The REEVUE measures the oxygen that the body consumes. Using this measurement it calculates a patient’s Resting Energy Expenditure (REE), commonly referred to as a Resting Metabolic Rate (RMR). Physicians can screen for abnormally low metabolic rates and pinpoint the precise caloric intake required for weight loss, maintenance, or weight gain. Applications include nutritional assessments required to treat obesity as well as obesity related diseases such as metabolic syndrome, sleep disorders, diabetes, and thyroid disorders. Under strict laboratory protocol, the ReeVue can be used to measure basal metabolic rate (BMR). To download a ReeVue product brochure, click here.
Pre-Test RequirementIt is desirable to measure a person’s metabolic rate at a true resting level. To ensure one is at rest, we recommend the following preparation:
- Avoid eating a meal 4 hours before the test.
- Avoid exercising on the day of testing.
- If possible, avoid the use of stimulants such as caffeine prior to testing.
- During the test it will be important to get into a comfortable position and relax as much as possible.
- Keep lips sealed lightly around the mouthpiece. It is important that all the air breathed out is analyzed by the ReeVue™.
Conduct a Test
- Turn on the ReeVue™ and wait while it automatically calibrates. The machine will indicate when calibration is complete. It is important that no hose or filter be attached during calibration.
- Expand the MetaBreather hose to its full length (5 feet) and connect it to the ReeVue™. Be sure to use only a KORR™ manufactured MetaBreather as use of any other breathing device will not insure accuracy and will void your KORR™ factory warranty.
- Have the patient place the nose clip on his nose and the mouthpiece in his mouth, using his lips to seal around the edges. The patient should be relaxed and breathe normally.
- After approximately 10 minutes, the ReeVue™ will end the test and prompt the tester to enter in patient data to compare patient results to averages. The results can then be printed out.
CPT CodesIndirect calorimetry is CPT coded and is covered by Medicare and most insurance providers. If you have any questions about insurance coverage, contact insurance providers directly.

Diagnosis Codes – Weight LossCPT codes must be accompanied by an appropriate diagnosis code (ICD-10). Weight Management: Medicare Nationally Covered Indications currently reads: “services performed in connection with the treatment of obesity are covered by Medicare when such services are an integral and necessary part of a course of treatment for diseases such as hypothyroidism, Cushing’s disease, hypothalamic lesions, cardiovascular diseases, respiratory diseases, diabetes, and hypertension.” The AMA* cites that diagnoses codes supporting the medical necessity of Indirect Calorimetry include:
- E88.81 Metabolic Syndrome
- E88.9 Metabolic Disorder, Unspecified
- G47.00 – G47.9 Sleep Disturbances
- R06.02 Shortness of Breath
- Z79.899 Long Term Use of Other Medications
- R94.8 Abnormal results of function studies of other organs and systems (High or low metabolic rate)
Diagnosis Codes – NutritionCPT codes must be accompanied by an appropriate diagnosis code (ICD-10). Nutritional Assessments
- R94.8 High or Low Metabolic Rate. Abnormal results of function studies of other organs and systems
- Z71.3 Dietary surveillance and counseling

Resting Metabolic Rate (RMR) is a VITAL SIGN for treating Overweight & Obese PatientsIn 2006, the Northwestern Comprehensive Center on Obesity tested the RMR of 76 of their female patients. 17% of them would not have lost weight on the standard “1200 calorie a day” diet. In fact, they probably would have gained from 5 to 32 pounds in one year. Yet there were no other indicators that set them apart from those who could lose weight on that same diet. Is it any wonder patients are frustrated? For more information on the Northwestern Study, view this video
So what can a doctor do?
ASSESSA simple 10 minute RMR test can accurately pinpoint how many calories a patient needs to consume to lose weight.
TEACHShowing a patient the results of their own metabolic test gives you the opportunity to teach solid scientific principles within the context of their own bodies. Studies show that this is the ideal circumstance to elicit behavior change.
REFERArmed with a proper medical assessment, your patient is now ready to be referred to a weight loss expert. You may have an expert program set up within your practice. Or you may want to refer to a Bariatrician or community based program. Your KORR representative will be happy to assist you with this next step.

ReeVue Frequently Asked Questions
How long does the test take?
The test takes approximately 10 minutes.
How many tests can you do on the machine?
The ReeVue™ will perform an unlimited number of tests.
Can the disposable hose be used more than once?
The disposable hose (the METABREATHER™) is for single patient use only. It cannot be effectively cleaned between patients and the valves within the mouthpiece will not maintain accuracy through multiple tests.
Is certification required to operate the machine?
No certification is required. With its simple one button operation, anyone can be trained to operate the ReeVue™ in just minutes.
What kind of warranty do the products come with?
All KORR™ products come with a full 2 year warranty which includes all parts and labor. Routine maintenance is not covered under warranty. A renewable warranty is available to purchase for subsequent years.
What happens if the machine needs any maintenance?
All maintenance and repairs are performed at KORR™ Medical’s Service Center in Salt Lake City, Utah. The ReeVue requires oxygen sensor replacement and recalibration every 20-24 months.
