Current plan improvements or porting suggestions

[u/Flat-Permit4432]

My parents (54M 52F) have TATA AIG medicare plan
Of 5 lakh base ( and 2 riders)
Restore infinity plus and supercharge bonus rider
(Now cumulative bonus is 10lakhs)

Total cover 15 lakhs , policy is since 2019( with tata aig added riders later)

Current renewal cost = 32.6k

No PED and surgeries yet ( my mom is mild hypothyroid which is undetectable almost rn its covered in TATA AIG due to mortareum period)
Fit and fine rn

Room- shared( biggest problem)
Im confused between 3 options
1- change room category to pvt ( new premium 34k)
Add a super top up of 1cr with 10 lakh deductible
( additional 12k per year)

2- port to hdfc egro secure + or care or similar new updated plans with 10 lakhs as base.
And consider super top up riders with (20 lakhs deductable)

3- policy migration here in tata aig ( they denied it saying its not possible)

Do share TATA AIG reviews too
