"How much does a HIDA scan cost?"

"Without insurance, $1,000–$4,000. The CCK-stimulated version that measures gallbladder ejection fraction costs more because of the added medication and longer scan time."

"Does insurance cover a HIDA scan?"

"Yes, when ordered to evaluate gallbladder function, suspected bile duct blockage, or biliary leak. You typically pay your imaging copay and coinsurance after the deductible."

"How long does a HIDA scan take?"

"Usually 1–2 hours, sometimes up to 4 if delayed images are needed. You're injected with a radioactive tracer that the liver excretes into bile, and a gamma camera tracks it."

HIDA Scan Cost: Gallbladder Function Test Pricing in 2026

📋 Data from Medicare fee schedules & FAIR Health ✓ Reviewed by board-certified gastroenterologist 🔄 Updated May 2026

You’ve had right-sided belly pain after fatty meals, your ultrasound looked normal, and your doctor says you need a HIDA scan. The first question most people ask: what’s this going to cost? The answer is $1,000 to $4,000 without insurance — and the version you get matters.

A HIDA scan (hepatobiliary iminodiacetic acid scan) is a nuclear medicine study that watches bile flow from your liver through the gallbladder and into the small intestine. A small dose of radioactive tracer is injected, and a gamma camera tracks where it goes. It diagnoses gallbladder and bile-duct problems an ultrasound or scope can miss. Here’s the cost picture.

What a HIDA Scan Costs

The plain HIDA scan is cheaper; adding CCK (a hormone that makes the gallbladder contract so its ejection fraction can be measured) pushes the price up.

Type	What It Adds	Typical Range (Uninsured)
Standard HIDA scan	Tracer + gamma camera imaging	$1,000 – $2,500
HIDA with CCK stimulation	CCK drug + extended imaging	$1,800 – $4,000
Radiologist / nuclear med interpretation	included or $150 – $400	varies

There’s no scope and no sedation here, which keeps it below a colonoscopy — but the radioactive tracer and gamma camera make it pricier than a plain X-ray-based test.

Why the CCK Version Costs More

The CCK medication. This is the hormone analog (often sincalide) that triggers gallbladder contraction, and it’s an added drug charge.
Longer scan time. Measuring the gallbladder ejection fraction means imaging before and after CCK, extending the study and the camera time.
More interpretation. Calculating the ejection fraction percentage adds analysis the standard scan doesn’t require.

The CCK-stimulated study is what diagnoses biliary dyskinesia — a poorly functioning gallbladder that looks normal on ultrasound — so the extra cost often buys the actual answer.

What a HIDA Scan Diagnoses

HIDA scans answer biliary questions other tests can’t. Gallbladder disease is extraordinarily common — the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) estimates that gallstones affect roughly 10–15% of U.S. adults. HIDA is used to:

Confirm acute cholecystitis when the gallbladder won’t fill with tracer
Measure gallbladder ejection fraction (the CCK version) for biliary dyskinesia
Detect bile leaks after gallbladder surgery
Assess bile-duct obstruction when other imaging is inconclusive

It’s frequently ordered after a normal ultrasound when symptoms strongly suggest a gallbladder problem.

Key Takeaway

A HIDA scan costs $1,000–$2,500 for the standard study and $1,800–$4,000 for the CCK-stimulated version that measures gallbladder ejection fraction. There’s no scope or sedation, so it sits below most GI procedures in cost. Insurance covers it for documented biliary symptoms, leaving you an imaging copay and coinsurance. If your doctor suspects a sluggish gallbladder rather than stones, you’ll likely need the pricier CCK version — that’s the one that gives the ejection fraction.

Insurance Coverage

HIDA scans are covered when there’s a clear biliary indication — gallbladder pain, suspected cholecystitis, post-surgical leak, or inconclusive ultrasound. As a nuclear medicine imaging study, it bills under your imaging benefit, so cost-sharing is generally a copay plus coinsurance after the deductible.

Some advanced imaging requires prior authorization, so confirm with your plan. The full uninsured price still counts toward your deductible if you haven’t met it.

Imaging facility prices vary wildly. A HIDA scan at a hospital nuclear medicine department can cost twice what a free-standing imaging or cardiology-affiliated nuclear center charges. Call ahead, ask for the cash price and the insured estimate, and confirm the facility is in-network. This single phone call can be the difference between a $1,000 and a $3,000 bill.

How It Fits Into a GI Workup

A HIDA scan usually follows an abdominal ultrasound that didn’t fully explain the symptoms. If a bile-duct stone or blockage is found, ERCP becomes the next step to actually treat it, and an endoscopic ultrasound can characterize duct and pancreatic problems in detail. For broader abdominal pain, an abdominal CT scan for GI issues covers more territory. HIDA’s niche is functional biliary information — how well the gallbladder and ducts are actually working — which the anatomy-focused tests can’t provide.

Bottom Line

A HIDA scan costs $1,000–$4,000 uninsured, with the CCK-stimulated ejection-fraction version on the higher end. It’s a non-invasive nuclear study that answers gallbladder and bile-duct questions ultrasound can’t, and insurance covers it for legitimate biliary symptoms. The biggest lever you control is the facility — prices at a free-standing center can be half a hospital’s. Make the call, confirm in-network status, and find out whether you need the standard or CCK version before you go.
