Health care is exempt to the extent it is not cosmetic in nature. Cosmetic treatment even if conducted in a hospital by a medical doctor would be taxable. Trails and opinions given by medical professionals on specimen or facts provided are taxable as the supply of services by the medical professional is not in respect of a patient or patient’s report for diagnosis or treatment.
