c# - Validate ICD-10-CM -

has written validation (regex or otherwise) icd-10-cm?

i'm not interested in trivial solution (3-7 alphanumeric), i'd know how incorporation of 7th digit requirement handled.

i didn't write regular look icd-10-cm i've written lookup engine. can same parsing official xml file sql database, , searching database code (if no results found, code invalid). unfortunately, cannot post code here due various ndas should trivial same. benefits you'll valid codes (and not codes "look" icd-10-cm invalid, regex).

alternatively (and wouldn't recommend it) can full-text search on xml file on top of simple regular expression, it'll buggy (from experience).
