Final answer:
The patient should be charged $144. The fee, payment, adjustment, and new balance on the day sheet should be $160, $0, $16, and $144 respectively.
Step-by-step explanation:
The MA should charge the patient $160 - (10% of $160) = $144.
On the day sheet:
- Fee box: $160
- Payment box: $0
- Adjustment box: $16
- New balance box: $144
The adjustment is a debit adjustment because it is reducing the total charges for the patient.
If the MA discovers an unexpected box checked on the superbill, she should confirm the correct charges with the physician or another supervising staff member.
