Create A Custom Column with and IF Statement that references values in a separate table.

[pbianalyst]

Good afternoon, 

I have a table with 25 columns to identify different diagnosis codes. I would like to create a custom column that flags whether any of the diagnosis codes (180) in another table are in any of those 25 fields. Is there a DAX statement or any other way that can help me accomplish that task in Power BI?

Thanks in advance for your help!

Trying to flag the Trigger Diags sounds like?  Something along these lines should work.  You would add this as a calculated column on the Claim table.

Trigger_Diagnosis = 
SWITCH (
    TRUE(),
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code1] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code2] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code3] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code4] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code5] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code6] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code7] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code8] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code9] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code10] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code11] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code12] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code13] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code14] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code15] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code16] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code17] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code18] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code19] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code20] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code21] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code22] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code23] ) ), "Y",
    NOT ISBLANK ( LOOKUPVALUE ( Trigger_Diag[Diagnostic_Code], Trigger_Diag[Diagnostic_Code], Claim[Diagnostic_Code24] ) ), "Y"
    )
