Gst on medicines used in hospital

Yes, but GST not to be charged extra...

Agreed with dhiraj lal ji sir just want to add that you have to pay gst to govt. as follow suppose your medicine cost is of rs 118 (assume your medicine fall under 18/ gst slab) then 18 rs is considered for gst and 100 rs for medicine .
secondly although it is composite supply but The main Entry No: 82 of Exemption List
 a. Health care services by clinical establishment, an authorized medical practitioner or Para - medics;

b. Services provided by way of transportation of a patient in an ambulance, other than those specified in above. 
so you have to find slab for ur medicine and by reverse calculation find the amount of gst.

But composit dealer cannot collect tax from customer so if sells on MRP ie 100/- he is liable to collect only 100 from customer but has to deposit GST on 100/-.

yes pankaj ji dats y I m trying to explaining how to find gst amount by doing reverse calculation

I am working in a Hospital and we planned to bill medicine to Inpatient and Out patient as follows:

                                             Sale Value       GST        Total     MRP

Out Patients                              100               12          112        112

Inpatient                                    112                             112.        112     [This amount to be shown in Discharge bill]

Input Tax to be claimed on Pro rata basis :- Based Exempted and Taxable Sales, on monthly basis.

Is this is a correc method ?. I have doubts over Inpatients Sales value. ie  100 OR 112 ?

Please advise
