You can try as below :

declare @list varchar(MAX), @i int
select @i=0, @list ='4,7,12,22,19,'

while( @i < LEN(@list))
begin
    declare @item varchar(MAX)
    SELECT  @item = SUBSTRING(@list,  @i,CHARINDEX(',',@list,@i)-@i)
    select @item

     --do your stuff here with @item 
     exec p_MyInnerProcedure @item 

    set @i = CHARINDEX(',',@list,@i)+1
    if(@i = 0) set @i = LEN(@list) 
end
