not generate a $500 charge.
3. Look at Visit Duration
Higher-level E&M codes require more time. If you were only in the exam room for 15 minutes, it's unlikely the visit qualifies for a Level 4 or 5 code which typically require 30-60 minutes.
| E&M Level | Typical Time | Complexity | Documentation Required |
|---|---|---|---|
| Level 1 | ~10 minutes | Very simple | Minimal history, exam, decision-making |
| Level 2 | ~20 minutes | Simple | Brief history, limited exam, straightforward decision |
| Level 3 | ~30 minutes | Moderate | Detailed history, expanded exam, moderate complexity |
| Level 4 | ~45 minutes | High | Comprehensive history/exam, high complexity decision |
| Level 5 | ~60 minutes | Very high | Extensive documentation, very high complexity |
Failure Mode: Unbundling
Unbundling (also called "fragmentation") is when a provider bills separately for services that should be included together in a single, bundled charge. Many surgical procedures have a single "global" fee that includes all of the routine components of that procedure. Unbundling is the practice of billing for these components individually to get a higher total reimbursement.
How Unbundling Works
A surgeon performs a knee replacement. The global fee for this procedure includes the cost of opening the incision, the work of replacing the joint, and the cost of closing the incision.
An unscrupulous biller might "unbundle" this and bill separately for the surgery itself, the sutures used to close the wound, the sterile dressing, and post-operative pain management—all of which should be included in the single global surgical fee.
How to Spot Unbundling
1. Look for Multiple Small Charges Around One Major Procedure
If you have had surgery, look at your itemized bill for a long list of small charges related to that single surgical procedure. These may be unbundled charges.
2. Watch for These Common Unbundled Items
- Wound closure or sutures (usually included in surgical fee)
- Sterile trays and surgical supplies (usually included)
- Post-operative pain management (usually included for 90 days)
- Anesthesia monitoring during surgery (may be separately billed by anesthesiologist but not surgeon)
- Routine follow-up visits within the global period (usually included)
3. Use Your Operative Report
Your operative report describes everything that was done during your surgery. Use it to understand the scope of the procedure and question any charges that seem like they should have been part of the main event.
How to Fight Upcoding and Unbundling
Step-by-Step Action Plan
- 1.Get Your Complete Records: You cannot win this fight without evidence. You need both your itemized bill and your complete clinical medical record for the date of service.
- 2.Identify the Suspicious Charges: Highlight the charges on your bill that you suspect are upcoded or unbundled. Note the CPT codes.
- 3.Research the CPT Codes: Look up the CPT codes on the American Medical Association (AMA) website or ask a medical billing advocate to explain what level of service each code represents.
- 4.Compare to Your Medical Record: For upcoding, verify that the documentation in your visit note or operative report supports the level of service billed. For unbundling, verify that separate charges should not have been included in a global fee.
- 5.Write a Formal Dispute Letter: Write to both the provider's billing department and your insurance company. State that you believe you have been a victim of upcoding or unbundling and provide specific evidence from your medical records.
- 6.Report Suspected Fraud: If you have clear evidence of intentional upcoding or unbundling, you can report it to the Office of the Inspector General for the U.S. Department of Health and Human Services.
Sample Language for Upcoding
"I am disputing the charge for CPT code [XXXXX] on [Date]. My visit note does not contain documentation of the detailed history, comprehensive examination, or high-complexity medical decision-making required to support this level of service. The documentation only supports a Level [X] visit. Please adjust the charge accordingly."
Sample Language for Unbundling
"I am disputing the separate charges for [wound closure/sutures/sterile tray] on [Date]. These services should be included in the global surgical fee for my [procedure name]. Medicare's National Correct Coding Initiative indicates these services are bundled. Please remove these charges."
Why This Matters
Financial Impact
Upcoding a single office visit from Level 2 to Level 4 can add $100-300 to your bill. Unbundling a surgical procedure can add thousands in fraudulent charges.
Insurance Premiums
Widespread billing fraud drives up insurance costs for everyone. When providers get away with upcoding and unbundling, insurers raise premiums to cover the fraudulent payments.
It's Illegal
Intentional upcoding and unbundling are violations of the False Claims Act. Providers can face substantial fines and even criminal prosecution for systematic billing fraud.
