I recently had a slip and fall in my home and broke my shoulder. I went to the ER and have a $1500 bill from it (my deductible). ER doctor referred me to an orthopedic doctor who found my injury was caused by the slip and fall but my bone broke because i had a benign bone cyst in my shoulder. I'm wondering if this is still considered an accidental injury or if the bone cyst would be a "pre-existing condition" that negates coverage.
