When can ZIP codes be incorporated into de-identified information?

Covered entities can include the initial three digits associated with ZIP rule if, in line with the current publicly available information through the Bureau regarding the Census: (1) The geographical device created by combining all ZIP codes with the exact same three initial digits contains significantly more than 20,000 individuals; or (2) the original three digits of a ZIP rule for several such geographic devices containing 20,000 or less individuals is changed to 000. This means the first three digits of ZIP codes could be contained in de-identified information except whenever ZIP codes support the initial three digits placed in the dining dining Table below. The first three digits must be listed as 000 in those cases.

OCR published a rule that is final August 14, 2002, that modified particular criteria within the Privacy Rule. The preamble for this rule that is final the first three digits of ZIP codes, or ZIP rule tabulation areas (ZCTAs), that has to switch to 000 for launch. 67 FR 53182, 53233-53234 (Aug. 14, 2002)).

Using 2000 Census information, the after three-digit ZCTAs have populace of 20,000 or less individuals. All records with three-digit ZIP codes corresponding to these three-digit ZCTAs must have the ZIP code changed to 000 to produce a de-identified data set utilizing the safe harbor method. Covered entities must not, nevertheless, are based upon this listing or the one based in the August 14, 2002 regulation if more present information has been posted.

The 17 limited ZIP codes are:

The Department notes why these three-digit ZIP codes are derived from the five-digit ZIP Code Tabulation Areas produced by the Census Bureau when it comes to 2000 Census. This brand new methodology also is shortly described below, as it’s going to be of great interest to all or any users of information tabulated by ZIP rule. The Census Bureau will never be producing documents containing U.S. Postal Service ZIP codes either within the Census 2000 item show or as a post Census 2000 item. Nevertheless, as a result of the interest that is public’s having data tabulated by ZIP rule, the Census Bureau has established a brand new analytical area called the Zip Code Tabulation Area (ZCTA) for Census 2000. The ZCTAs had been built to over come the functional problems of developing a well-defined zip rule area simply by using Census blocks (while the details present in them) once the foundation for the ZCTAs. In the past, there is no correlation between ZIP codes and Census Bureau geography. Zip codes can get a cross State, spot, county, census tract, block team, and census block boundaries. The designations that are geographic Census Bureau utilizes to tabulate information are reasonably stable with time. For example, census tracts are merely defined every 10 years. In contrast, ZIP codes can frequently change more. The Census Bureau has no file (crosswalk) showing the relationship between US Census Bureau geography and U.S. Postal Service ZIP codes because of the ill-defined nature of ZIP code boundaries.

ZCTAs are generalized area representations of U.S. Postal provider (USPS) ZIP rule solution areas. In other words, each is built by aggregating the Census 2000 blocks, whose details work with a offered ZIP rule, as a ZCTA which gets that ZIP code assigned as the ZCTA rule. They represent almost all USPS five-digit ZIP rule discovered in a given area. For all those places where it is hard to look for the prevailing five-digit ZIP rule, the higher-level three-digit ZIP code is employed when it comes to ZCTA rule.

What exactly are types of times which are not allowed based on the secure Harbor Method?

Aspects of times that aren’t allowed for disclosure through the time, thirty days, and just about every other information this is certainly more particular compared to the year of a conference. As an example, the date “January 1, 2009” could never be reported as of this standard of detail. Nonetheless, it may be reported in a data that are de-identified as “2009”.

Numerous documents contain times of solution or any other events that imply age. Ages that are explicitly stated, or suggested, as over 89 yrs old needs to be recoded as 90 or above. As an example, if the patient’s year of birth is 1910 in addition to 12 months of health care solution is reported as 2010, then within the de-identified information set the season of delivery should really be reported as “on or before 1920. ” Otherwise, a receiver associated with the data set would discover that the chronilogical age of the individual is about 100.
