A bilateral procedure was performed.

Explanation: bilateral procedures require a modifier (commonly CPT modifier -50, or separate line items with -RT and -LT depending on payer rules) to indicate both sides were treated. The other options are handled differently: an initial service normally uses the standard code (no modifier), a cancelled/discontinued procedure uses discontinuation modifiers (e.g., -53, -73) only in specific circumstances, and using an unspecified code is a coding choice rather than a modifier situation.
