Mammogram Cost in San Francisco, CA (2026): Average Prices & What You'll Pay

What does a mammogram cost in San Francisco, CA?

Where you have a mammogram done in San Francisco, CA swings the bill from $157 to $401 for identical care. The median cash price across 22 reporting hospitals is $369. The numbers are pulled directly from federally mandated hospital price transparency files.

San Francisco, CA Mammogram prices by facility

All prices below come from hospital chargemasters — the official price lists each hospital must publish under federal law. Gross charge is the undiscounted list price; cash price is the self-pay rate; negotiated range covers the spread across insurance contracts.

How we calculate "Your Price" — We prioritize the most actionable price in this order:
  1. Cash price — the self-pay rate you can actually negotiate and pay
  2. Negotiated rate — if reported by the hospital across insurance contracts
  3. Gross charge — fallback only; this is the inflated list price few people pay

This reflects the real prices patients encounter — not inflated chargemaster rates.

How to choose a lower-cost facility

  • Choose independent outpatient centers when possible — freestanding ASCs (ambulatory surgical centers) consistently charge less than hospital outpatient departments for identical procedures.
  • Ask for the cash price if your deductible isn't met — self-pay rates are often lower than what insurance pays before your deductible is satisfied, especially at facilities that have a high cash-price discount.
  • Avoid hospital outpatient departments for routine cases — hospital-owned locations add a facility fee that freestanding centers don't charge, often adding $500–$1,500 to the same procedure.
Important: Many procedures are done at ambulatory surgical centers (ASCs) that are often 30–60% cheaper than hospital outpatient departments with the same clinical quality. Most ASCs are not in this hospital dataset — meaning your cheapest option may not even appear here. Ask your doctor if the procedure can be done at a freestanding ASC.

Why prices vary this much

Setting drives much of the gap in San Francisco, CA: the median outpatient price is $369 versus $304 inpatient, so where a procedure is performed often matters more than which hospital you choose. Of the San Francisco, CA facilities reporting prices, 6 fall in a low-cost tier (up to $122) while 10 sit in a high-cost tier ($401 and up) — a lower-priced option almost always exists within the same state.

Among the cities with the most reporting hospitals, Oakland has a median reported price of $401 across 3 facilities, while facilities in Concord tend to report lower prices (median: $304). City-level variation within a state often reflects local market structure, not procedure complexity.

The spread comes from how each hospital sets its chargemaster (the undiscounted list price), what cash discounts it applies, and what rates it negotiates with each insurer. Facility classification matters too — a hospital-owned outpatient center adds a facility fee that a freestanding clinic does not. Understanding these mechanics is the first step to paying less.

How insurance changes what you actually pay

Hospital list prices are only part of the picture. What you pay out of pocket depends on your deductible, your plan's out-of-pocket maximum, whether the facility is in-network, and whether your plan classifies the visit as outpatient or inpatient. A lower gross charge doesn't guarantee a lower bill if the facility is out-of-network or adds facility fees your plan doesn't cover.

Where You Get a Mammogram Matters

Hospital outpatient departments typically charge 2–4× more than ASCs or independent centers for the same procedure — same outcome, very different bill.

Hospital Outpatient Department

Hospital Outpatient Department typically carries a higher price for a mammogram. Facility fee billed separately from professional fee. Provider-based billing adds facility overhead. You can shop here — call ahead and ask for a self-pay or cash quote.

Independent Imaging Center

Independent Imaging Center typically carries the lowest typical price for a mammogram. Freestanding radiology centers. Technical component billed by center; professional (radiologist read) billed separately. You can shop here — call ahead and ask for a self-pay or cash quote.

Emergency Room Mammogram

A Mammogram performed in the emergency department can run 2–5× the cost of the identical scan at an outpatient or independent facility, because a hospital facility fee stacks on top. Use the ER only when the situation is medically urgent — it is not a setting where you can shop on price.

Mammogram Cost by Type

Which type your doctor orders changes the billing code — and what you pay. Here's how the common types differ.

Screening Mammogram (2D)

Billed as preventive care — often covered at $0 under the ACA when you are average-risk and in-network. Preventive; $0 cost-share on ACA-compliant plans (CPT 77067).

Screening Mammogram (3D / tomosynthesis)

Billed as preventive care — often covered at $0 under the ACA when you are average-risk and in-network. CPT 77063 add-on / 77067; some plans cover at $0, others apply the 3D add-on.

Diagnostic Mammogram

Ordered to investigate symptoms or a prior finding — standard cost-sharing (deductible, coinsurance) applies. Ordered to evaluate a symptom or follow up a screening finding (CPT 77065/77066). Cost-sharing applies.

Covered at $0 — But Only If It Stays a Screening

Under the ACA (§2713), preventive services — including mammogram for average-risk adults — must be covered at $0 with no cost-sharing when performed by an in-network provider.

The risk: A screening mammogram is covered at $0 under the ACA. If a finding requires additional views or ultrasound, it converts to a diagnostic mammogram and cost-sharing applies — the single most common mammogram billing surprise.

This Procedure Is Shoppable — Choosing the Right Facility Can Save Thousands

Mammogram is elective and schedulable. You have time to compare facilities — and hospital outpatient prices often run 2–4× higher than Hospital OP, Imaging Center for identical clinical outcomes.

How to shop: Ask your doctor for the CPT code, then call 2–3 facilities and request an out-of-pocket cost estimate. Confirm your insurance is accepted. If uninsured, ask for the cash-pay rate — it's usually 20–50% below the list price.

Who performs this: Mammogram is typically performed by a Radiology. The specialist's professional fee is billed separately from the facility charge — you will likely receive separate bills from each.
