​​​​​​​​Soteria Medical, LLC provides a formal Operators Manual with each Platform along with complete on-site training and remote monitoring. 

The testing is noninvasive, safe, painless, rapid, relatively inexpensive, accurate, and easily learned. 


The current configuration for the Soteria Cardiac Platform includes five Modules. It is further noted that any combination of testing may be performed based on the preference of the Referring Physician. 

All patients must be registered.

​​Module 1 : Patient Demographics

From the Soteria Cardiac Platform Main Menu, the Registration button is depressed. Patient Demographics are inserted. We recommend the Patient ID be the patient's Social Security Number. If necessary, a Driver's License Number or other Number may be substituted. All information is considered confidential (HIPAA compliant) and will NOT be shared. The Operator identifies the parameter values and enters the material accurately and completely. It is helpful to obtain the full name of the Subject' s Referring Physician; this is entered under Physician. Careful assessment of individual Risk Factors is important. No patient charge (i.e. billing) is associated with Registration.









Module 2:  Framingham Risk Assessment and Body Mass Index

This module is accessed by depressing the Framingham and BMI button on the Main Menu. The Framingham Risk Profiles for CAD, Cerebrovascular Disease (i.e. Stroke), and Peripheral Vascular Disease are the most respected question and answer profiles in frequent use and known to be based on the largest and longest followed database in cardiovascular history. The Demographics and Risk Factors entered during Registration are carried-forward to this module. Body Mass Index (BMI) is automatically calculated and displayed.

 To display the Framingham Risk Analysis, a current blood pressure must be entered. The Operator has the option of entering characteristic Systolic and Diastolic Pressures or taking a current Blood Pressure with the built-in Noninvasive Blood Pressure (NIBP) System. With the blood pressure input complete, the three Framingham Profiles listed above are calculated and displayed. No patient charge (i.e. billing) is associated with Framingham and BMI.











​​Module 3: The ABIgram

This module is accessed by depressing the ABlgram button on the Main Menu. The demographic data is automatically transferred from the Registration Module to the ABlgram Module. The Procedures Box will prompt the Operator as to Blood Pressure Cuff placement. Measurements are taken at the brachia! and ankle levels bilaterally; cuffs are placed and connected in the order specified. Care should be taken to place the cuffs in the right location, orientation, and tension. This Module will activate the NIBP System automatically and measure Systolic Blood Pressure at the four specified levels. The results of these measurements are displayed on the screen.












​​This module returns Ankle / Brachial Index (ABI). This is the ratio of Ankle Systolic Pressure divided by Brachial Systolic Pressure. This measurement is indicated when a physician wants to have a simple physiologic assessment of the peripheral vascular system. If there is no significant drop in Systolic Pressure between the brachial level and the ankle level there is a degree of confidence that no high- grade arterial lesions are present throughout the aorta, iliac, common femoral, superficial femora/ popliteal, and tibial vessels. If, to the contrary, a reduced Ankle / Brachial Index (<0.90) suggests arterrial obstruction located between the brachial artery and the ankle level. It should be noted that this test does not specify the location of the obstruction(s).

It is also known that the presence of peripheral vascular disease is highly correlated with the presence of coronary artery disease. In fact, 90% of patients with symptoms of peripheral vascular disease have significant coronary artery disease. For this reason, physicians include ABI in the evaluation of coronary artery disease. It should be pointed out that peripheral vascular disease is a late marker of coronary artery disease and often develops a decade later than coronaryartery disease.

The CPT Code for the Soteria ABIgram is 93922. The full definition of this Testing Code is given in  AMA CPT 2013 Professional Edition (Page 524). For billing, the CPT Code must be paired with an approved ICD-9-CM Code. For 93922 the approved ICD-9-CM Codes are listed in Table 3.This was created from data supplied by SuperCoder.com. The national average for Global Medicare reimbursement for this code is $94.24. It should be noted that Global reimbursement is typically higher for those patients covered by Private Insurance Carriers.



Module 4: The  PADogram

This module is similar to the ABlgram and directed toward the peripheral vascular system, however, the PADogram in addition to taking bilateral systolic measurements at the brachia! and ankle levels, includes bilateral thigh and calf level systolic pressure measurements and returns obstruction level results. The PADogram is performed when more detailed information is necessary in the diagnosis of peripheral vascular disease.

