Modifier KX - documentation on file. Can someone please explain this modifier to me? Our Medicare carrier is telling us to put it on all of our DME's, but I don't completely understand the definition documentation on file or how it pertains the therapy caps, etc.
The Great Basin itself is a vast area of the western United States located primarily between the Rocky and Sierra Nevada mountain ranges, including areas of Utah, Nevada, California, Idaho, and Oregon.
The Great Basin is not a single basin, but rather a series of contiguous watersheds, bounded on the west by watersheds of the Sacramento-San Joaquin and Klamath rivers, on the north by the watershed of the Columbia-Snake, and on the south and east by the watershed of the Colorado-Green.
