Fidelis Care Career Events

Fidelis Care would like to remind providers of the appropriate coding modifiers to use when billing for a surgical or diagnostic procedure that was discontinued or stopped prior to completion for both facilities and physicians. 

Modifiers 73/74 are specifically used by facilities, to indicate that a procedure was discontinued or stopped prior to completion.  Coinciding with these facility modifiers, physicians should bill modifiers 52/53, which also indicates that a procedure was discontinued or cancelled.  If a procedure has been discontinued, both facility and physician claim submissions should reflect the discontinuation, by using the appropriate modifier codes below.

Facility Modifier Codes:

• Modifier 73: Discontinued outpatient or ambulatory surgery center procedure before anesthesia is administered.

• Modifier 74: Discontinued outpatient or ambulatory surgery center procedure after anesthesia is administered or after the procedure has started.

Physician Modifier Codes:

• Modifier 52: A service or procedure was partially reduced or eliminated at the provider's discretion or due to patient factors.

• Modifier 53: A procedure was terminated due to unforeseen circumstances or factors that threaten the patient's well-being, and the procedure was not completed.
