Certified Coding Specialist (CCS) Practice Exam

The correct code for dilation and curettage (D&C) for retained products of conception after an abortion at 11 weeks' gestation is 10A07ZW. This code is specifically used to describe the procedure of dilation and curettage, which involves the removal of tissue from the uterus.

The first two characters of the code, "10", indicate that it falls under the category of obstetrical procedures. The next character, "A", represents a specific procedure within this category, which refers to dilation. The following two characters detail the type of approach used—in this case, "07" signifies it is a curettage procedure. The "W" at the end denotes that the procedure was performed due to retained products of conception, which is an important detail given the context of the abortion at 11 weeks' gestation.

In contrast, other codes provided in the options do not accurately reflect the procedure or context described. For instance, codes with different last characters or those that do not specify the complication of retained products of conception would not capture the clinical scenario appropriately. This specificity is crucial in medical coding to ensure accurate representation of procedures for billing and health records.
