[Docket No. FDA-2023-N-4372]


Medical Devices; Exemptions From Premarket Notification: Class II 
Devices; Clinical Electronic Thermometers

AGENCY: Food and Drug Administration, HHS.

ACTION: Final amendment; final Order.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA, we, or the Agency) is 
publishing an order setting forth the Agency's final determination to 
exempt certain class II clinical electronic thermometers from premarket 
notification (510(k)) requirements, subject to certain limitations. 
This exemption from 510(k), subject to certain limitations, is 
immediately in effect for such class II clinical electronic 
thermometers. This exemption will decrease regulatory burdens on the 
medical device industry and will eliminate private costs and 
expenditures required to comply with Federal regulations. FDA is 
amending the classification language within the Code of Federal 
Regulations for certain class II clinical electronic thermometers to 
reflect this final determination. FDA is publishing this order in 
accordance with the Federal Food, Drug, and Cosmetic Act (FD&C Act).

DATES: This order is effective June 18, 2025.

SUPPLEMENTARY INFORMATION:

I. Background

    Under section 510(k) of the FD&C Act (21 U.S.C. 360(k)) and its 
implementing regulations in part 807, subpart E (21 CFR part 807, 
subpart E), persons who propose to begin the introduction or delivery 
for introduction into interstate commerce for commercial distribution 
of a device intended for human use are required to submit a premarket 
notification to FDA. The device may not be marketed until FDA finds it 
``substantially equivalent'' within the meaning of section 513(i) of 
the FD&C Act (21 U.S.C. 360c(i)) to a legally marketed device that does 
not require premarket approval.
    The 21st Century Cures Act (Cures Act) (Pub. L. 114-255) was signed 
into law on December 13, 2016. Section 3054 of the Cures Act amended 
section 510(m) of the FD&C Act. As amended, section 510(m)(1) of the 
FD&C Act requires that within 90 days of the date of enactment of the 
Cures Act, and at least once every 5 years thereafter (as FDA 
determines appropriate), FDA publish in the Federal Register a notice 
containing a list of each type of class II device that FDA determines 
no longer requires a report under section 510(k) of the FD&C Act to 
provide reasonable assurance of safety and effectiveness. FDA must 
provide at least a 60-day comment period for any such notice prior to 
issuing a final determination with respect to the devices contained in 
the list. Additionally, section 510(m)(2) of the FD&C Act provides that 
FDA may exempt a class II device from the requirement to submit a 
report under section 510(k) of the FD&C Act, upon its own initiative or 
a petition of an interested person, if FDA determines that a 510(k) is 
not necessary to provide reasonable assurance of the safety and 
effectiveness of the device. FDA must publish in the Federal Register a 
notice of intent to exempt a device, or of the petition, and provide a 
60-day comment period.
    In the Federal Register of November 3, 2023 (88 FR 75602), FDA 
published a notice announcing its intent to exempt certain class II 
clinical electronic thermometers from premarket notification (510(k)) 
requirements, subject to certain limitations, and provided 60 days for 
interested persons to submit comments by January 2, 2024. Although FDA 
received no comments to the docket following a 60-day comment period, 
FDA is making minor modifications to clarify the limitations on 
exemption (see section III. B. Partial Limitations of Exemptions). 
Additionally, we provide examples to help clarify the first two partial 
limitations of exemption (see section III. B. Partial Limitations of 
Exemptions). This final order sets forth our final determination to 
exempt certain class II clinical electronic thermometers that were the 
subject of the notice. Through this action, FDA is now amending the 
language for the identified classification regulation (21 CFR 
880.2910(b)) to reflect this final determination.\1\
---------------------------------------------------------------------------

    \1\ FDA notes that the ``ACTION'' caption for this final order 
is styled as ``Final amendment; final order,'' rather than ``Final 
order.'' Beginning in December 2019, this editorial change was made 
to indicate that the document ``amends'' the Code of Federal 
Regulations. The change was made in accordance with the Office of 
Federal Register's (OFR) interpretations of the Federal Register Act 
(44 U.S.C. chapter 15), its implementing regulations (1 CFR 5.9 and 
parts 21 and 22), and the Document Drafting Handbook.
---------------------------------------------------------------------------

    This final order is expected to result in decreased regulatory 
burdens and is considered an E.O. 14192 deregulatory action.

II. Criteria for Exemption

    There are a number of factors FDA may consider to determine whether 
a premarket notification (510(k)) is necessary to provide reasonable 
assurance of the safety and effectiveness of a class II device. These 
factors are discussed in the January 21, 1998, Federal Register notice 
(63 FR 3142) and subsequently in the guidance the Agency issued on 
February 19, 1998, entitled ``Procedures for Class II Device Exemptions 
from Premarket Notification, Guidance for Industry and CDRH Staff'' 
(``Class II 510(k) Exemption Guidance'') (available at https://www.fda.gov/regulatory-information/search-fda-guidance-documents/procedures-class-ii-device-exemptions-premarket-notification-guidance-industry-and-cdrh-staff). Accordingly, FDA generally considers the 
following factors to determine whether premarket notification is 
necessary for class II devices: (1) the device does not have a 
significant history of false or misleading claims or of risks 
associated with inherent characteristics of the device; (2) 
characteristics of the device necessary for its safe and effective 
performance are well established; (3) changes in the device that could 
affect safety and effectiveness will either (a) be readily detectable 
by users by visual examination or other means such as routine testing, 
before causing harm, or (b) not materially increase the risk of injury, 
incorrect diagnosis, or ineffective treatment; and (4) any changes to 
the device would not be likely to result in a change in the device's 
classification. FDA may also consider that, even when exempting 
devices, these devices would still be subject to the limitations on 
exemptions.

