If you just got a bill for an upper endoscopy and saw a charge labeled CPT 43239, you are not alone in wondering what that means or whether the number is right. An upper endoscopy (also called an EGD, short for esophagogastroduodenoscopy) is a common outpatient procedure used to examine the esophagus, stomach, and upper part of the small intestine. The national median negotiated rate for CPT 43239 in 2026 is around $424 to $538 for the professional fee alone, but the total bill including facility fees can easily reach $1,500 to $4,500 depending on where the procedure was performed.
Before you pay anything, upload your hospital bill to the CoveredUSA Bill Analyzer. It compares each line item against Medicare benchmark rates so you can see in seconds whether you were overcharged.
Quick Answer: An upper endoscopy with biopsy (CPT 43239) costs $1,500 to $4,500 total in 2026 when you include facility fees, physician fees, and anesthesia. Medicare's 2026 facility payment rate for this code is approximately $311. Patients without insurance often see list prices of $2,500 or more. Ambulatory surgery centers charge 30 to 50 percent less than hospital outpatient departments for the same procedure.
What Is CPT 43239?
CPT codes are standardized billing numbers the American Medical Association maintains. Insurers and Medicare use them to determine what a procedure is and how much to pay for it. Understanding the code on your bill is the first step in verifying you were charged correctly.
For upper endoscopy, the most common codes are:
| CPT Code | Description | Typical 2026 Physician Fee |
|---|
| 43235 | Diagnostic EGD only (no biopsy, no tissue removal) | $200 to $350 |
| 43239 | EGD with biopsy (one or more tissue samples taken) | $300 to $540 |
| 43245 | EGD with dilation of gastric or duodenal stricture | $380 to $650 |
| 43251 | EGD with removal of polyp(s) by snare technique | $400 to $700 |
| 43270 | EGD with ablation of tumor, polyp, or lesion | $450 to $800 |
CPT 43239 is the most frequently billed upper endoscopy code because many diagnostic scopes also include a biopsy. If your doctor visually inspects the stomach and also removes a small tissue sample with forceps to test for H. pylori or Barrett's esophagus, CPT 43239 is the correct code.
A common billing error: some facilities bill CPT 43235 (diagnostic only) and then add a separate biopsy code on top. Under standard bundling rules, 43239 already includes the diagnostic component, so you should not see both 43235 and 43239 on the same bill. If you do, that may be an error worth disputing. The CoveredUSA Bill Analyzer flags exactly these kinds of unbundling issues automatically.
2026 Cost Breakdown: What You Are Actually Paying For
Your endoscopy bill is not a single charge. It typically includes three to four separate line items, each from a potentially different billing entity.
Facility Fee
This is the largest charge and the one with the most price variation. Hospitals and ambulatory surgery centers (ASCs) both charge facility fees, but hospital outpatient departments charge significantly more.
2026 Facility Fee Comparison (CPT 43239)
| Facility Type | Typical 2026 Range | Notes |
|---|
| Hospital outpatient department | $2,500 to $4,000 | Highest list prices; insurance negotiates down |
| Ambulatory surgery center (ASC) | $900 to $1,500 | 30 to 50% lower than hospital |
| Medicare payment (facility) | $311 | Government benchmark rate for 2026 |
The Medicare payment rate of $311 (per Medicare.gov procedure price lookup) is the single most useful benchmark you have. It represents what the federal government considers a fair facility payment for this procedure. If your facility charged three or four times that amount, the CoveredUSA Bill Analyzer can help you document the discrepancy.
Physician Fee
The gastroenterologist who performed the procedure bills separately from the facility. The 2026 physician fee for CPT 43239 is typically $300 to $540 for insured patients. Medicare's physician conversion factor for 2026 is $33.40 per relative value unit (RVU), and CPT 43239 carries a work RVU of 2.76, yielding a Medicare physician payment of roughly $92. Private insurers pay more.
