Which of the following pieces of information would be allowed as part of a limited data set

I don't know. I'm just writing so I can get points on this.

Birth Date

Explanation: A limited data set is middle ground between identifiable and de-identified information. In a limited data set, most identifying information has been removed. It must not include any of the individual identifiers [45 CFR 164.514(e)]. Limited data sets don’t directly identify a patient, but they may contain some identifiers. The following identifiers may be included as part of a limited data set:

* Geographic data (town, city, state, and ZIP code, but no street address)

* Dates relating to an individual (birth date, admission and discharge dates)

* Unique identifying numbers, characteristics, or codes other than those listed under individual identifiers

well when looking at this if you think about it   negativley and positivley   react with each other and when the first layer gets full they add layers it starts with 2 on the first layer and it constantly goes on until the official number is there

because health skills are tools and strategies and also practical skills are also something you need to learn (like tools and strategies) and put it in reality.
