crosswalking
 n.— «Reynolds wouldn’t disclose the expected cost of the NPI project, saying only that it affects about 35% of the applications at Blue Cross and Blue Shield and 50% of its business processes. The insurer will maintain its internal legacy ID numbers and match them to the NPIs, a strategy commonly called crosswalking.» —“Federal ID Mandate Tests Health Insurers” by Heather Havenstein Computerworld July 17, 2006.
