i'm not sure if dr sand will ever see this but their practice of paying up front even though my insurance is covering 100% of their allowable expense is ridiculous. for years i've been coming here and dr sand is wonderful. for the past month+ (yes month!) i've tried to contact carol in the billing office who was going to look into a difference of what insurance and i paid. i am owed about $100 and no one is returning my calls...carol, leanne nor do they care that they still owe me $$$. i am appalled and disappointed. the office says one thing and billing says another. no credit has been given as they indicated happens when a patient is owed $$$. also, on my last visit they INSISTED again to collect a co-pay/deductible. my insurance covered 100% o their costs. so basically i'm paying them additional $$$ when they owe me $$. he needs to revamp his office/billing staff for efficiency and customer service.
