Compare the bill with the estimate
Open CMS’s current screening instructions and check your insurance use, service date, estimate timing and initial bill date. The process addresses uninsured or self-pay care. It is separate from asking an insurer to reverse a denied claim. Ask the CMS Help Desk about an unclear screening condition before assuming your situation qualifies.
CMS uses a difference of at least $400 for one provider or facility compared with that provider’s estimate. Identify the matching provider and services instead of combining unrelated bills. Record the date on the initial bill: the current form screens for a bill dated within the last 120 calendar days.

Complete the patient and service details
The form asks for the patient’s name, contact information, state and date of service, and a short description of the disputed item or service. It provides fields for an authorized representative when applicable. Confirm who should receive contact about the request and complete those fields accurately.
Attach readable copies of the disputed bill and good faith estimate. Add the provider’s contact details where requested. Keep the originals and retain a copy of the completed packet. If a detail is missing, ask the billing office for the specific item rather than replacing it with an estimate of your own.

Read the authorization and arrange the fee
Before signing, read the form’s permission for relevant medical or treatment records to go to the selected dispute reviewer. The signature also covers the fee and the payment determined through the process. Ask the Help Desk to explain any part you do not understand.
CMS currently requires a $25 non-refundable administrative fee, and the process does not start until it is paid. Follow the official payment instructions. The form permits a cashier’s check or money order with a mailed packet and describes an electronic payment link after receipt; cash and personal checks are not accepted.

Use the current form’s destination and track the response
Start from the CMS dispute page or its current form. For mail, the form names StrategyGen Co., Patient-Provider Dispute Resolution, 50 N. Laura Street, Ste 2500, Jacksonville, FL 32202. Its final page also supplies the fax route. Copy the current instructions when sending and save dated confirmation.
The selected reviewer may request missing information. CMS’s decision tree describes a 21-calendar-day response period; read the actual notice and respond through its instructions. Keep that notice, your response and the final decision together. If the provider offers a settlement during review, ensure the reviewer is informed through the official process.

Common questions
What if I did not receive a good faith estimate?
CMS provides a complaint route when an estimate should have been supplied. Contact its Help Desk or follow the official action-plan guidance; do not create a replacement estimate to fit the dispute form.

Does the application guarantee that the bill will match the estimate?
No. An independent reviewer determines the appropriate payment. CMS explains that some additional costs can remain justified; submitting a dispute does not establish that every charge must be removed.