[[Page 25890]]

III. Limitations on Exemptions

    FDA has determined that premarket notification is not necessary to 
provide a reasonable assurance of safety and effectiveness for certain 
class II clinical electronic thermometers subject to the limitations 
outlined in table 1. This determination is based, in part, on the 
Agency's knowledge of the device, including past experience and 
relevant reports or studies on device performance (as appropriate), the 
applicability of general and special controls, and the Agency's ability 
to limit an exemption.

A. General Limitations of Exemptions

    The exemption from premarket notification established in this order 
applies only to those devices that have existing or reasonably 
foreseeable characteristics of commercially distributed devices within 
that generic type (see Sec.  880.9 (21 CFR 880.9)). A manufacturer of a 
clinical electronic thermometer that otherwise meets the exemption 
described in 21 CFR 880.2910(b) would still be required to submit a 
premarket notification to FDA before introducing a device or delivering 
it for introduction into commercial distribution when the device meets 
any of the conditions described in Sec.  880.9.

B. Partial Limitations of Exemptions

    In addition to the general limitations, FDA may also partially 
limit an exemption from premarket notification requirements to specific 
devices within a listed device type when the Agency assessment 
determines that the factors laid out in the Class II 510(k) Exemption 
Guidance do not weigh in favor of exemption for all devices within a 
generic type of device. In such situations where a partial limitation 
of the exemption has been identified, FDA has determined that premarket 
notification is necessary to provide a reasonable assurance of safety 
and effectiveness for devices that fall outside of the limitations.
    As described in table 1, FDA is limiting the exemption for clinical 
electronic thermometers to devices that have validated specifications 
and performance via appropriate testing and analysis, such as analysis 
and testing in accordance with FDA-recognized editions of standards as 
appropriate. We added ``as appropriate'' to the third limitation in the 
codified language because a combination of standards may be necessary 
to fully assess the device. We recommend that manufacturers use the 
recognized consensus standards database for medical devices (available 
at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfstandards/Search.cfm) to determine the FDA-recognized standards and versions 
appropriate to their device by searching for the relevant product code.
    This order also excludes clinical electronic thermometers with 
telethermographic functions and continuous temperature measurement 
functions from the exemption from premarket notification. Examples of 
clinical electronic thermometers with telethermographic functions 
include a kiosk with integrated infrared thermometer, a stationary 
infrared thermometer affixed to a wall or ceiling, or a wheeled cart 
with integrated infrared thermometry function. Examples of thermometers 
with continuous temperature measurement functions include temperature 
probes intended to monitor body temperature during surgical procedures, 
temperature probes affixed to the skin of neonates or infants intended 
to monitor body temperature, thermometer patches affixed to the 
patient's skin, or thermometers that are swallowed to monitor a 
patient's body temperature. FDA considers premarket notification 
requirements for infrared clinical electronic thermometers with 
telethermographic functions and clinical electronic thermometers with 
continuous temperature measurement functions to be necessary to provide 
a reasonable assurance of safety and effectiveness because such 
thermometers include newer technology that may require additional 
testing beyond that specified in FDA-recognized standards, and have 
additional biocompatibility, interoperability, electromagnetic 
compatibility, electrical safety, and sterility considerations compared 
to clinical electronic thermometers without these types of functions. 
For example, an infrared thermometer kiosk is used as a stationary 
device, has a camera that captures a person's face, and uses a single 
infrared sensor. These technological characteristics necessitate 
additional testing beyond those specified in FDA-recognized standards 
to provide a reasonable assurance of safety and effectiveness.

IV. Class II Device

    FDA is identifying the following class II device that will no 
longer require premarket notification under section 510(k) of the FD&C 
Act, subject to the general limitations to the exemptions found in 
Sec.  880.9 and any partial exemption limitations identified in Table 
1.

----------------------------------------------------------------------------------------------------------------

    To reduce administrative burden, FDA has assigned new product codes 
to clinical thermometers with telethermographic functions, product code 
SDW, and to the exempt clinical electronic thermometers, product code

[[Page 25891]]

SDV. New product code SDW, which represents clinical electronic 
thermometers with telethermographic functions, has been named 
``Stationary Infrared Thermometer.'' Clinical electronic thermometers 
with continuous temperature measurement functions continue to fall 
under product code FLL. As such, FDA has revised the name of product 
code FLL from ``Thermometer, Electronic, Clinical'' to ``Continuous 
Measurement Thermometer'' to more accurately reflect the devices that 
fall within this product code. New product code SDV, which represents 
the class II exempt clinical electronic thermometers and reflects the 
partial exemption limitations, has been named ``Clinical Electronic 
Thermometer.'' This ensures that the non-exempt devices can be 
identified distinctly from devices that fall within the partial 
exemption limitation (i.e., exempt and non-exempt devices have distinct 
product codes).

V. Analysis of Environmental Impact

    The Agency has determined under 21 CFR 25.30(h) that this action is 
of a type that does not individually or cumulatively have a significant 
effect on the human environment. Therefore, neither an environmental 
assessment nor an environmental impact statement is required.

VI. Paperwork Reduction Act of 1995

    FDA concludes that this final order contains no new collection of 
information. This final order refers to previously approved collections 
of information. These collections of information are subject to review 
by the OMB under the PRA. The collections of information in part 807, 
subpart E, regarding premarket notification submissions have been 
approved under OMB control number 0910-0120; the collections of 
information in 21 CFR parts 800, 801, and 830, regarding labeling have 
been approved under OMB control number 0910-0485; and the collections 
of information in 21 CFR part 820 regarding quality system regulation 
have been approved under OMB control number 0910-0073.

List of Subjects in 21 CFR Part 880

    Medical devices.

    Therefore, under the Federal Food, Drug, and Cosmetic Act and under
