Regular Expression Details

Title Test Find Medicare HIC Number (HICN)
Expression
^(00[1-9]|0[1-9][0-9]|[1-7][0-9][0-9]|7[0-7][0-2]|77[0-2])(\d{6})(A|B([1-9]?|[ADGHJKLNPQRTWY])|C([1-9]|[A-Z])|D([1-9]?|[ACDGHJKLMNPQRSTVWXYZ])|E([1-9]?|[ABCDFGHJKM])|F([1-8])|J([1-4])|K([1-9]|[ABCDEFGHJLM])|T([ABCDEFGHJKLMNPQRSTUVWXYZ2]?)|M|W([1-9]?|[BCFGJRT]))$
Description
This is the real regex for a non-railroad board HICN. All combinations are accounted for. This does not account for dashes as they are stripped out before I do the validation. This also only allows 001-772 as the first 3 numbers per spec. It does not take into consideration that 00 is not allowed for 4th and 5th digits and that 0000 is not allowed for last 4 digits.
Matches
123456789F1 123456789W
Non-Matches
1234567890 A000000 WCD000000 123-45-6789A

Title: Didn't account for T3-9.

Hi Derek, The T part of this regex doesn't account for T3-9. So it should be T([ABCDEFGHJKLMNPQRSTUVWXYZ2-9]?).
