CPT® Code 94760

The CPT® Code 94760 refers to a noninvasive procedure known as ear or pulse oximetry, which is utilized to measure the oxygen saturation levels in the blood. This procedure is essential for monitoring the percentage of hemoglobin (Hb) that is saturated with oxygen, thereby helping healthcare professionals detect any lower than normal levels of oxygen in a patient's bloodstream. The process involves the use of an oximeter, a device that not only measures oxygen saturation but also records the pulse rate and provides a graphical representation of blood flow past the probe. During the procedure, a probe is typically attached to the patient's earlobe or finger, which is then connected to a computerized unit. The oximeter emits light at two different wavelengths from the probe, which is partially absorbed by the hemoglobin in the blood. The degree of absorption varies depending on whether the hemoglobin is saturated or desaturated with oxygen. The oximeter's processor computes the absorption data from the two wavelengths and displays the percentage of oxygenated hemoglobin. Additionally, the oximeter can be programmed to activate an audible alarm if the oxygen saturation level falls below a predetermined threshold. For a single determination of oxygen saturation, the appropriate code to use is 94760, while codes 94761 and 94762 are designated for multiple determinations and continuous overnight monitoring, respectively.
