Good design with Angular JS

I am a web developer working a web site/system in a very small company and in the angular controller there are statements like this..

if ((cover.coverPK == 6 || cover.coverPK == 8 || cover.coverPK == 10 || cover.coverPK == 4) && cover.coverDetailsCompleted > 0) { etc etc

Now these coverPKs are the SQL primary IDs to identify different insurance covers.. surely it is bad design to reference IDs like this on the front end, and a new developer joining will have no idea what the 6 is supposed to mean? unless they do a lookup in SQL.

Also, database IDs can change? which will break this code.

Thanks
