Scoping a horse for gastric ulcers typically costs between $250 and $600 total, depending on where you live, whether the vet comes to your barn or you haul in to a clinic, and how many add-on fees stack up. The procedure itself (called a gastroscopy) usually runs $150 to $350, but that base price rarely reflects the final bill. Sedation, farm call charges, and facility fees can add $100 to $250 on top.
What’s Included in the Base Price
When a vet quotes you a gastroscopy price, they’re typically quoting for the use of the endoscope and the interpretation of what they see on camera. That base fee covers passing a long, flexible scope through your horse’s nostril, down the esophagus, and into the stomach while your horse stands sedated in stocks. The vet examines the stomach lining in real time, grades any ulcers on a 0 to 4 scale, and gives you results on the spot.
What’s usually not included: sedation, the trip to your farm (or the haul-in fee if you trailer to a clinic), and any additional medications dispensed the same day. These get billed as separate line items, and they can meaningfully change the total.
The Add-On Fees That Raise Your Bill
Sedation is always an extra charge. Most vets use one or two drugs in combination to keep the horse calm and still for the scope. Based on the AAEP’s veterinary fee survey, common sedation drugs average $35 to $45 each, including administration. Your horse will likely need at least one, possibly two, putting sedation costs in the $35 to $90 range.
If a mobile vet comes to your barn, you’ll pay a farm call fee. The national average is about $59 for trips within 10 miles, climbing to around $69 for 11 to 20 miles and $81 for 21 to 30 miles. Farther distances push that number past $100. Some vets charge a flat mileage rate of $2 to $4.50 per mile instead.
If you haul your horse to a clinic, the outpatient or haul-in fee is much cheaper, averaging about $26. That’s a significant savings over a farm call, especially if you live far from your vet. The tradeoff is your time, fuel, and the stress of trailering a horse that may already be uncomfortable.
Sample Cost Breakdown
- Gastroscopy procedure: $150–$350
- Sedation (1–2 drugs): $35–$90
- Farm call (within 20 miles): $59–$69, or haul-in fee of ~$26
- Estimated total at a clinic: $250–$450
- Estimated total with farm call: $300–$600
University veterinary hospitals and specialty equine practices tend to charge at the higher end. Rural ambulatory vets with their own portable scopes are often more affordable, though not every mobile vet owns the three-meter endoscope needed to reach a horse’s stomach.
What Happens During the Scope
The entire appointment takes about two hours from arrival to when your horse is back in a stall, though the actual scoping portion lasts 40 to 60 minutes. Your horse will need to fast beforehand: no hay, grain, grass, treats, or water for 10 hours before the procedure. An empty stomach is essential because even a small amount of feed blocks the camera’s view of the stomach lining.
Once sedated, the horse stands in stocks while the vet feeds the endoscope through one nostril. The scope has a camera on the tip and a channel that can push air or water into the stomach to inflate it for a better view or rinse debris off the lining. The vet examines both the upper (squamous) and lower (glandular) portions of the stomach, since ulcers in these two areas behave differently and respond to different treatments.
You’ll typically see the screen alongside your vet and get results immediately. Ulcers are graded from 0 (healthy, intact lining) to 4 (extensive deep ulceration). Grade 1 means the tissue looks irritated but isn’t broken down yet. Grade 2 involves small lesions, grade 3 means large or widespread surface-level damage, and grade 4 is the most severe with deep erosion across a large area. The grade directly shapes the treatment plan and duration.
Is Scoping Worth It vs. Just Treating?
Many horse owners wonder whether they should skip the scope and go straight to a trial course of ulcer medication. It’s a fair question, since a month of treatment can cost $300 to $1,000 or more depending on the drug and dose. Gastroscopy is the only reliable way to definitively diagnose gastric ulcers in a living horse. No blood test or behavioral checklist can confirm ulcers with the same accuracy, which is why gastroscopy is considered the gold standard.
The case for scoping first is strongest when you want to know exactly what you’re dealing with. A scope tells you whether ulcers are present at all, where they are, and how severe they are. Squamous ulcers (in the upper stomach) and glandular ulcers (in the lower stomach) can require different treatment approaches, and you can’t distinguish between them without looking. A scope also rules out other problems that mimic ulcer symptoms, like stomach tumors or severe inflammation of the esophagus.
The case for skipping the scope comes down to practicality. If your horse has classic ulcer symptoms, your vet may suggest a treatment trial and judge by the response. This approach results in fewer diagnostic procedures and lower upfront costs. The risk is that you spend weeks and hundreds of dollars medicating a horse that either doesn’t have ulcers or has glandular ulcers that need a different protocol than the standard treatment.
A follow-up scope after treatment is also worth considering. Many vets recommend re-scoping four to six weeks into treatment to confirm healing, especially for grade 3 or 4 ulcers. That’s another round of the same costs, so factor it into your budget if your horse has significant disease.
How to Keep Costs Down
Hauling to a clinic instead of requesting a farm call saves $30 to $80 on average. If your vet offers gastroscopy days where they scope multiple horses at one barn, the farm call fee gets split among owners, which can cut your share significantly. Some equine practices run periodic “scope clinics” at a reduced per-horse rate for exactly this reason.
Ask your vet for an all-inclusive quote before scheduling. Specifically ask whether sedation and the exam fee are included or billed separately. The difference between a $250 quote and a $250-plus-sedation-plus-farm-call invoice is real, and it catches people off guard when they haven’t asked upfront.
