SUGGESTED CPT CODES
CPT CODES
The suggested CPA codes are related to the SweatC, OXI_W and TBL-ABI systems.
TM FLOW System is a medical device data system (MDDS) that manages the data of the 3 systems. Therefore, It does not have any CPT codes.
LD technology systems are NOT automated devices. Our products require trained technician involvement, and our reports require qualified physician interpretation.
CPT CODING 95921 FROM CMS
OXI_W CPT CODING 95921 FROM CMS PROCEDURE DESCRIPTION
Testing of autonomic nervous system function; Cardiovagal innervation(parasympathetic function), including 2 or more of the following: Heart rate response to deep breathing with recorded R-R intervals, Valsalva Ratio, and 30:15 Ratio.
oxi_w method: Recording of the RR intervals at rest and during the Valsalva maneuver, Deep breathing, and standing up. The software calculates Heart rate response to deep breathing with recorded R-R intervals, Valsalva Ratio, and 30:15 Ratio.
CPT CODING 95923 FROM CMS
SWEATC CPT CODING 95923 FROM CMS PROCEDURE DESCRIPTION
Sudomotor-function testing is used to evaluate and document neuropathic disturbances that may be associated with pain. The quantitative sudomotor axon reflex test (QSART), thermoregulatory sweat test (TST), sympathetic skin responses, and silastic sweat imprints are tests of sympathetic cholinergic sudomotor function.
SweatC method: Sudomotor function testing and assessment using sympathetic skin response method
SWEATC AND ARTICLE A54954 OF NOVITAS
SWEATC AND ARTICLE A54954 OF NOVITAS
Sweat C is not an ESC device. The word ESC means Electrochemical Skin response.
The article A54954 states: “The device measuring ESC “consist of two sets of large-area stainless steel electrodes for the hands and feet that are connected to a computer for recording and data-management purposes. The electrodes are alternately used as an anode or cathode, and a direct current incremental voltage of ≤4 V is applied to the anode. Through reverse iontophoresis, the device generates voltage to the cathode and a current (intensity of around 0.2 mA) between the anode and cathode proportional to chloride concentration.”
SweatC shall NOT be considered in this category for the following reasons:
SweatC shall NOT be considered in this category for the following reasons:
1. It does not use steel electrodes for the hand and feet
2. It does not use incremental voltage. but constant voltage
3. It uses cloth electrodes (textile fibers) so no electrochemical reaction can be obtained, and therefore it cannot induce any reverse iontophoresis.
CPT CODING 93922 FROM CMS
TBL-ABI CPT CODING 93922 FROM CMS PROCEDURE DESCRIPTION
Limited bilateral noninvasive physiologic studies of upper or lower extremity arteries, (eg, for lower extremity: ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus bidirectional, doppler waveform recording and analysis at 1-2 levels, or ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus volume plethysmography at 1-2 levels, or ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries with, transcutaneous oxygen tension measurement at 1-2 levels).
TBL-ABI method: Ankle brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus volume plethysmography at 2 levels.
*DISCLAIMERS: The above checklist of CPT Codes is only suggested according to the cleared intended use of each LD Technology product, and it cannot be considered as a part of the device’s performance. The practitioner is solely responsible for compliance with the use of CPT codes, the medical necessity of the test, and related ICD-10’s according to the guidelines established by the AMA (American Medical Association) and CMS (Center for Medicare and Medicaid Services) Central Office per state or region. LD TECHNOLOGY shall not be liable for any changes from the AMA and/or CMS and/or for any financial damage resulting from the suggested CPT.
*It is the Physician’s sole responsibility to ensure that they have the knowledge, training, expertise, and accreditation to perform these tests. The accreditation requirements are provided by CMS. In addition, the technician running the measurement of the tests shall be trained and qualified.
