We have had a few cases of people getting anaplasmosis from tick bites. They are still being treated with antibiotics. How would I code this?
Through the alpha index, the code for anaplasmosis is A77.49 (Other ehrlichiosis).
For the bite itself, look up bite by site, superficial, insect in the alpha index. To me, if the patient is being treated with PO antibiotics, it would be 7th character "D" and for IV antibiotics it would be "A."
That's how I would code it.
