Cuda - My brother-in-law is a radiologist in Indy, where they have a Gamma knife at the IUPUI hospital. This is his take:
"It doesn't state if he has private insurance or not. No one can refuse a patient treatment. His insurance company, however, can refuse payment if they deem it's 'out of Network'. Some insurance companies will pay 50% if a patient goes 'out of network'.
If he is eligible for Medicaid, it doesn't matter where he is treated. If he does not have a Medicaid card, he should apply ASAP. Like I said earlier, Medicaid will pay for services up to 90 days past the date of treatment.
He needs to contact Patient Accounts and they will help him apply for Medicaid, if he fits the financial constraints. If he has private insurance, they will also do their best to get as much of his proceedure covered, since they have a vested interestd in getting paid. Patient accounts are very well versed with all the private insurance payors as well as Medicare/Medicaid.
He needs to contact his insurance company directly and explain the situation. Next, his neurologist must send a letter of need to prove this treatment is superior to other forms of external beam radiation therapy. Acoustic Neuroma's are slow growing tumors but they have a relatively high rate of local recurrance.
I hope this helps."