 This module is accessed by depressing the PADogram button on the Main Menu. The demographic data is automatically transferred from the Registration Module to the PADogram Module. The Procedures Box will prompt the Operator as to Blood Pressure Cuff placement. Measurements are taken at the brachia!, thigh, calf, and ankle levels bilaterally; cuffs are placed and connected in the order specified. Care should be taken to place the cuffs in the right location, orientation, and tension. This Module will activate the NIBP System automatically and measure Systolic Blood Pressure at the eight specified levels. The results of these measurements are displayed on the screen. If pressure measurements are inaccurate, individual measurements may be repeated.


The CPT Code for the PADogram is 93923. The full definition of this Testing Code is given in AMA CPT 2013 Professional Edition (Page 524) . For billing, the CPT Code must be paired with an approved ICD- 9-CM Code. For 93923, the approved ICD-9-CM Codes are listed in Table 3 and mirror those used for 93922. 

When billing 93922 and 93923 on the same patient on the same day, Modifier 59 should be used.












Module 5: The Soterogram

The Soterogram is the flagship module of the Soteria Cardiac Platform and is accessed by depressing the Soterogram button on the Main Menu. The demographic data is automatically transferred from the Registration Module to the Soterogram Module. The Procedures Box will prompt the Operator as to Cuff placement and connection.

The Upper Extremity Cuff is placed at the brachial level to obtain Systemic Pressures at the beginning of the procedure and at the end of the procedure. These data is averaged in the analysis. Only one upper extremity is required for this testing. This means that the Operator must make a selection. The upper extremity used should be the extremity with the most normal arterial system. In other words, if possible, do not select an upper extremity in which there is known or suspected auxiliary, subclavian, or brachial arterial occlusion. This can be determined by history, radial pulse palpation, or previous blood pressure results. The Operator also has a choice regarding placement of the Lower Extremity Cuffs (Thigh and Calf levels). Asin the case of the upper extremity selection, the single lower extremity selected for testing should be the lower extremity with the most normal peripheral arterial circulation. This can be determined by history and peripheral pulse palpation (femoral, popliteal, and pedal levels).

The Soterogram is performed when a physician wants to obtain patient-specific atherosclerotic information. The Soterogram focuses on the disease state of the arterial wall and is therefore not blinded to disease not producing abnormal hemodynamics such as flow, velocity, and pressure abnormalities. 


A wealth of practical information is obtained during Soterogram Testing. First, brachial systolic pressure, diastolic pressure and heart rate are obtained twice over approximately 10 minutes. This is helpful in sorting hypertension and rate abnormalities. Next, the Arterial Volume Expansion per Cardiac  Cycle for a normalized 50 mmHg Pulse Pressure is accurately measured at the Calf and Thigh Levels.  These Calf and Thigh Measurements are combined into a single Soterogram Score, which is a patient- specific indication of Arterial Compliance (Δ volume / Δ pressure).


Atherosclerosis is present when Arterial Compliance is reduced. Compliance Measurements at the Calf and Thigh levels have been shown to correlate with Coronary Artery Atherosclerosis due to the fact that the distribution of proteins composing the arterial wall: elastin, collagen, and smooth muscle are very similar at these levels.

The measured Soterogram Score is compared to a Predicted Soterogram Score based on gender and age. The Predicted Soterogram Score was developed by studying normal subjects with no evidence of atherosclerosis and no cardiovascular pharmacy. These data allow for the comparison of Scores (Actual versus Predicted), calculation of Arterial Age (versus Actual Age), and Elasticity (measured versus predicted). Finally, another extensive dataset is used to predict the patient’s degree of Atherosclerotic Burden. A graphic is given illustrating Normal, Mild, Moderate,  and  Severe Atherosclerotic Burden. Please note that atherosclerotic burden is present even in young individuals (Table 4).

The CPT Code for the Soterogram is 93923. The full definition of this Testing Code is given in AMA  CPT 2013 Professional Edition (Page 524). For billing, the CPT Code must be paired with an approved ICD- 9-CM Code. For 93923, the approved ICD-9-CM Codes are listed in Table 3 and mirror those used for 93922. This was created from data supplied by SuperCoder.com. The national average for Global Medicare reimbursement for this code is $146.30. It should be noted that Global reimbursement is higher for those patients covered by Private Insurance Carriers.

When billing 93922 and 93923 on the same patient on the same day, Modifier 59 should be used.
