Urgent Care/Walk-in Billing

Learn how urgent care / walk-in billing works for different locations.  

Urgent care and walk-in services

Urgent care/walk-in services are available at multiple locations within the Mass General Brigham system.

The billing information below  does not apply  to urgent care/walk-in care services provided at centers named "Mass General Brigham Urgent Care" (formerly "Partners Urgent Care") located in Boston and surrounding communities.

How urgent care/walk-in billing may affect me

Since the locations listed below are not considered by health insurance plans to be urgent care/walk-in centers, your co-payment benefits for urgent care/walk-in services typically will not apply. Instead, your visit to these locations will likely be billed either as a physician office visit or a hospital outpatient visit.

Hospital outpatient locations  

Urgent care/walk-in services provided at the following locations are typically billed to your health insurance plan as a hospital outpatient visit:

You can find information about whether your visit is a physician office or hospital outpatient visit in notices in our waiting rooms, on this website and the websites of our hospitals and physician groups, and via in-center printed guides.

For physician office locations

Urgent care/walk-in services are typically billed as a physician or nurse practitioner visit, and your out-of-pocket costs are usually limited to the co-payment required by your health insurance plan.

We will request your co-payment when you check in for the visit.

For hospital outpatient locations

Your out-of-pocket costs for the physician or nurse practitioner visit are usually limited to the co-payment required by your health insurance plan. We will request your co-payment when you check in for the visit. 
You will also be billed for what is commonly known as a “facility fee” for use of the hospital space, equipment, and support staff.

Your health insurance plan may apply these hospital fees to your annual deductible, and after you have paid your deductible in full, you may be billed for a co-insurance payment.

We will send you a bill if there is any unpaid balance after we receive payment for your visit from your health insurance plan.

For both physician office visits and hospital outpatient visits, your health insurance plan may require you to get a referral or authorization. In addition, our providers may be considered “In Network” or “Out of Network” depending on the specifics of your health insurance plan, which could affect the amount you pay.

No matter the location, if a procedure is performed during the visit, you may have further out-of-pocket costs for additional physicians’ services and for use of the hospital facilities and staff, even if the procedure was performed in the same exam room as the visit with the physician. Your health insurance plan may apply these additional physician and hospital charges to your annual deductible, and after you have paid your deductible in full, you may be responsible for an additional co-insurance payment.

If your physician ordered laboratory tests or imaging services (such as X-ray, CT or MRI), you will be billed for these tests by the hospital, clinical laboratory, or imaging center, and you may also be billed for the services of the physicians (usually pathologists and radiologists) who interpreted the test results.

If you are a Medicare beneficiary and your visit takes place in a hospital outpatient location, you will be responsible for a Medicare Part B out-of-pocket co-insurance payment of approximately $25 for the hospital facility charge. Procedure charges or other testing could increase your out-of-pocket expenses.
