A 17 year old patient was prescribed birth control pills for the first time and the diagnosis code used was Z30.011, encounter for initial prescription of contraceptive pills. The patient experienced side effects so a new prescription for a different pill was prescribed at her 3 month follow up. Is Z30.011 appropriate since it is a new prescription and pill type or would Z30.41, encounter for surveillance of contraceptive pills be correct?

After the initial prescription is written, is it ever appropriate to use Z30.011 again (e.g. whether repeat prescription or new pill type prescription at the ensuing annual visits)?

Thanks!
