The CPT® Code 84392 refers to a laboratory test that measures the levels of sulfate in urine. This test is significant as it provides insights into an individual's dietary protein intake and overall nutritional status. Sulfate levels in urine are influenced by the consumption of protein, particularly from animal sources such as meat, fish, and poultry, which are rich in sulfur-containing amino acids like methionine and cysteine. When an individual consumes a high amount of animal protein, it can lead to increased excretion of sulfur and calcium in the urine. This elevated excretion may raise the risk of developing renal calculi, commonly known as kidney stones. Additionally, urine sulfates play a crucial role in the body's buffering system and in the exchange of hydrogen ions, which helps to regulate the supersaturation of uric acid in the urine. The test typically involves collecting urine over a 24-hour period, followed by analysis using quantitative spectrophotometry to accurately measure sulfate concentrations.

The urine sulfate test (CPT® Code 84392) is indicated for the following conditions:
The procedure for conducting the urine sulfate test involves several key steps to ensure accurate measurement of sulfate levels.
After the urine sulfate test is completed, patients may resume their normal activities. There are typically no specific post-procedure care instructions required. However, healthcare providers may discuss the results with the patient, including any necessary dietary adjustments or further testing if elevated sulfate levels are detected. It is important for patients to follow any additional recommendations provided by their healthcare provider based on the test results.

| 90 | Reference (outside) laboratory: when laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 to the usual procedure number. | GA | Waiver of liability statement issued as required by payer policy, individual case | 91 | Repeat clinical diagnostic laboratory test: in the course of treatment of the patient, it may be necessary to repeat the same laboratory test on the same day to obtain subsequent (multiple) test results. under these circumstances, the laboratory test performed can be identified by its usual procedure number and the addition of modifier 91. note: this modifier may not be used when tests are rerun to confirm initial results; due to testing problems with specimens or equipment; or for any other reason when a normal, one-time, reportable result is all that is required. this modifier may not be used when other code(s) describe a series of test results (eg, glucose tolerance tests, evocative/suppression testing). this modifier may only be used for laboratory test(s) performed more than once on the same day on the same patient. | GV | Attending physician not employed or paid under arrangement by the patient's hospice provider | GY | Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit | GZ | Item or service expected to be denied as not reasonable and necessary | Q3 | Live kidney donor surgery and related services |
