Question : T-SQL Help Needed - Case Statement Help

I need assistance with the following line of code:

CASE WHEN Cast(PI.EligibilityNotes as varchar(8000)) like '%IHC%' THEN 'Yes' ELSE 'No' END AS [IHC Patient],

Previously, this was ok and working .... then the client came back and added a small twist to it. They mentioned they used "Declined IHC" or "Decline IHC" (ommitting the d) --- thus making this a 'No". So they are using IHC by itself as a 'YES' and a "Declined IHC' or a 'Decline IHC' for a 'NO'.

Can someone lend me a hand here?

My query:
