Medical Coding

Answer: B - Z34.82, Z3A.16 is the correct ICD-10-CM code sequence for this patient encounter. Z34.82 is the correct code for a second trimester encounter for supervision of “other” normal pregnancy and this patient was specified to be in her second pregnancy. Code Z3A.16 is the correct code to indicate the number of weeks gestation that patient is being supervised at.

Code Z34.02 is incorrect because this code is for a normal first pregnancy encounter. Code Z3A.15 is incorrect because this code is for an encounter at 15-weeks’ gestation. Code Z34.01 is also incorrect because this code is for a normal first pregnancy in the first trimester.
