California Medicare physician rate (2026)

What the whole procedure costs
The office rate above is what an imaging center, lab or office is paid for the whole test. In a hospital, the facility bills its own fee and the physician bills only the reading. These are 2026 national Medicare amounts.
Medicare may pay the facility separately for this code or package it into another service on the same day, so treat the facility share as an upper bound. For a test like this the physician in a hospital bills only the reading (the professional component); outside a hospital one global fee covers the whole test, shown in the office rate above. Medicare allowed amounts are not what an uninsured patient is charged, and not a quote. Private plans typically allow more.

What these numbers are
Every figure on this page is a 2026 Medicare allowed amount: the physician line comes from the Physician Fee Schedule adjusted by geographic practice-cost indices, and the facility totals come from the CMS hospital outpatient (OPPS) and ambulatory surgery center rates. None of them is a hospital chargemaster price, your insurer's contracted rate, or a quote. Anesthesia, pathology, imaging reads and follow-up care are billed under their own codes when they apply, and an inpatient stay is paid a different way again. In California the office and hospital physician lines for this CPT differ by $79.23.

CT Head Without Contrast and how California is priced
California is the most finely divided state in the Medicare fee schedule, with roughly thirty payment localities drawn around metropolitan statistical areas after CMS reformed the state's locality map. The San Francisco Bay Area carries some of the highest geographic adjustments in the nation, with San Francisco, San Jose, and the East Bay each priced separately, while Los Angeles, Orange County, San Diego, and Sacramento have their own localities at somewhat lower levels. Rural and inland counties fall into lower-cost localities, so the same procedure can carry meaningfully different Medicare-approved amounts within a single day's drive. No other state shows this much in-state variation on the fee schedule itself.
California's markets differ sharply: the Bay Area combines high wages with heavily consolidated hospital systems, Los Angeles offers enormous choice across a sprawling region, and the Central Valley and far north face genuine access shortages. Where you are treated within the state matters more here than almost anywhere else in the country. Academic medical centers in the Bay Area, Los Angeles, San Diego, and Sacramento handle much of the complex referral care.
This procedure: A CT scan of the head without contrast uses X-rays and a computer to build cross-sectional pictures of the brain and skull. It is the usual first scan after a head injury, a sudden severe headache, or symptoms that could be a stroke, because it is fast and shows bleeding and fractures clearly. The scan itself takes only a few minutes: you lie on a table that slides through a ring-shaped scanner, and no injection is involved in this non-contrast version.
What Is CT Head Without Contrast?
A CT scan of the head without contrast uses X-rays and a computer to build cross-sectional pictures of the brain and skull. It is the usual first scan after a head injury, a sudden severe headache, or symptoms that could be a stroke, because it is fast and shows bleeding and fractures clearly. The scan itself takes only a few minutes: you lie on a table that slides through a ring-shaped scanner, and no injection is involved in this non-contrast version.
What Affects the Cost
- –Where the scan is done matters most: a hospital outpatient department or emergency room adds a facility payment that is often far higher than what a freestanding imaging center charges for the same scan.
- –A head CT done in the emergency department is billed alongside an ER visit level, which usually costs more than the CT itself.
- –In a hospital, the radiologist's reading is billed separately from the scan, often by a physician group you never meet.
- –If contrast is added, the study becomes a different and costlier code (70460, or 70470 for a scan without and then with contrast) and the contrast agent is charged as well.
- –Freestanding imaging centers often publish cash prices well below a hospital's list price, so it is worth asking when the scan is not urgent.
Questions to Ask Before Booking
- 1.Is a CT the right test for my symptoms, or would an MRI or no scan at all be better?
- 2.Can the scan be done at a freestanding imaging center instead of the hospital?
- 3.Does my plan need prior authorization, and has it been approved?
- 4.Is the radiologist's reading included in the price, or billed separately?
- 5.Will contrast be used, and how would that change the cost?

After the Part B deductible, coinsurance is usually 20% of the allowed amount: about $24 for the office physician line or $8 for the hospital physician line in California. Medigap may cover that 20%. This is not the hospital facility fee.
It depends on where the test is done. At an independent imaging center, lab or office, $120.71 is Medicare's full rate in California, covering the test and the reading. In a hospital outpatient department the physician is paid only for the reading (about $41.48) and the hospital is paid separately, which brings the national total to up to about $146. California ranks #49 of 51 states on the non-hospital rate (13% above the national office rate of $106.55).
