Your level is not too elevated. There are several causes of increased bilirubin. Given that you have no other issues with the liver (all enzymes are normal, etc.) it seems less likely that you are experiencing liver failure causing your elevation.
If, for some reason such as a viral infection or medication reaction, you had some increased breakdown of red blood cells your bilirubin levels can go up transiently.
Another common cause of an elevated bilirubin level is a condition called Gilbert's disease. This is a condition where the liver does not process bilirubin properly, leading to slightly elevated bilirubin levels. It is a harmless disease.
I would recommend you have your level repeated. If it remains elevated, I would strongly suspect Gilbert's disease but would recommend that you see a GI specialist to get an expert opinion.
