A) nonsufficient funds check
B) ​collection agency transaction
C) ​credit balance
D) third party

A nonsufficient funds (NSF) check is a check that cannot be processed because the account it is drawn on does not have enough funds. When a medical office receives an NSF check, the amount of the check must be deducted from the office's checking account balance, as the expected funds are not available.
