Is a Mammogram Covered by Insurance? (2026 Guide)
Yes - and for routine screening mammograms, "covered" means $0 out-of-pocket in-network. The ACA and HRSA Women's Preventive Services Guidelines require ACA-compliant plans to cover screening mammograms with no cost sharing at all. Diagnostic mammograms work differently: they run through your deductible and coinsurance.
Quick answer:
- Screening mammogram (age 40+, in-network): $0 - no copay, no deductible
- Diagnostic mammogram (evaluating a symptom or abnormal finding): Deductible + coinsurance
- Additional imaging after an abnormal screening (starting 2026): $0 on ACA plans
- Prior authorization: Not required for preventive screening
Before You Schedule: Ask These 5 Questions
Use these questions before the appointment, not after the EOB arrives:
| Ask | Why it matters |
|---|---|
| "Is this being ordered as screening or diagnostic?" | Screening is usually $0; diagnostic care may run through deductible and coinsurance |
| "Is the facility in-network with my exact plan?" | A covered mammogram can still cost more at an out-of-network site |
| "Is 3D tomosynthesis included or billed separately?" | Some plans cover 3D at $0; others apply cost-sharing or require a different billing code |
| "If I need extra views during the visit, will the claim change?" | A callback or same-day additional image can shift the visit from preventive to diagnostic |
| "Will the radiologist bill separately?" | A second professional claim can arrive after the facility claim |
If you are comparing facilities, ask for the billing location too. Hospital outpatient departments can attach a different facility charge than an independent breast imaging center, even when the scan itself is clinically similar.
A screening mammogram is $0 - until a callback or a symptom re-codes it as diagnostic and the bills start.
Your personalized cost report includes:
- ✓ When a "free" screening becomes a cost-shared diagnostic mammogram - and how to see it coming
- ✓ The separate radiologist bill most patients miss (and how to verify it's in-network)
- ✓ Why a hospital outpatient department can cost far more than a breast center for the identical study
- ✓ When 3D tomosynthesis adds a separate charge - and the questions to ask before you schedule
- ✓ A real patient billing breakdown, line by line

Screening vs. Diagnostic: The Core Distinction
A screening mammogram is a routine preventive scan ordered for women without symptoms. Under HRSA guidelines (2026), screening is covered at $0 beginning at age 40 for average-risk women, either annually or biennially.
A diagnostic mammogram is ordered to evaluate a specific concern - a lump you felt, nipple discharge, breast pain, or an abnormal finding on a prior screening. Diagnostic mammograms are covered as medical services, not preventive care, so your plan's cost sharing applies: deductible first, then coinsurance.
The trap: If the radiologist needs extra views during a routine screening appointment, they may reclassify the visit as diagnostic mid-appointment. That converts a $0 visit to a cost-sharing event. You often don't know until the EOB arrives.
Why a "Free" Mammogram Can Still Create a Bill
Most surprise mammogram bills come from one of four situations:
| Situation | Why a bill appears | What to check |
|---|---|---|
| Callback imaging | The second visit is treated as diagnostic | Whether your plan or state requires $0 follow-up imaging |
| Symptoms on the order | The claim starts as diagnostic, not preventive | The diagnosis code and reason for the order |
| 3D mammography add-on | Tomosynthesis may be a separate line item | Whether the 3D CPT/revenue code is preventive under your plan |
| Separate radiologist claim | The interpretation bills separately | Whether the radiology group is in-network |
The most useful document after the visit is the EOB. If the EOB says you owe more than expected, compare the claim type, diagnosis code, allowed amount, deductible applied, and patient responsibility before paying the provider bill.
2026 Update: Additional Imaging After an Abnormal Screening
Starting with plan years beginning in 2026, ACA-compliant plans must cover additional breast imaging or pathology ordered after an abnormal screening result with no cost sharing. This means:
- A screening mammogram that triggers an ultrasound or breast MRI → the follow-up imaging is also $0
- Biopsy ordered following an abnormal screening → covered as part of the preventive cascade
This rule applies to in-network providers on non-grandfathered individual and small-group plans. Self-insured employer plans are exempt.
State Mandates: Where Diagnostic Mammograms Are Also $0
More than 20 states require fully-insured plans to cover diagnostic mammograms and supplemental breast imaging (ultrasound for dense breasts, breast MRI for high risk) with no cost sharing. If you're in one of these states, your diagnostic mammogram may also be free:
$0 diagnostic coverage states (state-regulated fully-insured plans): AL, AK, AR, CO, CT, FL, GA, ID, IL, KY, LA, ME, MA, MS, MO, MT, NM, NY, OK, OR, TN, TX, VT, VA, WA
Supplemental imaging coverage (dense breasts / high risk): NV, NH, PA, DC
Note: Self-insured employer plans (ERISA-governed) are not subject to state mandates - federal ERISA preempts state insurance law.
What Bills to Expect
| Bill | Who sends it | Notes |
|---|---|---|
| Technical fee | Imaging center or hospital | Equipment and mammography technologist |
| Professional fee | Radiologist | Reading and interpretation |
| Supplemental imaging fee | Imaging center | If breast ultrasound or MRI ordered |
If a Mammogram Bill Arrives
Do this in order:
- Wait for the EOB before paying the provider bill.
- Confirm whether the claim says screening, diagnostic, or follow-up imaging.
- Check whether any 3D/tomosynthesis charge was separate from the base mammogram.
- Compare the EOB patient responsibility to the amount on the bill.
- Call the insurer first if preventive care appears to have been processed with deductible or coinsurance.
