I hope it works out to mostly be deductible for you.
We have a $20 copay, no deductible and a $5 prescription charge. We still managed to pay out just under $13,000 if you count our premiums ($500/month) and dental ($3,000) I swear somebody gets sick every week around here, including some out of network visits from our vacation.
In addition to that, we have to buy all sorts of allergy medicines and creams for our 3 year old, none of which count as medical expenses. He is also allergic to eggs, wheat, soy, milk, shellfish and nuts- so our grocery bills have more than tripled and the IRS couldn't care less. (Almost wish he had a celiac's diagnosis because it would make no difference except food becomes a deduction!)
If you added in the allergy meds and difference in food costs we would get pretty close to your $18,000... I'm curious how high it will get this year, the baby has hypotonia and goes to PT weekly now.
I don't feel like our medical expenses are normal.
