Status (as of April 28, 1998)

There is complete statewide DRG coverage for North Carolina; a complete table is listed below. Complete statewide coverage was achieved in September 1997. The DRGs are available on CD-ROMs in TIFF format. Most CD-ROMs contain 64 --7.5-minute quadrangles; some contain only 32 -- 7.5-minute quadrangles because of production quirks. In addition, each CD-ROM contains corresponding 1:100,000 (100K) and 1:250,000 (250K) sheets. Each CD-ROM costs $12.50 which includes shipping and handling; there is 6% state sales tax for orders destined to NC addresses. There are no discounts for multiple CD orders or for government agencies. Use the following index to help address specific questions you may have:
