Which modifier can be added to codes for CPT radiology services?

The modifier that can be added to codes for CPT radiology services is the -59 modifier. This modifier is used to indicate a "distinct procedural service." It allows coders to report that a procedure or service was performed separately from other services on the same date, even if the procedures are typically bundled together under standard coding guidelines.

In the context of radiology, if a radiology service is performed on a patient and it is separated from another procedure, using the -59 modifier ensures that each service is properly accounted for and reimbursed appropriately. For example, if a radiologist reads multiple imaging studies that might normally be bundled into one payment, the -59 modifier can clarify that each study should be billed separately because they are distinct services.

Modifiers like -52, -76, and -22 serve different purposes. The -52 modifier indicates a reduced service, the -76 modifier is used for repeat procedures by the same physician, and the -22 modifier signifies an increased procedural service. However, these modifiers are not specifically designated for distinguishing separate procedural services in the context of radiology like the -59 modifier is. Thus, -59 is the correct choice for indicating distinct radiology services that may otherwise be bundled together.
