About the Co-location Code (CoLoCode™)


The exclusive CarePrecise CoLoCode is used to identify individuals and organizations providing medical services at the same location. CarePrecise computes a CoLoCode for the full database of 6.1 million U.S. healthcare provider records.* It can help in determining practice size, and in finding practitioners who are co-workers. It can also be used to find a Type 1 (individual) provider's Type 2 (organization) records(s) (Type 1 to Type 2 crosswalk), and to find the workers at a given practice group (workplace to worker crosswalk).

The CoLoCode is constructed using a proprietary algorithm that hyper-conforms practice location data for the 6.1 million US healthcare providers. Going well beyond the US Postal Service's "Pub 28" standard, the CoLoCode accounts for addresses that may have been entered very differently. For example, "2525 West 33rd Street, Suite 205" is understood to be the same location as "2525 W 33 #205," as well as many other variations.

To use the CoLoCode for these purposes, a query can be created that links all providers having the same CoLoCode, in a manner like this:


The "Names tables" are shown in the example, but you can also include address, phone/fax, and other tables.

The "CoLoCode table" is used twice in the query; the first one is the CoLoCode for the provider you want to find co-workers for, and the second one is going to pull all of the NPI numbers for people (and companies) listing that location for their place of practice. The same configuration works to locate the workplace (organization) name for a given worker.

The powerful CoLoCode feature is available only through CarePrecise.


*NOTE: The CoLoCode computation algorithm is great, but not absolutely perfect—exceptions do exist. CoLoCodes are available for approximately 99.999% of the 6.1 million U.S. HIPAA-covered healthcare provider records, with an accuracy rate higher than 98.5%.
