Special 510(k) [All terms](/terms) Regulatory [Regulated Pathways](/ecosystems/regulated-pathways)Special 510(k) # Special 510(k) Streamlined 510(k) for modifications to a manufacturer's own legally marketed device. Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 5, 2026 ## Definition A Special 510(k) relies on design control procedures to support a determination of [substantial equivalence](/terms/substantial-equivalence) for changes to the submitter's own predicate, with a target FDA review goal of 30 days. What the regulation says The FDA introduced the Special 510(k) to streamline the review process for modifications to a manufacturer's own previously cleared device. This submission type assumes the changes can be adequately evaluated through design control procedures, as outlined in 21 CFR 820.30, without raising new questions of safety and effectiveness. It is intended for changes that do not alter the fundamental technology or [intended use](/terms/intended-use), focusing on modifications verifiable through established performance data. ## What this means in practice Best when the modification's effects can be assessed via verification and validation methods with well-established performance criteria. Not appropriate for changes to [indications for use](/terms/indications-for-use). ## Examples - A manufacturer updates the software of a cleared infusion pump to improve the user interface without changing the essential performance or safety algorithms, submitting a Special 510(k) supported by software verification and validation documentation. - A company modifies the material of a component in a cleared surgical instrument to enhance durability, demonstrating equivalence through material testing and biocompatibility data via a Special 510(k). - A MedTech firm makes a minor dimensional change to a cleared orthopedic implant that does not affect its fit or function, submitting a Special 510(k) with engineering analyses and test results. Common pitfalls - • A common pitfall is submitting a Special 510(k) for changes that significantly alter the device's technology or intended use, leading to a rejection or a request for a Traditional 510(k). - • Misjudging the appropriate level of verification and validation needed for the modification can result in an incomplete submission. - • Failing to clearly document the link between the design changes and the supporting verification and validation activities is a frequent mistake. - • Assuming a 30-day review timeline is guaranteed, as the actual review time can be longer if deficiencies are identified. - • Submitting a Special 510(k) for modifications that introduce new risks or significantly impact patient safety is inappropriate and will be rejected. ## Frequently asked questions When is a Special 510(k) appropriate? A Special 510(k) is appropriate for modifications to your own cleared device where the changes can be assessed through [design controls](/terms/design-controls) and established performance criteria, such as material changes, sterility changes, or software enhancements that do not alter the [indications for use](/terms/indications-for-use). What is the primary benefit of a Special 510(k)? Can a Special 510(k) be used for changes to indications for use? ## Cross-references ### Part of A larger framework or document this term belongs to. - [ 510(k) Premarket Notification(510(k)) ](/terms/510k) ## Related terms Grouped by theme ### Editor's picks · Hand-selected related concepts [ Regulatory 510(k) Premarket Notification(510(k)) FDA submission demonstrating a device is substantially equivalent to a legally marketed predicate. ](/terms/510k)[ Regulatory Abbreviated 510(k) 510(k) variant that relies on FDA guidance, special controls, or recognized consensus standards. ](/terms/abbreviated-510k)[ Quality & Risk Design Controls Structured process governing the design of medical devices. ](/terms/design-controls) ### More in Regulatory · Same category [ Regulatory 510(k) Summary vs 510(k) Statement Two alternative disclosure mechanisms in a 510(k) submission, a Summary is public on FDA's website; a Statement promises to share Safety & Effectiveness info on request. ](/terms/510k-summary-vs-statement)[ Regulatory 513(g) Request for Information(513(g)) Formal mechanism to ask FDA whether a product is a device and, if so, its likely classification. ](/terms/513g)[ Regulatory Accreditation Scheme for Conformity Assessment(ASCA) FDA voluntary program in which accredited testing labs perform standards-based testing accepted with reduced FDA scrutiny. ](/terms/asca)[ Regulatory Additional Condition for Nonprescription Use(ACNU) FDA's 2024 final rule creating a pathway for nonprescription drug products that rely on additional conditions (e.g., self-selection tools, drug-device combinations) to ensure safe use without a healthcare provider. ](/terms/acnu) Cited by Where this term appears across MedTech Terms.
