Description

Possibly used in Form Locator (FL) 32-35 in the UB-04 form.

The CMS write (in their R81CP document):- "Occurrence and occurrence span codes are mutually exclusive.

  • Occurrence codes have values from 01 through 69 and A0 through L9.
  • Occurrence span codes have values from 70 through 99 and M0 through Z9."

This regex matches both types of codes, and assumes the letters must be upper case
