When it is appropriate to bill 77073—bone length studies (orthoroentgenogram, scanogram)—with the following codes?
|73562||Radiologic examination, knee; 3 views|
|73564||Radiologic examination, knee; complete, 4 or more views|
It would be rare that both 77073 and 73562/73564 would be reported together.
You would need separate orders and medical necessity for the knee views separate from the bone length exam. Any knee images taken as part of the scanogram would be included in 77073.
