It is corporate insurance. In corporate OPD is covered.If the claim is legit, and comes under pre or post hosp, they pass it easily. I have personally done it for family members.
People try faking/getting hospitalized just for the sake of getting yearly checkup or MRI or x-ray done.
Then its obvious that they will deny for it.
Also ideally medical insurance should not be taken for OPD purposes.
Previously I had corporate insurance of kotak and uhcp. Never faced such problems
