I have been trying to use my technology to answer the following questions:- 1.How many patients are recorded as having hayfever(H172-99) or allergic rhinitis - pollen (H170) in my practice? NB The code confusion is due to having a Read code conversion and a rescue.. I'll tell everyone the sad story if anyone is interested! 2.In the past 3 years,how many of these patients have received either kenalog or antihistamines?(The later may or may not have been prescribed for hayfever - and I have no record of OTC medication) Answers. 1.
