Introduction
In this blog, we’ll explain who the MDCG is, what their role involves, and why their guidance documents are essential for anyone working within the European medical device sector. We’ll also highlight some of the most important MDCG guidance documents that you should be aware of.
Who is the MDCG?
The Medical Device Coordination Group (MDCG) is a regulatory body established under Article 103 of the EU MDR. It is composed of representatives from all EU Member States and chaired by a representative of the European Commission.
While the MDCG itself does not have legislative authority, it plays a crucial advisory and coordination role in the implementation and consistent application of the MDR and IVDR across the EU.
Key functions of the MDCG include:
Providing advice to the European Commission and Member States on medical device regulation.
Supporting harmonised interpretation and application of MDR/IVDR.
Assisting with the assessment of notified bodies.
Developing and endorsing guidance documents to clarify regulatory expectations.
Why Are MDCG Guidance Documents Important?
The MDR and IVDR are detailed and ambitious regulations, but like any legal text, they can leave room for interpretation. That’s where the MDCG comes in. Their guidance documents are designed to provide clarity, consistency, and practical advice for manufacturers, authorised representatives, importers, notified bodies, and regulators.
Some key benefits of MDCG guidance documents include:
Interpretation Support: They help bridge the gap between legal text and practical implementation.
Harmonisation: Ensure uniform application across all EU Member States.
Compliance Assurance: Provide insights that help manufacturers and economic operators stay compliant with evolving regulatory expectations.
Up-to-date Information: Address ongoing challenges and regulatory updates in real time.
How to Find MDCG Guidance Documents
All published MDCG guidance documents are available for free on the European Commission’s medical devices website.
Each document is coded as MDCG Year-Number, for example, MDCG 2021-24.
Key Categories of MDCG Guidance Documents
There are over 100 MDCG guidance documents published to date, covering a wide range of topics. Here are some of the key categories:
1. Clinical Evaluation and Investigation
These documents help manufacturers and notified bodies interpret requirements for clinical evidence under MDR.
Examples:
MDCG 2020-13: Clinical Evaluation Assessment Report (CEAR) template.
MDCG 2020-6: Guidance on Sufficient Clinical Evidence for Legacy Devices.
MDCG 2023-7: Guidance on exemptions from the requirement to perform clinical investigations pursuant to Article 61(4)-(6) MDR and on sufficient levels of access’ to data needed to justify claims of equivalence.
2. Post-Market Surveillance (PMS) and Vigilance
MDCG provides detailed templates and procedures to streamline PMS and vigilance activities.
Examples:
MDCG 2023-3: Questions and Answers on vigilance terms and concepts as outlined in the Regulation (EU) 2017/745 on medical devices and Regulation (EU) 2017/746
MDCG 2022-21 Guidance on Periodic Safety Update Report (PSUR) according to Regulation (EU) 2017/745.
MDCG 2024-1: Device Specific Vigilance Guidance (DSVG) Template
3. UDI and EUDAMED
The Unique Device Identification (UDI) system and the European Database on Medical Devices (EUDAMED) are critical to traceability and transparency.
Examples:
MDCG 2018-1: Guidance on Basic UDI-DI and changes to UDI.
MDCG 2021-13: Questions and answers on obligations and related rules for the registration in EUDAMED of actors other than manufacturers, authorised representatives and importers subject to the obligations of Article 31 MDR and Article 28 IVDR
4. Notified Bodies and Conformity Assessment
Essential for understanding how notified bodies operate under MDR and IVDR.
Examples:
MDCG 2019-6 Rev. 5: Questions & Answers for Notified Bodies.
MDCG 2022-4 Rev. 2: Guidance on appropriate surveillance regarding the transitional provisions under Article 120 of the MDR with regard to devices covered by certificates according to the MDD or the AIMDD
5. Software and Artificial Intelligence
Software as a Medical Device (SaMD) is a growing area, and MDCG provides guidance to help determine classification and conformity.
Examples:
MDCG 2019-11: Qualification and Classification of Software.
MDCG 2019-16: Guidance on cybersecurity for medical devices
6. Borderline and Classification
These documents assist in the interpretation of classification rules, especially for borderline cases.
Examples:
MDCG 2021-24: Guidance on classification of medical devices.
MDCG 2022-5 Rev.1: Guidance on borderline between medical devices and medicinal products under Regulation (EU) 2017/745 on medical devices.
Why You Can’t Ignore MDCG Guidance Documents
Even though MDCG guidance is technically non-binding, notified bodies and competent authorities expect manufacturers to follow them as best practice. Failure to align with MDCG guidance could result in:
Non-compliant technical documentation.
Delays in CE marking.
Rejection during conformity assessments.
Product recalls or vigilance issues post-market.
In short, regulatory success in the EU depends heavily on your awareness and application of relevant MDCG documents.

Frequently Asked Questions (FAQs)
No, MDCG guidance documents are not legally binding. However, they are widely regarded as authoritative interpretations of the MDR and IVDR. Notified bodies and competent authorities expect manufacturers to align with them, and deviating from the guidance may require strong justification during conformity assessments.
MDCG guidance documents are updated as needed—typically in response to regulatory developments, implementation challenges, or emerging technologies. It’s important to regularly check the European Commission’s website or work with a regulatory partner like Patient Guard to stay informed about new or revised guidance.
Yes, several MDCG documents specifically address legacy devices that were CE marked under the Medical Devices Directive (MDD) or Active Implantable Medical Devices Directive (AIMDD) and are transitioning to MDR compliance. For example, MDCG 2020-6 and MDCG 2022-14 provide guidance on how to manage clinical evidence and transitional provisions for these devices.
The relevance of an MDCG document depends on your device type, classification, and regulatory status (e.g., legacy or MDR-compliant). Start by identifying your device’s risk class and intended use, then search for MDCG documents related to that area—such as clinical evaluation, software, or PMS. Patient Guard can help assess which guidance documents apply to your specific situation.