Anesthesia Fee
Most upper endoscopies use moderate sedation (IV medication given by the endoscopist or a nurse) rather than full general anesthesia, but some facilities use a dedicated anesthesia provider. If so, you may receive a separate bill of $300 to $800 from an anesthesiologist or CRNA. Check whether that provider was in-network. Out-of-network anesthesia at an in-network facility is a known source of surprise bills.
Pathology Fee
If the biopsy tissue is sent to a lab, a pathologist reads the sample and bills separately. Expect $100 to $300 for a single biopsy sample read.
Total Cost Estimates for 2026
Upper Endoscopy (EGD) Total Cost by Scenario
| Scenario | Estimated Total Cost (2026) |
|---|
| Uninsured, hospital outpatient department | $2,500 to $4,500 |
| Uninsured, ambulatory surgery center | $990 to $2,200 |
| Insured, hospital (after deductible/coinsurance) | $500 to $2,000 out of pocket |
| Insured, ASC (after deductible/coinsurance) | $200 to $1,000 out of pocket |
| Medicare patient (standard 20% coinsurance) | $60 to $200 out of pocket |
| Medicaid patient | $0 to $3 copay (varies by state) |
These estimates are based on 2026 national averages reported by sources including MDsave and New Choice Health. Your actual cost depends on your specific plan, deductible status, and provider location.
Why Your Bill May Be Higher Than Expected
Several factors push endoscopy bills above the averages listed above.
Geographic variation. Prices in New York or California routinely run 40 to 60 percent above the national median. Rural markets with limited competition also see elevated prices.
Hospital markup. Hospitals often apply a charge-to-cost ratio of 3:1 or higher. The $4,000 facility fee you see on a statement may reflect a negotiated payment to the hospital of $600. You are paying a percentage of the inflated list price, not the negotiated rate your insurer actually pays.
Unbundled codes. Billing two codes when one should cover the work inflates the total. Common examples include billing for conscious sedation separately when it is already bundled into the endoscopy code, or billing 43235 plus an additional biopsy code alongside 43239.
Duplicate charges. Some patients are billed twice for the same supply or service. This happens more often than most people realize and is rarely caught without a line-by-line review.
Out-of-network providers. Even when the hospital or ASC is in-network, the gastroenterologist or anesthesiologist may not be. The No Surprises Act limits some balance billing, but it does not apply to all situations.
How to Apply and Get Help
If you received an upper endoscopy bill and cannot afford it, several paths exist to reduce or eliminate the balance. Per CMS.gov, you have a legal right to request financial assistance and dispute errors on any medical bill.
Step 1: Request an itemized statement. Call the hospital billing department and ask for a line-by-line bill with all CPT codes, charge amounts, and a description of each service. Federal law requires hospitals to provide this.
Step 2: Compare to Medicare rates. Look up each CPT code at Medicare.gov's Procedure Price Lookup. If the facility charged more than three times the Medicare rate, ask the billing department to justify the difference in writing.
Step 3: Check for errors. Verify that all procedures on the bill actually happened during your visit. Confirm CPT codes match what your doctor documented. Look for duplicate line items.
Step 4: Ask about charity care. Under the Affordable Care Act, nonprofit hospitals that receive federal tax-exempt status must offer financial assistance programs. Income limits vary, but many programs cover patients earning up to 200 to 300 percent of the federal poverty level. According to CMS.gov's financial assistance guide, you can apply even after receiving a bill.
Step 5: Negotiate a self-pay discount. If you are uninsured or your claim was denied, ask for the self-pay or cash-pay rate. Hospitals routinely discount 30 to 50 percent from the chargemaster rate for patients who pay promptly.
Step 6: Request a payment plan. If you owe a balance you cannot pay at once, ask for an interest-free payment plan. Most hospitals offer these and are required by law to accept reasonable arrangements before sending accounts to collections.
Step 7: File a dispute if needed. If you believe you were billed incorrectly and the hospital does not resolve it, you can file a complaint with your state insurance commissioner or with CMS at cms.gov/medical-bill-rights.
