Coding & Reimbursement Testing for Tear Osmolarity? How to obtain reimbursement for this dry eye diagnostic By Suzanne L. Corcoran, COE. Increasing recognition of dry eye disease means increasing use of laboratory tests to diagnose it. Here’s what you’ll need to know to obtain reimbursement for these treatments.Tear osmolarity was measured using an in vitro diagnostic device (TearLab™ Osmolarity System, TearLab™ Corp., San Diego, CA) designed to take a 50 nL sample of tears. As noted previously, the test was performed prior to instillation of the lubricant eye drops and then a final time 5 min after instillation of the drop. Tear osmolarity was . The TearLab Osmolarity System (TearLab Corporation) is an objective and quantitative test for diagnosing and managing Dry Eye patients. The system is intended to measure the osmolarity of human tears to aid in the diagnosis of dry eye disease in patients suspected of having dry eye disease, in conjunction with other methods of clinical evaluation.

Dry eye is a disease, so performing a TearLab Osmolarity test to determine a proper diagnosis is the first step toward relief. Osmolarity is the accepted standard for diagnosing Dry Eye Disease. The TearLab Osmolarity Test will give your doctor a meaningful measurement of the health and stability of your tear film. Once your eye doctor has determined your osmolarity . Three of the recent tests that are becoming more widely used are the TearLab osmolarity test, the InflammaDry test from Rapid Pathogen Screening and the TearScan Micro-assay System from Advanced Tear Diagnostics. The TearLab test measures the concentration of electrolytes in a 50-µl sample of a patient’s tears; higher levels indicate a .

Abnormalities of tear osmolarity, i.e. hyperosmolarity has been reported to be key to the mechanism and pathogenesis of DED, 9 therefore measurement of tear osmolarity was anticipated to be an appropriate metric for diagnosis and following treatment of DED, especially with the introduction of a point of care test in 2009 (TearLab Osmometer). Testing osmolarity Rather than relating vision problems to dryness or irritation, I check the tear osmolarity (TearLab Osmolarity System, TearLab). If the osmolarity is below 308 mOsm/L or there is an inter-eye difference above 8 mOsm/L, then I know that the patient may have dry eye disease, even in the absence of symptoms.
