Question

In some cases we need to left pad the patient id in PID-3 with leading zeros so that the patient id is a specifed length.

Answer 1

You can use StringUtils to pad a string to a specified length.  Do something like this:

 

var pid3 = "129018";

var desiredDigits = 10;

var padChar = "0";

StringUtils.leftPad(pid3, desiredDigits, padChar);
