How do you bill for a split-night sleep study?
For a split study, it is appropriate to report only the most extensive procedure code. For example, a PSG being performed on a patient over the age of 6 is initially identified by CPT® code 95810. If during the study it becomes necessary to apply CPAP to relieve episodes of apnea, at the point, the mask is applied CPT code 95811 now defines the procedure. It would be inappropriate to report both code 95810 and 95811, only 95811 would be billed because it is the more extensive procedure. The application of the CPAP should not be reported separately.
