A CT scan (computed tomography, sometimes called a CAT scan) combines a rotating X-ray beam with a detector and computer reconstruction to build cross-sectional images of the body. CT is fast — a head or chest study can be completed in a few minutes — and is the imaging workhorse of emergency departments for trauma, stroke, chest pain, and abdominal pain. Many CT studies use an intravenous iodinated contrast agent, and some (CT colonography, CT enterography) also use oral contrast. CT delivers a meaningful dose of ionizing radiation, which is why clinicians balance the study's diagnostic value against radiation exposure, particularly in younger patients. The cost varies substantially based on body region, the use of contrast, and whether the study is performed at a hospital outpatient department or a freestanding imaging center.
비용에 영향을 미치는 요소
- Site of service: hospital outpatient facility fees add significant cost; freestanding imaging centers are typically 30–60% cheaper for the same CPT code.
- Body region imaged: head/brain, chest, abdomen, pelvis, and combined studies each have different base rates.
- With or without contrast: contrast studies add an ancillary drug charge and a separate CPT code.
- Multi-phase studies: triple-phase liver or renal CT protocols are billed differently than single-phase studies.
- Whether CT angiography (CTA) is used: CTA of the chest, abdomen, or brain is billed at higher CPT codes than routine CT.
- Radiologist professional fee: sometimes billed separately from the technical fee, especially at hospital-owned sites.
절약 방법
- Request a freestanding imaging center when clinically appropriate rather than hospital outpatient imaging.
- Ask for the cash/self-pay price — it is frequently a fraction of the chargemaster rate and sometimes below the insured rate before deductible.
- Confirm prior authorization in advance; unauthorized CT studies are frequently denied and billed to you directly.
- For non-urgent indications, ask whether an alternative study (ultrasound or MRI) could answer the clinical question with equal or greater diagnostic value.
- Use your insurer's cost estimator tool — CT prices within a single metro area can vary 3–5x.
- Verify that the facility is in-network and that the radiologist reading the study is in-network as well.
보험 및 보장 참고사항
Most commercial plans, Medicare Part B, and Medicaid cover CT when medically necessary. Commercial plans typically require prior authorization via a radiology benefit manager. Under Medicare, the typical patient cost is 20% coinsurance after the Part B deductible; commercial plans vary by plan design. Emergency CT studies performed during an ER visit are covered under the No Surprises Act for any plan that covers emergency services. If you are paying without insurance, request the Good Faith Estimate required under the No Surprises Act before the appointment.