Documents you may need:
- Itemized hospital bill with CPT codes
- Explanation of Benefits (EOB) from your insurer
- Operative note or procedure summary from your doctor
- Proof of income (for charity care applications)
- Insurance card and member ID
- Date of service and facility name
Common reasons charity care applications are denied:
- Income documentation was incomplete or missing
- Application was submitted after the deadline (usually 240 days from billing date)
- The facility classified the service as non-emergency
- The applicant had insurance that covered part of the bill
Does Medicare Cover Upper Endoscopy?
Yes. Medicare Part B covers upper endoscopy when it is medically necessary, as outlined by CMS billing guidelines for upper GI endoscopy (Article A57414). For 2026:
- Medicare pays 80 percent of the approved amount after the Part B deductible ($283 in 2026).
- You pay the remaining 20 percent coinsurance.
- If the procedure is performed in a hospital outpatient department, you may face an additional copayment through the Outpatient Prospective Payment System.
- A Medigap supplement plan can cover the 20 percent coinsurance, leaving you with little or no out-of-pocket cost.
Medicare does not require prior authorization for most diagnostic upper endoscopies, but your doctor must document medical necessity. Common accepted indications include persistent GERD symptoms, unexplained weight loss, anemia of unknown origin, and follow-up for Barrett's esophagus.
Does Medicaid Cover Upper Endoscopy?
Medicaid covers upper endoscopy in all states when the procedure is medically necessary. Coverage details, prior authorization requirements, and copayment amounts vary by state. Most Medicaid beneficiaries pay $0 to $3 in copays per procedure.
Frequently Asked Questions
What does CPT 43239 mean on my hospital bill?
CPT 43239 is the billing code for an esophagogastroduodenoscopy (upper endoscopy) with biopsy. It means the gastroenterologist used a flexible scope to examine your esophagus, stomach, and upper small intestine and also removed at least one tissue sample for lab analysis. As of 2026, the Medicare-approved facility payment for this code is $311.
What is the average cost of an upper endoscopy in 2026?
The national average total cost ranges from $1,500 to $4,500 in 2026, depending on facility type, location, and what additional procedures were performed. Hospital outpatient departments average $2,500 to $4,000 for the facility fee alone. Ambulatory surgery centers average $900 to $1,500 for the same service.
How much does an upper endoscopy cost without insurance?
Without insurance, expect to pay $2,500 to $4,500 at a hospital or $990 to $2,200 at an ambulatory surgery center in 2026. Many facilities offer self-pay discounts of 20 to 50 percent if you ask. You can also apply for the hospital's charity care program if your income qualifies.
What is the difference between CPT 43235 and CPT 43239?
CPT 43235 is a diagnostic-only upper endoscopy where the doctor looks but does not take tissue. CPT 43239 includes everything in 43235 plus a biopsy. If both codes appear on the same bill, that is likely a billing error, since 43239 already bundles the diagnostic component.
Can I negotiate an endoscopy bill after I receive it?
Yes. You can request an itemized bill, check charges against Medicare rates, ask for a self-pay discount, apply for charity care, or set up a payment plan. Hospitals are legally required to provide itemized statements and financial assistance applications under federal law. The CFPB outlines your rights in detail.
Does Medicare cover CPT 43239?
Yes. Medicare Part B covers CPT 43239 when medically necessary. After meeting the Part B deductible ($283 in 2026), Medicare pays 80 percent of the approved amount and you pay 20 percent. With a Medigap plan, your out-of-pocket cost may be near zero. Details are available at Medicare.gov.
How do I find out if I was overcharged for an endoscopy?
Request an itemized bill with all CPT codes. Look up each code using the Medicare Procedure Price Lookup at Medicare.gov. Compare the facility's charge to the Medicare rate. Upload your bill to the CoveredUSA Bill Analyzer at coveredusa.org/medical-bill-analyzer to get a line-by-line comparison against benchmark rates in under 30 seconds.
What are common billing errors on endoscopy bills?
The most frequent errors include: unbundling (billing 43235 and a separate biopsy code when only 43239 should be used), charging for conscious sedation separately when it is already included in the procedure code, duplicate charges for the same supply, and billing for an anesthesiologist when only moderate sedation was given by the endoscopist.
