Fortis Hospital - Uneven medical billing

My uncle, S.Ramamurthy [UHID: *******] was admitted on **th July for ** days at the Fortis hospital, Nagarabavi, Bangalore. He holds a CGHS health card as he was a central government employee.

Non-Medicals: A whopping amount of **,*** rupees has been charged to me. Never seen or heard of such amount charged as non-medicals. Since my uncle passed away at the hospital late in the evening, i had to make this payment to get his body. There were none from the billing section to explain the billing, apart from collecting the payment. I am sharing the irregular way of billing, which would certainly raise questions about the usage of items that are part of it.
a. It was told to me that non-medicals was charged separately, but there are doctor consultations present in the bill summary. They say it is because ISRO pays them only for one doctor a day. The patient has to pay the money for other doctors visited.
b. My uncle was in isolated ICU on **th and **st of July. The billing shows PPE kit used on *st August as well. He was moved to the ward and back to ICU in the coming days. I can see another PPE kit used after moving him to regular ICU. He was being visited by the doctor in ward and ICU. What is the necessity of using a PPE kit again? Looks like it has been billed without any logic. Similarly there is another entry for PPE kit on **th Aug. This was for what?
c. In a diaper pack, there would be * diapers [as informed by the nurse at the hospital]. It appears that ** diapers were used on one single day as per the two entries that i can see in the billing dated **st July. My uncle was under liquid diet all through the stay at the hospital. When i asked the PRO and nurses they did not give a convincing response.
d. I have been charged **** per day for using the same bed sore material for ** days [Huntleigh Numbus * Bed Per Subsequent day]. This should have been billed only once as they did not use a new one everyday.
e. Examination gloves: Around **,*** Rupees has been charged by using *,*** gloves in ** days of his stay at the hospital. In the attached bill, from item ***, the billing has been revisited and enormous amount of gloves are added to the billing. So clearly they are all round numbers in quantity. Why were so many items again added with older dates?
