Mammography Quality Standards Act and Program

The FDA issued a Small Entity Compliance Guide to help small entities understand, in plain language, a rule issued on March 10, 2023, amending the Mammography Quality Standards Act (MQSA) and its implementing regulations (“2023 MQSA Rule”). The information contained in the SECG is also intended to replace the Policy Guidance Help System, which will be discontinued on September 10, 2024.

On March 10, 2023, the FDA issued the Final Rule to Amend the MQSA Regulations. These updated requirements are to be implemented by mammography facilities within 18 months after publication in the Federal Register. Facilities are not prohibited from including the required breast density notification before 18 months; however, facilities subject to the MQSA must comply with all the requirements, including the breast density notification, no later than September 10, 2024.

On January 12, 2024, the Division of Mammography Quality Standards posted "Important Information: Final Rule to Amend the Mammography Quality Standards Act (MQSA)" to assist facilities in preparing for annual MQSA inspections and to provide additional information regarding the rule amendments. The information on this webpage will be updated as additional information becomes available.

The Mammography Quality Standards Act (MQSA) became law on Oct. 27, 1992. Congress enacted the MQSA to ensure that all people have access to quality mammography for the detection of breast cancer in its earliest, most treatable stages.
