Overview

This two-page Federal Register notice (Vol. 89, No. 165) formally announces FDA's publication of the Small Entity Compliance Guide for the Mammography Quality Standards Act and Regulation Amendments. The SECG was developed in response to the March 10, 2023 Final Rule (88 FR 15126), which made the most significant changes to MQSA regulations in over 20 years. The notice identifies key regulatory areas addressed — accreditation body standards, certifying agency requirements, mammography equipment standards, quality assurance testing, clinical image quality, and breast density notification requirements. It also confirms the SECG is classified as Level 2 FDA guidance, meaning it does not establish legally enforceable rights for any person but represents FDA's current thinking on how to achieve compliance. The underlying rule became effective September 10, 2024.

How This Applies to Your Practice

The SECG is the FDA's official 'plain English' translation of the 2024 MQSA Final Rule. Where the Final Rule (88 FR 15126) is dense regulatory text, the SECG walks through each requirement in accessible language designed for small mammography facilities that may not have legal or compliance staff. MammoComply users should read the SECG alongside the Final Rule to understand the intent behind each regulatory change — particularly around breast density notification language, assessment categories, and the medical outcomes audit — before mapping those requirements to their facility's compliance documentation.

Practitioner Implications

Any facility that received the Final Rule (88 FR 15126) and found it difficult to parse should obtain and read the SECG. The SECG carries no independent legal force — it does not add requirements beyond the Final Rule — but it is the clearest statement of what FDA expects facilities to do. Because it is a Level 2 guidance, inspectors may reference it when evaluating facility compliance, making it functionally important even if technically non-binding.
