Deduction under sec 80ddb

i have read some where that treatment must be compulsorily done in a govt. hospital.

S.80DDB reads as follows :

"Provided that no such deduction shall be allowed unless the assessee furnishes with the return of income, a certificate in such form, as may be prescribed³⁵, from a neurologist, an oncologist, a urologist, a haematologist, an immunologist or such other specialist, as may be prescribed³⁵, working in a Government hospital "

In my view only certificate needs to be obtainted from specialist working in a Govt Hospital,treatment can be done any where .
