Patient Cell Phone Number in HL7 ADT

What version 2.2, 2.3, 2.3.1, etc.?

If 2.3 or higher, PID-13 is an XTN type field. With that there is a component which describes the type of Telecommunication equipment and CP is for Cell Phone.

For backward compatability the first occurence of the field is the primary telephone number (but could be Cell or other). Also the telephone number itself is to be formatted or componetized such as:

(718)428-3333^PRN^PH      (PRN for Primary Residence Number; PH for Telephone

or

^PRN^PH^^^718^428^3333

or

(718)428-3333^PRN^PH^^^718^428^3333

The second ocurence then could be

(212)111-1111^ORN^CP    (ORN for Other Residence Number; CP for Cellular Phone)

or

^ORN^CP^^^212^111^1111

or

(212)111-1111^ORN^CP^^^212^111^1111.

Check Chapter 2 of the HL/7 specifications for the format of XTN and the recommended codes for Telecommunication Use and Telecommunication Type.

However, most vendors don’t follow the standard very well.
