MDCG 2019-11 Rev.1: Important Changes for Medical Device Software Developers

In the dynamic world of medical device regulation, staying abreast of the latest guidance is paramount for manufacturers. The Medical Device Coordination Group (MDCG) has recently released a significant update to its MDCG 2019-11 guidance document, now designated as MDCG 2019-11 Rev.1. This revised document, published in June 2025, provides clarifications and expanded insights into the qualification and classification of Medical Device Software (MDSW) under the Medical Device Regulation (EU) 2017/745 (MDR) and the In Vitro Diagnostic Medical Device Regulation (EU) 2017/746 (IVDR).

Understanding the Core Purpose

The MDCG 2019-11 Rev.1 guidance is primarily aimed at MDSW manufacturers, offering a comprehensive framework for navigating the complexities of regulatory compliance. It delineates the criteria for qualifying software within the scope of the MDR and IVDR, including Medical Device Artificial Intelligence (MDAI). Furthermore, it provides detailed instructions on applying the classification criteria to MDSW and offers essential information regarding placing MDSW on the market. A key takeaway from this updated guidance is the emphasis on the 'intended purpose' of the software, irrespective of its location or platform (e.g., mobile, cloud). The previous term 'standalone software' is no longer used, underscoring a shift towards a function-centric regulatory approach.

Key Revisions and Their Implications

The Rev.1 update introduces several important changes and clarifications that professionals in the medical device industry should be aware of:

• Scope Clarification and Intended Purpose: The revised guidance places a heightened emphasis on crafting a clear and unambiguous intended purpose for MDSW. This is critical for accurate qualification and classification, preventing misinterpretations that could lead to non-compliance and market access challenges. The document also introduces considerations for modular MDSW.
• Expanded Examples and Annex XVI Software: New examples have been added to illustrate the qualification and classification process, including MDSW intended for treatment. There are also clarifications regarding the scope of the document concerning Annex XVI software, which pertains to certain products without an intended medical purpose but with similar characteristics to medical devices.
• Refined Classification Rules: Specific clarifications have been made to Rule 11 (Subrule a) of the classification rules, particularly concerning devices intended to prevent the risk of illness. This provides more precise guidance for manufacturers whose software falls under this category.
• Elaboration on 'Modules': The concept of 'Modules' within MDSW has been further elaborated upon, offering more detailed guidance on how different software components or functionalities should be considered in the qualification and classification process.
• Interplay with European Health Data Space: A significant update in Annex I (c.1) reflects the interplay between the MDSW regulations and the European Health Data Space Regulation, particularly concerning Electronic Health Record (EHR) Systems. This highlights the growing importance of data interoperability and security in the regulatory landscape.
• New Class I Example: Annex IV now includes a new example for Class I medical devices, providing practical illustration for manufacturers.

Conclusion

MDCG 2019-11 Rev.1 serves as a vital resource for manufacturers navigating the complex regulatory environment of medical device software in the EU. The updates underscore the European Commission's commitment to ensuring the safety and performance of MDSW, while also adapting to technological advancements such as AI and modular software. By understanding and implementing these revised guidelines, manufacturers can ensure compliance, streamline their market access strategies, and ultimately contribute to better patient outcomes. Staying informed about these regulatory nuances is not just a matter of compliance, but a strategic imperative for success in the evolving digital health sector.
