HCPCs --> Procedure Codes?

@Christian_Reich or @Dymshyts,

Question - should HCPCs like this map somewhere:

HCPC-S3819-Complete gene sequence analysis; brca2 gene

Why couldn’t this go here?

4226283 - 	BRCA2 mutation carrier detection test

Some of the HCPCs are stranded on their own island, specifically 1,946 in 20160817, in terms of standard terminologies.
